Final answer:
Diarrhea is a condition characterized by rapid movement of fecal matter through the intestines, resulting in frequent loose stools. It can be caused by various factors including diet, health, and the ingestion of foodborne pathogens. Seeking medical attention is important if diarrhea persists or is severe.
Step-by-step explanation:
Diarrhea is a condition in which there is rapid movement of fecal matter through the intestine, resulting in abnormally frequent evacuation of watery feces. This happens when the waste matter moves too quickly through the intestines, not allowing enough time for water to be absorbed, resulting in loose stools.
The frequency of bowel movements is influenced by various factors including diet, health, and stress. It can vary greatly between individuals, ranging from two or three per day to three or four per week.
Common causes of diarrhea can include the ingestion of foodborne pathogens, such as bacteria that affect the proteins involved in water reabsorption in the colon. It is important to stay hydrated and seek medical attention if diarrhea persists or is accompanied by severe symptoms.
