Both Type 1 and Type 2 diabetes exhibit extensive comorbidity with other metabolic, endocrine, and cardiovascular disorders, supported by large-scale epidemiological and genetic studies.
The retrieved literature consistently confirms that both Type 1 and Type 2 diabetes frequently co-occur with other metabolic conditions, cardiovascular-kidney-metabolic syndromes, and endocrine dysfunctions. Multiple large-scale studies and umbrella reviews support this claim, and there are no papers refuting it.
