Procedures Performed

Dr. Rene Armenta performs a variety of bariatric procedures, including the Gastric Balloon process and the Gastric Sleeve surgery.

Gastric Balloon Process

Known as the intragastric balloon, the Gastric Balloon offers a non-surgical avenue for losing weight. The technique introduces a balloon endoscopically into the stomach, then fills it with a saline mix to take up some stomach space. Once puffed up, the balloon stays in the stomach, giving a feeling of fullness once you start eating your meal. Generally, an outpatient process involves a light sedative, and most patients return home the same day. The balloon stays in your stomach for up to six months, during which eating habits are reshaped under expert care. When it's time for extraction, the removal procedure is the same as insertion.

The Gastric Sleeve Surgery

The Gastric Sleeve operation, or Sleeve Gastrectomy, removes about 85% of the stomach. What remains is a stomach with a 70-90 ml capacity, drastically decreasing the food portions you can handle, thereby changing how you eat. Once the stomach section is removed, the production of the ghrelin hormone, which is in charge of producing your appetite, drops 95% - toning down your hunger and food-related stress. The operation, done under general anesthesia and using a minimally invasive strategy, promises a speedy recovery.
