Why does bacterial fermentation increase gas production after a patient undergoes a partial small bowel resection?

💡 Explanation

The increased gas production following small bowel resection occurs because unabsorbed carbohydrates reach the colon, where they are fermented by bacteria, producing gas. The digestion is incomplete, therefore fermentation increases, rather than other absorptive or motility defects being the primary cause.
