Any One With Apoe 3/4 Genetics On Here? Or Had A Triple Bipass?

I am 54 years old and have had a triple bipass already and APOe3/4 genetics with the LPa cholesterol, metabolic disorder. I have bmi of about 39.3. I dont have diabetes but all my siblings do. I wonder if a sleeve would help limit blockage. When I do the fat free diet I lose weight but only with walking 5 miles a day. My hair falls out, I get serious dry eye. But my cholesterol improves. I am pretty active and eat healthy for the most part. I have been on a wheat free diet for weeks now. I lost a few lbs. A normal person would have lost more. I wonder if it's safe for me because I keep blocking. Now my front wall of heart is blocked. Lap bands DO NOT work for our family. It's sad and I hate to have the sleeve if it won't help. Doctors here don't know either. Maybe someone knows of someone with this problem and could help. PLEASEEEEE? Also I have most of my weight on my abdomen and back. The worst place.

My doctors know the band won't work and are not sure of the sleeve because I dont metabolize fats well. And have the problem with the little cholesterol.
