Psyllium fiber is commonly used to support the management of hemorrhoids, and its use is supported by scientific evidence. Hemorrhoids are swollen veins in the lower rectum or anus, frequently associated with straining during bowel movements and constipation. Psyllium is a soluble fiber that absorbs water, forming a gel-like substance in the gut, which softens stool and increases its bulk. This promotes easier and more regular bowel movements, reducing the need for straining, which is a key factor in both the development and exacerbation of hemorrhoids.

Several clinical guidelines, including those from gastroenterological societies, recommend increased dietary fiber intake, often specifically mentioning psyllium, as a first-line conservative treatment for symptomatic hemorrhoids. Randomized controlled trials have shown that psyllium supplementation can improve symptoms such as bleeding and discomfort by softening stools and normalizing bowel habits. A systematic review published in the American Journal of Gastroenterology (2005) concluded that fiber supplementation led to significant improvement in overall symptoms and reduced the risk of persisting symptoms and bleeding.

While psyllium does not treat the hemorrhoids themselves, it addresses one of the main aggravating factors—constipation and hard stools—making it a scientifically validated supportive measure in the conservative management of hemorrhoids.
