Excessive gas post meal, Acidity b4 meal

Healthy and no other conditions except for Vitamin D level of 5.5. The problem started when I skipped my meals or not eating healthy and irregular timings in lockdown. It started with a feeling of emptiness (as if there is cold air stuck in the area where we usually feel acidity heartburn). Even after meals, I felt as if something empty inside (similar to when hungry). However there was no acidity pain or obvious gas symptoms. 2-3 weeks later, I started experiencing mild heartburn mostly when empty stomach, and 45-60 mins post meals, I get excessive gas (bloating mostly) which will last 2-3 hours. There was also slight shortness of breath especially in semi-lying position (e.g. slouching in couch), not sure if that's related to this, as it goes away in 3-4 days. After 2 days of above gas symptoms, I started Ranidom (Omeprazole 10 and Domperidone 15), for around 60 days now. Its helping the symptoms. Should I continue this (how long?) or anything serious to go for check up ? Thanks!
