What is osteoporosis?
Osteoporosis is a health condition that weakens bones, making them fragile and more likely to break. It develops slowly over several years and is often only diagnosed when a sudden impact or minor fall causes a bone fracture. While bone density naturally decreases as people age, this condition involves a more significant loss of bone strength than is typical.

Osteoporosis is a condition where bones lose density and quality, leading to an increased risk of fractures.
The human body constantly absorbs and replaces bone tissue. In a healthy body, this process is balanced. However, when someone has osteoporosis, the creation of new bone does not keep up with the removal of old bone. This results in the internal structure of the bone becoming porous and brittle. The most common injuries in people with osteoporosis are broken wrists, hip fractures, or fractures in the spinal bones.
In many cases, a person may not realise they have the condition until a minor accident leads to a serious injury. This is why it is often referred to as a “silent” condition. It affects millions of people in the UK, particularly older adults and women following the menopause.
Several factors can increase the likelihood of developing weakened bones.
While anyone can develop osteoporosis, certain groups are at higher risk. Women are generally more susceptible because they often have smaller bones than men and experience a rapid decrease in oestrogen levels during the menopause. Oestrogen is essential for maintaining bone density, and when levels drop, bone loss accelerates.
Other risk factors include a family history of the condition, a low body mass index (BMI), and the long-term use of certain medications, such as high-dose steroid tablets. Lifestyle choices also play a significant role. Regular smoking, heavy alcohol consumption, and a lack of weight-bearing exercise can all contribute to the thinning of bone tissue over time.
Diagnosis usually involves a specialized scan to measure bone mineral density.
If a healthcare professional suspects osteoporosis, they will likely use a tool called a DEXA scan to measure bone strength. This is a short, painless procedure that uses low-dose X-rays to determine how much calcium and other bone minerals are packed into a segment of bone. The results are typically given as a T-score, which compares the individual’s bone density to that of a healthy young adult.
A T-score of -2.5 or lower is generally used to diagnose osteoporosis. Doctors also use assessment tools, such as FRAX, to predict a person’s risk of suffering a fracture over the next decade. These assessments help determine whether medication is necessary or if lifestyle adjustments are sufficient to manage the risk.
Treatment focuses on strengthening bones and preventing future fractures.
The management of osteoporosis depends on the severity of the bone loss and the individual’s risk of breaking a bone. Medications known as bisphosphonates are commonly prescribed in the UK. These drugs work by slowing down the rate at which bone is broken down in the body. This helps to maintain bone density and reduces the risk of fractures in the spine and hip.
In addition to medication, ensuring adequate intake of calcium and vitamin D is vital. Calcium is the primary building block of bone tissue, while vitamin D helps the body absorb calcium effectively. Most adults require around 700mg of calcium a day, which can usually be obtained through a balanced diet including dairy products, green leafy vegetables, and nuts.
Lifestyle adjustments are essential for maintaining bone health and safety.
Staying active is one of the most effective ways to protect bone health. Weight-bearing exercises, where your feet and legs support your weight, are particularly beneficial. This includes activities such as brisk walking, dancing, or low-impact aerobics. Resistance exercises, like using weights or elastic bands, also help by strengthening the muscles that support the bones.
Safety at home is another critical consideration for those with the condition. Reducing the risk of falls can prevent fractures that often lead to complications. This may involve removing trip hazards like loose rugs, ensuring rooms are well-lit, and wearing supportive, non-slip footwear. Regular eye tests and hearing checks are also recommended to help maintain balance and coordination.
Conclusion
Osteoporosis is a manageable condition characterised by reduced bone density and an increased risk of fractures. While it is often associated with the natural ageing process, early diagnosis through bone density scans and proactive lifestyle changes can significantly improve outcomes. By focusing on nutrition, regular exercise, and fall prevention, individuals can maintain their independence and bone strength. If you experience sudden, severe pain in your back or a fracture following a minor bump, it is important to seek medical advice to assess your bone health.
Can osteoporosis be cured completely?
While bone density lost to osteoporosis cannot be fully reversed, the condition can be effectively managed, and the risk of fractures significantly reduced through treatment.
Does osteoporosis cause pain before a bone breaks?
Generally, the condition itself does not cause pain; discomfort usually only occurs once a bone has been fractured or a spinal vertebra has collapsed.
Is it safe to exercise if I have thin bones?
Yes, exercise is encouraged, but it should be tailored to your ability and bone strength to avoid high-impact activities that might cause a fall.
Are men affected by osteoporosis?
Yes, although it is more common in women, men can also develop osteoporosis, often due to low testosterone levels or long-term medication use.
Should I take a vitamin D supplement?
The NHS recommends that everyone in the UK consider taking a daily 10-microgram vitamin D supplement during the autumn and winter months to support bone health.
How often should I have a bone density scan?
The frequency of scans depends on your individual risk factors and whether you are on treatment, but it is typically every two to five years.
Does smoking affect bone density?
Yes, smoking is linked to a higher risk of osteoporosis as it can interfere with the cells that build bone and may lower oestrogen levels.
