Can I have a tummy tuck, breast reduction and BBL if I have sickle cell disease?

Hi and welcome to our forum!
In order to determine your candidacy for elective cosmetic surgery, you require a hematology consultation as a sickle cell crisis must be avoided at all costs. 
If deemed stable and of low risk, you could be considered a candidate. The extent of surgery should be minimized, perhaps by breaking up the procedure into multiple procedures of smaller magnitude. 
Your hemoglobin is satisfactory. Your oxygenation must be maintained as well.

There are some very interesting treatments now for SCD.  I would visit with your Hematologist prior to any surgery to discuss strategies for management for treatment after surgery and to get clearance for the procedure.  I personally would not do BB, BBR and TT in one operation though; that is too much surgery for one day.  

As you likely know, sickle cell disease is associated with a greater potential for perioperative morbidity and mortality. Therefore, I would suggest that you exercise extreme caution as you make your decisions. Collaboration with your primary care physician and hematologist will be the first step. Then, once you've achieved "clearance" to proceed, select your plastic surgeon very carefully. Make sure that he/she is a well experienced board certified plastic surgeon who works with an experienced board-certified anesthesiologist in a fully accredited surgical facility. The operations you are considering are too much to be done one stage, given the circumstances. Again, proceed with caution;  make your decisions very carefully. Best wishes.
