Before you go getting your heart butchered, listen to my story. Dysautonomia began for me about your age--at 19. It started in the summer of 1996, during my first vacation from college. It started subtely; I'd drink too much espresso, stay out in the sun too long or go without eating, and my chest would start to pound. I didn't think much of it. Then I started peeing a lot--twice an hour sometimes; I was scared to death that it was diabetes, which runs in my family, but it wasn't. My doctor told me to cut down on caffeine and salt; that summer, I eliminated salt from my diet. That was my first big mistake. Over the next couple months, I began to notice that I'd get palpiatations after eating, esp. at breakfast--and my breakfasts were typical American: loaded with fried foods and carbs. Before long, I found myself having to lay down and sleep after every big meal. Dizziness on standing first appeared about this time as well. I endured this for a couple of years; my heart would race after eating, and I'd sleep; but the palpitations would usually be gone when I woke up. In 1998, I started taking Adderall. For two years I lived on it, espresso and candy bars--and all that made the symptoms worse when they wore off. I moved back home after graduating from college, and in January 2001, the panic started; panic attacks would hit me out of nowhere. The next three years were ****--I could barely do anything; my heart raced constantly, I was exhausted no matter how much I slept, and my brain was in a fog. It wasn't until late last year that I made a personal effort to end all this; I stopped listening to doctors and started eating better. I ate more salt and drank more water (lots of it); I cut out wheat, gluten and all refined sugars, as well as cheese and all dairy products; and I started taking an army of vitamins and supplements. The effect has been enormous. I rarely get dizzy on standing now, and haven't had a panic attack in quite some time. I don't get anxious. The only symptoms that really remain are the fatigue and the fog, and I plan on dealing with those soon by trying Adderall again. Now that the panic is under control, I may be able to resume it. (I still pee a lot, but that's such a minor symptom that I can deal with it and live my life). I strongly suspect that my dysautonomia was made worse by lack of salt, lack of water, and by wheat and sugar; when those were eliminated, the worst of the illness abated. I had no idea I was intolerant to wheat and sugar until I stopped eating them; the symptoms of the intolerance blended with and made worse the autonomic symptoms; I couldn't discern one from the other. Dysautonomia doesn't necessarily hit you all at once--my symptoms progressed over a number of years; your racing heart may just be the first sign of it. Before you go having surgery, which will chain you to a pacemaker for the rest of your life, try some dietary and other changes and see if they help. Give them a month or two.
