Wheat bran is supported by scientific evidence for use in managing hemorrhoids, primarily due to its high insoluble fiber content. Dietary fiber increases stool bulk and softens stool, making bowel movements easier and reducing straining—one of the primary risk factors for the development and worsening of hemorrhoids. Multiple randomized controlled trials and clinical guidelines (such as those from the American Society of Colon and Rectal Surgeons) recommend fiber supplementation, including wheat bran, as first-line therapy for hemorrhoids. For example, a double-blind trial by Misra et al. (1981) demonstrated that patients with hemorrhoids who supplemented with wheat bran experienced significant symptom improvement, including reduced bleeding and discomfort, compared to placebo. Systematic reviews have concluded that fiber supplementation decreases the risk of persistent symptoms and recurrence in patients with symptomatic hemorrhoids.

Wheat bran is often specifically mentioned in clinical texts due to its well-tolerated, cost-effective, and widely available nature. While fiber does not treat hemorrhoids directly, it addresses one of the underlying causes—constipation and hard stools—thus significantly reducing symptoms and improving quality of life in most sufferers. The evidence base is robust, though not all patients will respond equally. Overall, the use of wheat bran for hemorrhoid support is scientifically sound and widely recommended by healthcare professionals.
