Hi, symptoms are due to mild gastritis. If gas is a problem for you, foods that might make symptoms worse include beans, cabbage, cauliflower and broccoli. Fatty foods also may be a problem for some people. Chewing gum or drinking through a straw can lead to swallowing air, causing more gas. Eat at regular times. Don't skip meals, and try to eat about the same time each day to help regulate bowel function.
