Digestion Q&A by Dr. Marks

I have been taking omeprazole (Prilosec) on and off for 3 years. Of late, there seems to be less relief for my unusual dyspepsia. At times I can feel the acid rushing out as it gives a warm sensation inside my stomach. When I get excessive acid, I experience heart palpitations and become weak. I understand there is a procedure whereby a nerve controlling acid secretion can be deaden to reduce acid secretion. Where can I find more information.

The nerve that is important in promoting acid secretion by the stomach is the vagus nerve. Operations for treating ulcers in the stomach and duodenum include cutting the vagus nerve (vagotomy) to reduce the secretion of acid by the stomach. (Vagotomy is not used for treating acid reflux.) These operations and vagotomy are performed infrequently now because of the effectiveness of medications like omeprazole (Prilosec) at reducing acid and thereby healing or preventing ulcers.

Thank you for your question.
