For individuals experiencing gut inflammation, consuming fiber can exacerbate symptoms like bloating and gas, according to gut and hormonal coach Davida Syne and gastroenterologist Dr. Saiprasad Girish Lad. They explain that when the gut lining is irritated and motility is slow, indigestible fiber ferments, causing discomfort. The advice is to stabilize the gut first before reintroducing fiber, as it can feel like sandpaper on an open wound for those with sensitive digestive systems.
