There are many steps in the breakdown of food and movement of nutrients from gut to the rest of the body. The stomach and intestines need to be able to push food through the system. The stomach, liver and pancreas make fluids that help break down food. Once food is broken down, the nutrients can pass through the walls of intestine to the blood. Problems with any part of this process can cause malabsorption.
