About Advanced Bariatrics
Expert Bariatric Care Centered Around You
Advanced Bariatrics of Northern Illinois provides personalized surgical and medical weight loss care for patients throughout Chicago’s northwest suburbs. Our experienced team combines advanced treatment options, compassionate support, and long-term guidance to help each patient build a healthier future.
A Supportive, Judgment-Free Approach to Weight Loss
Obesity is a complex, chronic medical condition. It is not a personal failure, and patients should never feel judged when seeking help.
Advanced Bariatrics was created to give individuals struggling with obesity a supportive place to explore their options and receive care tailored to their needs. We take the time to understand your health history, challenges, and goals before recommending a treatment plan.
Whether your path includes bariatric surgery, medical weight loss, or a combination of services, you will have a knowledgeable team supporting you throughout your journey.
Who We Are
Personalized Treatment
Your health history, lifestyle, concerns, and goals are unique. Your treatment plan should be too.
Compassionate Support
We provide respectful, judgment-free care in an environment where patients can feel heard and understood.
Long-Term Guidance
Our relationship does not end after surgery. We remain a resource as you develop new habits and work toward lasting health.
Experience You Can Trust
Advanced Bariatrics is led by fellowship-trained bariatric surgeons Dr. John Cheregi, Dr. Hsin-Yi Chang, and Dr. Daniel Hoeltgen. Together, they bring more than 20 years of combined experience caring for patients with obesity and performing advanced weight loss procedures.
Our surgeons use minimally invasive techniques, including robotic-assisted surgery when appropriate, to provide individualized care. For particularly complex cases, our surgeons can collaborate closely to determine the safest and most effective approach.
Surgical options include:
- Gastric Sleeve Surgery
- Gastric Bypass Surgery
- SADI-S Surgery
- Revisional Bariatric Surgery
More Than a Surgical Practice
Successful weight loss requires more than a procedure. Our multidisciplinary team includes bariatric surgeons, a nurse practitioner, registered dietitians, program coordinators, and additional support professionals who help patients prepare for treatment and maintain progress afterward.
From your first consultation through nutrition education, surgery, follow-up visits, and long-term support, our team is here to answer questions, celebrate progress, and help you navigate challenges.
