Why does most women hemoglobin level drops after having lipo and bbl? What can I do to prevent it from happening?

Hemoglobin levels can drop from 1 to 3 points following 360 lipo and BBL. This is why we advocate that your starting hemoglobin be at least 13 on your preop labs prior to undergoing high definition liposuction. Please consider a virtual consultation with a high def provider to appreciate how you can avoid unnecessary blood loss by avoiding blood thinning foods, medicines, and supplements.

hemoglobin and hematocrit levels will drop from blood loss which happens during surgical procedures.
There can also be changes due to chemo dilution or Volume deficit’s.
Typically Liposuction with or without fat transfer procedures if done with good surgical technique have little blood loss.
Rarely more than donating a unit of blood.
A red blood cell has an average lifespan of 120 days and I replaced fairly frequently.
The body will be stimulated produce more red blood cells from blood loss and usually compensates quite quickly.Changes in hemoglobin or hematocrit levels from surgery is not gender dependent.
