Question: I have had three episodes of feeling like passing out in past 8 days...went to doctors ..many labs....the heart is fine,,,..I was found to have severe sleep apnea...I stop treating 33 times an hour....I have a Cpap I have used for 3 days now..... sleep is slightly improving form 3hrs -5hr=5hr and today 6 hour......Also I have been diagnosed with acid reflux...im taking pepcid ac, ..omeprazole been using for 10 days.....acid seems better.....Dr also thinks I have some anxiety in all this has prescribed buspirone 5mg.....Im not sure about the anxiety in this case I have had anxiety other instances.....were going to continue treatment for a few weeks and see how it goes......My question is the instances of me feeling short of breath and then feeling like I may pass out......that isn't something I recognize as my anxiety ( even though Medically I know it is) but I haven't experienced anxiety in that way in the past........to me I feel like my breathing itself is just not getting enough air into my system ....I do have asthma ( seasonally previously) but since the shortness of breath began I have been using albuterol 3 times a day..........Can severe sleep apnea and acid reflux do this to me ??? I feel maybe he has missed something ......maybe something with my lungs? Maybe acid reflux got into my lungs and damage them, can the acid in my stomach effect oxygen absorption in blood? I have never felt so short of breath before with a feeling of passing out all this is new to me........the feeling also comes and goes.....sometimes after a meal.....sometimes after activity like walking through a store or walking up a few flights of stairs.......when I feel the shortness of breath it also seems to come with a straining of the muscles in my neck and upper chest.........with a heavy pulling down feeling .....its quite an upsetting thing when it happens...any help would be appreciated! : )
