In Reunion Island, diabetes prevalence has reached 13%, double the rate observed in mainland France, affecting nearly 90,000 residents.
Ahead of World Diabetes Day on November 14, local health authorities are intensifying screening efforts to address this chronic condition, which continues to affect regional public health.
- Asymptomatic Progression: Type 2 diabetes often develops without noticeable symptoms, making routine blood glucose screening the primary method for early detection.
- Gestational Risks: One in five pregnant women on the island is affected by gestational diabetes, a frequency that has increased significantly over the last decade.
- Complication Prevention: Regular monitoring of blood sugar levels is vital to prevent long-term damage to the kidneys, heart, and feet.
Data presented by the Agence Régionale de Santé (ARS) highlights that Reunion is the most affected French region. The impact is disproportionately felt by the elderly and women. Beyond the raw prevalence, the clinical reality involves severe health outcomes; in 2024, 3,400 patients were hospitalized for complications involving cardiovascular, renal, or podiatric systems.
The clinical mechanism of type 2 diabetes involves insulin resistance, where cells fail to respond effectively to insulin, leading to chronic hyperglycemia (high blood sugar). If left unmanaged, this state damages vascular structures, leading to the complications observed in the island’s hospital data.
Public health officials emphasize that while biological monitoring is improving, the utilization of specialized care—specifically ophthalmological and cardiological services—remains insufficient to meet the needs of the population.
Despite the high prevalence, there is a positive trend in early detection. Approximately 76% of individuals with type 2 diabetes on the island were diagnosed through systematic screening, compared to 68% in mainland France.
Access to a balanced diet and regular physical activity is not solely a matter of individual agency; it is deeply tied to socioeconomic stability. As the ARS notes, the challenge lies in bridging the gap between clinical recommendations and the daily reality of those living in precarious conditions, where healthy choices may be financially or logistically inaccessible.
| Indicator | Reunion Island | Mainland France |
|---|---|---|
| Diagnosis via Screening | 76% | 68% |
| Diagnosis via Complication | 8% | 11% |
Individuals with a family history of diabetes or those identified as high-risk by the "FindRisk Péi" questionnaire available on Masanté.re should consult their primary care physician for a blood glucose panel.
There is no "contraindication" to screening; however, patients should be wary of unverified nutritional advice or "miracle cures" circulating on social media. Evidence-based management relies on the clinical consensus provided by endocrinologists and dietitians.
To combat the rising numbers, the ARS has scheduled several public health villages around the November 14 awareness date. These sessions provide on-site screening, dietary counseling, and clinical guidance. Events are planned for November 13 at the Plateau Noir du Guillaume (Saint-Paul), November 14 at the Halle François-Mitterrand (Saint-Joseph), and November 15 at the Barachois (Saint-Denis).
While screening rates are improving, the persistent rate of gestational diabetes and the high volume of hospitalizations for chronic complications remain open questions for public health policy.
