Hello, Thanks for using healthcaremagic. Actually gastrointestinal(GI) system is controlled by brain and when nervous system effected for any reason , it also makes effects on gastrointestinal system like acidity.Sometime things occur vice-a-versa. So what happened first!, either anxiety or acidity that matters. In your case acidity started due to stress and anxiety. You have treated for anxiety but when you had suffering, your GI system was modualted in the way that you can not take spicy or sour food. If your anxiety is still there primary treatment of that must be done. However if you do not have anxiety you can initially take anti acidity medicines like pentoprazole, rabeprazole or ranitidine before having such food. You can introduce less spicy food initially and then increase spiciness of food as you tolerate lesser one.So you can gradually adapt to that food which you were able to take before anxiety.And later on you can stop anti acidity medicines. Hope, you have got my point. Regards, Dr.Chintan Solanki.
