What defines diarrhea?

Diarrhea is defined as the passage of loose, watery stools three or more times a day. It can be caused by a variety of factors, including infection, inflammation, and malabsorption. Diarrhea can also be a symptom of certain medical conditions, such as irritable bowel syndrome (IBS) and Crohn's disease.

Diarrhea can be classified as either acute or chronic. Acute diarrhea is defined as diarrhea that lasts for less than two weeks, while chronic diarrhea is defined as diarrhea that lasts for two weeks or more. Acute diarrhea is most often caused by infection, while chronic diarrhea can be caused by a variety of factors, including infection, inflammation, and malabsorption.

Diarrhea can lead to a number of complications, including dehydration, electrolyte imbalances, and malnutrition. Dehydration occurs when the body loses more water than it takes in. Electrolyte imbalances occur when the levels of electrolytes, such as sodium and potassium, in the body are too high or too low. Malnutrition occurs when the body does not get enough nutrients from food.

Treatment for diarrhea depends on the cause. In most cases, acute diarrhea will resolve on its own within a few days. Treatment for chronic diarrhea may include medications, diet changes, and lifestyle modifications.
