What are the primary causes of thin stools?

Thin stools, sometimes called "pencil thin stools," can be linked to different bowel issues. According to the references provided, bowel dysfunction is a common cause of thin stools. For example, people with fibromyalgia may experience bowel problems, which can lead to changes in stool shape and size.

Additionally, individuals with hemorrhoids may also notice changes in their bowel habits, including the presence of thin stools. Hemorrhoids can cause discomfort and may alter normal bowel movement patterns.

It's important to note that thin stools are not necessarily a sign of a serious condition, but they can indicate changes in bowel habits that may need attention. If you have concerns about your bowel movements, it's a good idea to speak with a healthcare professional for further advice.
