Diarrhea Causes, Symptoms, and Treatment

Diarrhea is the sudden increase in the frequency and looseness of bowel movements (BMs). Mild diarrhea is the passage of a few loose or mushy BMs. Severe diarrhea is the passage of many watery BMs. The best indicator of the severity of the diarrhea is its frequency.
The main complication of diarrhea is dehydration from the loss of too much body fluid. Symptoms of dehydration are a dry mouth, the absence of tears, infrequent urination (for example, none in 12 hours), and a darker, concentrated urine. The main goal of diarrhea treatment is to prevent dehydration.

What is the cause? 
Diarrhea is usually caused by a viral infection of the lining of the intestines (gastroenteritis). Sometimes it is caused by bacteria or parasites. Occasionally a food allergy or drinking too much fruit juice may cause diarrhea. If your child has just one or two loose bowel movements, the cause is probably something unusual your child ate. A diet of nothing but clear fluids for more than 2 days may cause green, watery bowel movements (called "starvation stools").

How long will it last? 
Diarrhea usually lasts several days to a week, regardless of the type of treatment. The main goal of treatment is to prevent dehydration. Your child needs to drink enough fluids to replace the fluids lost in the diarrhea. Don't expect a quick return to solid bowel movements.

What should I feed my child? 
Increased fluids and dietary changes are the main treatment for diarrhea. Note: One loose bowel movement can mean nothing. Don't start dietary changes until your child has had several loose bowel movements.
Frequent, watery diarrhea
  • Fluids Encourage your child to drink lots of fluids to prevent dehydration. Give your child water as the main fluid for the first 24 hours of watery diarrhea. A child who is taking table foods doesn't need to get calories from milk. Most toddlers don't need oral glucose-electrolyte solutions such as Pedialyte unless the child is dehydrated. On day 2, offer some milk as well as water. Avoid fruit juices, because they all make diarrhea worse. If your child refuses solids, give your child milk (or formula) rather than water.
  • Table foods Keep giving your child table foods while he has diarrhea. The choice of food is important. Starchy foods are digested best. Examples of such foods are dried cereals, grains, bread, crackers, rice, noodles, mashed potatoes, carrots, applesauce and bananas. Pretzels or saltine crackers can help meet your child's need for sodium. On the second day of the diarrhea, if your child wants some protein, soft-boiled eggs and yogurt are usually easily digested.
Mild diarrhea (loose BMs)
Follow a regular diet with a few simple changes:
  • Eat more foods containing starch. Starchy foods are easily digested during diarrhea. Examples are cereal, breads, crackers, rice, mashed potatoes, and noodles.
  • Drink more water. Avoid all fruit juices.
  • Eat or drink less milk and milk products for a few days.
  • Avoid beans or any other foods that cause loose bowel movements.

How can I take care of my child?

  • Common mistakes KOOL-Aid, soda pop, or water should not be used as the only food because they contain little or no salt. Use only the fluids suggested here. Clear fluids alone should be used for only 4 to 6 hours because the body needs more calories than clear fluids can provide. The most dangerous myth is that the intestine should be "put to rest." Restricting fluids can cause dehydration. There is no effective, safe drug for diarrhea. Extra fluids and diet therapy work best.
  • Prevention Diarrhea is very contagious. Always wash your hands after changing diapers or using the toilet. This is crucial for keeping everyone in the family from getting diarrhea.
  • Diaper rash from diarrhea The skin near your child's anus can become irritated by the diarrhea. Wash the area near the anus after each bowel movement and then protect it with a thick layer of petroleum jelly or other ointment. This protection is especially needed during the night and during naps. Changing the diaper quickly after bowel movements also helps.
  • Overflow diarrhea in a child not toilet-trained For children in diapers, diarrhea can be a mess. Place a cotton washcloth inside the diaper to trap some of the more watery BM. Use disposable superabsorbent diapers to cut down on cleanup time. Use the diapers with snug leg bands or cover the diapers with a pair of plastic pants. Wash your child under running water in the bathtub.
  • Vomiting with diarrhea If your child has vomited more than twice, follow your doctor's recommended treatment for vomiting instead of this treatment for diarrhea until your child has gone 8 hours without vomiting.

When should I call my child's health care provider?

Call IMMEDIATELY if:
  • There are signs of dehydration (no urine in more than 12 hours, very dry mouth, no tears).
  • Any blood appears in the diarrhea.
  • The diarrhea is severe (more than 8 BMs in the last 8 hours).
  • The diarrhea is watery AND your child also vomits repeatedly.
  • Your child starts acting very sick.
Call during office hours if:
  • Mucus or pus appears in the BMs.
  • A fever lasts more than 3 days.
  • Mild diarrhea lasts more than 2 weeks.
  • You have other concerns or questions.
