What is bariatric surgery?

Bariatric surgery is a weight-loss procedure that changes the size of your stomach to assist with weight loss, treats complications from obesity—such as joint pain, headaches, and reflux—and reduces the risk of heart attacks and strokes.

If you have a body mass index (BMI) of 30 or higher and are between the ages of 18-70, bariatric surgery could be the right treatment for you.

Obesity affects around 40% of all Americans, increasing the risk of developing heart disease, diabetes, and other chronic conditions.

Bariatric surgery options

ARC specializes in the following bariatric surgery procedures:

Vertical sleeve gastrectomy

This weight-loss surgery reduces the size of your stomach and limits the amount of food you can eat in one sitting. The route of digestion is preserved as part of the stomach is removed and the remaining is formed into a vertical sleeve. As a result, you will feel full sooner and longer.

Roux-en-y gastric bypass

Gastric bypass surgery alters the way your stomach and small intestine process food. The surgeon creates a small pouch in the stomach and attaches it directly to a portion of the small intestine. The small pouch allows food to bypass a part of the small intestine and reduces the amount of fat and calories you absorb from the foods you eat.

Endoscopic sleeve gastroplasty (ESG)

ESG is an incisionless, endoscopic approach to weight-loss surgery. During the ESG procedure, a flexible endoscope is inserted through your mouth into your stomach. While inside your stomach, the endoscope uses special suturing devices to create a series of permanent sutures. This reduces the size of your stomach, making it a smaller banana-shaped pouch. The smaller stomach size helps you control your appetite and limits the amount of food you can consume.

Bariatric revision surgery

Revision surgery is a personalized approach that contemplates the correction or improvement of previous bariatric surgeries depending on the type of bariatric surgery that was previously performed.

We will start with an EGD (upper endoscopy) of the esophagus and stomach to evaluate the general shape of the anatomy. Once we have that information, we can see what options are right for you.

Gastric band removal is a common revision in our practice.

  • Initial bariatric surgery consultation

    After attending the seminar, we will book you an appointment with bariatric surgeon, Marco Vinicio Medina-Zea, MD, FACS, FASMBS, to discuss your personalized care plan moving forward in the bariatric program. New patient appointments are focused on the individual patient and their health needs and concerns. You will also meet with the bariatric coordinator to discuss insurance-specific requirements for surgery and ask any questions that may have come up between the seminar and your appointment.

    Before this appointment, you will get a call from the financial counselor to discuss your insurance coverage. Bariatric surgery costs may be covered through some insurance plans.
