Hi.
Thanks for your query.
Noted the history about your husband and understood your concerns.
Since the reports of
Colonoscopy, Endoscopy, CT scan X-ray of the chest are normal and
cholecystectomy has not solved his problems, the causes of belching, abdominal discomfort, feeling of choking, dry heaves and
weight loss can be due to the following reasons:
Stress and/or anxiety can be the most major reasons in case of normal reports.
I would advise him the following:
Get an evaluation by a
Psychiatrist too to find out any problems that is causing such symptoms.
Transposition of
great vessels can not be the reason for such symptoms and better be taken care by the Cardiologist and also take an opinion of a Cardio-thoracic Surgeon.
Change of place, job, relieving him all the factors that cause or enhance the symptoms including the foods and beverages can help him further.
Proper medications as per the cause found as well as symptomatic treatment may help your husband.
