Thanks for posting your query.
Gall stones may be asymptomatic or symptomatic. Asymptomatic gall stones
doesn't need any treatment except it has risk of causing gall bladder cancer
Symptoms due to gall stones may be pain (in right upper abdomen), nausea
Burping with nausea indicates dyspepsia
and it has no correlation with gall stones.
You should consult with physician and also go for endosocpy to rule out gastric problems.
