Sarcopenia: loss of muscle mass

Muscle changes can affect the legs, hips, arms and trunk. You may notice reduced grip, trouble rising from a chair, slower walking, poorer balance or less ability to carry familiar objects. Muscle weakness and difficulty walking can have many causes, so these signs do not by themselves confirm sarcopenia. A clinician considers your history, examination, strength and physical performance. See [Sarcopenia](/conditions/sarcopenia/) for the condition overview.

Arrange an assessment if strength or function is changing. A physiotherapist can choose progressive resistance exercises, balance work and activity that match your ability. [Strength Training Rehabilitation](/treatments/physiotherapy-and-rehabilitation/strength-training-rehabilitation/) and [Exercise Therapy](/treatments/physiotherapy-and-rehabilitation/exercise-therapy/) may be discussed. Regular meals with adequate protein, treatment of contributing illnesses and safe daily movement can support the plan. Increase effort gradually and use support when balance is uncertain.

Seek prompt medical assessment for rapidly worsening weakness, a new inability to stand or walk, repeated falls, fainting, severe pain, chest symptoms or sudden one-sided weakness. A new fall with a head injury or severe limb pain needs urgent attention. For ongoing unsteadiness, ask about a [Falls Prevention Programme](/treatments/physiotherapy-and-rehabilitation/falls-prevention-programme/).

Could another illness, medicine, nutrition problem or period of inactivity explain my change in strength? Which measurements will you use? What exercise intensity is suitable, and how should I progress it? Should I see a physiotherapist or dietitian?
