In an exclusive interview with IGIHE, Dr. Berhane Redae, a consultant endoscopic surgeon at KFHR, revealed that the procedure was introduced locally to save patients the cost and inconvenience of seeking the service abroad.
'Gastric balloon placement is a well-established global procedure. For years, patients had to travel to Kenya, Turkey, or elsewhere just to get it done. Now, everything is available here in Rwanda,' said Dr. Redae.
The procedure involves placing a silicone balloon inside the stomach using an endoscope. Once inserted, the balloon is filled with sterile water, occupying space in the stomach and helping patients feel full faster. The result is reduced food intake, smaller portions, and steady weight loss over several months.
According to Dr. Redae, the entire process, from preparation to recovery, takes less than an hour. The balloon itself is inserted in 15 to 20 minutes under light sedation, and the patient can return home the same day.
'We use anaesthesia and so the patient sleeps and feels no pain or discomfort,' he explained. 'It's far less invasive than surgery and completely reversible.'
The gastric balloon remains in the stomach for about six months. During this period, patients are encouraged to adopt healthier habits, particularly around portion control, physical activity, and nutrition.
'The gastric balloon is reversible,' Dr. Redae explained. 'If the patient doesn't follow the recommended lifestyle changes, they can regain the weight, just like with surgery. The idea is that during the six months it's in place, the patient adapts to a new lifestyle. If they maintain that lifestyle, the weight loss is sustainable.'
Who is it for?
The ideal candidates for this procedure are adults with a Body Mass Index (BMI) between 27 and 40, typically individuals classified as overweight or moderately obese. For those with a BMI above 50, Dr. Redae says additional interventions such as surgery may be more suitable.
The expected average weight loss is about 15% of a patient's starting weight, though outcomes vary depending on personal discipline, diet, and activity levels. 'For someone who weighs 100 kg, they might lose around 15 kg within the balloon's placement period,' said Dr. Redae.
Safety and aftercare
Dr. Redae reassures patients that the procedure is among the safest weight loss interventions available.
'It doesn't permanently alter the body. If necessary, we can remove the balloon early without complications.'
Complications, though rare, may include nausea, discomfort, or, in very rare cases, balloon leakage (deflation). Patients are educated on warning signs and have access to follow-up care throughout the six-month period.
'It's a very well-proven silicone product. It won't burst easily,' Dr. Redae said. 'But if there's a manufacturing defect and water leaks, it can result in dyspepsia or other self-destruction signs, which may happen.'
King Faisal Hospital offers scheduled follow-up appointments at one week, one month, three months, and six months to monitor patient progress, provide nutritional counselling, and support long-term success.
Cost
At present, the gastric balloon itself must be purchased out-of-pocket from pharmacies, though the endoscopic procedure is covered by medical insurance. Dr. Redae believes that, in time, insurers will begin recognising the value of obesity treatment.
'Obesity is not just a cosmetic issue, it's a disease,' he said. 'By helping people lose weight, we reduce the risk of diabetes, hypertension, cardiovascular disease, and joint problems. It's preventive medicine.'
With rising urbanisation, sedentary lifestyles, and changing dietary habits, obesity is becoming an increasingly pressing health issue in Rwanda, much like in many parts of the world. Dr. Redae believes the gastric balloon is a crucial tool in addressing this challenge.
'This is just one tool,' Dr. Redae said. 'But it's a valuable one, especially for people who've struggled with other weight loss options.'
For those considering the procedure, Dr. Redae's advice is for them to start with a consultation.
'Come in, talk to a physician, and we'll work with you to find the best path forward.'
