I had grastric by-pass done about four months ago. I started out at 306 at the time of my surgery and am down to 245lbs (this is without exercise), due to a fractured fussion at the L3 and 4 level. I went into this with a very possitive outlook, I was a type II diabetic, high blood pressure, atrial fibrulation, asthma, and many other medical problems, I knew to take the surgery seriously, and that I would have to follow instruction to the tee, before and after or not doing so can cause problems, so I did. I followed everthing exactly as I was instructed, and I have not had any problems. Yes! I had to add protien to my meals for a little bit, but soon I was able to eat enough with my meals alone, the additional protien was not require. I only have to take two childrens vitamins, two tums (for calcium) all chewable and a liquid iron; no big deal, these are instructed and explained to you before you make the choice to have the surgery, no suprises. I have had such good results, I was on so much medication (12 different meds in the AM and 11 in the PM), I now only take 4 in the mornings and 3 at night. No more diabetes, blood pressure is great, as well as my asthma. My health is soooo much better it was the right thing for me to do. Everbodys reason and problems are different, but the one thing I can tell you all is be true to yourself if you choose to have the surgery make sure you listen, and follow all instructions, another words do as your told, there are reasons for what they tell you to do even if you do not understand what reason is. I have done so well, and feel so much better than I have in years. I have had no problems and I expect to live alot longer than what I would of if I had not had the surgery. My advice, pray-about the reason for the surgery, ask questions of your self and especialy of your doctor make sure you understand everything before making a decision. Be knowlegable whats required before and after your surgery. ASK, ASK, ASK. UNTIL YOU UNDERSTAND!
