If the skin around the stoma breaks down, stoma solution and stoma powder need to be applied promptly. If left untreated, this may lead to infection due to contamination of the skin with intestinal fluid and feces, and sometimes to dermatitis, which can be painful for the patient. If there is already mild localized redness and swelling, zinc oxide ointment or petroleum jelly ointment can be applied, which can protect the skin around the stoma and also act as an astringent. At the same time, during the period of skin breakdown, the diet should be adjusted so that the stool is not too dilute. You can properly consume more vitamin-rich green vegetables and vitamin-rich fruits, such as spinach, cabbage, kiwi, apple, banana and duck pear, etc. Do not eat too greasy food, such as red meat, etc., which can easily lead to diarrhea and cause the contamination of the skin by stool. Hospital surgery or stoma clinic for consultation and treatment.
