Sarcopenia: New Indian Guidelines Highlight Hidden Muscle Loss Threat in Ageing Adults

Ageing is commonly associated with visible signs such as wrinkles, greying hair and slower metabolism. However, doctors warn that a far more serious change often occurs silently within the body — the gradual loss of muscle mass and strength, known as sarcopenia. New Indian clinical guidelines have recently highlighted this under-recognised condition, urging healthcare professionals to identify and manage it early to prevent disability and frailty among older adults. As India’s population continues to age, experts believe sarcopenia could become a significant public health challenge affecting mobility, independence and overall quality of life.

Sarcopenia is a progressive skeletal muscle disorder linked with ageing and characterised by reduced muscle strength, declining physical performance and increased vulnerability to falls, fractures and chronic diseases. Research suggests that muscle loss can begin as early as mid-life and tends to accelerate after the age of 60. For many individuals, the condition develops gradually and may remain unnoticed until it begins to interfere with routine activities such as climbing stairs, carrying groceries or standing up from a chair.

Studies estimate that nearly four in ten elderly adults in India may be affected by sarcopenia, underscoring the scale of the problem. The condition is also closely associated with other health disorders. Evidence indicates that sarcopenia is linked with metabolic conditions such as diabetes, cardiovascular disease and insulin resistance, further increasing the burden on healthcare systems.

To address the lack of region-specific diagnostic standards, a multidisciplinary panel of experts has developed India-specific consensus guidelines using a modified Delphi method. The recommendations aim to standardise screening practices and improve early diagnosis.

The guidelines advise routine screening for individuals above 60 years of age and for those with chronic illnesses that may increase the risk of muscle loss. Measurement of handgrip strength using a handheld dynamometer has been recommended as a simple and reliable diagnostic tool. For the Indian population, low muscle strength is defined as less than 27.5 kg in men and less than 18 kg in women. Patients diagnosed with sarcopenia should be monitored regularly, typically every three to six months.

Management strategies emphasise lifestyle-based interventions rather than medication. Resistance or strength training is considered the most effective way to improve muscle mass and physical function. Adequate protein intake, generally around 1.0–1.2 grams per kilogram of body weight per day for older adults, is also recommended. Vitamin D and other micronutrients play an important role in maintaining muscle health and balance.

Experts emphasise that sarcopenia is not an inevitable consequence of ageing. With early screening, proper nutrition and regular physical activity, muscle decline can be slowed or even reversed. Strengthening muscle health throughout adulthood may therefore be one of the most important strategies for promoting healthy ageing and maintaining independence in later life.
