Chronic Khat Chewing Induced High-Grade Hemorrhoidal Disease and Post-Operative Bleeding in Yemen

Chronic khat chewing is strongly associated with high-grade hemorrhoidal disease and increased post-operative complications. Mechanisms include chronic constipation, increased anal sphincter tone, and prolonged sitting. These findings highlight the need for public health strategies to reduce khat use and tailored clinical approaches to improve outcomes. Future research should focus on establishing causality, identifying confounders, dose-response relationships, and exploring gender-specific management strategies that target both mechanical and pharmacological factors to optimize surgical care and long-term outcomes.
