Osteoporosis is a common bone disease that causes bones to become weak, thin and more likely to break. Unlike many health conditions that produce noticeable warning signs, osteoporosis can develop quietly for years. In some people, the first indication that something is wrong is a broken bone after a minor fall, bump or even an ordinary movement.
The condition can affect both women and men, although the risk generally increases with age. The hip, spine and wrist are among the bones most commonly affected by osteoporosis. A fracture in these areas can lead to pain, reduced movement, loss of independence and other complications, particularly in older adults.
The good news is that bone health can be protected at every stage of life. A balanced diet, regular physical activity, adequate calcium and vitamin D, avoiding smoking, limiting excessive alcohol consumption and reducing the risk of falls can all contribute to healthier bones. For people who already have osteoporosis, healthcare professionals may also recommend medicines designed to slow bone loss or reduce the risk of fractures.
WHAT IS OSTEOPOROSIS?
Osteoporosis literally means porous or weakened bone. Healthy bones are living tissues that are constantly being broken down and replaced. This natural process helps maintain the strength and structure of the skeleton.
As osteoporosis develops, bone is lost faster than the body can replace it. The internal structure of the bone becomes less dense, the spaces within the bone become larger and the outer layer may become thinner. As a result, the bone becomes weaker and can fracture more easily.
A person can have osteoporosis without feeling sick or experiencing obvious symptoms. This is why osteoporosis is often described as a "silent disease." In many cases, it is discovered only after a fracture occurs.
Osteoporosis should not be considered only a disease affecting elderly women. Men can also develop osteoporosis, and younger people may be at increased risk because of certain medical conditions, medicines, nutritional problems or hormonal changes.
WHAT CAUSES OSTEOPOROSIS?
There is not always one single cause of osteoporosis. Bone loss usually develops because of a combination of ageing, genetics, hormonal changes, nutrition, lifestyle factors, medical conditions and certain medicines.
As people grow older, bone formation generally becomes slower while bone loss can increase. This gradually reduces bone strength.
In women, the decline in estrogen around and after menopause can accelerate bone loss. Men can also experience bone loss as they age, particularly when other risk factors are present. Low testosterone caused by certain medical conditions may also contribute to osteoporosis in men.
A diet that does not provide enough calcium, vitamin D or protein can also contribute to poor bone health. Calcium is an important structural component of bone, while vitamin D helps the body absorb calcium. Protein is also important for maintaining muscles and overall skeletal health.
Lack of physical activity is another important factor. Bones respond to physical stress and movement. Regular weight-bearing and resistance activities help maintain bone strength and muscle function.
Smoking and heavy alcohol consumption can also increase the risk of osteoporosis and fractures.
Some medical conditions can increase the risk as well. These include certain endocrine and hormonal disorders, gastrointestinal conditions that interfere with nutrient absorption, rheumatoid arthritis, some cancers and other chronic diseases.
Long-term use of certain medicines can also affect bone health. Examples include glucocorticoid corticosteroids and some medicines used for seizures, cancer and other chronic conditions. People taking these medicines should not stop them on their own. Instead, they should discuss their bone-health risk with their healthcare professional.
WHO IS AT RISK OF OSTEOPOROSIS?
Several factors can increase a person's likelihood of developing osteoporosis.
Age is one of the major risk factors because bone loss generally becomes more significant as people get older.
Women, particularly after menopause, have an increased risk because of hormonal changes and generally lower peak bone mass compared with men. However, men are also affected, especially at older ages.
A family history of osteoporosis or hip fracture may increase risk. A previous fracture occurring after a relatively minor injury can also be an important warning sign.
People who are underweight or have a low body mass may have a higher risk because they have less bone mass to lose.
Other risk factors include physical inactivity, smoking, heavy alcohol use, inadequate calcium or vitamin D intake, certain hormonal disorders and prolonged periods of inactivity or bed rest.
People who take certain medicines for a long period should also discuss osteoporosis risk with their healthcare provider.
Having one risk factor does not automatically mean that a person has osteoporosis. It simply means that additional attention to bone health may be appropriate.
SYMPTOMS OF OSTEOPOROSIS
One of the most important things to understand about osteoporosis is that it often causes no symptoms in its early stages.
A person may have significant bone loss while continuing normal daily activities without pain or obvious physical changes. This is why waiting for symptoms before paying attention to bone health can be risky.
When osteoporosis becomes advanced or causes a fracture, symptoms may include:
Persistent or sudden back pain.
A broken hip, wrist or other bone following a minor fall or injury.
Loss of height over time.
A stooped or hunched posture.
Pain following ordinary movements such as bending, lifting or turning.
Difficulty moving after a fracture.
In severe osteoporosis, bones may become fragile enough to fracture following relatively minor trauma. Vertebral fractures in the spine can sometimes occur without a major accident and may result in back pain, reduced height or changes in posture.
If someone experiences a fracture after a simple fall or relatively minor injury, it is worth discussing bone health with a healthcare professional rather than assuming it was simply an unfortunate accident.
OSTEOPOROSIS AND OSTEOPENIA: WHAT IS THE DIFFERENCE?
Osteopenia and osteoporosis are related but they are not exactly the same.
Osteopenia means that bone density is lower than normal but has not reached the level used to define osteoporosis. It can be considered a warning sign that a person may have an increased risk of developing osteoporosis and fractures.
Osteoporosis represents more significant loss of bone density and strength and carries a greater risk of fractures.
A healthcare professional can use a bone mineral density test to assess bone health and determine whether bone density falls within the normal range, osteopenia range or osteoporosis range.
HOW IS OSTEOPOROSIS DIAGNOSED?
Because osteoporosis often has no obvious symptoms, testing can be important for people who are at increased risk.
One of the main tests used to assess bone mineral density is a DEXA or DXA scan. DEXA stands for dual-energy X-ray absorptiometry. The test commonly measures bone density at the hip and spine.
A DEXA scan is quick, painless and uses a very low level of X-ray radiation. It can help healthcare professionals determine whether a person has osteoporosis or low bone density and can also be used to monitor changes over time.
A healthcare professional may also consider a person's age, medical history, family history, previous fractures, medicines, lifestyle and other risk factors.
For example, a person with a history of fractures, long-term corticosteroid use or certain medical conditions may require closer assessment even if they do not have obvious symptoms.
Screening recommendations vary according to age, sex and individual risk factors. In the United States, for example, routine screening is recommended for women aged 65 and older, while younger women with increased risk may also require assessment.
People should speak with a healthcare professional about whether bone-density testing is appropriate for them rather than relying on age alone.
TREATMENT OF OSTEOPOROSIS
The main goals of osteoporosis treatment are to strengthen or preserve bone, slow further bone loss and, most importantly, reduce the risk of fractures.
Treatment depends on the person's age, sex, bone density, fracture history, general health, other medical conditions and risk of future fractures.
Lifestyle measures are an important part of treatment. However, people with established osteoporosis may also need prescription medicines.
CALCIUM, VITAMIN D AND HEALTHY NUTRITION
Good nutrition supports both bone and muscle health.
Calcium is essential for maintaining bones. Good dietary sources include dairy products, some leafy green vegetables, sardines and other fish eaten with their bones, tofu and calcium-fortified foods.
Vitamin D helps the body absorb calcium. It can be obtained through certain foods, supplements when necessary and exposure to sunlight, although the amount of vitamin D a person obtains from sunlight can vary depending on several factors.
A balanced diet should also contain adequate protein, vegetables, fruits and other essential nutrients.
Calcium or vitamin D supplements should not automatically be taken in large amounts. The appropriate amount depends on age, diet, health status and individual needs. A doctor or pharmacist can help determine whether supplementation is appropriate.
EXERCISE FOR STRONGER BONES
Physical activity plays an important role in maintaining bone and muscle strength.
Weight-bearing activities such as walking can support bone health. Resistance or strength exercises can help strengthen muscles and support better balance and physical function. Exercise can also help reduce the risk of falls, which is particularly important for people whose bones are already weak.
However, someone who already has osteoporosis should not suddenly begin intense exercise without professional guidance. Certain high-impact activities or movements involving excessive bending or twisting may increase injury risk in people with fragile bones.
A doctor, physiotherapist or qualified exercise professional can help develop a safe exercise programme based on the person's condition.
MEDICINES USED TO TREAT OSTEOPOROSIS
Some people with osteoporosis require medication to reduce their risk of fractures.
Bisphosphonates are among the medicines used to slow bone loss and preserve bone strength. Other treatment options include certain RANK ligand inhibitors, selective estrogen receptor modulators, hormone-related treatments in selected circumstances, parathyroid hormone-related medicines and sclerostin inhibitors.
The appropriate medicine depends on the individual. There is no single osteoporosis medicine that is suitable for everyone.
Some medicines have important precautions and possible side effects, so treatment should be selected and monitored by a qualified healthcare professional.
People should also continue appropriate nutrition, physical activity and fall-prevention measures while taking osteoporosis medication.
HOW TO PREVENT OSTEOPOROSIS
Prevention starts long before osteoporosis develops.
Building strong bones during childhood and young adulthood is important because the body establishes much of its peak bone mass during these years. However, bone health remains important throughout adulthood and older age.
Eating a nutritious diet containing adequate calcium, vitamin D and protein is one of the foundations of healthy bones.
Regular physical activity is another important step. Walking, strength training and other suitable weight-bearing activities can help maintain bone and muscle health.
Avoiding cigarettes and tobacco products is also important. Smoking is associated with reduced bone density and an increased risk of fractures.
Alcohol should be consumed responsibly because heavy alcohol use can weaken bones and increase the risk of falls.
Maintaining a healthy body weight, staying physically active and managing medical conditions that can affect bone health are also useful preventive measures.
PREVENTING FALLS WHEN YOU HAVE WEAK BONES
For someone with osteoporosis, preventing falls is just as important as maintaining bone strength.
A fall that might cause only a minor injury in a person with strong bones can result in a serious fracture in someone with osteoporosis.
Simple changes around the home can help. Keep walkways clear, improve lighting, use handrails where necessary and be especially careful around stairs and slippery surfaces.
People with balance problems may benefit from appropriate walking aids after professional assessment. Good footwear can also provide greater stability.
Regular exercises that improve strength and balance can reduce the risk of falling. Vision problems and medicines that cause dizziness or drowsiness should also be discussed with a healthcare professional.
OSTEOPOROSIS IN WOMEN
Women have a particularly high risk of osteoporosis after menopause because estrogen levels decline.
Bone loss can become faster around menopause and may continue gradually afterward.
Women with additional risk factors, such as a family history of osteoporosis, previous fractures, low body weight or long-term use of certain medicines, should discuss their bone health with a healthcare professional.
Hormone therapy may be appropriate for some women in certain circumstances, but it is not suitable for everyone. Its potential benefits and risks should be discussed individually with a qualified healthcare professional.
OSTEOPOROSIS IN MEN
Osteoporosis can affect men too.
Because osteoporosis is often associated with women, some men may overlook their own risk. Older men, men with certain hormonal problems, men with a history of fractures and men taking medicines that can weaken bones may need assessment.
The general approach to treatment includes nutrition, physical activity, fall prevention, management of underlying medical conditions and medicines when clinically indicated.
WHEN SHOULD YOU SEE A DOCTOR?
You should consider speaking with a healthcare professional if you have experienced a fracture after a minor fall or injury, have lost noticeable height, developed persistent unexplained back pain or have several risk factors for osteoporosis.
People taking long-term corticosteroids or other medicines associated with bone loss should also ask their healthcare professional whether their bone health needs to be monitored.
Do not wait until a major fracture occurs before discussing osteoporosis if you have significant risk factors.
COMMON QUESTIONS ABOUT OSTEOPOROSIS
CAN OSTEOPOROSIS BE CURED?
Osteoporosis is a chronic condition, but it can often be managed. Treatment can slow bone loss, improve or maintain bone strength and reduce the risk of fractures. The appropriate treatment depends on the individual's condition.
CAN YOUNG PEOPLE GET OSTEOPOROSIS?
Yes. Although osteoporosis becomes more common with age, younger people can develop bone loss because of certain medical conditions, nutritional problems, hormonal disorders or medicines. Rare forms of osteoporosis can also occur in children and teenagers.
DOES OSTEOPOROSIS CAUSE PAIN?
Osteoporosis itself often causes no pain. Pain may occur when weakened bones fracture, particularly in the spine, hip or other vulnerable areas.
IS MILK ENOUGH TO PREVENT OSTEOPOROSIS?
Milk can provide calcium and other nutrients important for bone health, but bone protection involves more than one food. A balanced diet, adequate vitamin D, physical activity, healthy lifestyle habits and appropriate medical care all play a role.
CAN WALKING HELP OSTEOPOROSIS?
Walking is a weight-bearing activity that can contribute to bone and overall physical health. Strength and balance exercises may also be useful. People with established osteoporosis should choose activities appropriate for their condition and seek professional advice before starting strenuous exercise.
IS OSTEOPOROSIS ONLY A WOMAN'S DISEASE?
No. Both women and men can develop osteoporosis. The risk is particularly high in women after menopause, but older men and men with certain medical conditions or risk factors can also develop the disease.
FINAL THOUGHTS
Osteoporosis can develop quietly, but its consequences can be serious. The disease weakens bones and increases the likelihood of fractures, particularly in the hip, spine and wrist.
The most important message is that bone health should not be ignored simply because there are no symptoms. Eating a nutritious diet, getting adequate calcium and vitamin D, staying physically active, avoiding smoking, limiting excessive alcohol consumption and preventing falls can all contribute to stronger bones.
People who have risk factors for osteoporosis should speak with a healthcare professional about whether they need bone-density testing or other evaluation. For people who already have osteoporosis, appropriate treatment can help reduce the risk of future fractures.
Taking care of your bones is not something that begins only in old age. It is a lifelong health investment that starts with the habits you develop today.
