Shortness of breath at night is a sign of what disease?

Question
Hello doctor,
Two months ago, I was diagnosed with gastroesophageal reflux with symptoms of shortness of breath, indigestion, and bloating easily. I have taken a pack of gaviscon and found it much better. On the evening of July 12, 2021, I had difficulty breathing from 11 am to 2 am before I could sleep, this time it was the worst and longest. This time is a bit sensitive, I have no fever, no cough, no chest tightness, no loss of taste. The doctor asked me, what is the sign of trouble breathing at night? Should I get tested for covid or go to a regular doctor?
