DIARRHEA Symptom Definition Diarrhea is the sudden increase in the frequency and looseness of BMs (bowel movements, stools). Mild diarrhea is the passage of a few loose or mushy BMs. Severe diarrhea is the passage of many watery BMs. General Information The majority of adults with diarrhea of less than two weeks duration have an infectious cause for their diarrhea, and in most cases the infection is a virus. Other common causes of acute diarrhea are food poisoning and medications. Maintaining good hydration is the cornerstone of treatment of adults with acute diarrhea. In general, an adult who is alert, feels well, and who is not thirsty or dizzy - is not dehydrated. Antibiotic therapy is only rarely required in the treatment of acute diarrhea. One type of acute diarrhea that requires antibiotic therapy is Traveler's Diarrhea.

Diarrhea is the body's way of getting rid of the infection.  Here are some tips on how to keep ahead of the fluid losses. Fluids: Drink more fluids, at least 8-10 glasses (8 oz) daily. For example: sports drinks, diluted fruit juices, soft drinks. Supplement this with saltine crackers or soups, to make certain that you are getting sufficient fluid and salt to meet your body's needs. Nutrition: Maintaining some food intake during episodes of diarrhea is important. Ideal initial foods include boiled starches/cereals (e.g. potatoes, rice, noodles, wheat, oats) with a small amount of salt to taste. Other acceptable foods include: bananas, yogurt, crackers, soup. As your stools return to normal consistency, resume a normal diet. Diarrhea Medication - Bismuth Subsalicylate (e.g. PeptoBismol): Helps reduce diarrhea, vomiting, and abdominal cramping. Adult dosage: two tablets or two tablespoons by mouth every hour (if diarrhea continues) to a maximum of 8 doses in a 24-hour period.
