Stomach fullness (Dyspepsia) I do?

Hello , myself 40 years old male having only stomach fullness and burping for last 3 months on and off. It happens after every 5-7 days and subsides after taking PPI for 1-2 days.But for last 14 days I m having this problem frequently . Earlier I had stomach burning sensation for 3 months on and off since January 2024 till April 24 which was subsided after taking 1 month PPI as given by Dr. In April 24 i underwent Lap. Cholecystectomy for GB Polyp and I didn't have any post op problem. But Since August I use to have stomach fullness on and off till now. Other than that no other symptoms. no weight loss , no pain, stool colour normal, sometimes constipation. What might be the cause? Is it cholecystectomy related or there is any major issue to concern? Please suggest the treatment and what should I do?
