It has nothing to do with personality disorders and everything to do with what each 10 pounds lost brings to your life. With me, the first 10 pounds was before surgery. It was a great loss, but not much changing. Now, post surgery, every 10 pounds I have lost has brought new changes, new challenges to overcome, a new person every 10 pounds basically. The first 10 was a denial within myself that despite the weight loss that anything was really changing with my body. The second 10 was a realization that I can't wear most of my wardrobe because it's all too big. Along with that realization came the realization that I'm wearing clothes I haven't worn in 20 years. Is 90% of the changes psychological? Yes! Did they constitute mental disorders? Do a lot of us have mental issues? Yes! But the changes that come with the rapid weight loss are NOT serious personality disorders!!! I can't believe one would even correlate a personality disorder with the changes that we all undergo as a result of our respective surgeries!
