Error: This is required. Error: Not a valid value. The anus is made up of the last few centimetres of the bowel anal canal and the anal opening, through which stool poo or faeces leave your body. During a bowel movement, the anal muscles the sphincters relax to release stool. It can be distressing when there are problems with anal functions. Diet, digestion, sexual activity and genetic and environmental factors all play a role in anal health.

The anus is the opening at the end of your anal canal. The rectum sits between your colon and anus and acts as a holding chamber for stool. When pressure in your rectum becomes too great, the internal ring of muscle called the anal sphincter relaxes to allow stool to pass through your anal canal, the anus, and out of your body. The anus consists of glands, ducts, blood vessels, mucus, tissues, and nerve endings that can be highly sensitive to pain, irritation, and other sensations.
