Diarrhea is the condition when a person is having at least three liquid bowel movements per day. It usually lasts for a few days.
The most dangerous thing about the condition is that it can result in dehydration due to fluid loss, and this is especially dangerous for children. The first signs of dehydration usually begin with loss of the skin stretchiness, dry mouth, and irritable behavior.
The three main types of diarrhea include acute diarrhea, persistent diarrhea, and dysentery. If diarrhea lasts less than two weeks, it is called acute diarrhea. It can cause dehydration and lead to malnutrition. If it comes to death, it is usually due to dehydration.
When diarrhea lasts longer than two weeks, we talk about persistent diarrhea. About 20 percent of diarrhea episodes become persistent. It can cause nutritional problems, lead to malnutrition, dehydration, and serious non-intestinal infection.
Bloody diarrhea – often with mucus – is called dysentery. It is very dangerous because it can lead to anorexia, extreme weight loss, and damage the intestines. Another danger of dysentery is sepsis.
