Sarcopenia

Sarcopenia is a condition involving reduced muscle strength, muscle quantity or physical performance. It is often associated with ageing, but illness, inactivity and poor nutrition can contribute at any age. The condition can affect walking, transfers, balance and the ability to manage everyday tasks.

Sarcopenia commonly presents with muscle weakness and may also be associated with difficulty walking or muscle cramps. You may notice trouble rising from a chair, climbing stairs, carrying shopping, opening containers or recovering balance. Changes can be gradual, so comparing current abilities with usual daily tasks is useful.

Muscle can decline when it receives less loading, when protein and energy intake are inadequate, or during recovery from illness or hospitalisation. Hormonal changes, long-term inflammatory conditions and medication effects may also contribute. Often, several factors combine rather than one cause explaining every change.

Early loss of strength may appear as slower walking or greater effort with transfers. Without support, reduced activity can lead to further deconditioning and less confidence outdoors. Progress can improve when resistance exercise, adequate nutrition and treatment of underlying illness are addressed together.

Risk factors include older age, prolonged inactivity, recent bed rest, repeated illness, undernutrition, unintentional weight loss and conditions that limit movement. Fear of falling can also reduce activity and accelerate loss of strength. A person who is active may still develop sarcopenia if another health problem affects muscle.

Assessment combines your history with measures of strength, walking or chair-rise performance, and sometimes muscle quantity. A clinician may review nutrition, medications, balance, falls and conditions that affect activity. The purpose is to identify modifiable contributors and establish a safe starting level for exercise.

Exercise is central to care. Exercise therapy and strength training rehabilitation can use progressive resistance, balance work and task practice matched to your ability. Nutrition support may be recommended when intake is low. A falls prevention programme can address footwear, transfers, home hazards and confidence. Progress should be reviewed so the programme remains challenging and safe.

Build movement into the day through short walks, repeated sit-to-stand practice or supervised resistance work. Use a stable support when advised, keep pathways clear and plan rest between demanding tasks. Protein-rich foods and regular meals may support rehabilitation; discuss dietary changes with a qualified professional if appetite or swallowing is a concern.

Reduced strength can make falls, fractures, loss of independence and difficulty recovering from illness more likely. Tell a clinician about repeated falls, sudden functional decline, unexplained weight loss or new difficulty managing basic activities so contributing problems can be assessed.

Regular resistance and balance activity helps maintain capacity, especially after illness or periods of reduced movement. Adequate food intake, treatment of long-term conditions and an early return to safe activity after bed rest can protect function. A physiotherapist can adapt exercises around pain or medical restrictions.

A physiotherapist, geriatrician, rehabilitation physician or dietitian may contribute to care. Look for a team that measures strength and daily function, checks fall risk, and adapts exercise and nutrition advice to your health, equipment and home environment.
