I do appreciate your comments.
Hi
Welcome to the forum!
Fullness in the right side of the abdomen can be due to IBS. There are no tests for IBS. Diagnosis is generally by history, symptoms and elimination of other causes like gluten intolerance or Crohn’s disease or lactose intolerance.
Chances are also that you have esophageal reflux (GERD), where the food in your stomach is thrown up into your food pipe or esophagus. Another possibility is hiatal hernia, where a portion of stomach herniates into the chest cavity through the diaphragm. Both can cause a discomfort in the chest area, burning, heaviness etc.
It is difficult to comment beyond this at this stage. Please consult a GI doctor or gastroenterologist.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
