Perianal redness and swollen meatballs may be related to hemorrhoids, rectal polyps and other causes. 1. Hemorrhoids: for example, overeating, prolonged standing and sitting, overwork and other reasons can lead to varicose veins in the lower rectum or mucous membranes around the anal canal, which can lead to the formation of hemorrhoids. If these veins are located outside the anus, it can lead to a soft ball of flesh felt at the anus. 2. Rectal polyps: When a single rectal polyp of small diameter is present, it may not result in a red, swollen ball of flesh around the anus. However, if a single rectal polyp is large in diameter, it can lead to increased abdominal pressure, which can cause the rectal polyp to prolapse out of the anus, where a red, swollen ball of meat may form. 3. Other: including anal papilloma out of the anus, rectal mucosal prolapse, perianal abscess, etc., can lead to red swollen meatballs in the perianal area. When the perianal red meatballs appear, it is recommended to go to the hospital in time for examination, to clarify the cause of the disease, targeted treatment, so as not to delay the condition.
