Dr. Alvarez specializes in sleeve gastrectomy and revision bariatric surgery using this surgical method. Gastric sleeve surgery involves the removal of the left side of the stomach and creation of a small stomach pouch in the shape of a sleeve. Gastric sleeve surgery limits food intake as well as hunger sensations because it eliminates the part of the stomach known to produce a hunger-stimulating hormone called Ghrelin. Dr. Alvarez is also adept at performing sleeve gastrectomy on patients who have previously undergone an adjustable gastric band (Lap Band or Realize Band) procedure and are not comfortable with their band due to poor weight loss, high cost of maintenance, or postoperative complications such as band slippage or erosion of the gastric band.

Dr. Alvarez and his outstanding medical team perform vertical sleeve gastrectomy at Clinica de Especialistas Hospital, located just 1 mile from the Eagle Pass, Texas / Piedras Negras, Mexico border. The facility is widely recognized as one of the most advanced in the region and provides patients with 24-hour comprehensive medical care. For patients who are traveling to Mexico to undergo weight loss surgery, Dr. Alvarez and his medical team are happy to assist with travel arrangements and door-to-door transportation. Patients in the hospital are also provided with free Internet access, desktop computers and international phone calls.


The Centro Medico Piedras Negras is one of the most advanced hospital facilities in the region.
