What is the prevalence of Congenital Hyperinsulinism?

Congenital Hyperinsulinism (CHI) is a rare condition with an estimated global incidence of approximately 1 in 25,000 to 1 in 50,000 live births. While these figures represent the best current estimates, the true prevalence of Congenital Hyperinsulinism is likely higher due to underdiagnosis and the clinical variability of the condition.

What is the estimated incidence and prevalence of Congenital Hyperinsulinism?

Congenital Hyperinsulinism is considered a rare disease. Incidence rates vary by population; for instance, in communities with high rates of consanguinity, the incidence of Congenital Hyperinsulinism can reach as high as 1 in 2,500. Because it is a condition that manifests primarily in infancy, most data focuses on birth incidence rather than total living prevalence, though improved management is increasing the number of individuals living with the diagnosis into adulthood.

Does Congenital Hyperinsulinism affect specific groups differently?

Congenital Hyperinsulinism affects both males and females equally, with no significant gender bias documented in clinical literature. Regarding age of onset, it is predominantly a pediatric condition, with the vast majority of cases presenting in the neonatal period or early infancy. However, milder forms of Congenital Hyperinsulinism may present later in childhood, often leading to diagnostic delays.

Why is gathering accurate data on Congenital Hyperinsulinism challenging?

Several factors complicate the epidemiological tracking of Congenital Hyperinsulinism:

• Underdiagnosis: Mild or transient cases of Congenital Hyperinsulinism may be mistaken for other causes of neonatal hypoglycemia.


• Genetic Complexity: With over 15 known genetic causes, the phenotypic expression of Congenital Hyperinsulinism varies widely, making uniform registry reporting difficult.


• Geographic Variability: Higher rates are observed in regions with increased rates of consanguineous marriage, which can skew global averages.

How does the DiseaseMaps community view these statistics?

While clinical data provides the broad epidemiological picture, the 5 members of the DiseaseMaps.org community living with Congenital Hyperinsulinism remind us that behind every statistic is a unique patient journey. Real-world perspectives from these community members highlight the significant impact of early detection on long-term health outcomes for those with Congenital Hyperinsulinism.
