"enema" 的定义和意义

What is an "enema"?

An enema is a medical procedure used to insert fluid into the rectum and colon through the anus. This is done to cleanse the bowel, give medication, or help in the diagnosis of certain medical conditions. Enemas typically involve inserting a small tube into the rectum and then slowly injecting the liquid solution. The liquid helps soften stool and stimulate bowel movements, providing relief from constipation or preparing for medical procedures like colonoscopy. Enemas are generally safe when performed correctly but should be used under medical supervision to avoid complications.
