Hello @janicejuly51 and welcome to Mayo Clinic Connect. I think it is very aware of you to try to make connections. I was able to find another discussion that mentions possible diagnosis of glycogen storage disease that I thought may be helpful: https://connect.mayoclinic.org/discussion/attacks-of-repeated-belching-pain-sweating-and-dizziness/

Have you ever been given reason to think they may all be connected by a doctor or are you just adding things up and wondering if you may be onto something?
