Multiple Myeloma Symptoms: Signs, Causes and Diagnosis

Multiple Myeloma Symptoms: What They Mean and How It Is Diagnosed

Multiple myeloma is a cancer that begins in plasma cells, a type of white blood cell found mainly in the bone marrow. Plasma cells normally produce antibodies that help the immune system respond to infections. In multiple myeloma, abnormal plasma cells multiply and accumulate in the bone marrow.

The effects of this abnormal growth can extend beyond the bone marrow. Myeloma can weaken bones, reduce the production of normal blood cells, increase the amount of abnormal protein in the blood or urine, raise blood calcium levels and sometimes damage the kidneys.

One important point is that multiple myeloma does not have one specific symptom that identifies it. Bone pain, fatigue, anemia, infections or abnormal kidney tests can occur for many different reasons. Diagnosis requires appropriate medical testing rather than symptoms alone.

What Is Multiple Myeloma?

Multiple myeloma is also called plasma-cell myeloma. It develops when abnormal plasma cells accumulate in the bone marrow.

Normally, plasma cells are part of the immune system. They produce antibodies that help recognize and respond to infections. Myeloma cells are abnormal and can produce an abnormal immunoglobulin or part of an antibody, often referred to as an M protein or monoclonal protein.

As myeloma cells increase, they can interfere with normal bone-marrow function and affect the surrounding bone.

This can produce several major problems:

• fewer healthy red blood cells, causing anemia

• reduced production of some white blood cells, increasing infection risk

• reduced platelet production in some people, increasing bleeding or bruising risk

• weakening or destruction of bone

• increased blood calcium

• kidney injury associated with the disease and its abnormal proteins

Not everyone with multiple myeloma has all of these problems, and some people initially have few or no symptoms.

Why Can Multiple Myeloma Affect So Many Parts of the Body?

The bone marrow is not simply a storage space for blood. It is where many blood cells are produced.

When abnormal plasma cells occupy increasing amounts of marrow, normal blood-cell production can be affected. At the same time, myeloma-related changes in bone can cause areas of bone destruction and release calcium into the bloodstream.

Myeloma proteins can also contribute to kidney injury.

This explains why the disease may produce symptoms involving several apparently unrelated systems.

The important relationship is:

abnormal plasma cells → bone-marrow and bone involvement → blood, bone, calcium and kidney complications.

Bone Pain and Bone Weakness

Bone problems are among the better-known manifestations of multiple myeloma.

Pain can occur in several areas, particularly the:

• back

• ribs

• hips

• skull

• other affected bones

The pain is not simply because the cancer is "inside the bones." Myeloma can alter normal bone-remodelling processes and produce areas where bone becomes weaker.

Some people develop fractures after relatively minor stress or injury.

Persistent or unexplained bone pain does not mean a person has multiple myeloma. Back pain, for example, is extremely common and has many causes.

However, persistent bone pain combined with unexplained anemia, abnormal kidney tests, high calcium, recurrent infections or other concerning findings may lead a doctor to investigate further.

Anemia and Persistent Fatigue

The bone marrow normally produces red blood cells. When myeloma cells occupy the marrow, normal blood-cell production may be reduced.

This can result in anemia, meaning there are too few healthy red blood cells or too little hemoglobin to carry oxygen efficiently.

Anemia may cause:

• unusual tiredness

• weakness

• shortness of breath, especially with activity

• dizziness

• reduced exercise tolerance

• paleness in some people

Fatigue is not specific to multiple myeloma. It can result from anemia caused by nutritional deficiencies, chronic disease, bleeding, kidney problems and many other conditions.

For this reason, fatigue alone cannot be used to identify myeloma.

A complete blood count can help determine whether anemia or another blood-count abnormality is present.

High Calcium Levels

Bone damage can release calcium into the bloodstream. When the blood calcium level becomes abnormally high, the condition is called hypercalcemia.

Possible symptoms include:

• excessive thirst

• frequent urination

• dehydration

• constipation

• nausea or vomiting

• abdominal discomfort

• weakness

• loss of appetite

• confusion or unusual drowsiness

Significant hypercalcemia can become serious and may affect the kidneys, nervous system, muscles and other organs.

Therefore, symptoms such as severe confusion, marked weakness, repeated vomiting or significant dehydration require medical attention rather than self-treatment.

Kidney Problems

Kidney involvement is an important complication of multiple myeloma.

Abnormal proteins produced by myeloma cells can contribute to kidney damage. High calcium levels and other disease-related mechanisms can also affect kidney function.

Early kidney impairment may produce few obvious symptoms. This is one reason blood and urine testing can be important when myeloma is suspected.

As kidney function worsens, symptoms may include:

• weakness

• tiredness

• swelling of the legs

• shortness of breath from fluid accumulation

• changes related to the buildup of waste products

Kidney problems are not specific to myeloma. Diabetes, high blood pressure, medications, dehydration, infections and many other disorders can affect kidney function.

An abnormal creatinine or other kidney test therefore requires interpretation in context.

Recurrent Infections

Abnormal plasma cells can interfere with normal immune function.

Some people with multiple myeloma become more susceptible to infections, including respiratory infections.

Frequent or unusually severe infections should not automatically be interpreted as cancer. They can have many causes, including other immune disorders, medications and chronic medical conditions.

However, recurrent infections together with abnormal blood counts or other findings may be part of a pattern that prompts additional investigation.

Bruising or Bleeding

Myeloma can sometimes reduce platelet production if the normal bone marrow becomes significantly affected.

Low platelet levels can make bruising or bleeding more likely.

Possible signs include:

• frequent unexplained bruises

• prolonged bleeding from minor injuries

• nosebleeds

• bleeding from the gums

• small red or purple spots caused by bleeding under the skin

These symptoms have many possible causes. They should not be interpreted as evidence of multiple myeloma without appropriate evaluation.

Numbness, Weakness and Spinal Problems

Myeloma can weaken the bones of the spine.

In some cases, a weakened vertebra can collapse and put pressure on nerves or the spinal cord.

This can cause:

• severe or sudden back pain

• numbness

• weakness in the legs

• difficulty walking

• changes in sensation

Sudden severe back pain accompanied by new leg weakness or numbness is an urgent medical problem.

Such symptoms require prompt medical evaluation because spinal cord compression can cause permanent neurological damage if not addressed quickly.

Myeloma can also be associated with peripheral nerve problems in some circumstances, producing tingling, numbness or weakness.

What About Skin Changes?

The previous version of this article presented red spots, dark spots, lip discoloration and itching as typical early signs of multiple myeloma.

That presentation should be removed.

These are not reliable general warning signs of multiple myeloma.

Certain plasma-cell disorders and associated conditions, including some forms of amyloidosis, can produce skin or other tissue changes. But that is different from saying that ordinary rashes or skin discoloration are typical early signs of multiple myeloma.

A persistent rash, itching or skin discoloration should be evaluated according to its own clinical features rather than being assumed to indicate myeloma.

How Is Multiple Myeloma Diagnosed?

Symptoms alone cannot diagnose multiple myeloma.

When a doctor suspects the condition, the evaluation may include several types of tests.

Blood tests

A complete blood count can look for anemia and abnormalities in other blood-cell types.

Blood chemistry testing may evaluate:

• calcium

• creatinine and kidney function

• albumin

• other relevant biochemical measurements

Special protein tests can look for abnormal monoclonal proteins.

These may include:

• serum protein electrophoresis

• immunofixation

• quantitative immunoglobulin testing

• serum free-light-chain testing

The precise combination of tests depends on the clinical situation.

Urine tests

Some myeloma-related proteins or light chains can be detected in urine.

Urine testing can therefore provide additional information when a plasma-cell disorder is suspected.

Imaging

Imaging may be used to identify bone damage or other areas affected by the disease.

Depending on the situation, doctors may use techniques such as:

• CT

• MRI

• PET/CT

• other appropriate skeletal imaging

The purpose is not simply to "look for cancer everywhere." Imaging helps doctors evaluate whether there are bone lesions or other findings relevant to diagnosis and disease assessment.

Bone-marrow examination

A bone-marrow biopsy and aspiration may be needed to determine how many abnormal plasma cells are present and to characterize the disease.

The diagnosis is based on the overall clinical and laboratory picture rather than on one symptom or one blood test.

MGUS, Smoldering Myeloma and Multiple Myeloma Are Not the Same

One important distinction is that not every abnormal plasma-cell finding means active multiple myeloma.

MGUS

Monoclonal gammopathy of undetermined significance (MGUS) involves an abnormal monoclonal protein but does not meet the criteria for multiple myeloma or another related cancer.

MGUS is not itself multiple myeloma, although some people with MGUS can later develop a related disorder.

Smoldering multiple myeloma

Smoldering multiple myeloma is an asymptomatic plasma-cell condition with greater abnormalities than MGUS but without the findings that define active myeloma requiring treatment.

People with smoldering disease may be monitored closely rather than immediately receiving treatment, depending on their individual circumstances.

Active multiple myeloma

Active multiple myeloma involves evidence that the abnormal plasma-cell disorder is causing significant disease or has reached established diagnostic thresholds associated with organ damage or a high risk of imminent organ damage.

This distinction is important because an abnormal protein on a blood test does not automatically mean that a person has active cancer.

Who Is at Higher Risk?

Multiple myeloma becomes more common with increasing age.

Certain factors have been associated with a higher risk, including:

• older age

• male sex

• a personal history of MGUS or certain other plasma-cell disorders

• some patterns of family history

• certain previous exposures

The exact cause of most cases remains unknown.

Having a risk factor does not mean that someone will develop multiple myeloma.

Can Multiple Myeloma Be Prevented or Screened For?

There is no established lifestyle method that can reliably prevent most cases of multiple myeloma.

It is therefore misleading to suggest that a particular food, supplement, detox program or routine health practice can prevent the disease.

There are also no recommended routine screening tests for multiple myeloma in most people who have no symptoms. The disease can sometimes be discovered incidentally when blood tests performed for another reason show an abnormal protein or other finding.

People who already have conditions such as MGUS may undergo periodic monitoring because their risk is different from that of the general population.

When Should Someone Seek Medical Evaluation?

A single symptom rarely identifies multiple myeloma.

Medical evaluation is more appropriate when symptoms are persistent, unexplained, worsening or occur in combination.

Examples include:

• persistent unexplained bone pain

• repeated fractures

• unexplained anemia or persistent fatigue

• recurrent or unusually severe infections

• unexplained abnormal calcium levels

• unexplained kidney-function abnormalities

• persistent weakness

• unexplained bruising or bleeding

• a blood or urine test showing an abnormal monoclonal protein

The appropriate next step is not to assume that these findings mean cancer. A healthcare professional can determine whether additional testing is justified.

When Is Urgent Care Appropriate?

Some complications require prompt attention regardless of their underlying cause.

Seek urgent medical care for symptoms such as:

• sudden severe back pain with leg weakness or numbness

• new difficulty walking associated with neurological symptoms

• severe confusion

• marked weakness with severe thirst or dehydration

• significant breathing difficulty

• serious or uncontrolled bleeding

These symptoms can have causes other than multiple myeloma, but they should not be ignored.

The Main Point About Multiple Myeloma Symptoms

Multiple myeloma is best understood as a disease of abnormal plasma cells that can affect several systems because those cells accumulate in bone marrow, alter bone metabolism, interfere with normal blood-cell production and produce abnormal proteins.

The most important symptoms and complications include bone problems, anemia, recurrent infections, high calcium, kidney impairment and certain neurological problems.

But none of these findings, by itself, proves that someone has multiple myeloma.

The diagnosis requires an appropriate combination of clinical assessment, blood and urine testing, imaging and, when indicated, examination of the bone marrow.

Key Takeaways

• Multiple myeloma is a cancer of abnormal plasma cells, not a disease of the blood vessels.

• The term "cancer without joints" is not a recognized medical name for multiple myeloma.

• Bone pain, especially persistent pain in the back or other bones, can occur because myeloma can weaken bone.

• Anemia can cause fatigue, weakness and shortness of breath.

• Myeloma can sometimes cause high blood calcium and kidney problems.

• Recurrent infections can occur because normal immune function may be affected.

• Sudden back pain with new weakness or numbness requires urgent medical evaluation.

• Skin rashes and discoloration should not automatically be interpreted as signs of myeloma.

• Symptoms alone cannot diagnose the disease.

• Doctors may use blood tests, urine tests, imaging and bone-marrow examination to investigate suspected myeloma.

• MGUS, smoldering myeloma and active multiple myeloma are different conditions.

• There is no established food, supplement or "detox" approach that prevents multiple myeloma.

• Routine screening is not recommended for most asymptomatic people.

How to Protect Bone Health: Nutrition, Exercise & Risk

 How to Protect Bone Health: Nutrition, Exercise and Osteoporosis Risk

Bone health is often reduced to one simple message: eat enough calcium.

Calcium is important, but that explanation leaves out much of what determines whether an older adult can maintain strong bones and avoid a fracture.

Bones are living tissue. They continually undergo remodeling, while muscles, balance, hormones, nutrition, medications and medical conditions all influence how the skeleton changes over time. Physical activity also matters because bones respond to mechanical loading, while stronger muscles and better balance can help reduce falls.

A useful bone-health strategy therefore has several parts rather than one “bone-strengthening” food or supplement.

The practical question is not simply “How can I make my bones stronger?” It is:

Am I giving my bones and muscles the nutrition, physical activity and protection they need—and do I have any risk factors that require medical assessment?

Why bone health changes with age

Bone is not an inert material. The skeleton is continuously remodeled as older bone is removed and new bone is formed.

During childhood and adolescence, bone formation is especially important because the skeleton is growing and building bone mass. By early adulthood, most people have reached their peak bone mass.

Later in life, the balance between bone formation and breakdown can change. The rate of bone loss varies considerably between individuals.

Age is only one factor.

Genetics, hormonal changes, physical activity, nutrition, smoking, alcohol use, body weight, certain medicines and several medical conditions can influence bone density and fracture risk.

This explains why two people of the same age can have very different bone health.

For many women, the menopause transition is particularly important because declining estrogen can accelerate bone loss. Men can also develop osteoporosis, particularly with advancing age or certain medical conditions and medications.

The goal, therefore, is not to prevent every change associated with aging. It is to identify the factors that can be improved and recognize situations in which medical evaluation is warranted.

Start with nutrition, but don't reduce bone health to one nutrient

Bones require minerals and a protein-based framework, but the body needs an overall adequate diet rather than a single “superfood.”

Calcium

Calcium is a major mineral component of bone. The body cannot manufacture calcium, so it must come from food or, when appropriate, supplements.

NIH guidance gives different calcium requirements according to age and sex. For example, adults aged 19–50 generally need 1,000 mg per day; women over 50 and adults over 70 need 1,200 mg per day under the U.S. reference values. Individual nutritional requirements can vary, and local dietary guidance may differ.

Food is often a practical way to obtain calcium.

Sources can include:

• Milk, yogurt and cheese

• Calcium-set tofu

• Calcium-fortified plant beverages

• Some leafy green vegetables

• Small fish eaten with their bones

• Other calcium-fortified foods

The important point is not to identify one “best” calcium food. It is to build a diet that provides enough calcium consistently.

Vitamin D

Vitamin D helps the body absorb calcium and contributes to normal bone and muscle function.

NIH lists 600 IU (15 micrograms) per day for most adults through age 70 and 800 IU (20 micrograms) for adults over 70 as its general recommended intake values. Individual needs can differ, particularly when deficiency or a medical condition is present.

Sunlight can contribute to vitamin D production, but deliberately seeking prolonged unprotected sun exposure is not a universal solution. Vitamin D production varies with factors such as skin pigmentation, age, season, latitude, clothing and sunscreen use.

If deficiency is suspected, a healthcare professional can determine whether dietary changes, testing or supplementation is appropriate.

Protein

Protein is sometimes overlooked in discussions about osteoporosis.

Bone contains a protein-based structural framework, while adequate protein is also important for maintaining muscle. Muscle strength becomes increasingly relevant with age because weakness can contribute to reduced mobility and falls.

Useful protein sources include:

• Eggs

• Dairy foods

• Fish

• Lean meat and poultry

• Beans and lentils

• Soy foods

• Nuts and seeds

People with kidney disease or other conditions that affect protein requirements should obtain individualized dietary advice rather than simply increasing protein intake.

What about magnesium, vitamin K and other nutrients?

A varied diet supplies many nutrients involved in normal body function and bone metabolism.

However, this does not mean that everyone should take a collection of bone-health supplements.

There is an important difference between:

“This nutrient participates in normal physiology”

and

“Taking extra amounts of this nutrient prevents osteoporosis.”

The first statement may be well established while the second may not be.

That distinction helps prevent a common mistake: turning a nutritious food or nutrient into a treatment claim.

Exercise affects both bones and the muscles that protect them

Exercise is one of the most useful non-drug components of a bone-health strategy.

But different forms of exercise serve different purposes.

Weight-bearing activity

Weight-bearing activities place mechanical forces through the skeleton.

Depending on age, fitness and health status, examples can include:

• Brisk walking

• Stair climbing

• Dancing

• Hiking

• Jogging

• Some recreational sports

The appropriate intensity depends on the individual.

Walking can be valuable, particularly for people who are currently inactive, but walking should not automatically be presented as the complete exercise program for someone concerned about osteoporosis.

Resistance training

Resistance exercise challenges muscles against an external load.

Examples include:

• Resistance bands

• Free weights

• Weight machines

• Appropriately selected body-weight exercises

Resistance training can help maintain or improve muscle strength and also provides mechanical loading to the skeleton.

This becomes particularly useful as people age because maintaining strength can make everyday movement easier and may contribute to fall prevention. NIAMS recommends combining weight-bearing, resistance and balance activities rather than relying on one form of exercise alone.

Balance training

A strong skeleton cannot completely protect someone from a fracture if a fall occurs.

Balance training can therefore be an important part of bone-fracture prevention, especially for older adults.

Appropriate activities may include:

• Tai chi

• Supported balance exercises

• Controlled step exercises

• Functional strength and balance practice

Exercises should be performed in a safe environment, with support when necessary.

If you already have osteoporosis, don't copy a generic exercise routine

Exercise remains valuable after osteoporosis is diagnosed, but the program may need modification.

Someone with low bone density is not automatically in the same situation as someone who has already experienced vertebral or hip fractures.

A person with osteoporosis, previous fragility fractures, significant balance problems or other skeletal limitations may benefit from an individualized exercise plan developed with a healthcare professional or appropriately qualified exercise specialist.

Some movements that are reasonable for a healthy adult may require modification for someone with particular fracture risks.

The correct message is therefore not:

“Avoid exercise if your bones are weak.”

It is:

“Use the right exercise for your condition and level of fracture risk.”

NIAMS specifically recommends professional guidance when osteoporosis or other physical limitations affect exercise choices.

The risk factors that food cannot fix

A nutritious diet cannot eliminate every cause of osteoporosis.

Some important risk factors include:

Age and hormonal changes

Bone loss generally becomes more important with aging. Menopause can accelerate bone loss in women, while hormonal problems can also affect bone health in both sexes.

Smoking

Smoking is associated with poorer bone health and increased fracture risk. Avoiding tobacco is therefore relevant not only to heart and lung health but also to the skeleton.

Heavy alcohol use

Chronic heavy alcohol consumption is associated with increased osteoporosis and fracture risk.

Low body weight and inadequate nutrition

Being underweight and chronically consuming too little energy or protein can contribute to poor skeletal health.

Extreme dieting is therefore not a sensible strategy for long-term health.

Medicines

Some medicines can increase bone loss or fracture risk.

Long-term glucocorticoid use is a particularly important example. Other medicines may also influence bone or fall risk depending on the drug and the individual.

Do not stop a prescribed medicine because you are worried about osteoporosis.

Instead, ask your doctor or pharmacist:

• Does this medicine affect bone health?

• Does the dose or duration increase my risk?

• Do I need monitoring?

• Are there preventive measures I should consider?

Medical conditions

Certain endocrine, gastrointestinal, kidney, inflammatory and other conditions can affect bone metabolism, nutrient absorption or fracture risk.

This is one reason why a person with apparently good nutrition can still develop osteoporosis.

Don't let “bone-strengthening foods” distract from the bigger picture

Many foods contain nutrients relevant to bone health.

That does not mean one food prevents osteoporosis.

Sesame seeds, leafy vegetables, dairy foods, tofu, nuts, seeds, fish and legumes can all fit into a nutritious diet. But none should be promoted as a standalone treatment for osteoporosis.

The same principle applies to products marketed as:

• Bone-strengthening powders

• Herbal bone formulas

• Calcium drinks

• “Natural osteoporosis remedies”

• High-dose vitamin combinations

A supplement can be appropriate in a particular situation, but “natural” does not automatically mean effective or risk-free.

NCCIH notes that dietary and herbal supplements vary substantially in the amount of scientific evidence available and can interact with medicines or pose risks in certain medical conditions.

If someone has diagnosed osteoporosis, supplements should not be presented as substitutes for evidence-based medical treatment.

More calcium is not automatically better

One of the most persistent bone-health misunderstandings is that if calcium is good, taking large amounts must be better.

That does not follow.

NIH identifies upper intake limits for calcium because excessive intake can cause adverse effects. For adults, the upper limit is 2,500 mg per day for ages 19–50 and 2,000 mg per day for adults over 50, counting food, beverages and supplements together.

Supplementation also deserves special attention because calcium can interact with certain medicines, including levothyroxine and some antibiotics.

Anyone with kidney disease, a history of kidney stones, conditions affecting calcium metabolism, or regular medication use should discuss supplementation with a healthcare professional rather than choosing a high-dose product independently.

Osteoporosis can be present without obvious symptoms

Osteoporosis often develops silently.

A person may feel completely normal until a fracture occurs.

Possible warning signs include:

• A fracture after a relatively minor fall or injury

• Unexplained loss of height

• A stooped posture

• Sudden or persistent back pain, particularly following minor trauma

• Repeated fractures

These findings do not prove osteoporosis. Back pain, for example, has many possible causes.

But a low-trauma fracture or other concerning change deserves medical assessment rather than being dismissed as “normal aging.”

When is a bone-density test useful?

A bone mineral density test, usually performed using DXA, measures the mineral density of specific bones, commonly the hip and spine.

DXA can help diagnose osteoporosis, identify low bone density and contribute to fracture-risk assessment. It can also be used to monitor osteoporosis treatment.

Not everyone needs a DXA scan at the same age.

Whether testing is appropriate depends on factors such as:

• Age

• Sex and menopausal status

• Previous fractures

• Medication exposure

• Medical conditions

• Other osteoporosis risk factors

Screening recommendations vary between countries and professional organizations.

For example, the U.S. Preventive Services Task Force recommends screening women aged 65 years or older and recommends risk assessment to determine whether screening is appropriate for postmenopausal women younger than 65 who are at increased risk. Local recommendations may differ.

A healthcare professional can interpret your individual risk rather than relying on age alone.

Bone density is important, but fracture risk is the outcome that matters

A person may focus entirely on a DXA number, but bone health is more complicated than one measurement.

Fracture risk is influenced by bone density as well as age, previous fractures, medications, falls, medical conditions and other factors.

That is why two people with similar bone-density measurements may not have identical clinical risk.

This also explains why “raising bone density” should not become the only goal.

Maintaining muscle, improving balance, preventing falls, eating adequately and treating osteoporosis when necessary are all part of reducing the chance of a serious fracture.

A practical bone-health plan

A useful long-term approach can be divided into four areas.

1. Build a reliable nutrition foundation

Regularly eat a varied diet containing appropriate sources of:

• Calcium

• Protein

• Vitamin D

• Fruits and vegetables

• Whole grains and legumes

• Other nutrients supplied by a balanced diet

Do not rely on one food.

2. Keep the skeleton and muscles active

Aim for regular physical activity appropriate to your age and health.

Where suitable, combine:

• Weight-bearing activity

• Resistance training

• Balance exercises

Adults are generally advised to accumulate at least 150 minutes of moderate-intensity aerobic activity per week, or an equivalent amount of vigorous activity, alongside muscle-strengthening activity on at least two days per week. Individual limitations may require a modified plan.

3. Reduce avoidable risks

Do not smoke.

Avoid heavy alcohol use.

Avoid prolonged inactivity.

Maintain adequate nutrition rather than repeated extreme dieting.

Review long-term medicines with a healthcare professional when appropriate.

4. Know when lifestyle advice is not enough

Seek professional assessment if you have:

• A fracture after a minor injury

• Significant or unexplained height loss

• Persistent back pain after minor trauma

• A history of osteoporosis

• Long-term exposure to medicines associated with bone loss

• A medical condition associated with osteoporosis

• Multiple risk factors for fracture

• Concerns about whether you need bone-density testing

Questions worth asking a healthcare professional

A medical appointment becomes more useful when the questions are specific.

Consider asking:

“Do I have risk factors for osteoporosis?”

“Do my medicines affect my bones or my risk of falling?”

“Should I have a bone-density test?”

“Am I getting enough calcium and vitamin D from my diet?”

“Would resistance or weight-bearing exercise be appropriate for me?”

“Do I need an exercise program adapted to my fracture risk?”

“If I have had a low-trauma fracture, should I be evaluated for osteoporosis?”

These questions are more useful than simply asking which supplement is “best for bones.”

Key Takeaways

• Bone health depends on more than calcium.

• Adequate nutrition, physical activity, muscle strength and fall prevention work together.

• Calcium and vitamin D are important, but taking more than needed does not automatically provide greater protection.

• Protein supports the structural framework of bone and helps maintain muscle.

• Weight-bearing and resistance exercises provide different but complementary benefits.

• Balance becomes increasingly important because preventing falls can help prevent fractures.

• Smoking, heavy alcohol use, low body weight, certain medicines and medical conditions can increase fracture risk.

• Osteoporosis can exist without obvious symptoms.

• A fracture after a relatively minor injury can be an important reason to seek assessment.

• DXA is an important tool for measuring bone density, but fracture risk involves more than one test result.

• Food and supplements should not be presented as substitutes for medical treatment when osteoporosis requires treatment.

• The most useful bone-health strategy is a combination of adequate nutrition, appropriate exercise, risk-factor management and timely medical evaluation.
