Can hemorrhoids lead to the development of thin stools?

Hemorrhoids are swollen veins in the lower part of the rectum or anus. They can cause discomfort, itching, and sometimes bleeding. However, they are not known to cause changes in stool shape, such as making stools thin or pencil-like.

According to the provided references, thin stools are not a common symptom of hemorrhoids. One study discusses bowel habits in hemorrhoid patients, but it does not link hemorrhoids to thin stools. Another reference specifically notes that 'low caliber stool' or 'pencil thin stool' are not signs of hemorrhoids. This means that if someone is experiencing thin stools, it may not be due to hemorrhoids and could be related to other factors or conditions.

If you are concerned about changes in your bowel habits or stool shape, it is important to talk to a healthcare professional for proper evaluation and advice.
