@n0tdrew- Hello. Welcome to Mayo Clinic Connect. As you can see by the size of this discussion group you are amongst people just like you who have the same problems with taking a deep breath, and out of the clear blue too! When we inhale we think that it's a given that we can fill our lungs up and when we can't it's very scary. And on top of that, you are told not to worry about a finding in your lung. There are several things that I see going on. First, GG (ground glass) shows up on CT scans. It can indicate so many different things. I don't blame you for still being scared. In my opinion, you should have a follow-up scheduled in 3 months to see if it goes away or if it grows. If you have a history of smoking or around cigarette smoke, or any strong chemicals that could be the cause.

Do you have a history of smoking or being around people who do smoke or around strong chemicals?

Do you exercise a lot? Sometimes exercising can induce what is called exercise-induced asthma. I would also advise you to get a copy of all of your blood work, breathing tests, radiologist reports from your CT scans, and any other test results. You are entitled to them. Then have the results explained to you, in full.

There are reasons for gas build-up can be many things. You might be gulping your food now, even without realizing it. You might have cut back on your activities because of your fear. In order to get rid of gas, we need to move! Bloating and difficulty breathing can occur in a cycle: Bloating can increase pressure on the lungs, making it harder to breathe. Then, this difficulty breathing can cause you to feel bloated, or make your bloating worse. If you are feeling breathless, you may be more likely to take small, short breaths, which causes you to swallow more air. Swallowing air (known as aerophagia) can cause bloating

New medications can also cause you to bloat, especially narcotics but inhalers are known to do this too. Let me suggest keeping a journal of when you feel bloated. By writing down your symptoms, you may be able to determine what factors (inactivity, difficulty breathing, medications, or diet) are causing your bloating.

Do you think that you might seek another Pulmonologist?
