I m a 50 year old male, 5 10 , 195, so overweight, but not obese. I ve been checked out by my family doctor and gastro who performed an endoscopy all yielding no answers. I have frequent burping starting as soon as I get out of bed and when sitting, my stomach feels like it s pressing on my lungs and I want to take deep breaths, but sometimes can t complete them. Irritating and uncomfortable, but people have worse to deal with. Thoughts?
