Precautions for Anemic Patient Undergoing Multiple Cosmetic Surgeries?

Liposuction, irregardless of technique cause blood loss. In my personal experience with many buttock agumentation procedures, most patient's Hemoglobulin levels drops by 3-4 points after significant liposuction and brazilian buttock augmentation. therefore, I recommed that you start taking iron pills or even to consider iron transfusion, which does not carry the risk of blood transfusion.

Hi there-
The most important issue here is not really what you might be able to do to elevate your blood count, but rather finding out why it is low in the first place.
There are many possible causes for anemia, and some may require specific treatments.
Depending on what is causing your anemia and the treatment your doctor recommends, there may be things you can do to improve your blood count before surgery, or it may be that your doctor thinks you should wait to have your surgery until the condition causing the anemia improves.
Either way, you need to see your doctor. 

Anemia can affect your healing,  prolong your recovery time, and raise the chances of you needinga  blood transfusion after surgery.
As already mentioned,  you may need the help of your iternist or even a hematologist to diagnose and treat your anemia.
Many of my patients have had weight loss surgery, and are contemplating very big procedures.  Many also run a chronic anemia no matter what is done to treat it. 
Anemia is not about how low the number is (i.e. your Hb of 10.5)  but how your body has adjusted to it. 
So, cardio conditioning and aerobics can go a long way in helping your body acclimate to the anemia and thus lower your chances of needing a transfusion.

Anemia can be caused by many conditions. It is important that you discuss your condition with your plastic surgeon and have a full evaluation by your hematologist. You may want to separate your procedures to different times and not push to have all the procedures at the same time.

The treatment of your anemia depends on the diagnosis. If you have iron deficiency anemia or anemia due to blood loss, iron supplements will be the best choice. Pernicious anemia is treated with pernicious anemia. Anemia associated with renal disease may benefit from erythropoietin. You should discuss this with your primary care physician.
Given the extent of your surgical procedures, I would strongly consider staging your options if you were not capable of significantly elevating your blood count.
