Can gastritis cause breathing issues?

This all started 2 months ago when I was drinking some diet coke from a glass and a small piece of ice went in my throat and my throat spasmed up.2 days later i went to the ER and they did a throat xray and nothing there. Doctor gave me omeprazole. Don't know why. A week later i had an endoscopy and I was diagnosed with chronic gastritis. Normal esophagis. No h. pylori. I have a diminutive hiatus hernia but the surgeon i met with said thats hardly a hernia if one at all looking at the picture. My main symtom is breathing problems. Hard to fully exhale due to being bloated 24/7. It has been this way the whole time with zero letup. I have taken omeprazole, esomaprazole, and i am currently taking lansoprazole 30mg. My question is do you think the breathlessness is caused by the gastritis or a side affect of the PPI's or something else? Thanks and by the way im in the USA.

Gastritis can take a while to heal, and the medication takes a while to kick in. I would try to adhere to a GERD-friendly diet that would help with the symptoms of your gastritis and also take some anti-gas medication (simethicone), to help with the bloating. Also, try and stay away from NSAIDs such as Advil and Aleve, as they will make your gastritis worse. To ease your mind, you might want to schedule an appointment with a pulmonary specialist who can test your breathing function to rule any other issues out. Sometimes a quick onset of a medical condition is coupled with anxiety over the situation and that might cause/make the other symptoms seem worse. Also, make sure you are taking the PPIs properly - you need to wait about 30 minutes after, then you must eat.
