Asthenia is the medical term for weakness that is caused due to several reasons, including physical situations and major illnesses. The prognosis of Asthenia can also be termed as weakness that is caused due to the lack or depletion of muscle strength, feeling dizzy and fatigue.
The most common causes of asthenia are skeletal and muscle diseases. Other causes of Asthenia are sleep disorders and some chronic disorders of the heart, as well as the lungs and kidneys. Asthenia can also be caused because of some of the chronic diseases like tuberculosis. Asthenia is also caused as a side effect and is part of the symptoms of some medicines and vaccines, especially those used in HIV treatment and HPV.
Asthenia symptoms are quite straightforward. Because of the muscle weakness, people feel tiredness and are slow in movement. Some might even experience muscle twitching while others would feel loss or lack of energy. Because of the sudden change in physical strength, some might show confusion too.
Asthenia can also be caused because of lifestyle issues. A sedentary lifestyle may also be the cause of this illness, as such a lifestyle results in muscle wasting, where the muscle fiber is replaced with fats. Due to this replacement, the muscle becomes flaccid. Other reasons of Asthenia can range from age, infections and in some cases, pregnancy, to drug abuse, chemotherapy, radiation therapy and depression.
Asthenia is sometimes misconstrued by lay people as a mental condition, generally because though they feel all right and energetic, they find it difficult and sometimes impossible to carry out day to day activities because of the incessant weakness that they experience. However, there is no connection between Asthenia and any mental condition.
The concept and illness of Asthenia can be divided into Asthenia and Myasthenia. Myasthenia can be described as where the patients feel that they are exerting more effort while carrying out muscular functions, but the actual strength of the muscle has not depleted or deteriorated.
Asthenia has several causes, and therefore there is no ‘one size fits all’ treatment for Asthenia. As and when the major medical condition is treated, Asthenia seems to fade way too. Also, apart from Asthenia caused due to lifestyle, there is no way to prevent it. The treatment cost would depend on what kind of treatment is required.
