osteoporosis overview for patients

Overview

Osteoporosis is a condition that makes your bones become weak and brittle. The word means 'porous bone.' Inside healthy bones, there is a honeycomb-like structure. In osteoporosis, the holes in this honeycomb get bigger, so the bone loses density and becomes more likely to break.

Yes. Osteoporosis is common, especially in women after menopause. It affects millions of people around the world. Many people don't know they have it until they break a bone.

Osteoporosis can affect anyone, but it is most common in older adults, particularly women. Men can get it too, usually later in life. People with a family history, a smaller body frame, or certain medical conditions may have a higher risk.

Symptoms

Common symptoms

• Often there are no symptoms in the early stages.
• A stooped posture or loss of height over time.
• Back pain from a collapsed vertebra.
• A bone that breaks more easily than expected.

Symptoms in children

• Osteoporosis is rare in children. When it does happen, it is usually due to another medical condition or medicine. Children may have bone pain or breaks with little injury.

Symptoms in older adults

• In older adults, watch for height loss, a curved upper back, or a broken bone after a minor fall or bump. Back pain that comes on suddenly may be a sign of a spinal fracture.

Causes

Main causes

• Bone is living tissue. Your body is always breaking down old bone and making new bone. Until about age 30, your body makes more bone than it loses. After that, bone loss slowly outpaces bone building. In osteoporosis, this balance is disrupted, and bones become thin and weak. Things that can cause this include changes in hormones (especially lower estrogen in women and lower testosterone in men), not getting enough calcium and vitamin D, and certain medicines (such as long-term steroids).

Risk factors

• Being female, especially after menopause
• Older age
• Family history of osteoporosis or broken bones
• Low body weight or being small and thin
• Smoking and heavy drinking
• Low physical activity
• Poor diet lacking calcium and vitamin D
• Certain medical conditions (like thyroid problems or rheumatoid arthritis)
• Some medicines (like corticosteroids)

When to see a doctor

See a doctor urgently if:

• If you have sudden severe back pain that makes it hard to stand or move
• If you fell and have pain or swelling in a bone or joint

Book a routine appointment if:

• If you are over 50 and broke a bone from a minor fall
• If you have lost height or have a curved spine
• If you have risk factors and want to know your bone health

Diagnosis

A doctor will talk with you about your medical history, family history, and lifestyle. They may check your height and posture. The most common test is a bone density scan, called a DXA (dual-energy X-ray absorptiometry). It is a quick, painless scan that measures bone strength, usually at your hip and spine.

Tests that may be done

• DXA bone density scan
• Blood tests to check calcium, vitamin D, or hormone levels
• Fracture risk calculators (your doctor may use a tool like FRAX)

What to expect at your appointment

The DXA scan is simple. You lie on a padded table, and a scanner passes over your body. It takes about 10 to 20 minutes. You do not need to undress. Your doctor will explain your results as a 'T-score.' A normal score is -1 or higher. A score between -1 and -2.5 means low bone density (osteopenia). A score of -2.5 or lower means osteoporosis.

Treatment

Treatment for osteoporosis focuses on slowing bone loss, building bone strength, and preventing falls and fractures. Your doctor will work with you to make a plan based on your age, your bone density, and your fracture risk.

Self-care at home

• Make sure you get enough calcium (from food or supplements — talk to your doctor first)
• Get enough vitamin D from sunlight, food, or supplements as recommended
• Do weight-bearing exercises like walking, dancing, or stair climbing
• Do muscle-strengthening exercises to improve balance and prevent falls
• Avoid smoking and limit alcohol
• Make your home safer to prevent falls (remove rugs, improve lighting)

Medical treatments

There are several types of medicines that can help strengthen bones. Some work by slowing bone loss, and others help build new bone. Your doctor may also recommend hormone-related therapy in some cases. All of these are prescription treatments, and the right one depends on your individual situation. Always discuss benefits and risks with your healthcare provider.

When is surgery considered?

Surgery is usually not needed for osteoporosis itself. It may be needed if you have a fracture that does not heal well or if a hip fracture requires repair. In certain spinal fractures, a procedure called vertebroplasty or kyphoplasty may be considered, but it is not right for everyone.

Living with this condition

Living with osteoporosis means paying attention to your body and your environment. Stay active, but choose safe activities. Be mindful of your posture. Get up slowly from a lying or sitting position. Use handrails on stairs. Wear shoes with good grip. Talk to your doctor about your daily routines and any concerns.

Lifestyle tips

• Stay physically active every day
• Eat a balanced diet with enough calcium and vitamin D
• Limit caffeine and alcohol
• Quit smoking
• Get regular check-ups and dental care (mouth health matters too)
• Ask about a fall-prevention program or physical therapy

Diet and exercise

Calcium and vitamin D are key for bone health. Good calcium sources include dairy products, leafy green vegetables, fortified plant milks, and canned fish with soft bones. Vitamin D comes from safe sunlight and from foods like oily fish or fortified foods. Some people need supplements — ask your doctor. For exercise, aim for a mix of weight-bearing exercises (like walking or climbing stairs) and resistance training (like light weights or resistance bands) to keep bones strong and improve balance.

Mental health and emotional wellbeing

Living with osteoporosis can feel stressful. You might worry about falls or fractures, or feel frustrated by limits on activities. These feelings are normal. It can help to talk to your doctor, a counsellor, or a trusted friend. Staying socially connected and doing things you enjoy can also boost your mood.

Prevention

You cannot completely prevent osteoporosis, but you can lower your risk and slow bone loss. A healthy diet, regular physical activity, not smoking, and limiting alcohol all help. If you are at higher risk, your doctor can help you find the best plan for you.

Vaccines

Staying up to date with recommended vaccines can help prevent illnesses that might keep you bedbound and speed bone loss.

Screening programmes

Screening for osteoporosis is not for everyone. Your doctor may recommend a bone density test if you are over 50 and have had a broken bone, over 65 and female, or if you have risk factors. Talk to your doctor about when you should be tested.

Complications

If left untreated

• Fractures of the hip, spine, or wrist from everyday activities or minor falls
• Chronic pain and limited mobility after a fracture
• Loss of independence and need for long-term care
• Reduced quality of life from fear of falling

Long-term outlook

Osteoporosis is a manageable condition. With the right treatment, good nutrition, and a focus on fall prevention, many people continue to live full, active lives. It is never too late to improve your bone health. Work with your healthcare team and take it one step at a time.
