Can younger adults in the UK develop osteoporosis?
While osteoporosis is most frequently associated with older age and the menopause, it can and does affect younger adults in the UK. When the condition occurs in people under the age of 50, it is often referred to as secondary osteoporosis, meaning the bone thinning is caused by an underlying medical condition, a specific medication, or lifestyle factors. Although it is relatively rare for a younger person to experience significant bone loss without a clear cause, the impact can be serious, as the skeleton is typically at its peak strength during these years.

Osteoporosis in younger adults is usually linked to another health issue.
In most cases, younger adults do not develop osteoporosis spontaneously. Instead, the condition is usually “secondary” to another primary health problem. When a young person is diagnosed with low bone density, UK healthcare professionals will often investigate underlying causes that might be interfering with the body’s ability to build or maintain bone tissue. Because younger people are generally expected to have strong bones, a fragility fracture in this age group is a significant clinical red flag.
The biological process is the same as in older adults; the body breaks down bone faster than it replaces it, but the triggers are different. In younger people, the bone-building process may have been interrupted during the critical years of bone development, or an external factor may be accelerating bone loss prematurely. Identifying the root cause is the first step in managing the condition effectively.
Certain chronic medical conditions can lead to early bone thinning.
Several health conditions are known to affect bone density in younger adults. Conditions that cause chronic inflammation, such as rheumatoid arthritis, Crohn’s disease, or ulcerative colitis, can directly stimulate the cells that break down bone. Furthermore, conditions that affect the absorption of nutrients, such as Coeliac disease, can lead to a deficiency in calcium and vitamin D, both of which are essential for skeletal strength.
Hormonal disorders are another major cause. For women, conditions that cause the absence of periods (amenorrhoea) for long periods, such as polycystic ovary syndrome (PCOS) or excessive exercise, can lead to low oestrogen levels, which weaken bones. In men, low testosterone levels can have a similar effect. According to NICE guidance, individuals with these conditions should be monitored for signs of bone density loss more closely than the general young population.
Long-term use of specific medications is a well-known risk factor.
The medications used to treat other serious health issues can sometimes have the unintended side effect of thinning the bones. The most common culprits are corticosteroids (such as prednisolone), which are used to treat a variety of inflammatory and autoimmune conditions. If taken at high doses for more than three months, steroids can significantly reduce bone formation and increase bone resorption.
Other medications that may impact bone health in younger adults include some treatments for epilepsy, certain antidepressants, and medications used to manage endometriosis or breast cancer that suppress sex hormones. When these medications are necessary for a young person’s health, UK doctors often consider preventative measures, such as recommending Vitamin D supplements, to mitigate the impact on the skeleton.
Pregnancy-associated osteoporosis is a rare but serious occurrence.
A very small number of women develop osteoporosis during pregnancy or in the months following childbirth. This is known as pregnancy-associated osteoporosis (PAO). The exact cause is not fully understood, but it is thought to be related to the increased demand for calcium by the developing baby, combined with hormonal changes.
Women with this rare condition may experience severe back pain or even spinal fractures during or shortly after pregnancy. While the condition can be distressing, the prognosis is often good, as bone density typically improves once the woman finishes breastfeeding and her hormone levels return to normal. Any woman experiencing severe, unexplained back pain during or after pregnancy should seek a medical assessment to rule out bone-related issues.
Lifestyle factors and eating disorders can severely impact bone development.
The years between puberty and age 30 are the most critical for building “peak bone mass.” If this process is disrupted by poor nutrition or certain lifestyle choices, a young adult may enter their 30s with much weaker bones than average. Eating disorders, such as anorexia nervosa, are particularly damaging to bone health because they combine severe nutritional deficiencies with low hormone levels, often leading to rapid and significant bone loss in teenagers and young adults.
Other factors that can hinder bone development include a completely sedentary lifestyle, heavy smoking, and excessive alcohol consumption. Because bones need the stress of weight-bearing activity to grow strong, a lack of movement during the formative years can leave the skeleton fragile. Addressing these factors early in life is the best way to prevent the early onset of osteoporosis.
Conclusion
While osteoporosis is far more common in older age, it can affect younger adults in the UK, usually as a result of underlying health conditions, medications, or lifestyle factors. Early diagnosis is vital for preventing long-term complications and fractures during a person’s most active years. By managing primary health issues and ensuring adequate nutrition and exercise, many younger adults can protect and even improve their bone density. If you are under 50 and have experienced a fracture from a minor fall, or if you have a condition known to affect bone health, it is important to discuss a bone density review with a healthcare professional.
Can teenagers get osteoporosis?
Yes, though rare, it is usually called juvenile osteoporosis and is typically linked to medical conditions or long-term medication use.
Is a DEXA scan standard for young people?
DEXA scans are not routine for the under-50s unless there are specific risk factors, such as a fragility fracture or a known high-risk medical condition.
Can young adults improve their bone density?
Yes, younger adults still have a good capacity for bone remodelling, and with the right treatment and lifestyle changes, they can often improve their T-scores.
Does a lack of periods always mean bone loss?
Not always, but long-term absence of periods significantly increases the risk because it usually indicates low oestrogen levels.
Are there specific exercises for young people with thin bones?
Weight-bearing exercises like running or tennis are excellent for building bone, but they should be tailored to the individual if a fracture risk is already present.
Can Coeliac disease cause osteoporosis in your 20s?
Yes, if left undiagnosed or unmanaged, Coeliac disease can prevent the absorption of calcium, leading to early bone thinning.
Is early-onset osteoporosis hereditary?
Genetics play a role in peak bone mass, so a strong family history of the condition may increase the risk for younger family members.
