What Can Disqualify You From Bariatric Surgery? Medical & Eligibility Factors
Brian Chin
Bariatric surgery can be life-changing, helping patients achieve significant weight loss, improve obesity-related conditions, and enhance quality of life. However, not everyone qualifies right away.
Understanding what can disqualify you from bariatric surgery—and why those factors matter—can help you prepare, address barriers, and explore safe alternatives if needed.
At BASS Bariatric Surgery Center, we believe informed patients make better long-term decisions.
Why Bariatric Surgery Eligibility Matters
Eligibility guidelines are not designed to exclude patients arbitrarily. They exist to:
- Protect patient safety and reduce surgical risk
- Improve long-term weight-loss outcomes
- Ensure patients are physically and emotionally prepared
- Maximize benefits such as diabetes remission and improved heart health
Meeting eligibility criteria helps set the foundation for success before surgery even begins.
Common Factors That May Disqualify You From Bariatric Surgery
Only a bariatric surgeon can make a final determination, but the following factors may affect candidacy.
1. BMI That Does Not Meet Requirements
Most bariatric programs require:
- BMI ≥ 40, or
- BMI ≥ 35 with obesity-related conditions such as diabetes, sleep apnea, or hypertension
Patients below these thresholds may be advised to pursue non-surgical weight-loss options.
2. Age-Related Considerations
Many programs have general age guidelines:
- Typically not under 16
- Often cautious above 70–75, depending on health status
Age alone does not automatically disqualify someone, but risks increase at the extremes and require careful evaluation.
3. Active Substance Abuse
Ongoing alcohol or drug misuse can:
- Interfere with healing
- Increase complication risks
- Affect long-term outcomes
Most programs require documented sobriety before surgery is approved.
4. Uncontrolled Medical Conditions
Certain conditions may delay or disqualify surgery if not well managed, including:
- Severe heart disease
- Advanced lung or respiratory disease
- Poorly controlled diabetes
- Serious blood clotting or autoimmune disorders
These conditions do not always mean surgery is impossible—but they may require treatment and specialist clearance first.
5. Psychological Readiness Concerns
A psychological evaluation is a standard part of bariatric surgery preparation.
Surgery may be delayed if a patient has:
- Untreated eating disorders
- Severe, unmanaged mental health conditions
- Inability to follow post-operative guidelines
With treatment and support, many patients later become eligible.
6. Inability to Commit to Post-Surgery Care
Bariatric surgery requires lifelong changes, including:
- Dietary modifications
- Vitamin and mineral supplementation
- Regular follow-up visits
Patients unwilling or unable to commit to these requirements may be advised to postpone surgery.
Can You Improve Your Chances of Qualifying?
Yes. Many disqualifying factors are temporary or modifiable.
Your care team may recommend:
- Treating underlying medical conditions
- Completing a supervised weight-loss program
- Attending nutrition and education classes
- Undergoing counseling or psychological support
- Meeting insurance documentation requirements
Eligibility is often a process, not a single yes-or-no decision.
What If You’re Denied Bariatric Surgery?
Being denied does not mean your weight-loss journey is over.
A bariatric specialist can help you explore:
- Medical weight-loss programs
- Prescription weight-loss medications
- Lifestyle-based interventions
- Future re-evaluation for surgery
Frequently Asked Questions
Can you be denied bariatric surgery?
Yes. Surgery may be denied if risks outweigh benefits or if required criteria are not met.
Do mental health conditions disqualify you?
Not automatically. With proper treatment and support, many patients still qualify.
What BMI do you need for bariatric surgery?
Typically BMI ≥ 40, or BMI ≥ 35 with obesity-related health conditions.

Bariatric surgery eligibility is about safety, readiness, and long-term success—not judgment. While some factors can temporarily disqualify you, many patients can address these issues and qualify later.
