hello and welcome to HCM,
Since you have been diagnosed with GORD and a treatment has been initiated but not properly continued by you I would advice you to properly continue the treatment. If lanso does not suit you and if ranitidine
does not have much effect then ask your doctor to prescribe you any other anti-reflux medication
and continue the same for a minimum period of at least two months for proper symptom control.
Follow the anti reflux measures such as avoiding spicy food, oily food and having proper meal at proper interval.
Also avoid tight dresses and do not immediately lie down after a meal.
Regarding your abdomen problem it is imperative than you consult a general surgeon
to get a proper diagnosis and treatment.
Try also losing weight if you are over weight
take care and get well soon
Dr Sriram Nathan
