Thanks for answering my questions.
Ans to your question-Now looking at from what you mentioned,age,symptoms,there is a possibility that your symptoms could be due to underline lung
pathology so ask your physician to check your pulse oximetry while sitting and after some exercise.If it desaturates then he will have to do a xray of chest and pulmonary function tests to rule out possible causes.
Other possibility could be undiagnosed central sleep apnea as it may also present with similar symptoms like yours,so you might have to ask the physician to do sleep study test to confirm this diagnosis.
Other possibility causing your symptoms could be underline undiagnosed arrhythmia or any heart condition(aortic stenosis) may sometimes presents with intermittent shortness of breath so ask your physician to do EKG to rule this possibility.
Sometimes low thyroid
hormone also can lead to carbon-di oxide retention and that may also make a person gasp for breath so ask your physician to do serum TSH to rule this possibility too.
Other possibility could be underline anemia which also can lead to similar symptoms so ask your physician to do complete blood count to rule it out.
