What percentage of diabetes cases does type 2 diabetes mellitus typically account for?

Type 2 diabetes mellitus typically accounts for approximately 90% of all diabetes cases. This condition is characterized by insulin resistance and relative insulin deficiency, making it more common than type 1 diabetes, which is an autoimmune condition and accounts for a much smaller percentage of cases. The high prevalence of type 2 diabetes is often linked to various factors including obesity, physical inactivity, and genetic predisposition. Understanding this statistic highlights the importance of addressing lifestyle factors in the prevention and management of diabetes, as well as the need for healthcare providers to focus on education and support for those at risk for this prevalent condition.
