Fiber is scientifically validated for the support and treatment of hemorrhoids. Multiple randomized controlled trials and systematic reviews have demonstrated that increased dietary fiber intake is effective in relieving symptoms associated with hemorrhoids, such as bleeding, pain, and prolapse. The primary mechanism is that fiber increases stool bulk and softens stool, which facilitates easier and less painful defecation, reducing straining and subsequently lowering venous pressure in the hemorrhoidal plexus. This, in turn, helps to minimize the exacerbation of hemorrhoidal symptoms and can prevent recurrence.

A landmark systematic review published in the "American Journal of Gastroenterology" (Alonso-Coello et al., 2006) analyzed several randomized controlled trials and concluded that fiber supplementation resulted in a significant reduction in the risk of persistent symptoms and bleeding compared to placebo. The review suggested that fiber can decrease the risk of persisting symptoms by approximately 50%. Most clinical guidelines, including those from the American Society of Colon and Rectal Surgeons, recommend fiber as a first-line intervention for both prevention and management of hemorrhoids.

In summary, the use of fiber in hemorrhoid management is backed by robust scientific evidence, making it a cornerstone of conservative therapy for this condition.
