Weird Question - I may be losing too much weight pre surgery

I am began seeing my surgeon in May and my BMI was 40.8. I was told that my insurance will cover in cases where you have a BMI over 40 or over 35 with an obese related condition which I have-hypertension and high cholesterol.Three weeks ago I saw the dietician *****commended losing weight pre-surgery. I have been on South Beach diet since. I have lost over 20 LBS. so far and and my BMI is currently 38.5. My Surgery is tentatively scheduled for Dec. 1. I don't want to stop my diet however is I lose more than 25 more lbs. my BMI will drop below 35. I believe there is a distinct possibility this will happen as I have lost up to 80 lbs twice in the last 10 years (only to eventually gain back nearly all. Losing weight for me is not nearly an issue as keeping it off, so I find myself in a bit of a quandary. Any suggestions or advise would be appreciated.

Losing too much weight?  We've got a trouble-maker in the crowd :)  No, seriously, you've raised a valid question even though I am guessing your insurance uses the BMI number you were approved at.  However.....more importantly, do you feel like reconsidering?  You've got ample time to do so.  I found great comfort in knowing I could back out of surgery up until the very last minute of the very last day.  I didn't, though, knowing my 52-year old joints, blood sugars, heart, and very existence was in trouble.  I didn't have one more, "I can do it this time" left in me.  Maybe you do.

I truly know that I can lose lots of weight "I can do it this time"   just as I truly know that maybe not in a year but definitely within 3, I will gain it all back possibly with interest. I need this surgery to remain committed. I've been on a obesity roller coast my whole life and need to get my life and health back.

And yes I was approved by my insurance based on the BMI #s stated in my original post.

...with interest...lol   Yes, losing five was the quickest way to gain ten.  I sensed hints of surgery-doubt in your past posts until this one. It's best to make a phone call assuring WLS is "a go" so you can forge ahead with even more pre-WLS accomplishments.  I was a professional loser before WLS, also, knowing all too well the frustration of regain. So much so, the obesity roller coaster you speak of still plaques my thoughts sometimes thinking  "when is this dream going to be over."  Thankfully, those thoughts are diminishing with time.  However, I will always stay fresh with gratitude to have my life and health back.  Wishing the same for you.

I'd ring up your surgeons office and see what they say. For my province, you qualify with a BMI greater than 40, or greater than 35 with at least one co-morbidity. All patients will have to go through some sort of pre-op diet.  For myself, my surgeon has his patients do a 30 day liver shrink diet of Glucerna and water before surgery. So long as you still qualify for surgery, the surgical team prefers you weigh as little as possible as your risk of surgical complications go down with your weight.

It can happen that an insurance will deny surgery because you "proved" you could do it on your own.  My surgeon's office quietly and not officially told me not to get under my required BMI before surgery was approved.  I followed the six month diet, but stayed at 38.7.  But once I was approved, I did lose quickly and was at 36 on surgery day.  The weight loss before surgery only makes things easier afterwards. 

The difference between surgery and countless other diets is that after surgery I was able to keep the weight off and keep losing down to my goal and lower. 

I agree with the other posts.   Find out from the Surgeons office what you should do to stay qualified.... believe me, as a life long yo-yo dieter who had lost over 100 lbs at a time because "this time I'm motivated and can do it"  only to see it all come back on and more because of some horrible thing which happened in my life which could only be fixed with my food addiction... there is nothing like the RNY surgery.  It has completely changed my life and the way I look at food and deal with food.   Before surgery I could eat an entire pizza, a cake and half gallon of ice cream and still be hungry.  I was always feeding that hunger.... now.... completely different.  I rarely get hungry and all it takes is a few bites of protein and I'm good to go.  I've lost over 90 lbs in the 3 months since surgery and feel amazing.  I work out at the gym and walk, walk, walk.   New Life.   Now, when some horrible thing happens,  even though my thoughts go to food,  I KNOW I CAN"T becuase of my new stomach and for some reason, that takes the hunger away and I go for a walk or to the gym or do something else instead of eating.  Also, the amount of money I've saved from not spending every penny on junk food is amazing too.  I'm shocked that my local McDonald's is still in business without me eating there 4 times a day!   :)     Good Luck!   Make it work!  It is worth it!
