👉 Zollinger-I bowls, also known as zollinger-Ellison disease, is an autoimmune disorder characterized by inflammation of the blood vessels in the small intestine. It primarily affects individuals with a genetic mutation that causes a protein called Zollinger-Ellison syndrome to be produced excessively. This abnormal production leads to inflammation and damage within the small intestine, causing symptoms such as abdominal pain, diarrhea, and weight loss.
