How long does it take to digest food?

How long it takes for the stomach to digest food depends on the patient's specific situation. Depending on the type of food the patient ingests, the time it takes for the stomach to digest food varies. When the patient's gastrointestinal function is normal, the stomach digests protein foods in about three hours, fatty foods in about four hours, and vegetables in about two hours. When the patient eats liquid food, the digestion time will be correspondingly shortened, which may be 2 to 3 hours.
