Should I postpone my surgery of panniculectomy and abdominoplasty?

Should I postpone or continue? I've gained weight 15#...due to some RA and iron deficiency anemia issues... My RA is now under control and the pain and my anemia. I was told I'd still have a good result...it's not like I'm going to try to lose 50 pounds after sutgery. I just want to drop that extra 15 pounds. Should I postpone? I have lost 170# after gastric bypass 5 years ago.
