Osteoporosis is a condition that affects the bones, causing them to become weak and fragile and more likely to break (fracture).
These fractures most commonly occur in the spine, wrist and hips but can affect other bones such as the arm or pelvis.
In childhood, bones grow and repair very quickly, but this process slows as you get older. Bones stop growing in length between the ages of 16 and 18, but continue to increase in density until you are in your late 20s. From about the age of 35, you gradually lose bone density. This is a normal part of ageing, but for some people it can lead to osteoporosis and an increased risk of fractures.
Other things that increase the risk of developing osteoporosis include:
Read more about the causes of osteoporosis.
There are often no warning signs for osteoporosis until someone experiences a fracture, often after a minor fall.
Read more about the symptoms of osteoporosis.
If your doctor suspects you have osteoporosis, or are at high risk of developing the condition, you may be referred for a bone density scan (DEXA scan). This is a short and painless procedure that helps to assess your risk of a fracture.
Read more about diagnosing osteoporosis.
Treatment for osteoporosis is based on treating and preventing fractures and using medication to strengthen your bones.
However, the decision about what treatment, if any, you have will depend on your risk of fracture. This will be based on a number of things such as the results of your DEXA scan and your age.

It is important that people at risk of osteoporosis take steps to help keep bones healthy and reduce their risk of developing the condition. This may include:

Although commonly associated with post-menopausal women, osteoporosis can also affect men, younger women and children.
If you are diagnosed with osteoporosis, there are steps you can take to reduce your chances of a fall, such as removing hazards from your home and having regular sight and hearing tests.
There are ways to help your recovery from a fracture. This might include:
If you are worried about living with a long-term condition, speak to your doctor or nurse who may be able to answer any questions you have. Some people with osteoporosis find it helpful to talk to a trained counsellor or psychologist, or to others with the condition.

Osteoporosis develops slowly over several years. It is likely there will be no warning signs or symptoms until a minor fall or sudden impact causes a bone fracture.
Healthy bones should be able to withstand a fall from standing height, so a bone that breaks in these circumstances is known as a fragility fracture.
The most common injuries in people with osteoporosis are:
A simple cough or a sneeze may cause the fracture of a rib or the partial collapse of one of the bones of the spine.
A fractured bone in an older person can be serious, depending on where it occurs, and can lead to long-term disability. For example, a hip fracture may lead to long-term problems with mobility.
One visible sign of osteoporosis is the characteristic stooping (bent forward) position that develops in older people. It happens when the bones in the spine are fractured, making it difficult to support the weight of the body.
Osteoporosis usually doesn't cause pain unless a bone is broken as a result of the condition. Although not always painful, spinal fractures are the most common cause of chronic pain associated with osteoporosis.
Osteoporosis is caused by bones losing their density. Some people are more at risk than others.
Bones are at their thickest and strongest in early adult life and are constantly renewed and repaired through a process called bone turnover. However, as you age, this process is no longer balanced and bone loss increases. This means bone is very slowly broken down over time and your bones become less dense as you get older. This leads to the bone becoming weaker and more likely to fracture.
Osteoporosis can affect men and women. It is more common in older people, but it can affect younger people too.
Women are at greater risk of developing osteoporosis than men. This is because changes in hormone levels can affect bone density. The female hormone oestrogen is essential for healthy bones. After the menopause, the level of oestrogen in the body falls, and this can lead to a rapid decrease in bone density. Women are at even greater risk of developing osteoporosis when:
For most men who develop osteoporosis, the cause is unknown. However, there is a link to the male hormone testosterone, which helps to keep the bones healthy. Men continue to produce this hormone into old age, but the risk of osteoporosis is increased in men with low levels of testosterone.
In around half of men the exact cause of this is unknown, but known causes include:
Many hormones in the body can affect the process of bone turnover. If you have a disease of the hormone-producing glands, you may be at higher risk of developing osteoporosis. Osteoporosis can be triggered by hormone-related diseases, including:
Other things thought to increase the risk of osteoporosis and broken bones include:
Osteoporosis is often diagnosed after the weakening of the bones has led to a fracture.
If you at high risk of osteoporosis your doctor may refer you for a bone density scan, known as a DEXA scan.
X-rays are not a reliable method of measuring bone density, but are a useful way of identifying fractures.
A DEXA (dual energy X-ray absorptiometry) scan can help diagnose osteoporosis. It is a painless procedure that takes around 15 minutes to perform.
It measures your bone mineral density (BMD) and compares it to the bone density of a healthy young adult and someone who is of the same age and sex as you.
The difference between your BMD measurement and that of a healthy young adult is calculated as a standard deviation (SD) and called a T score. Standard deviation is a measure of variability based on an average or expected value. A T score of:
A bone density scan can help diagnose osteoporosis, but your BMD result is not the only factor that determines your risk of fracturing a bone.
Your doctor will also consider your age, sex and any previous injuries before deciding whether you need treatment for osteoporosis.
If you do need treatment, your doctor will suggest the safest and most effective treatment plan for you.
Although a diagnosis of osteoporosis is based on the results of your bone mineral density (DXA) scan, the decision about what treatment, if any, you have can be based on a number of factors, including your risk of fracture. If you’ve been diagnosed with osteoporosis because you’ve had a fracture, you should still be treated to try to reduce the risk of any further fractures.
You may not need or want to take drugs to treat your osteoporosis. However, you should maintain good levels of calcium and vitamin D in your body. Your healthcare team may advise a change to your diet or taking supplements to do this.
There are a number of different drug treatments for osteoporosis. Your doctor will discuss the treatments available and make sure the medicines are right for you.

Bisphosphonates work by slowing the rate at which the cells that break down bone (osteoclasts) work. This maintains bone density and reduces the risk of fracture. There are a number of different bisphosphonates, including alendronate, etidronate, ibandronate, risedronate and zolendronic acid. They are given as a tablet or injection.
The main side effects associated with bisphosphonates include irritation to the oesophagus, trouble swallowing and stomach pain, but not everyone will experience these. Osteoneocrosis of the jaw is a rare side effect linked with the use of bisphosphonates (more frequently with high-dose intravenous bisphosphonate treatment for cancer and not for osteoporosis). The cells in the bone of the jaw die, and this can lead to problems with healing. If you have a history of dental problems, you may need a check-up before you start this treatment. If you have any concerns, speak to your doctor.
Strontium ranelate appears to have an effect on both the cells that break down bone and the cells that create new bone (osteoblasts). It can be used as an alternative treatment if bisphosphonates are found to not be suitable. Strontium ranelate is taken as a powder dissolved in water.
The main side effects associated with strontium ranelate are nausea and diarrhoea. A few patients have reported a rare, severe allergic reaction to the treatment. If you develop a skin rash while taking strontium ralenate, stop taking it and speak to your doctor immediately.
SERMs are drugs that have a similar effect on bone as the hormone oestrogen. They help maintain bone density and reduce the risk of fracture, particularly at the spine. The only form of SERM available for the treatment of osteoporosis is raloxifene. Raloxifene is taken as a tablet every day.
Side effects associated with raloxifene include hot flushes, leg cramps and a potential increased risk of blood clots.
Parathyroid hormone is produced naturally in the body. It regulates the amount of calcium in bone. Parathyroid hormone treatments (human recombinant parathyroid hormone or teriparatide) are used to stimulate cells that create new bone (osteoblasts). They are given by injection. While other drugs can only slow down the rate of bone thinning, PTH can increase bone density. However, it is only used in a small number of people whose bone density is very low and where other treatments aren’t working.
Common side effects include nausea and vomiting. Parathyroid hormone treatments should only be prescribed by a specialist.
Calcium and vitamin D supplements can benefit older men and women and reduce their risk of hip fracture. Having enough calcium as part of a healthy balanced diet is important to maintain healthy bones. Aim to eat or drink 700mg of calcium each day. This is roughly equivalent to one pint of milk. If you are not getting enough calcium in your diet, ask your doctor for advice about taking a calcium supplement. To have the right effect on your bones and help prevent falls or fracture, or in treatment of osteoporosis, you need the right dose of calcium (1.2g a day) and vitamin D (20 micrograms). These doses only occur in a small number of branded formulations prescribed by doctors, so any pills you buy over the counter may not have enough calcium and generally no vitamin D.
HRT is used for women going through the menopause as it can help to control symptoms. In addition, HRT has been shown to maintain bone density and reduce the risk of fracture during treatment. However, HRT is not specifically recommended as a treatment for osteoporosis and is now almost never used. This is because there is a risk that HRT slightly raises the chance of developing certain conditions, such as breast cancer, endometrial cancer, ovarian cancer and stroke, more than it lowers the risk of osteoporosis. Discuss the benefits and risks of HRT with your doctor.
Read more information about understanding the risk of HRT.
Calcitonin is a hormone made by the thyroid gland. It inhibits the cells that break down bone (osteoclasts), which increases bone density. Calcitonin or salcatonin are taken as a nasal spray or an injection every day. Side effects include nausea, vomiting and diarrhoea.
Testosterone treatment for men is useful when osteoporosis is due to an insufficient production of male sex hormones (hypogonadism).
Although your genes determine your potential height and the strength of your skeleton, lifestyle factors such as diet and exercise can influence how healthy your bones are.
Regular exercise is essential. Adults should do at least 150 minutes (2 hours and 30 minutes) of moderate-intensity aerobic activity (i.e. cycling or fast walking) every week. Weight-bearing exercise and resistance exercise are particularly important in improving bone density and helping prevent osteoporosis.
If you’ve been diagnosed with osteoporosis, it’s a good idea to talk to your doctor or health specialist before you take up any new exercise activity, to make sure it’s right for you.
Weight-bearing exercises are exercises where your feet and legs support your weight. High-impact weight-bearing exercises, such as running, skipping, dancing, aerobics and even jumping up and down on the spot, are all useful ways to strengthen your muscles, ligaments and joints. When exercising, wear footwear that provides your ankles and feet with adequate support, such as trainers or walking boots.
People over the age of 60 can also benefit from regular weight-bearing exercise. This can include brisk walking, keep-fit classes or a game of tennis. Swimming and cycling are not weight-bearing exercises.
Resistance exercises use muscle strength, where the action of the tendons pulling on the bones boosts bone strength. Examples include press-ups, weightlifting or using weight equipment at a gym. If you have recently joined a gym or have not been for a while, your gym will probably offer you an induction. This involves being shown how to use all the equipment and recommended exercise techniques. If you are unsure how to use a piece of equipment or how to do an exercise, ask a gym instructor for help.

Calcium is important for maintaining strong bones. The recommended intake of calcium is at least 700mg a day. This is about equivalent to one pint of milk. Calcium can also be found in a number of different foods, including green leafy vegetables, dried fruit, tofu and yoghurt.
Vitamin D is also important for bones and teeth as it helps your body to absorb calcium. Vitamin D can be found in eggs, milk and oily fish. However, most vitamin D is made in the skin in response to sunlight. A short exposure to sunlight, without sunscreen (10 minutes twice a day) throughout the summer should provide you with enough vitamin D for the whole year.
Certain groups of people may be at risk of not getting enough vitamin D. These include people who may be housebound or particularly frail, people with a poor diet or who keep covered up in sunlight because they wear total sun block or adhere to a certain dress code, and women who are pregnant or breastfeeding. If you are at risk of not getting enough vitamin D through your diet or lifestyle, you can take a vitamin D supplement. For adults, 10 micrograms a day of vitamin D is recommended. The recommended amount for children is 7 micrograms for babies under six months, and 8.5 micrograms for children aged six months to three years. Talk to your doctor for more information.
Other lifestyle factors that can help prevent osteoporosis include:
Phyllis Long, aged 60, was recently diagnosed with osteoporosis after months of experiencing upper back pain.
“I had severe pain in the right side of my upper back for about one month, and decided I needed to see my doctor. My back was so sore when anything touched it that even lying in bed was uncomfortable. It felt like my very bones were sore.
“I went to see my doctor in January and he wondered if I was experiencing thinning of my bones because of my age and my medical history. I’d had a few breakages in the past 10 years. He referred me to a consultant orthopaedic and spine surgeon, and he prescribed diclofenac painkillers to keep the pain at bay.
“The consultant suggested I have an MRI scan on my back and a bone density scan on my back and hips, which would measure the calcium in my bones. The MRI showed that I had arthritis in my lower three vertebrae, and the bone density scan gave me my T score. I was told that the T score baseline was 0 and that a score between 1 and 3 would be ‘normal’. Unfortunately, the scan revealed that my hips, at -1.3, were in the osteopenic level, and my spine, at -3, was in the osteoporotic level.
“The score meant that I definitely had osteoporosis, and that my back was worse than my hips. My doctor indicated that the emergency hysterectomy I had after the birth of my second child could have been a factor in developing osteoporosis. I was very taken aback. I'd led a healthy life, eating lots of fresh fruit and taking plenty of exercise. Plus, there was no history of osteoporosis in my family.
“My consultant told me that they would treat the condition with a tablet, called alendronic acid, which I now have to take once a week for the rest of my life. It’s from a group of non-hormonal medicines, known as bisphosphonates, which prevent bone loss from the body.
“I walk regularly and am active in the garden. The medical advice was to continue all activity as normal, as exercise would help increase the amount of calcium in my bones.
“I had to provide a list of the foods I regularly ate, so the doctor could see if there were any gaps in my diet. As I don’t have a very large intake of calcium, the doctor also prescribed chewable calcium tablets for me to take daily. I was given a list of high-calcium content foods, such as yoghurt, semi-skimmed milk, cheeses, whitebait, sardines and spinach, which I was advised to eat to boost my calcium intake.
“Within 24 months, I'll have another bone scan and my doctor is confident that my bone density will have increased significantly. For now, I'm waiting for an appointment with a rheumatologist, who I assume will help me further in dealing with the condition.”
If you have any questions, your doctor or nurse may be able to reassure you. You may also find it helpful to talk to a trained counsellor or psychologist, or to someone at a specialist helpline. Your doctor surgery will have information on these.
Some people find it helpful to talk to others who have osteoporosis, either at a local support group or in an internet chat room.
Broken bones usually take six to eight weeks to recover. Having osteoporosis does not affect how long this takes. Recovery depends on the type of fracture you have. Some fractures heal easily, but others may require more intervention.
If you have a complicated wrist fracture or hip fracture, you may need an operation to make sure that the bone is set properly. Hip replacements are often needed after hip fractures and some people may lose mobility as a result of weakened bones.
Osteoporosis can cause a loss of height as a result of fractures in the spinal column. This means the spine is no longer able to support your body's weight and it causes a hunched posture. This can be painful when it occurs, but it may also lead to chronic (long-term) pain. Your doctor or nurse may be able to help with this.
During the healing process, you may need the help of a physiotherapist or occupational therapist so you can make as full a recovery as possible.
Read more information about physiotherapy.
The experience of pain is unique to every individual, so what works for you may differ from what works for someone else. There are a number of different ways of managing pain, including:
To manage your pain, it is possible to use more than one of these approaches at the same time (for example, using a drug treatment, heat pack and relaxation techniques).
You should be able to continue to work when you have osteoporosis. It's very important that you remain physically active and have a fulfilled lifestyle. This will help keep your bones healthy and stop you from focusing too much on your potential health problems. However, if your work involves the risk of falling or breaking a bone, seek advice from your employer, doctor and the National Osteoporosis Society about how best to limit your risk of having an accident or injury that could lead to a bone break.
If you cannot continue working, you may be eligible for disability and incapacity benefits. People over 65 who are severely disabled may qualify for a disability benefit called Attendance Allowance.
Carers may also be entitled to some benefit, depending on their involvement in caring for the person with osteoporosis.
Dorothy Borbas was diagnosed with osteoporosis at 75 years of age.
“I discovered that I had osteoporosis in 1999, three days after I turned 75. I was in bed and had a cramp in my leg. When I got out of bed to stop the cramping, I fell and fractured two vertebrae. Before my fractures, I didn't realise that I had osteoporosis. It was some time before I received a firm diagnosis from the hospital. I then sought the help of the National Osteoporosis Society (NOS).
“The NOS provided me with an absolute lifeline. I was able to speak at length with a nurse who put my mind at ease and gave me detailed information on diet, exercise and treatments.
“I joined my local NOS support group. I am now an active member and enjoy helping to organise local fundraising activities.”
Bob Rees was diagnosed with osteoporosis after collapsing in pain on a family holiday.
“I was 43 when I was diagnosed with osteoporosis. I was on a family holiday in the Dominican Republic in June 2002, when I collapsed in agony. In March 2003, nine months later and after extensive tests, I was diagnosed with severe spinal osteoporosis. I remember my relief at being told that I didn’t have bone cancer, as had been suspected, but my relief was short-lived when I was told that I had the bones of an 80-year-old.
“I turned to the National Osteoporosis Society (NOS) for support and I'm now an ambassador for the charity. I find that talking to other people with osteoporosis helps me deal with my own pain, and I advise anyone who has recently been diagnosed with osteoporosis to try to keep active. Don’t sit back and give in. Small lifestyle changes, such as walking or swimming, can help keep your bones healthy.”
