Thanks for posting your query.
Do you have acidic belching/ abdominal heaviness/ nausea
There may be possibility of gastritis
or may be migraine
along with gastric symptoms.
Sometimes migraine is also associated with gastric disturbances just like abdominal heaviness & vomiting.
You should consult with internal medicine specialist and should go for thorough check up.
You should also go for endoscopy
for better clarification.
You should also go for CT/ MRI scan imaging of brain.
Treatment depends on the diagnosed disease.
