Thank you for your question. Your body is no different from celebrities, what you may keep in mind is that they live of their appearance, so usually they are in great physical shape by exercising with a trainer and eating healthy through special balanced diets given by their doctors or trainers, so the secret is actually minting your physical shape throughout pregnancy. The quick rise in popularity in aesthetic plastic surgery worldwide has led to a movement of aesthetic surgeons who are not plastic surgeons, sometimes they are gynecologists or general surgeons, and are getting aesthetic surgery degrees by taking three day courses. This has led to some bizarre practices like the ones you talked about. During pregnancy, in the final trimester, your body develops what is called dilution anemia, as it prepares to bleed, so it is totally absurd to submit your body to an additional unnecessary procedure during the critical moment of a C section. On top of that, your internal organs must heal and retract to their original position before you even consider a tummy tuck, and that period is usually 6 to 12 months. Tummy tuck procedures and lipectomy procedures(when you cut excess skin without muscle repair) performed during C section should be legally punishable by authorities, but sadly it doesn't happen.
