Columbia Liposuction doctors

You should discuss this with your plastic surgeon. If your abdomen could stand improvement with liposuction, now would be a good time to do it - to make you look and feel better. You should not pursue liposuction of the abdomen to protect against future weight gain there. There is no data to support that areas that do not undergo liposuction will become heavier if other problem areas are suctioned.

There is no such thing as "Non Invasive Liposuction"!  .....No matter what some of the liposuction companies try to tell patients.  All forms of liposuction involves making an incision, usually injecting fluid (Tumescent fluid) then inserting either a liposuction cannula (standard or ultrasonic) or a laser cannula followed by a liposuction cannula.  Once an incision is made and an instrument is inserted under your skin, that is called invasive.  Laser liposuction is more invasive than standard liposuction.  Not only is liposuction still performed, but in addition to that, a laser beam is first inserted and used to burn your fat and heat up your tissues.  That's even more invasive and increases your risk of complications! 
CoolSculpting is a non invasive procedure to kill some of your fat cells from the outside, with no incisions, no anesthesia, and no downtime.  But this is best for people who only have small pockets of fat.

Just because someone tells you something or just because you have read it somewhere, doesn't make it true.  The fact is, the number of fat cells you are born with, (or at least the number you have after puberty) is the same number you will die with.  When you gain weight, they will get larger.  When you lose weight, they will shrink.  They don't multiply and they don't go away.  Those are the facts for normal/healthy, non obese people!  If you gain a lot of weight and become obese, the scientific data shows that you can make new fat cells.   Fat cells can only hold a limited amount of fat.  So, if you keep eating more and more and become obese, your stem cells will begin making new fat cells.  This is science and fact!  Fat cells do not redistribute! Fat cells do not move around your body.  How much fat is stored in your cells can change (or redistribute)  throughout your life.  You may gain more in certain areas when you are young and gain more in other areas when you are older.  But, you do not make new cells unless there is some need for them. 
Most patients do not gain weight after a tummy tuck.  Most actually lose additional weight because they look better, feel better and their self confidence gets a boost.  AS far as optimum BMI.... Anywhere below 30 is considered optimum and safe as long as you are in good health.
Liposuction is used to make you slimmer and improve your shape.  TummyTucks are done to tighten skin and muscle.  They are extremely different.  Liposuction of your flanks does not make Tummy Tuck results any better.  It makes your figure better if you need it!
