A peptic ulcer is an area of tissue in your stomach, or in your small intestine in which the area has eroded. And there's actually a loss of the Mucosa of the tissue, which leads to what we call an ulcer, which is a small indentation, or it could be large indentation, which then can lead to bleeding, infection, and pain in patients. Not treating an officer can lead to very severe complications. If the officer gets large or deep and it erodes into a vessel that can large to a very life-threatening bleed, and if it gets even larger and it subsequently leads to a perforation or a hole in the bowel, it could lead to significant complications and even death.
