Hi.
Thanks for your query.
Noted the history and understood your concerns.
You are taking Happi IT tablet that is
Rabeprazole the PPI and
Itopride which is a motility regulator and is actually given for
hyperacidity related problems along with
motility disorder and helps in reducing the
bloating.
Since you are taking this for 2 months and getting increased size in stomach in spite of maintained weight mean there may be a problem as follows:
Deposition of fat in abdominal wall.
Gaseous distension of the intestines.
Ascites that is accumulation of fluid in the abdominal cavity.
This may not be due to the medication that you are taking.
You may still do the following:
Stop Happi IT and take plain Happi that is Rabeprazole and see for the results.
Investigation of the abdomen by Contrast enhanced CT scan, Standing X-ray of the abdomen.
Tests of blood for sugar, thyroid , liver and kidney functions.
Tests of stool and urine.
Clinical evaluation by a Gastroenterologist.
All these will lead to a proper diagnosis and gives a plan for proper management.
