Why do I have chronic diarrhea?

For the last month and a half, I've had diarrhea almost everyday. What usually causes chronic diarrhea?

Constipation is usually due to slow motility of the colon, sometimes in the setting of irritable bowel syndrome. Increasing fiber, fruits, and use of laxatives will help.
-Lactose intolerance
-Gluten intolerant
-Patient had surgery on the small intestines
-Parasite
Multiple reasons possible for chronic diarrhea. Please see your physician. Hope that helps.
The most common causes of CHRONIC diarrhea are MANY -- a few of the most common are:

-IRRITIBLE BOWEL syndrome
-DRUGS/MEDICATIONS (antibiotics/LAXATIVES/certain artificial sweeteners/etc. -- but ANY DRUG must be considered in the right setting)
-INFECTIONS -- Giardia, worms, antibiotic associated diarrhea (caused by C. Difficile)
-INFLAMMATION -- Crohn's or Ulcerative colitis
-LAXATIVE ABUSE
-ENDOCRINE -- hyperthryoidism or diabetes
-MALABSORPTION -- pancreatic exocrine deficiency (where not enough enzyme is secreted into the bowel to be able to absorb fat/nutrients)

It also must be said that the DEFINITION of true "diarrhea" is the STOOL VOLUME -- and NOT just having "loose" stools. So, >400cc of stool per day is considered true "diarrhea." Anything LESS than that is not abnormal (ASSUMING THE PERSON IS EATING/DRINKING; AS IF THE PERSON IS NOT EATING/DRINKING, DEFECATION MAY BE REDUCED OR STOPPED NO MATTER WHAT THE CAUSE).
