Aging and Sarcopenia: Recognising Muscle Loss

Some change in muscle occurs with aging, but sarcopenia is a clinical problem rather than a label for every older person. Inactivity, inadequate food intake, chronic illness and recovery after hospitalisation can contribute to a decline in muscle function.

Clues include increasing difficulty rising from a chair, climbing steps, carrying shopping, opening containers or keeping pace while walking. Repeated falls, slower movement and needing more help with familiar tasks can reveal loss of strength before a change in muscle size is obvious.

Assessment may include questions about falls and daily activities, a medicine and nutrition review, and measurements of grip strength, chair-rise ability or walking performance. Muscle quantity may also be measured when needed. Clinicians look for treatable contributors such as undernutrition, reduced activity or another health condition.

Progressive resistance exercise is central to management. A physiotherapist or qualified exercise professional can adapt sit-to-stand practice, resistance bands, weights and balance work to current ability. The challenge should increase gradually while movements remain controlled and symptoms stay acceptable.

Adequate energy and protein intake supports muscle rebuilding alongside activity. A dietitian can help when appetite is poor, chewing or swallowing is difficult, weight is falling, or kidney and other medical conditions affect food choices. A falls prevention programme can also address footwear, vision, medicines and hazards at home.

Arrange a timely review for unexplained weakness, repeated falls, unplanned weight loss, a clear decline after illness, or growing difficulty with walking and self-care. Early assessment can identify causes that need treatment and establish a safe starting point for rehabilitation.

Call emergency services for sudden one-sided weakness, facial drooping, speech difficulty, collapse, severe breathlessness or chest pain. Sudden weakness is not the gradual pattern expected from sarcopenia and may signal an acute medical emergency.

Ask which strength and walking checks are appropriate, whether medicines or illness could be contributing, and whether physiotherapy or dietetic support would help. Discuss how to begin resistance training, how progress will be measured, and what changes would make exercise unsafe.
