I am writing to you from the hospital. I was working when I had an vasovagal episode. I did not pass out, but I was diaphoretic, felt prickling in my forearms (almost like I could feel my blood moving inside). When I sat down it went away. After the third episode, I went to the ER. There I was worked up in the same manner (cardiac / brain). All negative. My 24 hour halter monitor also negative.
I believe that my lap band is pressing up against my diaphragm due to a small HH diagnosed on a CT for an unrelated issue. When my fundus is "full" which can be just taking a sip of water and my medications...it pulls up the stomach more and this increases the pressure of my band on the diaphragm. I believe this is causing a vasovagal episode when you add PHYSICAL ACTIVITY which involves the abdominal muscles (I work in healthcare and my job involves the usual pushing and lifting etc.).
Unfortunately, the ER doctor, the hospitalist who admitted me and the cardiologist all POO-POO'D my theory. There was a nurse practitioner, a PA and the neurologist who agreed with me and suggested I follow up with GI pathway as I continued to pursue the line of diagnostic tests already ordered for neuro.
This has been a very expensive experience for me and frustrating, since I live alone and fainting periodically is not ideal (especially if I am driving alone - which I do 24/7/365!!! Just thought I would add my two cents for what it was worth.
