3. Stool Changes

If you experience trouble with the movements of the bowels, you will suffer from constipation. It becomes difficult to defecate and causes great discomfort. Constipation can sometimes happen to a healthy person too. If it is chronic, you should pay attention to this. IBS or, in other words, irritable bowel syndrome, is a condition when constipation alternates with diarrhea. This may be accompanied with abdominal pain and a sudden need to pass bowel movements. Another thing that tells that your liver is damaged is when you notice that your stool is pale in color.
