How common is constipation in anal fissure?

An anal fissure is a small tear in the lining around the anus. Passing a hard or dry stool, straining, or delaying a bowel movement can stretch the area and cause sharp pain or bright red blood on the toilet paper. Pain may make someone hold back from opening their bowels, which can make stool harder and create a cycle of irritation. Constipation is common with anal fissure, but constipation by itself does not establish that a fissure is present.

Aim for softer, easier-to-pass stools by drinking fluids regularly, increasing fibre gradually, and moving your body as tolerated. Avoid forceful straining and respond to the urge to open your bowels. A pharmacist or clinician can advise on a suitable stool-softening treatment, especially if pain is making bowel movements difficult. Warm water soaks may ease discomfort, while persistent pain needs an examination.

Seek urgent help for heavy bleeding, black stools, severe abdominal pain, fever, vomiting, or fainting. Arrange a medical appointment if pain or bleeding keeps returning, symptoms do not settle, or you cannot pass stool or gas. Rectal bleeding has several possible causes and should not be self-diagnosed.
