In the event of weight gain can I have my abdomen treated with Vaser again if I have used the same treatment in the same area before?
Yes it is possible to perform percutaneous Lipo in the same area. One Should space out six month between procedure on same area.
Possible, yes. Advisable, no. In the event of weight gain, you should look into diet and exercise to enable weight loss. Liposuction is not appropriate for weight loss.
