Meet Some of Our Patients Who Underwent Gastric Sleeve Surgery
What Are the Medical Qualifications for Gastric Sleeve Surgery?
The gastric sleeve qualifications are based on international medical guidelines from major health organizations. These guidelines use a tool called the Body Mass Index (BMI) to determine medical necessity. BMI is a calculation of your weight in relation to your height.
As surgeons, we follow this standard of care to ensure patient safety. The primary medical qualifications are:
- A BMI of 40 or higher (Class III or “Severe” Obesity).
If your BMI is 40 or above, you generally qualify for bariatric surgery based on this number alone, as this level of obesity is considered a serious, independent health risk. - A BMI of 35 to 39.9 (Class II Obesity) *WITH* at least one serious health condition.
If your BMI is in this range, you qualify if you also suffer from one or more significant “co-morbidities”—health problems that are caused or made worse by obesity.
These qualifying health conditions are very common and are a primary reason why patients seek surgery. They include:
- High Blood Sugar (Type 2 Diabetes)
- High Blood Pressure (Hypertension)
- High Cholesterol (Hyperlipidemia)
- Severe Obstructive Sleep Apnoea
- Severe Joint Pain (Osteoarthritis)
- Fatty Liver Disease (NAFLD or NASH)
In fact, having a condition like high blood sugar (Type 2 diabetes) makes you an *even stronger* candidate, as gastric sleeve surgery is a powerful metabolic procedure that can lead to its remission. As a surgeon with over two decades of experience, Prof. Dr. Karatepe often explains that we are not just treating weight; we are treating these life-threatening diseases.
What is the BMI qualification for gastric sleeve?
The primary gastric sleeve qualification is a Body Mass Index (BMI) of 40 or higher (severe obesity). You can also qualify with a BMI of 35 to 39.9 if you also have at least one serious weight-related health condition, such as high blood sugar (type 2 diabetes) or high blood pressure.

Beyond BMI: The Other Key Gastric Sleeve Qualifications
Your BMI is only the first step. Obesity is a complex disease, and a successful, long-term outcome depends on more than just a stomach reduction surgery. The gastric sleeve is a powerful tool, but *you* are the most important part of the equation. This is why a full bariatric evaluation also includes these crucial qualifications.
1. A History of Failed Diet Attempts
Bariatric surgery is not a “first resort.” To qualify, you must be able to show that you have made serious, documented attempts to lose weight through traditional methods like diet and exercise. This confirms that your obesity is a persistent, chronic disease (morbid obesity) that has not responded to other treatments, making a surgical intervention medically necessary.
2. Psychological & Mental Readiness
This is a standard and vital part of the gastric sleeve qualifications. You will have a supportive conversation with a psychologist. This is not a “test” you can fail. The goal is to ensure you are in a good mental space to handle the significant life changes that follow surgery. The evaluation checks for:
- A clear understanding of the risks and benefits.
- A stable mental health status (e.g., any depression or anxiety is well-managed).
- No active, untreated eating disorders (like binge eating disorder).
- No active drug or alcohol addiction.
Our goal is to identify any areas where you might need *extra* support to succeed.
3. Commitment to Lifelong Change (The Most Important Qualification)
The surgeon and patient must be partners. You must be willing and able to commit to permanent lifestyle changes. This is non-negotiable for long-term health. This commitment includes:
- Following the post-op diet perfectly to allow for healing.
- Adhering to your new lifelong diet (protein-first, small portions).
- Taking your bariatric-specific vitamins every day for the rest of your life.
- Attending all your medical follow-up appointments.
4. Quitting Smoking (A Non-Negotiable Safety Rule)
This is a hard-stop safety qualification. You must quit smoking, vaping, and all nicotine use for at least 6-8 weeks before your surgery. Smoking dramatically reduces blood flow and oxygen to your tissues, which are trying to heal. It massively increases your risk of serious gastric sleeve complications like staple line leaks, blood clots, and pneumonia.
What can disqualify you from getting a gastric sleeve?
You can be disqualified or postponed from gastric sleeve surgery if you have an active drug or alcohol addiction, an untreated severe psychological condition (like an active eating disorder), or if you are unable or unwilling to quit smoking. Your inability to commit to the required lifestyle changes is also a disqualifier.
Why Choose Prof. Dr. Oguzhan Karatepe for Your Bariatric Evaluation?
Meeting the gastric sleeve qualifications is not just a checklist; it is the start of a professional medical evaluation. Your surgeon’s experience is critical in determining not only *if* you qualify, but *which* weight loss surgery is the safest and best choice for your unique health profile (e.g., sleeve vs. bypass).
Prof. Dr. Oguzhan Karatepe is a leading figure in bariatric surgery, bringing over 25 years of specialized experience to every patient. With more than 3,000 successful surgeries performed and hundreds of academic publications, his expertise is not just clinical; it is academic. As a Professor of Surgery, he has a deep, authoritative understanding of the complex metabolic conditions (like high blood sugar) that qualify patients for surgery.
His mastery of advanced laparoscopic and robotic surgery means that once you are cleared, your procedure is performed with the utmost precision. This minimally invasive “keyhole” approach is the gold standard for a safe procedure and a fast gastric sleeve recovery. Our expert team is here to help you with personalized surgical solutions, starting with a world-class evaluation.
How to choose the right gastric sleeve surgeon?
Gastric sleeve surgery is performed by a bariatric surgeon, who is a general surgeon with specialized fellowship training in weight loss procedures. When choosing, you must verify their credentials, look for extensive experience (1,000+ procedures), and ensure they operate in an accredited, high-tech hospital. A strong aftercare program is essential.

Frequently Asked Questions (FAQ) About Gastric Sleeve Qualifications
Q: What is gastric sleeve surgery?
A: Gastric sleeve surgery is a weight loss operation where a surgeon removes about 75-80% of the stomach. This leaves a small, banana-shaped “sleeve,” which restricts food intake and reduces hunger hormones, helping you lose weight effectively.
Q: What is the minimum BMI for gastric sleeve?
A: The minimum gastric sleeve qualification is typically a BMI of 35, but only if you also have a serious weight-related health problem like high blood sugar or severe sleep apnoea. If you have no other health issues, the minimum BMI is 40.
Q: Is there an age limit for gastric sleeve?
A: While most bariatric patients are between 18 and 65 years old, there is no strict “age limit.” For patients over 65, the decision is based on your overall “physiologic age” (how healthy you are), not your chronologic age. A full cardiac and pulmonary clearance is required.
Q: Do I have to quit smoking to qualify?
A: Yes, absolutely. This is a non-negotiable gastric sleeve qualification for patient safety. Smoking dramatically increases your risk of a staple line leak, blood clots, and pneumonia. You must be smoke-free for at least 6-8 weeks before your surgery date.
Q: Do I qualify if I have high blood sugar (diabetes)?
A: Yes. In fact, it makes you a *stronger* candidate. Gastric sleeve surgery is a highly effective treatment for Type 2 diabetes, often leading to remission. Having a BMI of 35+ *with* diabetes is a primary qualification.
Q: Is the pre-op diet a qualification?
A: Yes, in a way. The gastric sleeve pre-op diet is a critical safety step to shrink your liver. Your *ability and willingness* to follow this diet is a key qualification that shows your commitment and makes the surgery physically safer to perform.
Q: What happens during the psychological evaluation?
A: This is a supportive conversation, not a “test.” A psychologist will talk to you about your weight history, your motivations, your support system, and any history of depression, anxiety, or emotional eating. The goal is to identify any areas where you might need extra support to succeed after surgery.
Q: Can I qualify if I have a low BMI (e.g., BMI 30-34)?
A: In some cases, yes. While it is “off-label” from the standard gastric sleeve qualifications, patients with a BMI of 30-34 *plus* a severe, uncontrolled metabolic condition (like Type 2 diabetes) may be considered. This is evaluated on a case-by-case basis by an expert surgeon.
Q: What tests are needed to qualify for gastric sleeve?
A: To ensure you are a safe candidate, you will need a full pre-operative workup. This includes comprehensive blood tests (to check for nutritional deficiencies, thyroid issues, etc.), an EKG (heart check), a chest X-ray, and often an endoscopy (a camera test to look inside your stomach).
Q: Can I qualify if I’ve had previous stomach surgery?
A: This depends on the type of surgery. If you have had a C-section or gallbladder removal, it is not a problem. If you have had previous stomach surgery (like for a hiatal hernia or ulcer), you may still qualify, but it requires a highly experienced bariatric surgeon like Prof. Dr. Karatepe to handle the complexity of the scar tissue.
