Towards the end of the digestive process, our stool passes through the anal canal, ultimately making its exit from the anus. The anal canal is a small tube at the end of the rectum. Occasionally, anal fissures – meaning small tears – may develop in the anal canal. Anal fissures are a common condition and are mostly harmless. However, in certain circumstances, anal fissures may cause severe pain and irritation. Find out ten causes and symptoms of anal fissures.
The friction caused by stool as it leaves the rectum can cause anal fissures to appear. You'll usually feel a sharp and sudden pain around your anus. Irritation can extend all the way inside the rectum. Hard stool can form for many reasons, but dehydration is often the main culprit. As food travels through the digestive system, it needs water to keep it moist. If you don't consume water, the stool will harden, which may also cause constipation. You may even notice blood as you wipe.
