Wearables For Chronic Disease Management In Low-Resource African Settings: Promise Meets Practical Limits

A blood pressure cuff and a paper chart have managed hypertension in Nigerian clinics for decades. That basic setup is now being layered with something newer: wristbands, patches, and rings that log heart rate, glucose trends, and activity continuously, without a patient having to remember to write anything down. The question facing African health systems is not whether this technology works, but whether it can survive contact with clinics that sometimes run out of the medicines it is meant to support.

Non-communicable diseases have become one of the defining health burdens on the continent. In Nigeria’s Federal Capital Territory, a study of primary healthcare centres found hypertension affecting an estimated 25 to 40 percent of adults, yet fewer than one in five hypertensive patients were on treatment, and only about 9 percent had their blood pressure under control. The same study found that 59 percent of the facilities surveyed had zero blood pressure medication in stock at the time of assessment. That gap between diagnosis and effective treatment is the backdrop against which every wearable pilot on the continent must be judged.

What Wearables Are Actually Being Tested For

Most of the clinical interest in Africa centres on two conditions: diabetes and hypertension, both of which require frequent, low-cost monitoring rather than occasional hospital tests. A 2025 review in Chronic Diseases and Translational Medicine looked at continuous glucose monitors and fitness trackers across several low- and middle-income countries, including case studies from Ghana and Ethiopia, and found that wearables could meaningfully improve glycaemic control and patient engagement — but that cost, digital illiteracy, and poor integration with existing health records remained persistent obstacles. None of those obstacles are…
