Weight loss surgery is about more than just losing weight. In our Arizona-based practice, bariatric surgery offers hope to those who are significantly overweight – hope for a healthier, longer, fuller life. Multiple studies have shown that most obesity related health issues can be resolved with bariatric surgery.
