K80-K87: Disorders of gallbladder, biliary tract and pancreas

The disorders of the gallbladder, biliary tract, and pancreas are a group of medical conditions typically involving disruptions or abnormalities in the digestion process. These can be due to a variety of issues, such as gallstones (hardened deposits within the fluids of the gallbladder), inflammation, infections, tumors, or structural problems within these organs. Symptoms often include abdominal pain, nausea, vomiting, jaundice (yellowing of the skin and eyes), and changes in stool and urine color. The disease progression varies widely, depending on the exact disorder and individual factors. For instance, gallstones may not cause any symptoms until they block the biliary tract, leading to acute pain and possible infection. Disorders in this group commonly disrupt the body's ability to process and absorb fats and other key nutrients, which can lead to a variety of health complications.
