  1. a) Generalized weakness: Generalized weakness is the condition characterized by the presence of overall fatigue. The patient may not able to point out the exact location and present a low feeling.
  2. b) Neurological weakness: Various neurological disorders are also responsible for the weakness in patients. This is due to the fact that nerves are the primary control mechanism for energy production. Any disorder in this control system causes a reduction in energy. The neurological conditions include multiple sclerosis, Parkinson’s disease, and amyotrophic lateral sclerosis.
  3. c) Muscular weakness: Weakness may also occur due to muscular disorder. Type of muscular fatigue includes central fatigue, neuromuscular fatigue, and peripheral muscle fatigue.
  4. d) Cancer weakness: The patient, in its initial stages of cancer, may suffer from weakness, fatigue, and unexplained weight loss.
  5. e) Chronic disease weakness: Chronic as well acute condition, if not managed properly, may lead to weakness. Chronic conditions such as diabetes and acute conditions such as anemia and infection cause weakness.

If the patient has unexplained weight loss along with weakness and other symptoms such as night sweating, there might be chances of cancer. The blood test is done to evaluate the presence of anemia and other infections. Blood sugar can also be diagnosed through HBA1C.

Risks if neglect

The various risk exists when the weakness, as a symptom, is neglected. Weakness or fatigue is a symptom which may be due to the serious underlying disease. Delay in the diagnosis of underlying disease may lead to serious, sometimes fatal, consequences. Neglecting weakness may take a toll on the quality of life of the patient. The patient may not be able to perform routine work and has low enthusiasm. Further, the patient may get detached from society and starts living in isolation.


The fatigue or weakness has three stages and the patient may prevent the progression of weakness by taking preventive measures to stop the condition at that particular stage. Following are the stages of weakness:

  1. A) Initial stage:  This stage is characterized by the presence of high concentration of cytokines indicating that the body is fighting against disease. However, the concentration remains high during the initial stage of fatigue.
  2. B) Increased fatigue: When the symptoms of the initial stage are ignored, the disease progressed into the next level of fatigue. The progression of this condition varies from patient to patient. Further, the condition also depends upon the underlying cause.
  3. C) Exhaustion: Exhaustion is the condition which is severely debilitating, and the energy of the person is at an all-time low. The patient is not able to perform routine activities while the brain function also suffers.
