Hi welcome to HCMForum. As you are thinking the surgery nor the vagus nerve
is causing the problem.
most probably botulinum is the cause of her problem. Any how gastroenterologist is the reply for both.
I suggest you to see the doctor for diagnosis and treatment. Besides i advise you some diet recome-
-ndations as take more of curd and bland foods. avoid spices chillies oily foods and junk foods. I hope
you are satisfied with my reply. thank you.
