If you have a bad stomach, you may have gastritis or gastric ulcer. Soda crackers are alkaline. If they are hard, it is recommended not to eat them. It may not be easy. Digestion will also increase the burden on the stomach. If it is a softer soda cracker, you can still eat it, no problem. People with weak stomachs should pay special attention to their daily diet. They should not eat raw, cold, spicy or hard foods that are difficult to digest. They should eat three meals a day on time, not stay up late, and rest on time.
