Osteoporosis: Causes, Symptoms, Diagnosis, Treatment and Prevention
Osteoporosis is a condition that weakens bones and increases the risk of fractures. Learn about osteoporosis causes, symptoms, risk factors, DXA diagnosis, T-scores, treatment options, medicines and ways to prevent osteoporotic fractures.
Osteoporosis is a common bone condition that gradually makes bones weaker and more fragile. Because the disease often develops without noticeable symptoms, many people do not realise that they have osteoporosis until they suffer a fracture.
Bones remain living tissues throughout life. Your body continuously removes old bone and replaces it with new bone. When bone loss begins to outpace bone formation, bone density and strength can decline. Over time, this process can increase the risk of fractures, particularly in the hip, spine and wrist.
Although ageing increases the risk of osteoporosis, the condition does not affect everyone in the same way. Menopause, family history, low body weight, physical inactivity, smoking, excessive alcohol consumption, certain medical conditions and long-term use of medicines such as corticosteroids can also increase the risk.
At Jyoti Hospital, Gurugram, our orthopaedic team evaluates patients with osteoporosis risk factors, unexplained fractures and bone-health concerns. Early assessment can help identify bone loss and allow patients to take appropriate steps to reduce their future fracture risk.
What Is Osteoporosis?
Osteoporosis is a bone disease in which bone mineral density and bone strength decrease, making bones more likely to break.
Healthy bones contain a strong internal structure that allows them to withstand everyday stresses. Osteoporosis changes this structure and reduces bone strength.
The disease often develops silently. You may not experience pain or other obvious symptoms while bone density is decreasing. In some people, the first sign appears when they suffer a fracture after a relatively minor fall or injury.
Osteoporosis can affect anyone, although the risk increases with age and certain hormonal, medical and lifestyle factors.
What Happens to Bones in Osteoporosis?
Your bones constantly undergo a natural process called bone remodelling.
During this process, specialised cells remove older bone while other cells form new bone.
When these two processes remain reasonably balanced, your bones maintain their strength. However, several factors can cause bone breakdown to exceed bone formation.
As a result:
- Bone mineral density decreases.
- The internal structure of bone becomes weaker.
- Bones become more fragile.
- The risk of fractures increases.
Women can experience faster bone loss around menopause because declining oestrogen levels affect bone metabolism.
Men generally lose bone more gradually, although age, hormonal changes, medical conditions, medications and lifestyle factors can also contribute to osteoporosis.
Osteoporosis vs Osteopenia: What Is the Difference?
Osteopenia means that bone mineral density is lower than normal but does not meet the usual bone-density threshold for osteoporosis.
It does not mean that you will definitely develop osteoporosis. However, osteopenia can indicate an increased risk of future bone loss and fractures.
Our doctors interpret bone density together with other factors such as age, sex, previous fractures and other clinical risk factors.
A person with osteopenia may therefore need lifestyle changes and monitoring, while someone with osteoporosis or a high fracture risk may require medical treatment.
What Causes Osteoporosis?
Osteoporosis can develop because of the natural ageing process, hormonal changes or a combination of genetic, lifestyle and medical factors.
Common contributors include:
Ageing
Bone loss generally increases with age. As you get older, the body may not replace bone as quickly as it removes it.
Menopause
Declining oestrogen levels around menopause can accelerate bone loss in women.
Family History
A family history of osteoporosis or hip fracture can increase your risk.
Low Physical Activity
Bones respond to mechanical loading. Prolonged inactivity can contribute to loss of bone and muscle strength.
Poor Nutrition
Inadequate calcium, vitamin D, protein and overall nutritional intake can affect bone health.
Smoking
Smoking can negatively affect bone health and increase overall fracture risk.
Excessive Alcohol Consumption
Heavy alcohol consumption can contribute to poor bone health and increase the risk of falls.
Certain Medical Conditions
Several medical conditions can increase bone loss or interfere with normal bone metabolism.
Long-Term Medication Use
Some medicines, particularly prolonged corticosteroid therapy, can accelerate bone loss.
Our doctors therefore consider both primary osteoporosis, which develops mainly with ageing and hormonal changes, and secondary osteoporosis, which results from another medical condition or medication.
What Are the Risk Factors for Osteoporosis?
You may have a higher risk of osteoporosis if you have one or more of the following:
- Increasing age
- Postmenopausal status
- Early or premature menopause
- Previous fragility fracture
- Family history of osteoporosis or hip fracture
- Low body weight
- Physical inactivity
- Smoking
- Excessive alcohol consumption
- Low calcium or vitamin D intake
- Long-term corticosteroid use
- Certain thyroid or parathyroid disorders
- Certain gastrointestinal conditions that affect nutrient absorption
- Chronic kidney or liver disease
- Certain hormonal disorders
- Some medications that affect bone density or increase fall risk
Having a risk factor does not automatically mean that you have osteoporosis. However, it can help your doctor decide whether you need further assessment.
What Are the Symptoms of Osteoporosis?
Osteoporosis usually does not cause symptoms in its early stages.
That makes the condition difficult to recognise without appropriate assessment.
Many people discover that they have osteoporosis only after they experience a fracture.
When osteoporosis causes vertebral fractures, you may develop:
- Persistent or sudden back pain
- Loss of height
- A stooped or hunched posture
- Reduced mobility
- Recurrent spinal fractures
Bones affected by osteoporosis can become so fragile that fractures occur after relatively minor trauma or even during normal activities in severe cases.
At Jyoti Hospital, we encourage patients to seek evaluation after an unexpected fracture rather than assuming that the injury occurred only because of a fall.
What Are Fragility Fractures?
A fragility fracture occurs when a bone breaks after relatively low-energy trauma that would not normally fracture healthy bone.
For example, a fracture after a fall from standing height can sometimes indicate underlying bone weakness.
Fragility fractures deserve particular attention because they can indicate an increased risk of future fractures.
A patient who develops one fragility fracture may require an assessment of overall bone health and fracture risk.
Which Bones Commonly Fracture Because of Osteoporosis?
Osteoporosis can affect many bones, but fractures commonly occur in:
Hip
Hip fractures can significantly affect mobility and independence, particularly in older adults.
They may require surgery followed by rehabilitation and careful management of underlying osteoporosis.
Spine
Osteoporotic vertebral fractures can occur with relatively minor trauma.
They may cause:
- Back pain
- Loss of height
- Spinal curvature
- Reduced mobility
Some vertebral fractures may cause few symptoms and remain undiagnosed.
Wrist
A fall onto an outstretched hand can cause a wrist fracture. In an older adult, such a fracture may indicate underlying bone weakness.
Upper Arm and Shoulder
Osteoporosis can also contribute to fractures around the upper arm and shoulder, particularly after falls.
A fracture in any of these locations does not automatically prove that you have osteoporosis. However, certain fractures should prompt doctors to consider a bone-health assessment.
How Is Osteoporosis Diagnosed?
Our doctors do not diagnose osteoporosis based on symptoms alone.
The evaluation usually combines:
- Medical history
- Fracture history
- Family history
- Physical examination
- Medication review
- Assessment of lifestyle and risk factors
- Bone mineral density testing when indicated
- Additional investigations when necessary
Our doctor may ask about previous fractures, menopause, diet, exercise, smoking, alcohol use and medicines that can affect bone health. Physical assessment may also include checking height, posture, balance, gait and muscle strength.
At Jyoti Hospital, our orthopaedic team can use this information to determine whether you require bone-density testing or further evaluation.
What Is a DXA or DEXA Scan?
A DXA scan, also commonly written as DEXA scan, measures bone mineral density.
It uses low-dose X-rays to assess the mineral content of bones, usually at the hip and spine.
The test is:
- Quick
- Non-invasive
- Generally painless
- Associated with a very low radiation dose
DXA can help doctors diagnose osteoporosis, identify low bone density, estimate fracture risk and monitor treatment response.
However, not everyone needs a DXA scan simply because they have reached a certain age. Our doctors consider individual fracture risk and other clinical factors before recommending the test.
What Does a T-Score Mean?
A T-score compares your bone mineral density with that of a healthy young adult.
For postmenopausal women and men aged 50 and older, a commonly used interpretation is:
| T-score | Interpretation |
|---|---|
| −1.0 or higher | Normal bone density |
| Between −1.0 and −2.5 | Osteopenia |
| −2.5 or lower | Osteoporosis |
Our doctors do not interpret the T-score in isolation. They consider the complete clinical picture, including fracture history and other risk factors.
For younger adults, doctors may use a Z-score rather than relying primarily on a T-score.
What Is a Z-Score?
A Z-score compares your bone density with that of people of similar age, sex and other relevant characteristics.
Doctors may use Z-scores particularly when evaluating premenopausal women and men younger than 50.
A low Z-score can prompt doctors to investigate whether an underlying medical condition or medication is contributing to low bone density.
What Is FRAX?
FRAX, or the Fracture Risk Assessment Tool, helps estimate a person’s probability of experiencing certain osteoporotic fractures over a defined period.
The assessment incorporates factors such as:
- Age
- Sex
- Previous fractures
- Family history
- Smoking
- Alcohol use
- Certain medications
- Other clinical risk factors
- Bone mineral density when available
Our doctors use fracture-risk assessment alongside DXA results to decide whether treatment is appropriate.
Do You Need a Bone Density Test?
Not everyone needs osteoporosis screening at the same age.
Current USPSTF recommendations support screening for:
- Women aged 65 years and older
- Postmenopausal women younger than 65 who have increased osteoporosis risk based on clinical assessment
The USPSTF currently considers the evidence insufficient to determine the balance of benefits and harms of routine osteoporosis screening in men.
Other professional guidelines may use additional risk-based approaches.
Therefore, our doctors individualise the decision based on your age, sex, menopausal status, fracture history and other risk factors rather than recommending a DXA scan to everyone.
When Should You Consider an Osteoporosis Assessment Earlier?
You may need earlier evaluation if you:
- Experience a fracture after a minor injury
- Have suffered multiple fractures
- Have early or premature menopause
- Have a strong family history of osteoporosis
- Have significantly low body weight
- Take long-term corticosteroids
- Have a medical condition associated with bone loss
- Have a history of falls
- Have unexplained height loss
- Develop persistent back pain
- Have other significant osteoporosis risk factors
A previous fragility fracture deserves particular attention because it can indicate a higher future fracture risk.
What Tests May Be Needed Apart From DXA?
DXA provides important information about bone density, but doctors may recommend additional tests when they suspect secondary osteoporosis.
Depending on your history, these may include blood tests that evaluate:
- Calcium
- Vitamin D
- Kidney function
- Liver function
- Thyroid function
- Blood counts
- Other hormone or metabolic markers when clinically indicated
The exact tests depend on your symptoms, medical history and suspected cause.
How Is Osteoporosis Treated?
The main goal of osteoporosis treatment is to reduce the risk of fractures.
Treatment may include:
- Lifestyle measures
- Adequate nutrition
- Appropriate calcium and vitamin D intake
- Exercise
- Fall prevention
- Treatment of underlying medical conditions
- Prescription osteoporosis medicines when indicated
Our doctors choose treatment according to fracture risk, age, sex, bone density, previous fractures, other medical conditions and medication-related factors.
Not everyone with low bone density requires the same treatment.
Lifestyle Measures for Osteoporosis
Lifestyle changes form an important part of osteoporosis management, whether or not you also require medication.
Regular Exercise
A suitable exercise programme can help maintain bone and muscle strength.
Doctors may recommend a combination of:
- Weight-bearing exercise
- Resistance training
- Muscle-strengthening exercises
- Balance exercises
People with severe osteoporosis or previous fractures may need to modify certain movements. A physiotherapist or doctor can help create a safe programme.
Balanced Nutrition
A balanced diet should provide adequate:
- Calcium
- Vitamin D
- Protein
- Fruits and vegetables
- Overall calories and nutrients
Dietary requirements vary between individuals.
Avoid Smoking
If you smoke, quitting can support bone health and reduce your risk of several other diseases.
Limit Excessive Alcohol
Heavy alcohol consumption can negatively affect bone health and increase fall risk.
Prevent Falls
Fall prevention becomes particularly important once osteoporosis develops.
You can reduce fall risk by:
- Improving lighting at home
- Removing loose rugs and obstacles
- Using appropriate footwear
- Installing handrails where necessary
- Improving balance and muscle strength
- Reviewing medicines that cause dizziness or drowsiness
- Addressing vision problems
What Is the Role of Calcium and Vitamin D?
Calcium provides an important structural component of bone, while vitamin D helps the body absorb calcium and supports normal bone and muscle function.
However, taking large amounts of calcium or vitamin D does not automatically strengthen bones.
Our doctors consider your dietary intake, medical history, kidney function, vitamin D status and fracture risk before recommending supplements.
If you have a deficiency or cannot obtain adequate nutrients through your diet, your doctor may recommend supplementation.
Medicines Used to Treat Osteoporosis
Doctors may use different types of medicines depending on the patient’s fracture risk and overall health.
1. Bisphosphonates
Bisphosphonates reduce bone breakdown and can lower fracture risk.
Examples include:
- Alendronate
- Risedronate
- Zoledronic acid
- Ibandronate
For high-risk postmenopausal women, clinical guidelines commonly consider bisphosphonates an initial treatment option. However, the choice depends on the individual patient.
Some bisphosphonates are taken orally, while others can be given intravenously.
Doctors may reassess fracture risk after several years of treatment to determine whether therapy should continue or whether a temporary treatment break is appropriate for selected patients.
2. Denosumab
Denosumab is an antiresorptive medicine that reduces bone breakdown.
Doctors may use it as an alternative initial treatment for some postmenopausal women at high fracture risk.
Patients receiving denosumab need appropriate follow-up. You should not delay or stop denosumab on your own, because stopping without subsequent osteoporosis treatment can lead to rapid changes in bone turnover and increased fracture risk.
3. Bone-Building Medicines
Doctors may consider anabolic or bone-forming medicines for selected patients who have a very high fracture risk, including some people with multiple fractures.
Examples include medicines such as:
- Teriparatide
- Abaloparatide
The decision depends on the patient’s fracture history, bone density and overall clinical situation.
4. Other Osteoporosis Medicines
Depending on the patient’s sex, age, menopausal status, fracture risk and medical history, doctors may consider other approved treatments.
Your orthopaedic or osteoporosis specialist should select the most appropriate medicine after assessing your individual risk.
Can Osteoporosis Be Cured?
Osteoporosis is generally considered a chronic condition, but doctors can manage it effectively.
Treatment can:
- Slow bone loss
- Improve or maintain bone density
- Reduce fracture risk
- Improve overall bone health
- Address contributing medical conditions
Some patients experience improvements in bone mineral density with treatment, but the primary goal remains reducing fractures rather than simply increasing a DXA number.
Consistent follow-up also matters because fracture risk can change over time.
How Is Osteoporosis Monitored?
Our doctor monitor osteoporosis through:
- Changes in bone mineral density
- New fractures
- Changes in clinical risk factors
- Medication adherence
- Treatment side effects
- Relevant blood tests when required
High-risk patients may undergo repeat DXA testing at intervals determined by their doctor. The Endocrine Society recommends monitoring BMD in high-risk individuals with low bone density at approximately 1–3 year intervals, depending on clinical circumstances.
Osteoporosis in Women
Women face an increased risk of osteoporosis after menopause because declining oestrogen levels can accelerate bone loss.
Risk may increase further if a woman:
- Experiences early menopause
- Has a previous fracture
- Has low body weight
- Smokes
- Has a family history of osteoporosis
- Uses long-term corticosteroids
- Has certain medical conditions
Women should therefore discuss their individual fracture risk with their doctor, particularly around and after menopause.
Osteoporosis in Men
Osteoporosis does not affect only women.
Men also lose bone mass with age and can develop osteoporosis, particularly when other risk factors are present.
These factors can include:
- Increasing age
- Previous fractures
- Low testosterone
- Long-term corticosteroid use
- Excessive alcohol consumption
- Smoking
- Low body weight
- Certain chronic illnesses
Men who experience a fracture after relatively minor trauma should not assume that the fracture resulted solely from the injury. Doctors may need to investigate underlying bone weakness
What Is Steroid-Induced Osteoporosis?
Long-term use of corticosteroids, such as prednisolone, can increase bone loss and fracture risk.
The risk depends on factors such as:
- Dose
- Duration of treatment
- Underlying disease
- Age
- Other osteoporosis risk factors
If you need long-term corticosteroid treatment, talk to your doctor about protecting your bones.
Never stop corticosteroids suddenly or change your prescribed dose without medical advice.
Our Doctors assess fracture risk and recommend appropriate preventive or therapeutic measures when necessary.
Can Exercise Help People With Osteoporosis?
Yes, but the type and intensity of exercise matter.
Appropriate exercise can help maintain:
- Muscle strength
- Balance
- Mobility
- Physical independence
- Bone health
Weight-bearing and resistance exercises can provide useful mechanical stimulus to bones.
However, people with established osteoporosis, especially those with vertebral fractures, may need to avoid certain high-impact activities or movements that place excessive stress on weakened bones.
A personalised exercise programme can therefore provide greater benefit than simply exercising more.
How Can You Prevent Osteoporosis?
You cannot eliminate every risk factor for osteoporosis, but you can address many modifiable factors.
Start by:
- Staying physically active
- Performing appropriate weight-bearing and resistance exercise
- Eating a balanced diet
- Getting adequate calcium through diet
- Maintaining adequate vitamin D
- Maintaining healthy muscle strength
- Avoiding smoking
- Limiting excessive alcohol
- Maintaining a healthy body weight
- Managing chronic medical conditions
- Reviewing long-term medicines that affect bone health
- Preventing falls as you get older
The earlier you establish these habits, the more effectively you can support your long-term bone health.
How Can You Prevent Osteoporotic Fractures?
Preventing fractures requires more than improving bone density.
You should also reduce your risk of falls and identify situations that increase your chance of injury.
At Home
- Keep floors and walkways clear.
- Remove loose rugs and unnecessary obstacles.
- Improve lighting.
- Install handrails where appropriate.
- Use bathroom support rails if necessary.
During Daily Activities
- Wear suitable footwear.
- Use walking aids when your doctor recommends them.
- Avoid activities that place unnecessary stress on fragile bones.
- Maintain muscle strength and balance.
During Medical Care
Tell our doctor about your osteoporosis before starting new medicines or treatments that may affect your fall risk.
How Jyoti Hospital Can Help With Osteoporosis
At Jyoti Hospital, Gurugram, our orthopaedic team can help patients evaluate osteoporosis risk, investigate unexpected fractures and develop an appropriate treatment plan.
Depending on your condition, our evaluation include:
- Detailed medical history
- Previous fracture assessment
- Family history
- Menopause and hormonal history where relevant
- Medication review
- Lifestyle and nutritional assessment
- Bone mineral density testing when indicated
- Relevant blood investigations
- Fracture-risk assessment
- Fall-risk assessment
- Individualised treatment planning
- Follow-up of osteoporosis treatment
If you already have osteoporosis, our team can help you understand your diagnosis, treatment options and fracture-prevention measures.
If you have suffered a fracture after a minor fall or injury, we can also assess whether underlying bone weakness may have contributed to the fracture.
Our approach focuses not only on treating the fracture but also on addressing the underlying bone health that may influence your future fracture risk.
When Should You See an Orthopaedic Doctor?
Consider a bone-health evaluation if you:
- Experience a fracture after a minor fall
- Have suffered multiple fractures
- Have unexplained persistent back pain
- Notice unexplained loss of height
- Develop a stooped posture
- Have early menopause
- Have a strong family history of osteoporosis
- Take long-term corticosteroids
- Have a medical condition that can weaken bones
- Have concerns about low bone density
- Have been diagnosed with osteopenia and want to understand your future risk
You should seek medical attention promptly after a suspected fracture, particularly if you have known osteoporosis.
Final Thoughts
Osteoporosis can weaken bones silently, but you do not have to wait for a fracture before addressing your bone health.
Age, menopause, family history, low body weight, physical inactivity, smoking, excessive alcohol consumption, certain medical conditions and long-term medications can all influence your risk.
Our doctors diagnose osteoporosis through a combination of clinical assessment, bone mineral density testing and, when appropriate, additional investigations. Treatment may include lifestyle measures, fall prevention, calcium and vitamin D optimisation, and prescription medicines for people who have a sufficiently high fracture risk.
Most importantly, osteoporosis treatment should remain individualised. A DXA result alone does not tell the entire story, and not everyone with low bone density requires the same treatment.
At Jyoti Hospital, Gurugram, our orthopaedic team can help assess your risk, investigate unexplained or fragility fractures, evaluate bone density when appropriate and develop a personalised plan to protect your bones and reduce future fracture risk.
Stronger bones mean fewer fractures, greater mobility and greater independence as you age.

FAQs
- What are the first signs of osteoporosis?
- Osteoporosis usually has no early symptoms. An unexpected fracture, loss of height, persistent back pain or a stooped posture caused by vertebral fractures can indicate significant bone loss.
- Is osteoporosis the same as osteopenia?
- No. Osteopenia describes lower-than-normal bone density that does not meet the usual diagnostic threshold for osteoporosis. Osteoporosis represents more significant bone loss and a higher fracture risk.
- What is the best test for osteoporosis?
- A central DXA or DEXA scan of the hip and spine is the standard bone-density test used to diagnose osteoporosis and assess bone mineral density.
- Can osteoporosis be reversed?
- Treatment can improve or maintain bone density and significantly reduce fracture risk in appropriate patients. However, osteoporosis requires long-term management and follow-up.
- Do calcium and vitamin D cure osteoporosis?
- No. Calcium and vitamin D support normal bone health, but supplements alone do not replace osteoporosis treatment when prescription medication is indicated.
