📚 Low-Residue Diet — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
A low-residue diet limits fiber and other foods that increase stool bulk to reduce the frequency and volume of bowel movements and rest the bowel. It is used in acute flares of inflammatory bowel disease, diverticulitis, bowel obstruction, and before and after bowel surgery. Less residue means less material reaching and irritating the colon.
🔑
Key points

Avoid whole grains, raw fruits and vegetables, nuts, seeds, beans, and tough meats.
Allowed foods include refined white bread, white rice, cooked tender vegetables, and lean tender meats.
Dairy is limited because it can increase residue and stool volume in some patients.
The diet reduces stool frequency and volume, giving the inflamed bowel rest.
It is the opposite of a high-fiber diet and is used during acute GI inflammation, not chronically.
