Once the anus is torn, it is difficult to heal: defecation every day, tearing every day.
Prevention of dry stool first of all: fast and spicy food that is easy to get angry in the near future. Every meal should be accompanied by fresh fruit juice, vegetable juice, yogurt and other foods and drinks that nourish intestinal flora.
Don't use force at the beginning of defecation, and try to excrete naturally. After the hard part is discharged, the soft part comes out.
Rinsing with warm water after defecation is beneficial to wound healing.
