It is important to find out the possible cause
for gastritis - allergy to foods? Celiac
? And to eliminate foods that cause
ample acid production - milk, tomato based foods, vinegar, chocolate and other caffiene - just to name a few.
Try to stick to low fat foods, rice, beans, fruits, vegetables, lean meats and fish, no spicy and little spice.
Gastritis can cause
a shortness of breath. I find that when I'm full of gas/air and I'm constantly burping, my breathing is more difficult.
