Asthenia is a medical term that refers to a condition characterized by generalized physical weakness and a lack of energy or strength. It is not classified as a disease itself but is rather a common symptom associated with various acute and chronic medical conditions. Individuals experiencing asthenia may feel fatigued physically, emotionally, or cognitively, which can interfere with their daily activities. The sensation of weakness often feels disproportionate to the level of activity being performed and can be persistent and distressing. Asthenia may manifest as weakness in specific body parts or affect the entire body, leading to difficulties in carrying out routine tasks
