Diabetes in Africa represents a significant and escalating public health challenge, historically overshadowed by infectious diseases such as malaria and HIV. While these diseases rightly demand attention, the rising prevalence of diabetes, particularly a newly recognized form called 'Type 5 diabetes,' requires urgent action. This article delves into the complexities of the diabetes crisis in Africa, exploring the factors contributing to its rise, the impact on affected populations, and the steps needed to address this overlooked epidemic.
The Overlooked Diabetes Crisis
For too long, the diabetes crisis in Africa has remained in the shadows, overshadowed by the urgent needs to combat infectious diseases. However, the numbers paint a clear picture: diabetes is a rapidly growing threat to the health and well-being of African populations. A detailed report in The New York Times
Understanding Type 5 Diabetes
Type 5 diabetes, also known as malnutrition-related diabetes mellitus (MRDM), was formally recognized as a distinct classification of diabetes in January 2025. This recognition, endorsed by the International Diabetes Federation (IDF) at the World Diabetes Congress 2025 in Bangkok, marks a significant step forward in addressing a long-overlooked condition. According to the International Diabetes Federation, "Type 5 diabetes represents a significant step towards addressing a long-overlooked condition and advancing health equity in diabetes care for the millions affected globally." This type of diabetes primarily affects impoverished populations in sub-Saharan Africa and South-East Asia, where chronic malnutrition is prevalent. The International Diabetes Federation notes that "The condition highlights the impact of poverty on health outcomes, particularly in communities where people face lifelong nutritional deficits." Unlike Type 1 or Type 2 diabetes, Type 5 diabetes is directly linked to prolonged periods of inadequate nutrition, leading to pancreatic damage and impaired insulin production.
Historical Neglect: Infectious Diseases Dominated
The historical focus on infectious diseases in Africa, while necessary, has inadvertently led to the neglect of non-communicable diseases like diabetes. Diseases such as malaria, HIV/AIDS, and tuberculosis have long been the primary focus of healthcare funding and public health initiatives. This prioritization has left diabetes under-resourced and under-addressed, despite its growing prevalence and significant impact on the health of African populations. The consequences of this neglect are now becoming increasingly apparent, with diabetes rates soaring and healthcare systems struggling to cope.
Current State of Diabetes in Africa
The current state of diabetes in Africa is alarming. According to the IDF Diabetes Atlas, in 2021, 24 million adults in Africa were living with diabetes. This number is projected to reach 55 million by 2045, representing a staggering 129% increase. This rapid growth is driven by a combination of factors, including urbanization, lifestyle changes, and an aging population. The WHO Regional Office for Africa reports that age-standardized incidence rates of diabetes in Africa increased from 157.284 per 100,000 population in 1990 to 250.459 per 100,000 in 2021, with Type 2 diabetes accounting for the majority of cases. Additionally, Type 1 diabetes among children and teenagers below 19 years in Africa increased five-fold between 2011 and 2021, from 4 to nearly 20 per 1,000 children [Source: WHO Africa].
Healthcare Funding Disparities
One of the most significant challenges in addressing the diabetes crisis in Africa is the severe disparity in healthcare funding. Despite bearing a substantial disease burden, Africa accounts for only 1% of global diabetes-related healthcare expenditure. The WHO Africa estimates that the annual diabetes-related expenditure in Africa is US$ 13 billion. This lack of funding severely limits the availability of essential resources, including diagnostic tools, medications, and trained healthcare professionals. The consequences of this underfunding are dire, leading to delayed diagnoses, inadequate treatment, and preventable complications.
Impact on African Populations
The impact of diabetes on African populations is far-reaching and devastating. The WHO African Region reports that premature deaths from diabetes in Africa (before age 70) account for 58% of diabetes deaths, higher than the global average of 48%. This highlights the urgent need for early detection and effective management to prevent premature mortality. Furthermore, diabetes is a leading cause of blindness, kidney failure, and lower limb amputations in Africa, placing a significant burden on individuals, families, and healthcare systems. The high rate of undiagnosed diabetes also contributes to these complications, as many people are unaware of their condition until it reaches an advanced stage.
Barriers to Diagnosis and Treatment
Several barriers hinder the diagnosis and treatment of diabetes in Africa. One of the most significant is the high proportion of undiagnosed cases. The WHO Africa Regional Factsheet indicates that 54% of people living with diabetes in Africa remain undiagnosed, the highest proportion among all IDF regions. This lack of awareness is due to a combination of factors, including limited access to healthcare services, lack of awareness about diabetes symptoms, and inadequate screening programs. Even among those who are diagnosed, access to treatment is often limited. WHO data shows that only 26.1% of adults aged 30 and above diagnosed with diabetes in Africa receive treatment, leaving over 34 million people with diabetes untreated. This treatment gap is due to factors such as the high cost of medications, lack of trained healthcare professionals, and inadequate healthcare infrastructure.
Path Forward: Policy and Prevention
Addressing the diabetes crisis in Africa requires a multi-faceted approach that includes policy changes, increased funding, and improved prevention strategies. Governments must prioritize diabetes prevention and control in their national health plans, allocating sufficient resources to support these efforts. Increased funding is needed to improve access to diagnostic tools, medications, and trained healthcare professionals. Public awareness campaigns are essential to educate people about the risk factors, symptoms, and complications of diabetes. Screening programs should be expanded to identify undiagnosed cases and ensure early intervention. Furthermore, efforts to address malnutrition, particularly in vulnerable populations, are crucial to prevent Type 5 diabetes. By working together, governments, healthcare providers, and communities can make a significant impact on the diabetes crisis in Africa and improve the health and well-being of millions of people.
In conclusion, the diabetes crisis in Africa is a complex and urgent issue that demands immediate attention. The rising prevalence of diabetes, particularly Type 5 diabetes, coupled with healthcare funding disparities and barriers to diagnosis and treatment, poses a significant threat to the health and well-being of African populations. By prioritizing diabetes prevention and control, increasing funding, and improving access to healthcare services, it is possible to mitigate the impact of this silent epidemic and create a healthier future for Africa.
