Thanks for your question on Health Care Magic. I can understand your concern. By your history and description, possibility of GERD (gastroesophageal reflux disease) is more. But better to get done ecg and 2d echo first, to rule out cardiac diseases. If both are normal then no need to worry for heart diseases. GERD can cause gaseous distention and bubbling feeling. It is due to laxity of gastroesophageal sphincter. So follow these steps for better symptomatic relief. 1. Avoid stress and tension. 2. Avoid hot and spicy food. Avoid junk food. Avoid large meals, instead take frequent small meals. 3. Start proton pump inhibitors and prokinetic drugs. 4. Go for walk after meals. Quit smoking and alcohol if you have these habits. 5. Loose weight if you are obese. Don t worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
