Diarrhea in Adults - Infectious Disease and Antimicrobial Agents
It affects most people from time to time and is usually nothing to worry about. There are many different causes of diarrhoea, but a bowel infection gastroenteritis is a common cause in both adults and children. These infections can sometimes be caught during travel abroad, particularly to areas with poor standards of public hygiene. This is known as travellers' diarrhoea.
The small intestine and colon are components of your digestive tract, which processes the foods you eat. The intestines extract nutrients from the foods. What isn't absorbed by the intestines continues along the digestive tract and is expelled as stool during a bowel movement. Diarrhea — loose, watery and possibly more-frequent bowel movements — is a common problem.
Diarrhea is an increase in the volume, wateriness, or frequency of bowel movements. See also Diarrhea in Children. The frequency of bowel movements alone is not the defining feature of diarrhea. Some people normally move their bowels 3 to 5 times a day.
