Is osteoporosis more common in women than men?
Osteoporosis is significantly more common in women than in men, though it remains a serious health concern for both genders. Statistics in the UK show that women are at a much higher risk of developing the condition and sustaining the fragility fractures associated with it. This disparity is primarily due to biological differences in bone structure and the significant impact of hormonal changes that occur during the menopause. Understanding why these differences exist is essential for identifying those at the highest risk and implementing effective prevention strategies.

Women are statistically more likely to develop osteoporosis and suffer related fractures.
In the United Kingdom, it is estimated that 1 in 2 women over the age of 50 will experience a fracture due to osteoporosis, compared to 1 in 5 men. This means that women are more than twice as likely as men to suffer a broken bone because of weakened bone density. While millions of people are affected across the country, the majority of diagnoses and subsequent treatments are focused on the female population.
The high prevalence in women is one of the reasons bone health is a major focus of postmenopausal care in the UK. According to the NHS, women often have smaller, thinner bones than men to begin with. When bone loss begins later in life, women have less “bone reserve” to lose before their skeleton reaches the threshold of fragility. This structural difference, combined with hormonal shifts, creates a higher vulnerability to conditions like osteoporosis and its precursor, osteopenia.
The menopause is the single most significant reason for the higher rates in women.
The hormone oestrogen plays a vital role in maintaining bone strength in women. It helps to regulate the cells that build new bone and those that break down old bone. During the menopause, oestrogen levels drop significantly and rapidly. This hormonal shift disrupts the balance of bone remodelling, causing the body to break down bone tissue much faster than it can replace it.
In the first five to seven years following the menopause, some women can lose up to 20% of their total bone density. This rapid phase of bone loss is a primary driver of the high osteoporosis statistics seen in women over 50. NICE guidance highlights the menopause as a critical period for bone health assessment, particularly for women who experience an early menopause (before the age of 45), as they lose the protective benefits of oestrogen even sooner.
Men typically reach a higher peak bone mass than women in early adulthood.
Biological differences in bone development also contribute to the gender gap in osteoporosis. During puberty and early adulthood, men generally develop larger and denser skeletons than women. By the time peak bone mass is reached, usually in the late twenties, men have a more robust skeletal structure. This larger frame provides a greater degree of protection as bone density naturally begins to decline from the mid-thirties onwards.
Because men start with more bone mass and do not typically experience a sudden, sharp drop in hormones like the menopause, they often reach the point of “porous” or fragile bones much later in life than women. However, this does not mean men are immune. As men age, their testosterone levels decline gradually, and their rate of bone loss eventually catches up with that of women in their 70s and 80s.
Greater life expectancy in women increases the window for bone loss to occur.
Statistically, women in the UK have a longer life expectancy than men. While living longer is a positive trend, it also means that women have more years in which age-related bone loss can occur. Since bone density decreases progressively with age, the oldest members of the population, who are predominantly female, are at the highest risk for severe osteoporosis and complex fractures, such as hip fractures.
This longevity factor, combined with the earlier onset of bone thinning after the menopause, means that women spend a larger portion of their lives with potentially fragile bones. Public health initiatives often target women in their 50s and 60s for screening to ensure that bone health is managed proactively throughout these later decades of life.
Osteoporosis in men is often underdiagnosed because it is seen as a female condition.
One of the challenges in managing bone health is the misconception that osteoporosis only affects women. Because of this, men are often less likely to be screened for the condition or to seek medical advice for signs of bone thinning, such as a loss of height. When men develop osteoporosis, it is often related to specific underlying causes such as long-term steroid use, excessive alcohol consumption, or low testosterone levels (hypogonadism).
While the prevalence is lower, the consequences for men can be just as severe. Research indicates that men may actually have a higher mortality rate following a hip fracture than women, partly because they are often older and have more underlying health issues at the time of the injury. It is vital for men with risk factors to be aware that bone health is a universal concern and that they should not ignore the possibility of osteoporosis.
Conclusion
Osteoporosis is significantly more common in women than men, largely due to the impact of the menopause and differences in peak bone density. With 1 in 2 women over 50 expected to sustain a fracture, the condition represents a major health priority for the female population in the UK. However, the 1 in 5 men affected should not be overlooked, as bone thinning is a universal part of the ageing process. Regardless of gender, maintaining a healthy lifestyle and understanding your personal risk factors are the best ways to protect your skeleton. If you have concerns about your bone density or have experienced a fracture from a minor fall, seek a medical review. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Do men and women take the same medications for osteoporosis?
Yes, many of the primary treatments, such as bisphosphonates, are used effectively by both men and women in the UK to strengthen bones.
Is HRT effective for preventing osteoporosis in women?
Hormone Replacement Therapy (HRT) can help maintain bone density by replacing the oestrogen lost during the menopause, though it is prescribed on an individual basis.
At what age should women start worrying about bone health?
Bone health is important at all ages, but women should be particularly mindful as they approach the menopause, typically in their late 40s or early 50s.
Can men get osteoporosis from low testosterone?
Yes, testosterone helps maintain bone mass in men; if levels are abnormally low, the rate of bone loss can increase significantly.
Are hip fractures more common in women?
Yes, the majority of hip fractures in the UK occur in women, reflecting the higher overall prevalence of osteoporosis in the female population.
Do lifestyle changes work differently for men and women?
No; weight-bearing exercise, a diet rich in calcium, and avoiding smoking are equally effective strategies for supporting bone health in both genders.
Is osteoporosis hereditary for both sons and daughters?
Yes, a family history of osteoporosis or hip fractures increases the risk for both male and female descendants.
