Hi. Thanks for your query. Noted the history about your husband about suffering from duodenal polyp which is not cancerous as per the biopsy report, smokes, had heart attack, there is also breathing trouble. The Duodenal polyp could have been removed endoscopically as it is benign. I would advise him the following: Stop smoking altogether as he had heart attack. To continue the cardiac medicines religiously. Consult another Endoscopist who is known to tackle the duodenal polyp by Endoscope. Re-get the histo-pathology reports and decide the further course of management if anything specific is found. Yes, obviously the weight should also be reduced by proper diet control and exercises.
