Why More Patients Are Choosing Gastric Sleeve in San Diego
Gastric sleeve surgery (also called sleeve gastrectomy) is the most popular weight loss procedure in San Diego—and for good reason. It’s safe, effective, minimally invasive, and offers excellent weight loss results with fewer complications than older procedures.
- Removes about 80% of the stomach to reduce hunger and portion sizes
- Preserves normal digestion (no intestinal rerouting)
- Helps patients lose 50–70% of excess weight
- Shorter surgery time and recovery compared to gastric bypass
- Proven to improve or resolve diabetes, high blood pressure, sleep apnea, and more
Dr. Barnes has performed hundreds of successful gastric sleeve surgeries and provides each patient with a tailored pre- and post-op plan to support long-term success.

Bariatric Surgery Options
We offer a full spectrum of bariatric procedures to fit your medical needs and weight loss goals.
Gastric Sleeve Surgery (Sleeve Gastrectomy)
The best choice for many patients, gastric sleeve surgery is simple, safe, and incredibly effective. By permanently reducing the size of your stomach, it helps you feel full with less food—while keeping digestion natural and nutrient absorption intact.
- Ideal for most patients with a BMI of 35 or higher
- Fast recovery and low risk of long-term complications
- No foreign devices or intestinal rerouting
Gastric Bypass Surgery
This procedure changes both your stomach size and the path food takes through your digestive system, helping you absorb fewer calories. It’s especially helpful for patients with type 2 diabetes or severe GERD.
- Significant weight loss potential (60–80% of excess weight)
- Effective for obesity-related conditions
- Laparoscopic approach for reduced downtime
Lap-Band Surgery In San Diego (Adjustable Gastric Band)
Lap-Band is a less invasive option where a silicone band is placed around the upper stomach. It restricts food intake and can be adjusted over time or removed if needed.
- Reversible and adjustable
- No cutting or stapling of the stomach
- Best for patients looking for a lower-risk option
Is Bariatric Surgery Right for You?
You may be a candidate for weight loss surgery if you:
- Have a BMI over 40
- Have a BMI over 35 with health conditions such as diabetes, high blood pressure, or sleep apnea
- Have not been successful with traditional diet and exercise
- Are motivated to make long-term lifestyle changes
Dr. Barnes provides a thorough consultation to determine the best surgical approach for your unique health profile.
