People infected with diarrhea have bowel movements (or stools) which are loose and watery.


Diarrhea is caused by a virus that infects your gut.
Causes include:

Alcohol abuse.
Allergies to certain foods.
Diseases of the intestines (such as Crohn’s disease or ulcerative colitis).
Eating foods that upset the digestive system.
Infection by bacteria (the cause of most types of food poisoning) or other organisms.
Laxative abuse.
Overactive thyroid (hyperthyroidism).
Radiation therapy.
Running (Some people get “runner’s diarrhea” for reasons that aren’t clear).
Some cancers.
Surgery on your digestive system.
Trouble absorbing certain nutrients, also called “malabsorption”.

Diarrhea may also follow constipation, especially people who are suffering from irritable bowel syndrome.


You may have:

Bloating in your belly.
Thin or loose stools.
Watery stools.
An urgent feeling that you need to have a bowel movement.
Nausea and throwing up.

Serious symptoms include:

Blood or mucus in your stool.
Weight loss.

Watery stools more than three times a day and not drinking enough fluids results in dehydration, which causes serious complications if not treated.
