Which is a contributing factor to stoma stenosis?

• A. Stomal necrosis
• B. Regular exercise
• C. High-fiber diet
• D. Adequate hydration

Answer: (A)

Stoma stenosis happens when scar tissue and contracture form as the stoma heals, narrowing the opening. If the stoma suffers necrosis, meaning tissue dies from poor blood supply, the healing process can become more fibrotic and constrictive, leading to a narrowed lumen. This is why stomal necrosis is a contributing factor. Other options do not directly cause stenosis: regular exercise doesn’t alter the stoma diameter, a high-fiber diet mainly affects stool form and transit rather than the stoma opening, and adequate hydration supports tissue health rather than causing narrowing. The key idea is that tissue death and the subsequent fibrotic healing process tighten the stoma.
