Obesity is a growing health concern in Kenya, affecting people of all ages and increasing the risk of serious medical conditions such as type 2 diabetes, high blood pressure, heart disease, sleep apnea, and joint problems. For individuals who have struggled to achieve lasting results through diet and exercise alone, gastric sleeve surgery offers a safe, effective, and life-changing solution.

At Dr. Lance Mayabi’s Bariatric & Metabolic Surgery Practice, we are committed to helping patients regain their health through evidence-based surgical care tailored to their unique needs.

What Is Gastric Sleeve Surgery?

Gastric sleeve surgery, medically known as Sleeve Gastrectomy, is one of the most commonly performed bariatric procedures worldwide. During the procedure, approximately 75–80% of the stomach is removed, leaving behind a narrow, sleeve-shaped stomach.

The smaller stomach allows patients to:

  • Feel full after eating smaller portions
  • Reduce hunger by lowering the production of the hunger hormone (ghrelin)
  • Develop healthier eating habits
  • Achieve significant and sustainable weight loss

Unlike gastric bypass surgery, gastric sleeve surgery does not reroute the intestines, making it a simpler procedure while still delivering excellent long-term results.

Who Is a Good Candidate for Gastric Sleeve in Kenya?

You may be a suitable candidate if you:

  • Have a Body Mass Index (BMI) of 35 or higher
  • Have a BMI of 30–34.9 with obesity-related health conditions, such as diabetes or hypertension
  • Have tried multiple weight-loss methods without lasting success
  • Are committed to making permanent lifestyle changes
  • Are medically fit for surgery after a comprehensive evaluation

Every patient undergoes a detailed assessment to determine whether gastric sleeve surgery is the most appropriate treatment.

Benefits of Gastric Sleeve Surgery

Significant Weight Loss

Most patients lose 60–70% of their excess body weight within 12 to 18 months when they follow recommended dietary and lifestyle guidelines.

Improved Overall Health

Weight loss often leads to improvement or remission of obesity-related conditions, including:

  • Type 2 diabetes
  • High blood pressure
  • High cholesterol
  • Obstructive sleep apnea
  • Joint and back pain
  • Fatty liver disease

Better Quality of Life

Patients frequently experience:

  • Increased energy levels
  • Improved mobility
  • Greater self-confidence
  • Enhanced mental well-being
  • Better participation in work, family, and social activities

How Gastric Sleeve Surgery Is Performed

The procedure is usually performed laparoscopically (keyhole surgery) using small incisions.

During surgery:

  1. Small incisions are made in the abdomen.
  2. Surgical instruments and a tiny camera are inserted.
  3. Approximately 75–80% of the stomach is removed.
  4. The remaining stomach is shaped into a sleeve.
  5. The incisions are closed carefully.

Laparoscopic surgery generally results in:

  • Less pain
  • Smaller scars
  • Faster recovery
  • Reduced risk of complications
  • Shorter hospital stay

Recovery After Gastric Sleeve Surgery

Recovery varies between individuals, but most patients can expect:

  • Hospital stay of 1–3 days
  • Return to light daily activities within 1–2 weeks
  • Gradual return to work depending on the nature of employment
  • Progressive dietary stages from liquids to soft foods and eventually solid meals

Regular follow-up appointments are essential to monitor recovery, nutrition, and long-term success.

Lifestyle Changes After Surgery

Gastric sleeve surgery is a powerful tool—but long-term success depends on healthy habits.

Patients are encouraged to:

  • Eat smaller, balanced meals
  • Stay well hydrated
  • Take prescribed vitamin and mineral supplements
  • Exercise regularly
  • Attend scheduled follow-up visits
  • Seek nutritional and psychological support when needed

These changes help maximize weight loss while maintaining overall health.

Risks and Safety

Like any surgical procedure, gastric sleeve surgery carries potential risks, including:

  • Bleeding
  • Infection
  • Leakage along the staple line
  • Blood clots
  • Vitamin deficiencies
  • Acid reflux in some patients

Fortunately, when performed by an experienced bariatric surgeon with appropriate preoperative assessment and postoperative follow-up, gastric sleeve surgery has an excellent safety profile.
