Can Constipation Cause Blood in Stool?

Yes, constipation can sometimes cause blood in the stool. There are a few reasons why constipation may lead to the presence of blood in the stool:

  1. Straining during bowel movements: When you’re constipated, passing stool can become difficult and require straining. Straining puts increased pressure on the blood vessels in and around the rectum, which can lead to the development of small tears or fissures in the anal canal. These fissures may cause bleeding, resulting in blood in the stool.
  2. Hemorrhoids: Constipation can contribute to the development or worsening of hemorrhoids. Hemorrhoids are swollen and inflamed blood vessels in the rectal and anal area. Straining during bowel movements due to constipation can exacerbate hemorrhoids, leading to bleeding.
  3. Anal Fissures: Chronic constipation can lead to the formation of anal fissures, which are small tears in the lining of the anus. These fissures can cause pain and bleeding during bowel movements.

It’s important to note that while constipation can cause blood in the stool, there are other potential causes of rectal bleeding that may require medical attention. These include:

If you notice blood in your stool or have any concerns about changes in bowel movements, it’s crucial to seek medical evaluation. A healthcare professional can help determine the cause of the bleeding and recommend appropriate treatment or further investigations if necessary.

Remember that rectal bleeding should not be ignored, and it’s always best to get it properly evaluated by a healthcare provider to rule out any serious underlying conditions.
