osteoporosis risks and benefits for patients

Overview

Osteoporosis is a condition that makes bones weak, thin, and more likely to break. The word 'osteoporosis' means 'porous bone.' Inside a healthy bone, there is a honeycomb-like structure. In osteoporosis, the holes in this honeycomb become larger, so the bone has less density and strength. Even a minor bump or fall can cause a fracture.

Yes, osteoporosis is very common. It affects millions of people worldwide. In the UK, around 3 million people are estimated to have osteoporosis. Most are over 50 years old, but younger people can also get it.

Osteoporosis can affect anyone, but it is most common in women after menopause because of the drop in estrogen, a hormone that helps protect bones. Men also get osteoporosis, but usually later in life. People with a family history, certain medical conditions, or those taking certain medications are at higher risk.

Symptoms

Common symptoms

• There are usually no symptoms in the early stages.
• A broken bone (fracture) is often the first sign.
• Loss of height over time.
• A stooped posture or curved upper back.
• Sudden back pain that may be due to a spinal fracture.

Symptoms in children

• Childhood osteoporosis is rare and usually caused by another medical condition or medication.
• Signs may include bone pain, difficulty walking, or fractures with very little injury.
• Children may also have slower growth or a curved spine.

Symptoms in older adults

• Breaks that happen more easily than expected, like after a small bump or fall from standing height.
• Hip fractures often cause severe pain and inability to walk.
• Spine fractures can cause sudden back pain, height loss, and a hunched forward posture.
• Wrist fractures can occur when trying to break a fall.

Causes

Main causes

• Bone is living tissue that breaks down and rebuilds. Osteoporosis happens when the body loses too much bone, makes too little bone, or both.
• After menopause, women's estrogen levels drop, which speeds up bone loss.
• Aging naturally causes bones to become less dense and weaker.
• Some medical conditions, such as thyroid problems, kidney disease, or eating disorders, can affect bone health.

Risk factors

• Being female and over 50 years old.
• Low body weight or being very thin.
• Family history of osteoporosis or hip fracture.
• Low levels of calcium or vitamin D in your diet.
• Smoking or drinking more than a few alcoholic drinks per week.
• Long-term use of certain medications like corticosteroids (steroids).
• Being inactive or not doing enough weight-bearing exercise.
• A history of fractures in a parent or sibling.

When to see a doctor

See a doctor urgently if:

• If you break a bone after a minor fall or injury, you should be seen promptly.
• If you have sudden severe back pain, especially after a fall, get medical help the same day.
• If you have lost height or notice a new curve in your spine, see a doctor soon.

Book a routine appointment if:

• Talk to your doctor about bone health if you are over 50 and have any risk factors.
• If you take long-term steroids or medicines that affect your hormone levels, ask about a bone density test.
• If you are a woman approaching or past menopause, it is a good time to review your bone health.

Diagnosis

Doctors often diagnose osteoporosis with a special X-ray test called a DEXA scan (dual-energy X-ray absorptiometry). This test measures bone mineral density — in simple terms, how strong and dense your bones are. It is painless and takes about 10 to 20 minutes. Your doctor may also ask about your medical history and do blood tests to rule out other causes of bone loss.

Tests that may be done

• DEXA scan (DXA) to measure bone density at the hip and spine.
• Blood tests to check calcium, vitamin D, thyroid, and kidney function.
• Sometimes urine tests to see if bones are breaking down too quickly.
• A fracture risk assessment tool, like FRAX, which uses your age, weight, and other factors to estimate your chance of breaking a bone.

What to expect at your appointment

After a DEXA scan, you are given a 'T-score'. A score of -1 or higher is normal, between -1 and -2.5 means low bone mass (osteopenia), and -2.5 or lower means osteoporosis. Your doctor will explain your results and what they mean for your risk of breaking a bone. They will also discuss a plan to help keep your bones as strong as possible.

Treatment

Treatment for osteoporosis focuses on slowing bone loss, building new bone, and preventing fractures. Medicines can help, but they work best when combined with good nutrition and exercise. When deciding on treatment, your doctor will weigh the benefits of preventing a break against the risks of any possible side effects. Talk openly with your doctor about your concerns.

Self-care at home

• Make sure you get enough calcium and vitamin D — from foods or supplements if your doctor recommends.
• Do regular weight-bearing exercise like walking, dancing, or climbing stairs to help build bone.
• Do muscle-strengthening exercises with weights or resistance bands.
• Avoid smoking and limit alcohol to no more than a couple of drinks per week.
• Take steps to prevent falls, such as removing loose rugs, using night lights, and wearing sturdy shoes.

Medical treatments

Several groups of medicines can help treat osteoporosis. Some work by slowing down the cells that break down bone, while others help the body build new bone. These medicines are usually given as tablets or injections. Your doctor or specialist will decide which type is right for you based on your age, fracture risk, and other conditions. It is important to discuss how long you need to take a medicine, as some have rare side effects. You will also be advised to keep up your calcium and vitamin D intake while on treatment.

When is surgery considered?

Surgery is generally not used to treat osteoporosis itself. It is used to repair fractures that have already happened, such as a hip or wrist fracture. In some cases, a procedure called kyphoplasty or vertebroplasty may be considered for painful spine fractures, but this is not right for everyone. Your doctor will explain your options if you have a break.

Living with this condition

Living with osteoporosis means being mindful about protecting your bones while still staying active. Simple changes can make a big difference: avoid lifting heavy items, bend at the knees instead of the waist, and use a walking aid if you feel unsteady. Keep your home free of clutter and bright to avoid falls.

Lifestyle tips

• Stay active with safe, low-impact exercises like swimming, cycling, or tai chi.
• Practice balance exercises to reduce fall risk.
• Get enough sleep and manage stress — both can affect bone health.
• Ask your pharmacist to review your medicines for any that may make you dizzy and increase fall risk.

Diet and exercise

A bone-healthy diet includes foods rich in calcium, such as dairy products, leafy green vegetables, and fortified cereals. Vitamin D is also essential — it helps your body absorb calcium. You can get vitamin D from sunlight, but in many countries a daily supplement is advised during certain seasons. For exercise, aim for a mix of weight-bearing activities, like brisk walking or jogging, and strength training to support your bones and muscles.

Mental health and emotional wellbeing

Living with osteoporosis can be stressful, especially if you worry about falling or breaking a bone. It is normal to feel anxious or frustrated. These feelings can make it harder to stay active, so it is important to talk about them. If you feel down, speak to your doctor or a mental health professional. You are not alone, and getting support can help you feel more in control.

Prevention

You can reduce your risk of osteoporosis by building strong bones at every age. A diet rich in calcium and vitamin D, regular weight-bearing exercise, and avoiding smoking and heavy alcohol use all help. If you have risk factors, talk to your doctor about your bone health before a fracture happens. It is never too early or too late to take protective steps.

Screening programmes

Screening means checking for low bone density before you break a bone. In the UK, this is not done for everyone. Your doctor may suggest a DEXA scan if you have risk factors or after a fracture. Ask your doctor if a bone density test is appropriate for you.

Complications

If left untreated

• Bones may become so weak that they break even without a fall.
• Spinal fractures can cause severe pain, height loss, and a hunched posture.
• Hip fractures can require surgery and make it hard to walk or live independently.
• Multiple fractures can affect your quality of life and lead to disability.

Long-term outlook

With proper diagnosis and treatment, most people with osteoporosis can slow down bone loss and greatly reduce their risk of fractures. Advances in treatment have made a real difference. Even if you already have osteoporosis, the future is not a downward path — many people continue to enjoy active lives. Work closely with your healthcare team, stay positive, and take it one step at a time.
