I just had my surgery last Wednesday it's been a week , I never needed any pain meds but in the hospital. I have lost 26 lbs and that seems too much. I have followed the diet to the letter, I have no hunger, no gas, no heartburn and am wondering why. I know to never look a gifthorse in the mouth but this seems too much and too fast. I dropped 2 lbs since yesterday and it is starting to worry me. I am 50 yrs old and was in good health at time of surgery. I hear a lot about weight lost after a month or more but no one told me I would lose this fast. What was odd was when I came home the next day after surgery my scale which I used the day of surgery said I weighed two lbs more. My Surgeon said that was from IV fluids. I can say I did have one problem if you can call it that...I was constipated for 5 days after surgery but they said that was normal. My sister is an RN and has taken all my vital signs and they are as they were before surgery with slight drop in BP, nothing big. I was a bodybuilder before I got fat if that means anything...even when I was fat I was still lifting and working out every day, you just could not see the muscles. I am afraid if I lose weight at this rate I will lose muscle. I'm drinking about 100 grams protein a day, 3 shakes of 30 grams and some Kefir yogurt with another 10 grams. I am drinking about 70 ounces of water..Propel. That's it. Should I be worried?
