Diseases that affect the pancreas, liver, kidneys, adrenal glands, or other organs. 2. Metabolism problems that run in families. 3. Drinking too much of alcohol. 4. Malnutrition. Thus you need go undergo further evaluation to rule out these by complete physical examination and investigations like 1.
