Gastric Bypass Surgery with Dr. Lance Mayabi
Dr. Lance Mayabi, Bariatric & Endoscopic Weight Loss Specialist, Nairobi
Transform Your Life with Gastric Bypass Surgery
Gastric Bypass Surgery is a proven and effective weight loss procedure designed for individuals struggling with obesity. By reducing the stomach size and altering the digestive system, this surgery helps patients achieve long-term weight loss and improved overall health.
What is Gastric Bypass Surgery?
Gastric bypass, also known as Roux-en-Y Gastric Bypass (RYGB), is a bariatric procedure that involves creating a small stomach pouch and rerouting a portion of the small intestine. This process limits food intake, reduces calorie absorption, and alters hunger hormones to support sustainable weight loss.
Benefits of Gastric Bypass Surgery
-
Significant Weight Loss – Patients typically lose 60-80% of excess body weight within the first two years.
-
Improved Health Conditions – Helps in the management or resolution of conditions such as type 2 diabetes, hypertension, sleep apnea, and high cholesterol.
-
Enhanced Quality of Life – Increased mobility, better self-confidence, and a healthier lifestyle.
-
Long-Term Success – With the right post-surgery care, patients can maintain a healthy weight for a lifetime.

Who is a Candidate?
Gastric bypass may be the right option if you:
-
Have a BMI of 40 or higher, or BMI of 35+ with obesity-related health conditions.
-
Have tried other weight loss methods without long-term success.
-
Are committed to making lifelong dietary and lifestyle changes.
-
Do not have medical conditions that contraindicate surgery.
The Procedure
Pre-Surgery Preparation – Comprehensive evaluations, nutritional counseling, and medical assessments.
Surgery Day – A minimally invasive laparoscopic procedure is performed under general anesthesia.
Recovery Phase – Patients typically stay in the hospital for 1-2 days and gradually transition to a specialized diet.
Post-Surgery Support – Regular follow-ups, dietary guidance, and lifestyle counseling for sustained results.
