Really swollen 10 weeks after Smart Lipo surgery. Is fat coming back? Haven't wore binder after 1st week, it cuts my breast skin

With or without applying a binder for the first few weeks post lipo, patients will experience a post-inflammatory reaction to the procedure. Inflammatory fluid collects in the subcutaneous space. Patients are often unhappy that they cannot "see" the results initially. Not to worry! You have already noted a significant improvement in your waistline. After the fluid under your skin subsides (several months) you will be able to appreciate your new shape. Perhaps ask your surgeon about seeking care from a lymphatic massage specialist. Hope this finds you well.

Hi and welcome to our forum!
Congratulations on your recent surgery. You are only 2 1/2 months post surgery. In our practice, we usually recommend the use of a compression garment for the first 6 weeks to control swelling, prevent bleeding or fluid accumulation. After that time, its usefulness is questionable. 
Resolution of swelling takes 6 months to one year. Be patient. 
Best wishes...

If you can,try not to worry so much.  I know that can be tough.  Remember it takes up to 6 months for all swelling to completely resolve.  As long as you follow the directions from your doctor for the post operative care and have a clean/healthy diet you will continue to lose inches and get to the goal you have set for yourself.  Keep up the good work!
