Diabetes Diagnosis and Management in 2025: What’s New for South Africans?

Last year, SAMDP published the widely read blog “Understanding Diabetes: Your Questions Answered,” which unpacked the basics of diabetes, from causes and symptoms to prevention and daily management. The response was overwhelmingly positive, with many readers asking: What’s next? What’s changing in diabetes care?

This year, as we mark World Diabetes Day 2025 on 14 November, we pick up exactly where we left off. The conversation has evolved, and so has the science. New therapies, devices, and digital tools are reshaping how diabetes is diagnosed and managed. Yet, as innovation accelerates, the biggest challenge remains ensuring access for all.

According to the International Diabetes Federation (IDF), over 4.3 million South Africans live with diabetes, and nearly half remain undiagnosed. South Africa now stands at a critical point: we have the potential to lead the continent in modern diabetes care, but only if innovation translates into inclusion.

For 2025, the International Diabetes Federation (IDF) emphasises ‘Diabetes and Well-being’ with a focus on workplace inclusion, while the World Health Organization (WHO) highlights diabetes care across all life stages. Together, these themes remind us to nurture health in every environment and age, beyond just treatment.

What’s new since last year?

1. Updated Standards of Care

The 2025 Standards of Care in Diabetes bring new guidance for diagnosis, treatment, and long-term management.

Key updates include:

Earlier and more frequent screening: Adults aged 35+ should be screened every three years; high-risk groups (those with obesity, hypertension, or family history) annually.
Personalised targets: Aim for HbA1c <7% for most adults, adjusted for individual needs.
Early combination therapy: For patients with HbA1c >9%, starting two medications upfront is now recommended.
Holistic management: Emphasis on cardiovascular, kidney, and mental health alongside glucose control.

Why this matters: Following evidence-based guidelines helps reduce blindness, kidney failure, amputations, and premature death, complications still far too common in South Africa.

2. Emerging Technologies Revolutionising Care

2.1. Continuous Glucose Monitoring (CGM)

Wearable sensors track glucose levels in real time, helping patients understand how food, stress, and activity affect their bodies.

Benefit: Better control and fewer emergencies.
Challenge: Cost — still out of reach for most South Africans.

2.2. Smart Insulin Pens & Automated Delivery Systems

Devices now track doses, sync with mobile apps, and can even adjust insulin delivery automatically, mimicking a healthy pancreas.

2.3. Digital Health & Telemedicine

From WhatsApp-based check-ins to virtual consultations, digital platforms are improving follow-up and adherence, especially in rural areas.

Reality check: South Africa faces an innovation divide, where one patient uses a CGM linked to an app, another tracks blood sugar with pen and paper. The challenge is not technology, but equitable access.

3. New Therapeutics shaping the future

3.1. GLP-1 Receptor Agonists and SGLT2 Inhibitors

These newer classes of medicines not only lower glucose but also protect the heart and kidneys while promoting weight loss.

Impact: Fewer heart attacks, less kidney disease, and better quality of life.
Access: Available in private care, but limited in the public sector.

3.2. Once-Weekly Insulin

A game-changer in patient convenience — making adherence easier for those who struggle with daily injections.

3.3. Combination Therapies

Simplified “two-in-one” injections reduce treatment fatigue and improve outcomes.

4. Regenerative Research on the Horizon

Researchers are exploring stem-cell–based beta-cell regeneration and immune-modulating therapies that could one day restore the body’s natural insulin production — signalling hope for long-term remission, particularly in Type 1 diabetes.

Bridging the Innovation Divide in South Africa

The Health-e News report “Bridging the Innovation Divide: Making Modern Diabetes Care Accessible to All” (2025) highlights a sobering truth: while breakthroughs in diabetes care multiply, millions of South Africans are being left behind. “Innovation has given us extraordinary tools,” the article notes, “but the true measure of progress is ensuring that these tools are accessible to everyone.”

The Equity Gap

Urban, privately insured patients often benefit from advanced therapies and devices.
Rural and lower-income patients face medication shortages and limited diagnostic tools.
Women and working-class communities bear a disproportionate burden of care.

Bridging Efforts

Public-private partnerships are expanding pilot access to CGM devices in some provincial hospitals.
Education drives are equipping nurses and community health workers to screen and counsel earlier.
The 2025 Diabetes Summit will be held from 11 to 13 November 2025 at the Radisson Hotel & Convention Centre, Johannesburg, O.R. Tambo Airport, Gauteng, South Africa. Organised by the Diabetes Alliance, this national multi-stakeholder conference unites healthcare professionals, people living with diabetes, policymakers, academics, civil society, and private sector leaders to discuss innovations in diabetes prevention, education, care, and research. It is CPD-accredited and aligns with national health priorities, aiming to drive collaborative action across sectors.

What Healthcare Practitioners can do

Stay informed: Follow updates on new therapies and devices.
Screen opportunistically: Every visit is a chance to detect early.
Advocate: Push for inclusion of newer drugs and devices in national and medical-aid formularies.
Educate: Empower patients with knowledge — understanding drives adherence.
Collaborate: Multidisciplinary teamwork improves outcomes and patient support.

For patients and families

Know your risk: Get tested if you’re 35 or older, overweight, or have a family history of diabetes.
Make sustainable changes: Focus on small, daily habits — balanced meals, movement, rest.
Stay consistent: Follow-ups prevent complications.
Ask questions: Learn about all your treatment options.
Seek support: Join diabetes education or peer groups for motivation.

Building a more equitable future

As we look to the future, one truth stands firm , science alone doesn’t save lives; access does. Innovation must be matched with inclusion so that every person living with diabetes in South Africa , whether in a township clinic or a private facility has the same chance at health, hope, and longevity.

This World Diabetes Day, guided by the dual imperatives of well-being at work and lifelong care, SAMDP commits to championing an inclusive diabetes future for South Africa , one where innovation meets accessibility, and every person can thrive, regardless of age or occupation.

By building on last year’s foundation, SAMDP continues its mission to empower healthcare practitioners and the public with credible, practical, and forward-thinking health information. This World Diabetes Day 2025, let’s work together to close the gap, to make modern diabetes care accessible, affordable, and equitable for all.
