[|AI|]  Thanks for your question on Chat Doctor. In my opinion may have diabetic osteopathy. It is problem of autonomic nervous supply of stomach. Because of long-standing diabetes, microvascular complications can occur in the form of autonomic dysfunction. So gastric nerves can be affected, and can cause problem. So your pain behind lower sternum can Be due to this. Gastritis can also be seen in diabetic osteopathy. So try to follow these steps for better symptomatic relief.1. Strict control of diabetes is needed.2. Avoid oily and spicy food. Avoid large meals, instead take frequent meals.3. Avoid stress and anxiety.4. Take proton pump inhibitor.5. Go for walk after meals.
