Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, we should rule out
obstructive sleep apnea (OSA) and bronchitis in your case.
You are overweight and having choking history. So OSA is likely.
Breathing difficulty is commonly seen with bronchitis.
So better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. PFT (pulmonary function test) for bronchitis
3. Sleep study for OSA.
You may need inhaled
bronchodilator and inhaled
corticosteroids for bronchitis.
For OSA, you will have to loose weight and start CPAP (continuous
positive Airway Pressure) machine at night in sleep.
Don't worry, you will be alright.
First diagnose yourself and then start appropriate treatment.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
