Explore personalized surgical weight-loss procedures designed to support lasting health and a better quality of life.

Bariatric surgery can be an effective treatment for individuals who have struggled to achieve lasting weight loss through diet, exercise, or medically managed programs alone. At Advanced Bariatrics of Northern Illinois, our experienced surgeons provide minimally invasive procedures tailored to each patient’s health, goals, and individual needs.
Gastric sleeve surgery, also called sleeve gastrectomy, reduces the stomach to a smaller, sleeve-shaped structure. This limits the amount of food that can be consumed and creates hormonal changes that can help reduce hunger and support significant weight loss.


Gastric bypass, also known as Roux-en-Y gastric bypass, creates a smaller stomach pouch and redirects part of the digestive system. This procedure helps patients feel satisfied with smaller portions while changing how the body absorbs calories and responds to food.
SADI-S combines a sleeve gastrectomy with an intestinal bypass. The procedure is designed to reduce hunger, limit food intake, and decrease calorie absorption. It may be considered for patients who require a more powerful surgical weight-loss option.


Revisional bariatric surgery may be recommended when a previous weight-loss procedure has not produced the desired results or has caused complications. Our surgeons carefully evaluate each patient’s original procedure, current health, symptoms, and goals to determine whether a revision or conversion may provide a safer and more effective path forward.
There is no single procedure that is right for every patient. Your surgeon will consider your weight-loss goals, medical history, existing health conditions, previous treatments, and lifestyle before recommending an option. Our team will explain the potential benefits, risks, and long-term requirements of each procedure so you can make an informed decision.


Bariatric surgery may be considered for adults with a body mass index of 35 or greater, or a BMI of 30 or greater when certain weight-related health conditions are present. Insurance requirements may vary, and every patient must complete a comprehensive medical evaluation before surgery.
Whenever appropriate, our surgeons use minimally invasive laparoscopic or robotic techniques. These approaches typically involve smaller incisions and may support a more comfortable recovery.
The most appropriate procedure depends on your medical history, current health, weight-loss goals, and ability to follow the recommended lifestyle changes. Your surgeon will review these factors with you during your consultation.
Yes. Long-term success requires changes to eating habits, physical activity, vitamins, medical follow-up, and other aspects of daily life. Our multidisciplinary team provides continued education and support throughout the process.
