Women, Menopause And Bone Health: Doctor Explains Why Osteoporosis Risk Rises After 40

World Osteoporosis Day 2026 was observed on October 20th, drawing attention to a condition that can weaken bones over time without causing obvious symptoms. For women, the years leading up to menopause are particularly important for bone health.

As estrogen levels decline, bone loss can accelerate, increasing the risk of osteoporosis and fractures. Since this process often goes unnoticed until an injury occurs, understanding the changes that begin in the 40s can help women take timely steps to protect their bones.

Dr. Roopal Panchani, Adult & Pediatric Endocrinologist & Diabetologist, Aadicura Superspeciality Hospital, Vadodara, explains how menopause affects bone density, why Indian women need to pay attention to osteoporosis risk, and what can help maintain bone strength.

Why Estrogen Matters To Bone Health

"Bone being a living tissue constantly breaks and gets built with peak bone mass reached by the early thirties. Estrogen acts as a brake on bone breakdown. As levels decline during perimenopause and after menopause that brake loosens and density begins to fall." Dr. Panchani points out.

The loss is steepest in the first five to seven years after the final period, when a woman can lose up to 20 per cent of her bone density. Because the decline begins during the perimenopausal years, often in the early to mid-forties, the forties are the time to start paying attention to bone health.

Why Indian Women Need To Be Especially Alert

The timing of menopause, nutritional deficiencies and lifestyle habits can all influence bone health. Indian women may experience menopause earlier than women in many Western populations, potentially increasing the number of years spent with lower estrogen levels. Vitamin D deficiency, diets that fall short on calcium and protein, and limited outdoor activity can add to the risk.

Dr. Panchani highlights the importance of understanding these differences when assessing osteoporosis risk among Indian women. She adds, "Local data matter. Our diets, vitamin D levels and lifestyles differ from those in Western studies, so we should not assume Western numbers describe Indian women. What we do see is that many arrive at menopause with less bone in the bank."

Who Is At A Higher Risk Of Osteoporosis?

Menopause is a significant risk factor, but other medical and lifestyle factors can further increase a woman's chances of developing osteoporosis. Identifying these risks early can help women understand whether they need closer monitoring or preventive care.

Factors that can increase osteoporosis risk include:

• Menopause before the age of 45.
• Surgical removal of the ovaries.
• A family history of osteoporosis or hip fracture.
• Vitamin D deficiency.
• Long-term steroid use.
• Thyroid and parathyroid disorders.
• Type 2 diabetes.
• Smoking and heavy alcohol use.
• A sedentary lifestyle.
• A previous fracture following a minor fall or low-impact injury.

Women with these risk factors may benefit from discussing their bone health with a healthcare professional, particularly during perimenopause and after menopause.

What Women Can Do To Protect Their Bones

Although age-related and menopause-related bone loss cannot always be prevented, certain measures can help preserve bone strength and reduce the risk of fractures.

• Prioritise Calcium And Vitamin D: Adult women generally need about 1,000 to 1,200 mg of calcium a day, ideally from food such as milk, curd, ragi, sesame, leafy greens and fortified products, with supplements only to fill the gap. Vitamin D supplements should be dosed according to the blood level rather than guesswork.
• Stay Physically Active: Weight-bearing activity such as brisk walking and stair climbing, resistance training, and balance work such as yoga all help preserve bone and reduce falls, which cause most fractures.
• Understand The Role Of Medical Treatment: When bone density is low or fracture risk is high, medicines can slow bone loss or help rebuild bone. Menopausal hormone therapy can protect bone and ease symptoms for some women, but suitability depends on age, years since menopause, and personal and family history of breast cancer, blood clots and heart disease.

Dr. Roopal adds, "Hormone therapy is neither a cure-all nor something to avoid by default. The question is whether it suits this woman, at this age, with this history."

When Should Women Seek Medical Advice?

Osteoporosis does not always cause pain or noticeable symptoms in its early stages, which means women may not realise their bones are weakening until a fracture occurs. Certain changes and medical circumstances, however, warrant attention.

A consultation is worth considering when periods become irregular before 45, or menopause follows surgery, when there is a family history of osteoporosis, when a bone fracture occurs even after a minor fall or low-impact injury, when posture begins to stoop, or when persistent back pain develops without a clear cause. A thyroid or parathyroid disorder, diabetes or long-term steroid use is already part of the picture.

An endocrinologist can assess individual risk, advise a bone density scan (DEXA) along with vitamin D, calcium and hormone tests, and help decide whether lifestyle changes are enough or treatment is needed.

Protecting Bone Health Before Menopause

Bone health deserves attention well before the first fracture. For women approaching menopause, understanding the role of estrogen, maintaining adequate nutrition and staying physically active can help protect bone strength over time. Recognising individual risk factors and seeking timely assessment when necessary can also support mobility and independence as women grow older.
