Why is cosmetic surgery called plastic?

I had bariatric surgery done by Dr. Amman and I am doing well now. However, I have a lot of loose, hanging skin on my stomach, which is causing me serious back pain and leg fatigue. I would like to undergo a tummy tuck (abdominoplasty) to remove the excess skin and improve my comfort and mobility. Please guide me on
