Follow the guidelines as directed.
The obesity itself can be a part of the reasons of your ''gastric'' problems.
First of all get the constipation
treated by mild laxatives like cremaffin
plus at bed-time- the doses to be taken as per suits you; start with 2 teaspoonfuls and you can reduce or increase the dose as per your suitability.
You need to undergo the upper GI endoscopy
of abdomen, may be barium study of the esophagus
and stomach to come to a diagnosis.
Remember Ayurvedic and other supplements you are taking can enhance the problems; you can stop them for sometime to see if it helps.
Till you go through the investigations I would advise you to take tablet Motilium
-M 10 mg 1-1 at 6 am - 2 pm and 10 pm; meaning at 8 hourly interval along with plain Sompraz once daily.
Go for bland diet, small frequent meals, exercises in moderate way, follow the chart your dietitian advises you, do no lye down after food - have a walk; No smoking
or tobacco in any form/ drinking alcohol. A life-style which allows a sound sleep of 6 to 8 hours solves many problems.
Always take help of your family as their persistence helps more than a Doctor's advise.
Consultation with a Gastoenterologist is most advisable, as you may need prescriptions/ advise and endoscopy.
