Hi.
Thanks for your query.
Noted the history and understood your concerns.
Since you are a diagnosed case of GERD with acidity problems that inability to swallow;
Ranitidine causing breathlessness,
Omeprazole causing more throat swelling which is very rare and should be thought about as you already have throat pain.
Yes,
Gaviscon will help to an extent but you also need medication to suppress the acid production:
I would advise you the following in such a situation:
Try Famoditine as acid suppressor.
Gaviscon to be taken when on empty stomach.
Diet as you already know avoiding all the foods and beverages that increase the problems.
Control of stress and anxiety are of utmost importance as these add-on the existing problems and a good control helps good control over GERD.
Consult a Gastroenterologist for proper clinical review and evaluation.
Upper GI
Endoscopy.
Esophageal Manometry studies.
Barium swallow and mean studies to know the dynamics of the problems.
Tests of blood for sugar, thyroid and liver functions.
Additional medications as advised and you will be improved a lot.
