Undigested food in stools can have various causes, just like most other symptoms. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose undigested food in stools, we could:
lactose intolerance
nausea for 1-3 months
fatty food intolerance
heavily coated tongue
upper abdomen pain after fatty meals
occasional unexplained nausea
regular meal-related burping
reduced desire to eat breakfast
vegan diet
brittle fingernails
iron deficiency anemia
severe flatulence|
