The reduction of power in muscle of body is termed as weakness. This weakness may involve one or more muscle. The generalized body weakness is hard to notice and is usually ignored till it gets severe. The weakness becomes more pronounced when it involves a local area with a few muscles.



Different causes that may result in weakness are:

  • Stroke

  • Nerve injury

  • Metabolic disorders like Addison’s disease

  • Neurologic disorders like cerebral palsy

  • Muscle diseases such as myotonic dystrophy

  • Botulism

  • Anemia

  • Myasthenia gravis

  • Polio



Inability to perform activities with a limb, hand or a side of a body is a general sign. The muscle becomes flaccid and cannot bear the normal pressure and weight. The discoloration and sensory loss may be present with weak muscle.



The diagnosis of weakness is made by a complete history of the patient. The patient will be asked about the location of weakness, degree of weakness, associated symptoms and duration of weakness. In addition to general physical examination, blood tests, urine analysis and other imaging tests may be required to confirm the area and cause of weakness.



  • Treatment involves excluding the underlying body problems and determining the exact causes of weakness.

  • Physiotherapy, supplements and other drugs according to patient’s conditions are advised by the doctors usually.

  • Getting an adequate rest can also cure the weakness and remove the fatigue if it is caused by overwork.

  • In cases of flu and other medical conditions, spending a few days at home without the work can make it better. Providing body rest and exercise in balanced states can help avoid this condition.
