What does SIBO bloating feel like?

SIBO bloating is often described as an intense, tight, and uncomfortable distension that can make the abdomen look visibly swollen or even "pregnant." Unlike normal post-meal fullness, this distinct bloating typically begins 30 to 90 minutes after eating, even after consuming seemingly healthy foods like broccoli, apples, or garlic. It is frequently accompanied by a heavy sense of abdominal pressure, excessive gas, loud gurgling, and physical discomfort as the misplaced bacteria rapidly ferment dietary carbohydrates, releasing hydrogen or methane gases. This fermentation process creates trapped gas pockets in the narrow small intestine, causing the abdominal wall to stretch painfully.
