Elizabeth Alexandra Zubowicz, MD, FACS, FASMBS is a board-certified general surgeon. She specializes in bariatric surgery and hernia surgery. She performs both open as well as minimally invasive surgery, with a focus on robotic surgery and its advancement in the realm of general surgery. She has performed over 1000 bariatric procedures and has a passion for helping patients get healthier.
One of the biggest concerns post bariatric surgery is “loose skin.” After so much hard work and effort to lose weight and get healthier, patients still have this loose skin that can significantly impact their quality of life and self-image. Skin removal surgery is rarely covered by insurance and can be an extremely long and painful recovery.
In addition, being a mother of 2, she personally felt the body image challenges of having permanent loose/sagging abdominal skin no matter how many crunches after having babies. After extensive research, Dr. Zubowicz was impressed by the significant results from minimally laser techniques for loose/wrinkled skin and decided to incorporate it into her practice.
This market-leading body-contouring technology can be used on many areas of the body and can help improve skin laxity after weight loss, pregnancy or aging. It is also great for removing those last stubborn areas of fat that just can’t be lost no matter how much weight one loses.
She is extremely excited to now offer these skin tightening and rejuvenating techniques as well as other minimally invasive approaches to graceful aging and improved overall body wellness at Thrive Medspa.
Dr. E. Alexandra Zubowicz is a board-certified general surgeon and a Fellow of the American Society for Metabolic and Bariatric Surgery as well as the American College of Surgeons. Dr. Zubowicz received her medical degree from University of Texas Health Science Center San Antonio. She completed her residency at the Georgetown-Medstar General Surgery Residency Program in Washington, DC. She has presented at numerous regional and national conferences and has been published in multiple peer-reviewed publications.
