Diarrhea describes loose, watery stools that occur more frequently than usual. Diarrhea is something everyone experiences. Diarrhea often means more-frequent trips to the toilet and a greater volume of stool.
In most cases, diarrhea signs and symptoms usually last a couple of days. But sometimes diarrhea can last for weeks. In these situations, diarrhea can be a sign of a serious disorder, such as inflammatory bowel disease, or a less serious condition, such as irritable bowel syndrome.
Colon and small intestine
The small intestine and colon are components of your digestive tract, which processes the foods you eat. The small intestine and colon extract nutrients and water from the foods. What isn't absorbed ...

Diarrhea occurs when the food and fluids you ingest pass too quickly or in too large an amount — or both — through your colon. Normally, your colon absorbs liquids from the food you eat, leaving a semisolid stool. But if the liquids from the foods you eat aren't absorbed, the result is a watery bowel movement.
A number of diseases and conditions can cause diarrhea. Common causes of diarrhea include:
Preparing for your appointment
Start by seeing your family doctor or a general practitioner if you have any signs or symptoms that worry you. If you have persistent diarrhea, your doctor may refer you to a doctor who specializes in the digestive system (gastroenterologist).

Treatments and drugs
Most cases of diarrhea clear on their own within a couple of days without treatment. If you've tried lifestyle changes and home remedies for diarrhea without success, your doctor may recommend medications or other treatments.
Treatment to replace fluids

Disruption of your body's fluid and mineral levels creates an electrolyte imbalance that can be serious. You can help maintain your electrolyte levels by drinking fruit juices for potassium or eating soups for sodium.
