Digestive Diseases
The digestive system made up of the gastrointestinal tract (GI), liver, pancreas, and gallbladder helps the body digest food. Digestion is important for breaking down food into nutrients, which your body uses for energy, growth, and cell repair.
Some digestive diseases and conditions are acute, lasting only a short time, while others are chronic, or long-lasting.
