Coarse stools are considered to be due to excessive meat eating, insufficient fiber intake in the diet or drinking too little water, resulting in dry stools, difficult defecation and constipation, which may also be related to insufficient gastrointestinal power and may easily lead to anal fissure bleeding. It is recommended to pay attention to adjust the diet structure and eat more fresh vegetables and fruits rich in dietary fiber, such as celery, bamboo shoots, leeks, bananas, apples, kiwis, etc. Eat more coarse grains and miscellaneous grains, avoid eating too much meat, and avoid spicy and stimulating foods. Drink more water, drink a glass of honey water or sugar salt water every day on an empty stomach to promote gastrointestinal peristalsis and bowel movement. Drink a glass of yogurt every day to help maintain the balance of intestinal flora and develop the habit of regular daily bowel movements.
