Perianal abscesses basically begin to heal at 7 days after surgery. You can eat staple foods and pasta, and be careful not to eat too greasy foods that may cause dry stools or constipation and make defecation difficult. You can eat fresh fruits and vegetables, but be careful not to make them too cold. You should also eat foods rich in vitamins and coarse fiber, including soy products, celery and carrots, which can replenish the nutrients needed by the body and help prevent dry stools. In addition, patients with perianal abscesses should drink more water after surgery, preferably honey water and drinks rich in vitamins, which can soften the stool and promote wound healing.
