From surgical procedures like gastric sleeve and gastric bypass to non-surgical solutions like the Allurion balloon and Mounjaro — this guide covers every evidence-based weight loss option available right here in Nairobi, Kenya.
Quick Summary: Obesity affects millions of Kenyans and raises the risk of type 2 diabetes, hypertension, and heart disease. If diet and exercise alone have not produced lasting results, bariatric surgery or a medically supervised weight loss programme in Nairobi could be the solution you have been looking for.
Kenya is experiencing a rapid shift in disease burden. Urbanisation, sedentary lifestyles, and changing dietary patterns have pushed rates of overweight and obesity to record levels — particularly in Nairobi. For many patients, the consequences go far beyond cosmetic concerns. Obesity is directly linked to type 2 diabetes, hypertension, obstructive sleep apnoea, polycystic ovary syndrome (PCOS), non-alcoholic fatty liver disease, and several cancers.
The good news is that Nairobi is home to world-class bariatric and metabolic medicine specialists who offer the full spectrum of weight loss interventions — from the most advanced surgical techniques to the very latest non-surgical options. Whether you are researching for yourself or a loved one, this guide will help you understand every available pathway.
Bariatric surgery in Nairobi is performed by board-certified surgeons using minimally invasive laparoscopic techniques, meaning smaller incisions, faster recovery, and reduced risk compared to open surgery. Below are the main surgical procedures currently offered:
Around 80% of the stomach is removed, creating a narrow sleeve. This dramatically reduces hunger hormones (ghrelin) and limits food intake. The most commonly performed bariatric procedure worldwide.
Most Popular · PermanentA small gastric pouch is created and the small intestine is rerouted, reducing both capacity and calorie absorption. Highly effective for patients with type 2 diabetes.
High EWL · Metabolic BenefitsSingle Anastomosis Duodeno-Ileal Switch with Sleeve — a modern, single-loop variation of the duodenal switch that delivers superior weight loss results with fewer complications for super-obese patients.
Advanced · Super ObesityA silicone band is placed around the upper stomach to create a small pouch. Fully reversible and adjustable. Less commonly performed today as sleeve gastrectomy offers superior long-term results.
Reversible · AdjustableStandard international eligibility criteria for bariatric surgery include:
Not every patient needs or wants an operation. Endoscopic bariatric procedures are performed via the mouth using a flexible camera — there are no incisions, no general anaesthesia in most cases, and recovery is measured in days rather than weeks. These represent some of the most exciting advances in obesity surgery in Kenya.
The Endoscopic Gastric Sleeve in Nairobi (also called Endoscopic Sleeve Gastroplasty or ESG) is a truly procedure that replicates the effect of surgical sleeve gastrectomy without a single incision. A flexible endoscope is passed through the mouth into the stomach. The physician then uses an endoscopic suturing device to place a series of full-thickness sutures through the stomach wall, folding the stomach along its greater curvature to reduce its volume by approximately 70–80%.
Patients typically lose 15–20% of total body weight over 12–18 months. Because no tissue is removed, the procedure is technically reversible. Recovery is 2–3 days, and most patients resume normal activities within a week. ESG is particularly suitable for patients with a BMI of 30–40 who wish to avoid surgery.
The intragastric balloon is placed endoscopically into the stomach under mild sedation in a 20-minute procedure. Once positioned, it is inflated with saline to occupy space in the stomach, promoting early satiety and reducing the amount of food you need to feel full. The balloon remains in place for 6 months, after which it is removed endoscopically.
Combined with nutritional coaching and lifestyle support — as provided at Rayhaan Healthcare — patients can expect to lose 10–15% of their total body weight during the programme. Learn more about our Gastric Balloon programme →
The Allurion balloon (formerly Elipse balloon) is the world's first swallowable gastric balloon — no endoscopy, no sedation, no surgery. The balloon is swallowed as a capsule attached to a thin catheter. Once in the stomach, it is filled with 550ml of fluid through the catheter, which is then removed. After approximately 16 weeks, the balloon deflates naturally and passes out of the body. The entire process takes a single outpatient clinic visit of under 30 minutes.
Mounjaro (tirzepatide) is a once-weekly injectable medication that represents a landmark advancement in non-surgical weight management. It works by activating both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) receptors simultaneously — a dual mechanism no other weight loss medication has matched. The SURMOUNT clinical trial programme demonstrated average weight loss of up to 20.9% of body weight over 72 weeks.
Mounjaro is also highly effective for patients with type 2 diabetes, improving HbA1c alongside weight loss. At Rayhaan Healthcare's Mounjaro weight loss programme in Nairobi, treatment is supervised by a specialist physician with regular monitoring, dose titration, and dietitian support throughout.
Mounjaro should only be started under the supervision of a qualified physician. It is not suitable during pregnancy, or for patients with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). A thorough medical assessment is required before starting treatment.
