taking hints by the history you have provided , i believe you may be suffering from gastroesophageal reflux disease
.i would need important relevant data regarding your height , dietary habits , alcohol consumption ,snoring
during sleep and working hours for further evaluation. however in the absence of this piece of information , i can advise you to reduce your weight if you are obese, quit smoking if you smoke, avoid fatty and spicy food stuff , elevate the head end of your bed by about 30 degrees before sleeping, gargle regularly with warm saline water thrice a day for 5 min each time and of course continue your omeprazole
capsule. as for the problem of belching
,i believe you have become too conscious of your problem and may have become habitual of belching by yourself.
just try to get rid of this habit by using a sugar free chewing gum when at the desk. if too much flatulence
is present with foul odor , it may be worthwhile to undergo a routine stool examination with culture sensitivity test.
good luck and god bless.
