Hello and welcome to HCM,
The bloating sensation is possibly due to gastrointestinal reflux disease (GERD).
The drug that you are taking -
omeprazole 20 mg is to treat GERD.
It prevents the reflux and thus prevents water brash,
acid reflux, burning sensation, bloating and other symptoms of GERD.
However, since you are still suffering from bloating despite taking medication for reflux, I am of the opinion that the symptoms are not due to GERD.
Bloating can also occur in disorders of liver or
gall bladder.
In addition, nausea after having food could also be due to liver disorder.
I suggest you to get liver function tests done along with
ultrasound abdomen.
Gall stones often cause bloating, nausea, vomiting etc after having food.
Ultrasound abdomen will help to detect gall stones.
Management can be planned after the investigations.
You can even consult a physician if you are unable to get appointment of a gastroenterologist.
Thanks and take care
Dr Shailja Puri
