Weight Loss question involving gas (Urgent)

Patient: I recently started losing weight and I’m passing gas a lot. It doesn’t smell and I can feel a bit of discomfort at just above my navel then it finally releases through my anus. I also started burping somewhat often in the past few minutes of writing this. Is this a good or bad thing and why is this happening?

Symptoms: Constant passing of gas and burping.

Doctor:
