Diarrhea is a condition characterized by loose, watery stools that occur more frequently than normal.

Introduction

It can be caused by a variety of factors, including infections, food intolerances, medications, and underlying medical conditions.

The most common cause of diarrhea is a viral or bacterial infection. Viral infections such as norovirus, rotavirus, and adenovirus can cause diarrhea, as can bacterial infections like Salmonella, E. coli, and Campylobacter. Infections can be spread through contaminated food or water, as well as through close contact with someone who is infected.

Other common causes of diarrhea include lactose intolerance, celiac disease, inflammatory bowel disease, and irritable bowel syndrome. Certain medications, such as antibiotics, can also cause diarrhea as a side effect.

In most cases, diarrhea will resolve on its own within a few days. However, it is important to stay hydrated by drinking plenty of fluids, and in some cases, medication may be necessary to manage symptoms. If diarrhea persists for more than a few days or is accompanied by other symptoms such as severe abdominal pain, fever, or blood in the stool, it is important to seek medical attention.
