Question) My stomach keeps feeling bloated… Is it because of gas?

Lately, I have been feeling uncomfortable because my stomach constantly feels bloated. Even though I haven't eaten much, my stomach feels heavy and distended immediately after meals, as if it is filled with gas. It doesn't go down easily even after some time, so it bothers me during my daily life.

I am wondering if this is simply due to gas, or if it is related to poor digestion or gut health. I suspect it might be due to my recent eating habits, and I am also worried that stress or my lifestyle patterns might be having an impact.

I am wondering if taking probiotics or changing my eating habits could help, and I would also like to know if it would be a good idea to visit a hospital for a checkup if these symptoms persist. If anyone has had a similar experience, please give me some advice.
