Hello Good Evening, This seems to be peptic (gastric or duodenal) ulcers, which may cause burning, nausea or even vomiting. Peptic ulcers can cause pain and burning constantly, which may reduce by eating something, so you have an irrational need to eat. You should go for a UGI endoscopy to rule out peptic ulcers. You are also suffered from bloating, which may cause constipation due to decreased bowel movements and constipation may also caused bloating. There are many causes of bloating, including: diet, irritable bowel syndrome, lactose intolerance, re flux, and constipation and some more. Gas and bloating is a sign that food is not being digested correctly by the body. An inadequate intake of water will cause excessive stomach bloating. Water benefits the body by aiding with digestion because it supports a majority of the body s daily functions. Fatty foods cause a formation of fat cells to develop throughout the body and contribute to bloating as well. A build up of fat cells slows down the body s ability to empty the stomach. Dairy products also contribute to excessive cramps, gas, and bloating. Persons who are intolerant to lactose products experience this effect more than others. Following steps should follows to lessen the bloating: -Walk after eating a meal. -Exercise -Avoid coffee and chocolates. -Avoid Meals that are high in fat. -Avoid extremely hot or cold food. -Avoid bubble gum or bubbly beverages. -Avoid alcohol and smoking If needed then medication should be included antacids, PPI, digestive enzymes and some laxatives.
