Criteria for Bariatric Surgery: Are You a Candidate?

Bariatric surgery is no longer a one-size-fits-all solution reserved for only the most severe cases of obesity. With advancements in treatment and updated insurance policies, more people than ever before now qualify. This blog breaks down the evolving criteria for bariatric surgery, how BMI fits into the equation, and what to expect once you qualify.

Traditional Criteria: The BMI Threshold

For many years, bariatric surgery was reserved for two types of patients:

  • Those with a BMI of 35–40 and at least one obesity-related medical condition
  • Those with a BMI of 40 or higher, regardless of other health issues

These medical conditions—often called “qualifying comorbidities”—include:

  • Hypertension
  • Type 2 Diabetes
  • Fatty Liver Disease
  • Sleep Apnea
    … and other weight-related health problems.

BMI, or Body Mass Index, is a number calculated from your weight and height. While not a perfect measure, it’s widely used to determine eligibility for surgery. 

Use our BMI calculator below to determine if you lie within the range: 

BMI 40 and Above: Automatic Qualification

If your BMI is 40 or higher, you generally automatically qualify for bariatric surgery—no additional medical conditions required. This threshold remains one of the most recognized criteria across both public and private insurers.

The Rise of GLP-1 Medications and Shifting Criteria

The growing popularity of GLP-1 medications (like Ozempic and Wegovy) for weight loss has shifted the conversation.

Why does this matter?

  • Insurance companies are recognizing that long-term use of these medications can cost as much or more than bariatric surgery.
  • A recent study showed that just 9 months on GLP-1 meds equals the cost of one bariatric procedure.
  • Many patients eventually regain weight once they stop taking GLP-1s due to cost, side effects, or limited access.

This has led to a lowering of BMI requirements by some insurance providers. In many cases now:

Patients with a BMI as low as 30—combined with a medical condition—can qualify for surgery.

If you’re considering surgery, the most reliable way to know your status is to:

  • Review your insurance policy
  • Contact your provider directly to confirm current criteria

 

Self-Pay Patients: International Guidelines Apply

For those paying out of pocket, the eligibility criteria are based on global medical guidelines, which now recognize:

A BMI of 30 or above with a related medical condition qualifies for bariatric surgery.

Our self-pay fee is less than $10,000—making it a cost-effective alternative to long-term GLP-1 medications. In fact, within 9 to 10 months, the cost of bariatric surgery can equal the cumulative expense of GLP-1 treatments, but without the ongoing financial burden those medications often bring.

According to international bariatric authorities like ASMBS and IFSO, patients with a BMI of 30 or higher benefit significantly from surgery. So, if you’re a self-pay patient—or if your insurance allows Dr. Amit Taggar to determine the qualifying BMI—you’re likely eligible under these globally recognized standards.

Whether you’re insured or self-paying, chances are you may already meet the new, more inclusive criteria.

What Happens After You Qualify?

Once your BMI and insurance criteria are met, your next step is a consultation with Dr. Amit Taggar—either in person or virtually.

This consultation is about more than just choosing a surgery. It’s about building a plan tailored to you.

  • A patient with a BMI of 60 and no major health concerns will need a different approach than one with a BMI of 40 and diabetes.
  • Patients with severe acid reflux, for example, may be better suited to specific procedures over others.

That’s why Dr. Taggar offers a full range of surgeries:
Sleeve Gastrectomy, Gastric Bypass, Duodenal Switch, Single Anastomosis Duodenal Switch (SADI), and Revision Surgeries.

The operation is matched to your needs, not limited by the surgeon’s preference.

Insurance Timelines: Not All Policies Are the Same

Even if you qualify medically, your insurance plan may impose different wait times before authorizing the procedure:

  • Some plans require no waiting period or just one doctor’s visit
  • Others demand 3, 6, or even 12 months of documented supervised weight-loss attempts

Dr. Taggar and his team will create a custom schedule to meet your insurer’s guidelines—and ensure no time is wasted.

Final Thoughts: Qualification Is Just the Beginning

Meeting the necessary requirements is just the first step—once eligible, patients can look forward to the many life-changing benefits of undergoing bariatric surgery, from improved metabolic health to enhanced quality of life.

Whether your BMI is 40+ or you’re newly eligible under updated guidelines, the next steps include personalized evaluations, nutrition planning, and lifestyle coaching.
