Am I a Candidate for Weight Loss Surgery?
One of the first questions every patient asks is: “Do I qualify?” Candidacy for bariatric surgery depends on more than just your weight — it involves your overall health, your history with weight loss, your psychological readiness, and your commitment to lifelong change.
Dr. Carlos Navarrete has helped hundreds of patients determine whether surgery is the right path for them. This guide walks you through the medical criteria, the readiness factors, and an interactive assessment you can complete right now.
Step 1 — Calculate Your BMI
BMI is the primary screening tool for bariatric surgery eligibility. Enter your measurements below to see where you stand.

Candidacy Criteria
BMI Requirements in Detail
BMI is the primary initial screening tool, but it’s not the only factor. Understanding which BMI category you fall into — and what additional conditions apply — helps clarify your eligibility before your consultation.
Candidacy Criteria
Obesity-Related Health Conditions
Having one or more of these conditions strengthens your candidacy — particularly if your BMI is 35–39.9. These are also the conditions most likely to improve or resolve after surgery, making the risk-benefit calculation clearly favorable.
- Type 2 diabetes (especially uncontrolled)
- Prediabetes
- Metabolic syndrome
- High cholesterol / triglycerides
- Non-alcoholic fatty liver disease
- High blood pressure
- Heart disease or stroke history
- Obstructive sleep apnea
- Obesity hypoventilation syndrome
- Asthma worsened by weight
- Osteoarthritis (knees, hips, back)
- Degenerative disc disease
- PCOS or weight-related infertility
- Severe GERD or hiatal hernia
- Urinary stress incontinence
Candidacy Criteria
Psychological Readiness
Psychological readiness is just as important as physical health for long-term success. Surgery is a tool — and like any tool, it only produces results when used correctly. Dr. Navarrete looks for patients who understand this deeply.
- Realistic expectations — understands surgery is a tool, not a cure
- Intrinsic motivation (doing it for yourself)
- Willingness to make permanent changes
- Stable mental health or well-managed conditions
- Adequate coping skills for stress
- Support system in place
- History of mental health issues is fine if currently stable
- Active, untreated severe depression
- Uncontrolled bipolar or schizophrenia
- Active substance abuse
- Unrealistic expectations (perfection or instant results)
- External pressure (being pushed by a partner)
- Active, untreated eating disorders
- Inability to understand risks and requirements
Candidacy Criteria
Age Considerations
The standard candidacy range is 18–65, but age alone rarely disqualifies a patient. Dr. Navarrete evaluates patients outside this range individually.
- Excellent healing and recovery
- Maximum years to benefit
- Fewer existing complications
- Lifetime of dietary restrictions ahead
- Wait 18 months post-surgery before pregnancy
- Long-term vitamin compliance critical
- Balance of good health and long benefit horizon
- Often have comorbidities that will resolve
- Mature decision-making
- Balancing surgery with work/family
- More established eating patterns to change
- Health improvement extends quality of life
- Reduces medications
- Increases mobility and independence
- More thorough cardiac clearance needed
- Slower healing (still excellent outcomes)
- Must have good functional status
Candidacy Criteria
Contraindications
Certain conditions prevent surgery outright; others require evaluation and optimization first. The distinction matters — many “relative” contraindications can be resolved with preparation.
- Active cancer treatment
- Recent heart attack (within 6 months)
- Severe, uncontrolled heart failure
- Severe liver disease (cirrhosis)
- Severe lung disease preventing surgery
- Active psychosis or inability to consent
- Pregnancy
- Active, untreated drug or alcohol addiction
- Uncontrolled diabetes (optimize first)
- Severe heart disease (cardiac clearance needed)
- Significant lung disease (pulmonary clearance)
- Severe GERD (may need bypass instead of sleeve)
- Large hiatal hernia (repaired during surgery)
- Autoimmune disease on immunosuppressants
- Bleeding disorders (hematology clearance)
- Inflammatory bowel disease (Crohn’s, UC)

Frequently Asked Questions About Candidacy
What if my BMI is just under the requirement?
If you’re close — BMI 38–39 without comorbidities, or BMI 28–29 with uncontrolled diabetes — schedule a consultation anyway. Factors like weight distribution, muscle mass, severity of health conditions, and weight loss history can influence candidacy even when BMI falls slightly outside the typical range. Dr. Navarrete evaluates every case individually.
I have mental health issues — does that disqualify me?
Not automatically. Stable, treated mental health conditions don’t prevent surgery. What matters is current stability, adequate treatment, good coping mechanisms, and a support system. Very few mental health histories are truly disqualifying when properly managed. Discuss openly during your consultation.
I have diabetes — am I higher surgical risk?
Diabetic patients have slightly higher surgical risk, but the benefits almost always outweigh them. Diabetes frequently improves dramatically or resolves entirely after bariatric surgery — particularly with bypass. Careful blood sugar management before and during surgery reduces risk significantly. Dr. Navarrete specializes in diabetic bariatric patients.
I’ve had previous abdominal surgeries — does that prevent this?
No. Previous C-sections, appendectomy, gallbladder removal, hysterectomy, and similar procedures are not disqualifying. Scar tissue (adhesions) may make surgery slightly more complex, but experienced laparoscopic surgeons like Dr. Navarrete navigate this routinely. Disclose all previous surgeries during your consultation.
What if I can’t stop smoking?
Smoking cessation is required at least 4 weeks before surgery — it significantly increases the risk of leaks, infections, poor wound healing, and pulmonary complications. Most programs test for nicotine before surgery. If you’re struggling to quit, discuss cessation programs, nicotine replacement therapy (under guidance), and support resources with Dr. Navarrete’s team. Quitting is possible, and the team can help.
Will insurance cover my surgery with Dr. Navarrete?
About 50% of U.S. insurance plans cover bariatric surgery, but typically require months of documented supervised diet attempts, psychological evaluations, and prior authorizations. Self-pay with Dr. Navarrete in Tijuana typically costs less than most U.S. insurance out-of-pocket expenses — and bypasses the lengthy approval process entirely. Financing options are available.
I’m approved but nervous about committing — is that normal?
Completely normal. This is a major, permanent decision. Consider attending a support group, speaking with previous patients (Dr. Navarrete can connect you), or simply taking more time to reflect. Don’t rush — but also don’t let fear prevent you from making a change that could add years to your life. The consultation itself carries zero obligation.
