Causes of Fatigue

Other times, fatigue could be borne out of more worrying causes. The lack of sleep, for example, may come out of the condition sleep apnea – where a person stops breathing for a moment while slumbering, causing him or her to wake up. Heart diseases, lung diseases, and any form of malnutrition or nutritional deficiency (which, might we add, are more common in “on-the-go” cultures”) would also explain the persistent lack of energy, exhaustion, or weakness that a person might experience. Some medications can also cause fatigue, so it is important that you keep in touch with your doctor. Cancer has fatigue symptoms as well, so never think that being tired is harmless.

Fatigue, on the other hand, is not simply a matter of being tired. Fatigue means that not only do you feel that you are not up to doing any work or handling any other responsibility, but also that you are drained of practically all energy, your drowsiness does not go away, and that you feel as if you are sick – and often, you WILL be sick. Because it's not easy to get rid of fatigue, it is fairly common for people who are suffering from it to feel depressed and frustrated. Because of this, it is recommended that you visit your physician when you start showing signs of fatigue (being tired all the time, etc.).
