I Have Experienced Vasovagal Syncope Before Throwing Up Since Childhood.

I have experienced vasovagal syncope before throwing up since childhood. Last night, I was extremely ill with an apparent stomach virus. My husband witnessed repeated incidences of syncope, from which he was able to arouse me. He was frightened. It happened as many as ten times in a 3-4 hour period. I also had concurrent diarrhea urination while throwing up. I have multiple gland failure, including adrenal dysfunction with low vasopressin. Is this related to that?
