I had an abdominoplasty along with a breast augmentation & lift (385cc). I am currently 10 weeks post op. I have started back to the gym as of 2 weeks ago. I run for 20 min and then free weights. I eat mini meals every 2-3 hours, mostly veggies, fruit, and lean meat. In the last 2 weeks I've gained 8 pounds and I've had to go up a size in my jeans. Why is this happening?
