5. Exhaustion
Chronic fatigue is related to liver disease. Of course there might be a number of other reasons. However, if you feel exhausted and tired, check your liver and let your doctor see whether the levels of noradrenaline, serotonin and corticotropins are good. Exhaustion, according to researchers, may be worsened by an increase in toxic byproducts present in the blood. If your liver is damaged, it cannot clean the blood properly hence you feel exhausted and constantly tired.
