Obesity is one of the fastest-growing health challenges in Kenya. With over 13% of Nairobi adults classified as obese and the number rising each year, access to safe, affordable, and effective weight loss solutions has never been more important. Whether you are exploring non-surgical options or considering permanent bariatric surgery, this guide covers every treatment available in Nairobi in 2025 — with honest guidance on who each option is right for, what results to expect, and what it costs.
What Is Bariatric Surgery — and Do You Need It?
Bariatric surgery is a collective term for surgical procedures that help people lose significant weight by modifying the digestive system. The most common procedures in Kenya include the gastric sleeve, gastric bypass, and the newer SADI-S procedure. These are highly effective tools for people with a BMI of 35 or above, especially those living with type 2 diabetes, high blood pressure, or sleep apnoea.
However, surgery is not the only path to lasting weight loss. Thanks to significant advances in medical technology, patients in Nairobi now have access to powerful non-surgical alternatives — including the Allurion swallowable balloon, the endoscopic gastric balloon, and Mounjaro (tirzepatide) injections — that can help you lose 10–22% of your body weight without an operating theatre.
The "best" weight loss procedure depends on your BMI, health history, lifestyle, and goals. A consultation with a qualified bariatric specialist is always the best first step — and at Rayhaan Healthcare, your initial consultation is completely free.

Gastric Sleeve Surgery in Kenya: What You Need to Know
The laparoscopic gastric sleeve (also called a sleeve gastrectomy) remains the most commonly performed bariatric surgery in Kenya. The procedure involves removing approximately 75–80% of the stomach, leaving a narrow, sleeve-shaped pouch about the size of a banana. This dramatically reduces hunger hormones (particularly ghrelin) and limits the amount of food you can eat in one sitting.
Who Is a Good Candidate?
- Adults with a BMI of 35 or above
- Adults with BMI 30–35 and at least one obesity-related condition (diabetes, hypertension, joint pain)
- Those who have tried diet and exercise programmes without sustained success
- Patients who are medically cleared for surgery after assessment
What Results Can You Expect?
Most patients lose 25–35% of their total body weight within 12–18 months of gastric sleeve surgery. For someone weighing 120 kg, that could mean losing 30–42 kg. Beyond the scale, patients typically see significant improvements in type 2 diabetes, blood pressure, cholesterol, joint pain, and sleep quality.
Gastric sleeve is a permanent, irreversible procedure. It is essential that it is performed by a board-certified bariatric surgeon with proven experience. At Rayhaan Healthcare, all surgical procedures are conducted by our consultant bariatric surgeons, Dr. Mustafa Alibhai and Dr. Taha, at Park Medical Centre, Parklands.
Non-Surgical Weight Loss in Nairobi: The Modern Alternatives
Not everyone is ready for — or needs — surgery. Rayhaan Healthcare is proud to be one of the only clinics in Kenya offering the full spectrum of non-surgical weight loss technologies, including options only recently available in Nairobi.
The Allurion Balloon — No Endoscopy, No Anaesthesia
The Allurion Programme is a genuine breakthrough. It is the world's first gastric balloon that requires no endoscopy and no anaesthesia whatsoever. You simply swallow a small capsule during a routine 20-minute clinic visit. Using a thin catheter, the capsule is then inflated with water until it is roughly the size of a grapefruit. After approximately 16 weeks, the balloon's valve opens naturally, it deflates, and passes out of the body on its own. The programme includes digital coaching via an app and remote check-ins with our nutrition team.
Mounjaro (Tirzepatide) in Nairobi — A Medical Breakthrough
Mounjaro is the brand name for tirzepatide — a weekly injectable medication originally developed for type 2 diabetes that has shown remarkable results for weight loss. It works by activating both GIP and GLP-1 receptors, simultaneously reducing appetite, slowing gastric emptying, and improving insulin sensitivity. In the landmark SURMOUNT-1 clinical trial, participants lost an average of 22.5% of their body weight — results that rival many surgical procedures.
At Rayhaan Healthcare, our Mounjaro programme combines weekly supervised injections with nutritional coaching, fitness support, and regular blood monitoring — all delivered from our Parklands clinic.
Multiple randomised controlled trials support the safety and efficacy of both tirzepatide (Mounjaro) and endoscopic balloon therapy for weight loss. For peer-reviewed research, see the sources listed at the end of this article.
