I feel that your symptoms are most likely due to GERD(gastroesophageal reflux disease
) : same thing you suspected acid reflux
. I would suggest you take a proton pump
inhibitor like pantoprazole
once a day in the morning half an hour before breakfast for a week. Stop mylanta, gas x, pepcid. Continue the medications you take to control diabetes
.Normally proton pump inhibitors are tried for at least a month. What you could do, is give a trial for one week with proton pump inhibitor and if your doctor refers you to a GI doctor, they might advise you to get an endoscopy
done to rule out any other pathology. Have you got your thyroid function evaluated?
Meanwhile, do not lift heavy weights immediately after a meal. Do not take a bath immediately after a meal.Do not sleep or lie down immediately after a meal.After having a meal, rest in a sitting position for 15 min followed by walking leisurely for another 20 min. Even at dinner, sleep only after 2 hours of having a meal. While sleeping ,keep your head end elevated. Avoid fatty, deep fried, spicy food. Avoid tea, coffee, and other carbonated beverages.
Hope this helps.Have a nice day :)
