Comprehensive Weight Management, From Medications to Bariatric Surgery

Obesity is a complex, chronic disease — not a failure of willpower. At the USC Weight Management Center, we treat the biological, medical, nutritional and behavioral factors that affect weight. Our specialists create a personalized plan to help you lose weight, improve your metabolic health and maintain your progress over time.  

Your care begins with a comprehensive evaluation of your health, weight history, goals and previous treatments. Our multidisciplinary team then helps you compare appropriate options — including lifestyle and nutrition support, FDA-approved weight loss medications, minimally invasive endoscopic procedures and metabolic and bariatric surgery. Because these services are coordinated within one academic medical center, your plan can evolve as your needs change. 

We offer medical weight loss and obesity treatment across the full continuum of care. Options may include nutrition and behavioral counseling, medically supervised weight loss, GLP-1 and other prescription weight loss medications, bariatric endoscopy, sleeve gastrectomy, gastric bypass and revisional bariatric procedures. We also evaluate weight regain, side effects or complications after a previous weight loss procedure and develop a tailored next-step plan.  

Weight and metabolic health affect the entire body. Our team addresses obesity-related conditions such as type 2 diabetes, high blood pressure, obstructive sleep apnea, gastroesophageal reflux disease (GERD), high cholesterol and metabolic liver disease. Bariatric surgeons, obesity medicine and nutrition specialists, bariatric endoscopists, endocrinologists, gastroenterologists, dietitians, behavioral health clinicians and other specialists collaborate when needed to provide coordinated care. 

A patient navigator helps you understand the next steps, connect with the right specialists and coordinate follow-up care. Whether you are exploring treatment for the first time, considering GLP-1 medications or weight loss surgery, or looking for help after a previous procedure, we meet you without judgment and help you make an informed decision.

Medical and Surgical Weight Loss Services We Offer

There is no single treatment that is right for everyone. We offer a complete range of evidence-based weight management services and help you choose an approach based on your health, weight history, goals, preferences and previous treatment experience.

Your first visit is an opportunity to understand your options. Some patients benefit from one treatment, while others use a combination or move between treatments over time.

Which Weight Loss Treatment Is Right for Me?

The best starting point depends on your medical history, body mass index (BMI), weight-related conditions, prior treatments and personal goals. Our team will evaluate you and explain which options may be safe and effective. Treatment recommendations and insurance requirements vary by patient and health plan.

Lifestyle and Behavioral Program 

This may be a good starting point if you want structured support with eating patterns, physical activity, sleep, stress and the behaviors that influence long-term weight management. It can be used alone or alongside medication, endoscopy or surgery. 

Endocrinology 

An endocrinology evaluation may be helpful if diabetes, thyroid disease, hormonal concerns or another metabolic condition may be affecting your weight or treatment plan. 

Prescription Weight Loss Medications and Injections 

FDA-approved weight loss medications, including GLP-1 and GIP/GLP-1 therapies, may be considered for eligible patients who need additional help reducing appetite, losing weight or improving metabolic health. Our clinicians review benefits, side effects, medical history and long-term treatment considerations with you. 

Bariatric Surgery 

Metabolic and bariatric surgery may be appropriate for patients seeking the most effective and durable treatment for obesity, particularly when weight-related conditions are present or nonsurgical treatments have not produced sufficient, lasting improvement. Our surgeons offer minimally invasive procedures and individualized guidance on eligibility, benefits and risks. 

Bariatric Endoscopy Procedures 

Endoscopic weight loss may be an option if you want a minimally invasive, nonsurgical procedure or need treatment for weight regain after bariatric surgery. Procedures are performed through the mouth, without external incisions, under general anesthesia; eligibility depends on your anatomy, health and treatment history.
