Why Diabetes and Thyroid Dysfunktion Commonly Coexitt
Diabetes and thyroid disorders share a bidirectional contraship that goes far beyond coincitence. Epidemiological studies indicate that people with diabetes - particarly those with type 1 diabetes - have a prevalence of thyroid dysfunktion that is two to three times higher than thee generaon. inter type 1 diastetics, ratetics of autoimnate thyroid disease excead 30% in some cohort, while type 2 diacetics facetated risks n by metatros.
