There are three lumps of flesh in the anus, which become bigger only when squatting, and such symptoms may be internal hemorrhoids, external hemorrhoids, anal fissure, etc. 1. internal hemorrhoids: if the patient’s internal hemorrhoids hemorrhoid nucleus grows larger, will prolapse outside the anus, in the squatting, due to gravity and abdominal pressure increases, will stimulate the hemorrhoid nucleus, resulting in hemorrhoids nucleus enlargement, at this time it is very difficult to automatically retrieve the anus. 2. External hemorrhoids: three lumps of flesh may be small meatballs of external hemorrhoids, generally varying in size, in the shape of a meatball or oval shape. Gravity causes the meatballs to become larger when squatting. 3. Anal fissure: if the patient has anal fissure, anal fissure is serious, it will lead to multiple muscle tissue cracks on the outside of the anus, multiple fracture surfaces, forming multiple meatballs. It will be accompanied by obvious stinging sensation as well as bleeding in the stool and other symptoms. When three meatballs appear in the anus and become bigger when squatting, the patient should go to the anorectal department of the hospital in time to do a systematic examination, make a clear diagnosis, and give treatment as soon as possible to avoid aggravation of the symptoms and cause adverse consequences.
