Weight Loss Surgery to Help With Obesity.

Obesity is more than just a weight problem. It can cause life-threatening medical conditions, such as high blood sugar, hypertension, and sleep apnea.

By conducting proper patient assessment and examinations, the Khalili Center’s surgeons can prescribe the best surgical option for you.

We specialize in minimally-invasive, single-incision, and robotic bariatric surgery that usually involves small incisions only. Weight loss surgery or bariatric surgery targets the digestive system to help induce significant weight loss.

Obesity Treatments.

With the Khalili Center’s record of over 8,000 successful weight loss surgeries, we believe that the solution to obesity begins with the appropriate weight loss procedure.

The Khalili Center offers several weight loss surgery options to individuals with obesity. The types of bariatric surgery choices we provide include the following:


Gastric Bypass Surgery

This surgery option is one of the most common types of weight loss surgeries in the US. Surgeons create two unequal portions of the stomach, resulting in a dramatic restriction of the amount of food you can eat or desire to consume.

The surgery also modifies the size of the stomach, such that the organ decreases the absorption of calories and food. This malabsorption means feeling satisfied quickly after eating small meals.

This type of surgery may result in risks, such as the leaking of digestive juices and partly-digested food. This is why it is essential to entrust your operation to experts, such as the Khalili Center’s surgeons.

Sleeve Gastrectomy

Gastric sleeve surgery is also called vertical sleeve gastrectomy. This laparoscopic procedure creates a gastric sleeve, or a narrow tube, separate from the larger portion of the stomach. This partition helps empty food out of the bottom of the stomach into the small intestine.

The new stomach is smaller and does not create the same appetite-increasing gut hormones, such as ghrelin, as the regular stomach. Hence, after laparoscopic¬†sleeve gastrectomy¬†with the Khalili Center, your appetite dramatically reduces.¬†The American Society of Colon and Rectal Surgeons defines laparoscopic surgeries as specialized surgery techniques that are minimally invasive(1).Can’t find an exact match to any of the keywords

Unlike gastric bypass surgeries that require intestinal re-routing, sleeve gastrectomy is a less complicated procedure. The surgery allows you to lose a significant amount of weight because of the decreased food intake.

LAP-BAND¬ģ Surgery

This gastric band over surgery involves placing a LAP-BAND¬ģ device around the top part of the stomach. The adjustable gastric banding device creates a two-compartment stomach, resulting in a person eating enough food only to fill the stomach‚Äôs top part.

After a LAP-BAND surgery, the stomach‚Äôs upper, small pouch can hold only about half a cup of food, so clients feel full faster and satisfied longer. The US Food and Drug Administration (FDA) backs the use of the LAP-BAND¬ģ, a gastric band brand(2).

Revisional Procedures

Weight loss operations are generally successful in reducing excess weight. However, some surgical procedures require revisions due to device-related issues or lack of long-term weight loss.

After sleeve gastrectomy, some patients may suffer from heartburn. Outdated and restrictive procedures, such as stapled gastroplasty, may result in anatomic and nutritional issues.

In these situations, one would need the help of an experienced bariatric surgeon to revise these outdated or detrimental procedures. The Khalili Center specializes in revision weight loss surgery.

How to Know if a Weight Loss Procedure Is Right for You?

At the core of the Khalili Center is the partnership between doctors and patients. Before prescribing a weight loss program or procedure, doctors should first assess your healthcare needs, weight loss goals, and expectations.

Weight loss is a journey unique to each of our patients. No single procedure or diet program can cure obesity.

Our approach is multidisciplinary, assuring patients that they can get the most comprehensive care available.

How to Choose the Best Surgeon

The Khalili Center’s team of weight loss surgeons includes some of the best and brightest surgeons in Los Angeles, CA. With a competent team like ours, even medical professionals suffering from obesity go to our weight loss center for surgery.

Theodore Khalili, MD, FACS, is the founder and Director of the Weight Loss Surgery of Southern California Center.

All of the Khalili Center’s competent surgeons share this vision. We believe that any of our surgeons can help you begin your weight loss journey safely and effectively.

We Care for Our Patients

We offer free insurance verification for you to know if your insurance coverage can pay for your surgery. Most insurance companies cover the surgery costs of obese patients with a body mass index (BMI) of 35 and above.

To help with concerns on surgery costs, the Khalili Center also offers financing through Prosper Healthcare Lending, an esteemed financing company in the healthcare industry. This firm has empowered over 250,000 people by lending over $3 billion in costs borrowed.

Risks of Undergoing Weight Loss Surgery

Bariatric surgery is considered one of the safest surgical procedures for weight loss. However, it may have side effects, such as the dumping syndrome, the increased risk of developing kidney stones, the likelihood of not losing the desired body weight, or regaining weight(3).

Dumping syndrome happens when the stomach empties its contents into the first part of the small intestine faster than average(4).

Bariatric surgery is safe in general. To learn about the safest weight loss surgery option, you should request a comprehensive assessment from the Khalili Center’s top surgeons.

Life After Weight Loss Surgery

For some medical centers, successful surgery is the end goal. At Khalili Center, successful surgery is merely the beginning; we’re all about success stories.

Located in Beverly Hills, the Khalili Center is designed to welcome bariatric patients and inspire them.

Large, bright, and relaxing spaces with modern accents reflect our practice’s ease, openness, and convenience.

The Khalili Center has a Unique Care Support Program available to patients before and after surgery.

Best-in-class patient care means working with registered dieticians, psychologists, and general doctors. These collaborations help with a patient’s recovery time and shorten their hospital stay.

These partnerships also gradually ease these patients into post-surgical lifestyle changes and weight management.

The Khalili Center aims to foster a supportive community that welcomes our clients even before surgery.

Registered dietitians recommend healthy food and provide health information. Meanwhile, psychologists with doctorate degrees offer private counseling sessions to prepare patients for life after bariatric surgery procedures.

Patients are encouraged to join support groups before surgery and after bariatric procedures. These sessions aim to inspire fellow weight loss surgery patients.

Events involving fellow patients and doctors are planned throughout the year to keep clients active and social. Programs, such as monthly walks with doctors and regular follow-ups post-surgery, assure patients of our support beyond surgery.
