stomach gastritis dizzy\giddy\head heavy

whenever i have my meals i, my head becomes heavy, sometimes there is dizzyness or giddiness and i am unable to go for a walk. if i have tea my neck becomes stiff immediately with head becoming heavy. there is burping which gives me temporary relief. there is no stomach pain \ inflammation etc. my endoscopy result showed no ulcer. the diagnosis was antral gastritis. i was given pentaprozole by doctor but things have not improved. bowel movements are satisfactiry and my food intake is also good. no loss in wieght,

if i do not take food for long or my stomach is empty then also i get a giddy\dizzy feeling and my stomach becomes stiff. i have no sugar problem as fasting sugar tests are all fine.

kindly suggest a remedy for which i will be greatful to you

You may want to consider looking into the possibility of celiac disease as that condition can result in the types of symptoms you're describing.
