A bowel movement is the process of expelling waste from the digestive system through the rectum. This waste, known as feces, is composed of undigested food, bacteria, and other materials that the body no longer needs. Regular bowel movements are important for maintaining digestive health and can vary in frequency from person to person. Factors such as diet, hydration, and physical activity can influence bowel movement regularity. Foods high in fiber, like fruits and vegetables, can promote healthy digestion, while dehydration may lead to constipation. Understanding these factors can help individuals maintain a healthy digestive system.
