Parameters influencing Type 1 and Type 2 diabetes mellitus

Diabetes mellitus, a long-term condition impacting millions globally, is mainly categorized into Type 1 (T1D) and Type 2 diabetes mellitus (T2D), each with distinct etiological pathways but sharing the common trait of high blood glucose levels. T1DM is marked by the autoimmune destruction of insulin-producing β-cells in the pancreas, resulting in total insulin de ciency. This condition commonly a ects younger individuals and has strong genetic and environmental determinants, including speci c genetic markers like HLA variants and exposure to certain viral infections. T2DM, conversely, is primarily inuenced by insulin resistance and a relative lack of insulin. This type typically presents in adults and is inuenced by multiple factors like obesity, sedentary lifestyle, age, and genetic predispositions. While both types of diabetes ultimately result in hyperglycemia and similar complications, their underlying mechanisms and contributing factors are notably di erent. Understanding these parameters is critical for improving diagnosis, management, and prevention strategies. This article reviews the key parameters inuencing T1DM and T2DM, focusing on genetic, autoimmune, environmental, and lifestyle factors. Through this understanding, healthcare providers and researchers can advance speci c interventions and management approaches that cater to the distinct requirements of each type of diabetes, potentially reducing the global burden of this condition.
