Hello I'm a 38 year old male. 5 months ago I went for an upper GI because I was burping excessively, and had a nerve pit (butterfly feeling) in my stomach. The results were gastritis, and I was given Nexium to help control the symptoms. I was okay for a bit, and now the problem is back again. I have been eating properly (no fried foods), and slowly losing weight (I’m about 40 lbs. over weight). I’ve noticed when I have this feeling in my stomach, my breathing is affected. I have to take a deep inhale to get a full breath. Can gastritis affect breathing?
