1. Abdominal pain: Common pancreatic diseases, such as chronic pancreatitis, acute pancreatitis, and pancreatic cancer, can cause abdominal pain. Acute pancreatitis causes severe pain that can radiate to the back. 

2. Jaundice: Pancreatic diseases often present with jaundice. Pathological changes in the pancreas can compress the bile duct, obstructing bile excretion and causing jaundice.

3. Constipation: Early stages of pancreatic disease may lead to intestinal paralysis, and severe cases can cause colonic paralysis and dilation, resulting in symptoms like bloating, constipation, reduced flatulence, and abnormal bowel sounds. 

4. Body wasting: The pancreas plays a role in digestion and absorption.

Pathology in the pancreas affects the digestive system's health, leading to inadequate digestion and absorption of nutrients, resulting in body wasting.
