Has anybody's doctor told them that because they have a bmi of 34 they didn't have to do pre op diet??

Just wondering

I just had surgery and my BMI was 29 and I did not do a diet prior to surgery either .

Like Benjamin said it's usually has to do with your liver. Also the preop diet prepares you for the first few weeks post op. Getting your used to doing liquids and such.

My nutritionist said everyone has to do the pre-op diet but the length of time you have to be on it is determined by your BMI. So if I can get my BMI lower i won't have to be on the preop diet as long , which in my case is alternating between 800 and 1200 calories a day.

My BMI was 40, and I had no pre op diet. Surgeons vary on what they prefer.

My doctor requires a 10% loss before surgery (except in low BMI cases). I was required to stay the same until insurance approval. Now she would like me to lose a little if I can to help with the liver shrinkage. She explained that a fatty liver is easily damaged during surgery because it's so much softer. The retractors can slice right thru a really fatty liver. During weight loss the liver shrinks and is harder to damage during surgery. No pre-op diet for me, just clear liquids the last day and nothing after midnight the night before and the day of.

Surgeons' policies on pre-op diets vary widely in length, composition and intent of the diet as well as whether or not one is needed at all. Diets for the sake of weight loss or post-op practice are of dubious merit while those for "liver shrinkage" do have some value for those docs who need that extra help. My doc doesn't do pre-op diets, other than the typical day-before surgery diet, no matter what the patient's BMI is. The best thing is to check with the surgeon or his office to see what his practice is.

I had a low bmi and didn't need a pre-op. However I used the week before surgery to wean myself off caffeine and sugar,. Lost 5 pounds that week LOL

I lost weight on the program the NUT gave me during my 3 month insurance directed visits. At my pre-surgery visit, the doctor said I wouldn't have to do the protein shake diet for a week before surgery. I do have to do the clear liquid the day before surgery.
