Your pancreas is a long gland next to your stomach. It makes gut juices that help you digest your food. If it gets inflamed, you have what’s called “pancreatitis.” Besides burping, you may vomit, feel bloated, get the hiccups, or run a fever. If you suspect you have pancreatitis, see your doctor. A mild case could clear up on its own. In a severe case, you’ll likely need to stay in a hospital and get fluids and nutrition by IV while your gut rests.
