The main reason why lying-in women are prone to anal fissure is diet. High-quality diet is easy to cause constipation. Some pregnant women still eat hot food such as mutton and ginger soup, but they don't eat fruits and vegetables or seldom eat them. In addition, the lying-in woman is in bed with little activity, which slows down the intestinal peristalsis, the stool stays in the intestine for too long, the water is absorbed and too dry, it is difficult to defecate, anal fissure occurs, and anal pain and even bleeding occur during defecation. During this period, it is necessary to change the diet structure, eat more fresh vegetables and fruits to increase the amount of stool, eat more fish soup and pettitoes soup to lubricate the intestines and replenish enough water.
