Symptom

Muscle weakness

Muscle weakness means that muscle strength is lower than usual and everyday movements cannot be performed as they normally would. The symptom may appear suddenly or develop gradually, and it can affect a single muscle, a group of muscles, or the whole body. Muscle weakness can show up, for example, as difficulty rising from a chair, lifting the arms, or climbing stairs, and sometimes it can also cause muscles to tire quickly during exertion.

The most common causes in Finland include musculoskeletal disorders, such as back problems, prolonged inactivity, and the age-related decrease in muscle mass. Neurological diseases, such as myasthenia gravis, can also cause muscle weakness. In some cases, muscle weakness may be associated with serious illnesses, such as a cerebrovascular disorder or inflammation.

Muscle weakness is a concerning symptom if it appears suddenly, worsens rapidly, is associated with other symptoms such as speech difficulties or numbness, or significantly impairs everyday functioning. In unclear or rapidly progressing situations, it is important to seek assessment from a healthcare professional without delay.
