Thanks for the query to H.C.M. Forum.
I would come up with these possibilities for this type of symptoms, these includes.
1 The first possibility is of peptic ulcer disease
or Hyper acidity . Diagnosis can be confirmed by upper G I endoscopy
. As bloating
, burping, gas formation, are characteristic feature of hyper acidity . When there develops hyper acidity, patient try to eat something to relieve acid in stomach . This is the main reason of excessive hunger. Try raising the head of your bed about 4 inches with blocks. Avoid drinking or eating for 2 hours before you lie down. To help control stomach acid one should not drink drinks with caffeine in them or eat chocolate or greasy or spicy food. Also take some antacid
but if symptoms are severe then you may need drugs like proton pump
inhibitors as in in your case.
2 Tension is the 2nd most important reason of excessive appetite .Excessive eating also develops hyper acidity .
may be the next reason , diagnosis can be confirmed by H B A 1 C and blood sugar examination.
In my opinion consult a doctor and deal accordingly .
Good luck. Dr. HET
