Disorders of digestive system

In indigestion the food is not properly digested, leading to a feeling of fullness.
Its causes include anxiety, food poisoning, over-eating, spicy food and inadequate enzyme secretion.

The liver is the largest digestive gland; it secretes bile, which contains the bile pigments bilirubin and biliverdin.
In jaundice the liver is affected (or the bile duct is blocked), so the bile pigments accumulate in the blood and are deposited in the tissues.
The skin and eyes turn yellow as a result; this is only the visible symptom, not the seat of the disorder.
NCERT lists jaundice among the disorders of the digestive system.
Hence jaundice is a disorder of the digestive system.
