Fat malabsorption
Fats that aren’t absorbed in your small intestine pass to your colon, causing fatty stools (steatorrhea). Fatty stools are greasy and runny and particularly smelly. They may be light-colored and float. Fat malabsorption also leads to the malabsorption of fat-soluble vitamins (A, D, E and K).

Why is food staying in my stomach so long?
A damaged vagus nerve can’t send signals normally to your stomach muscles. This may cause food to remain in your stomach longer, rather than move into your small intestine to be digested. The vagus nerve and its branches can be damaged by diseases, such as diabetes, or by surgery to the stomach or small intestine.
