What causes a cold feeling in the stomach.... I am being treated for GERD and have been for 2 years, also constipation is a problem

I have not heard of a cold feeling in the stomach before but it is probably all part of your GERD. What are you doing to help with your condition? Have you had any medication for it?

I have had that cold feeling in the stomach and it can some time come into play when your core temperature is low and that can be from any number of things. I can remember that when my father had his chart operation, because the body had been cut open the core temperature was lowered and it took some time for him to get back to his normal body temperature. I am sure that our problem is not that but if you are still having trouble you can see what your doctor says.
