Patients with proctitis can eat garlic, but they should also avoid consuming large amounts of garlic, as excessive garlic can easily irritate the rectum and exacerbate the inflammation. It is recommended that patients with proctitis eat foods that are easy to digest and non-irritating, such as white rice porridge and millet porridge. They should avoid spicy, irritating, and greasy foods. It is also necessary to quit smoking and drinking, and to avoid strong tea and coffee as much as possible. Patients with proctitis can take oral medications to regulate the intestinal flora for treatment; the choice of specific medications should be based on the doctor's clinical experience.
