Is it normal to become swollen everytime I take my faja off at night time?

Swelling is common and expected after tummy tuck surgery.  As you progress through recovery and return to normal routines you will find that it may fluctuate with your activity level.  Swelling will last for several months yet.  I encourage you to discuss your concerns with your surgeon and follow all post operative instructions.

This is a great question. Swelling (edema) after any injury (surgery included) results when the lymphatics draining the area are overwhelmed and water backs up into the tissues. Areas of healing are metabolically very active and require increased blood supply and leak more fluid, thus the swelling until the system recovers. This can take months to completely resolve but most of this improves over the first 6-8 weeks. I tell my patients that salty food, alcohol and increased activity will make this swelling worse and each patient after about 3 weeks needs to discover what the tissue will tolerate and not get too swollen. Compression garments squeeze the tissue and may help this resolution but, when removed, the swelling returns until the body is fully recovered. This is all a natural occurrence of any surgery. Keep the faith, it sounds like you are doing great and this will improve in the coming weeks.
