Ketogenic Diet Before Weight Loss Surgery


Ariel Ortiz, MD

Dr. Ariel Ortiz, MD is a General Surgeon with a specialty in Bariatric Surgery and nearly two decades of experience in the field of weight loss surgery. He is Double Board Certified in General Surgery and Board Certified in Bariatric Surgery, holding two professional licenses: a General Medical License and a General Surgery License. Dr. Ortiz gained a reputation early on after deciding to pursue Bariatric Surgery as his specialty in 1997. In the late ‘90s, only a handful of surgeons were specialized in this field.

Dr. Ortiz worked as a consultant training the first surgeons aspiring to learn bariatric surgery, and traveled and lectured extensively in the United States and Canada. He played a key role in the development and clinical application of implantable medical devices for weight loss surgery, namely the Lap-Band System. World-famous for his work, Dr. Ortiz is considered a leading authority in the field of bariatric surgery, including the gastric sleeve, gastric bypass, and other bariatric surgery procedures. He has been named Director of the first Bariatric Surgery Online Television channel where he lectures and trains other surgeons in the technical nuances of complex bariatric surgery procedures.

Dr. Ortiz performed the first banding of a gastric bypass to rescue a failing procedure. He published this experience which led to it becoming the standard with which failed bypasses are treated around the world. His expertise in the bariatric field, as well as his ability to innovate and adapt, helped him design the world’s first weight loss surgery requiring no stapling, re-routing, or device implant and trademarked it as the Stomach Sparing Gastric Sleeve®.

Dr. Ortiz’s most recent collaboration resulted in the development and clinical use of the World’s First Swallowable Gastric Balloon for Non-Surgical Weight Loss and now benefits thousands of patients around the world each year. He actively teaches Bariatric Surgery at one of the designated sites for formal bariatric surgery training in Latin America. He is a surgical and academic consultant for Medtronics Medical®, Ethicon
Endosurgery, and Obalon Therapeutics®.”
