Where Does Undigested Fat Go?

Larger fat particles get absorbed by millions of tiny, fingerlike projections on the inside walls of the small intestine. Fats, or lipids, get repackaged and shuttled into the lymphatic system.

What happens when your body can't break down fat?

Diarrhea

“When the pancreas fails to produce the necessary digestive enzymes, fats and other nutrients can't be absorbed,” Agrawal explains. “Instead, they remain in the small bowel, drawing in water and causing diarrhea.”

When fat is absorbed where does it go?

The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins. Your liver produces bile that helps you digest fats and certain vitamins.
