What is the Origin of Type 1 Diabetes?

The understanding of diabetes dates back to antiquity, but the distinction of Type 1 as an insulin-dependent form emerged with the discovery of insulin in the early 20th century. Later research confirmed the autoimmune etiology, where the body's own immune system mistakenly attacks the beta cells. The 'Type 1' designation differentiates it from the more prevalent insulin-resistant Type 2 form.

What is the Mechanism of Type 1 Diabetes?

The pathological mechanism involves a cellular autoimmune response, often triggered by genetic predisposition and environmental factors, where T-lymphocytes infiltrate the pancreatic islets. This insulitis leads to the progressive and irreversible destruction of the beta cells. Without sufficient beta cells, the pancreas cannot secrete enough insulin to facilitate glucose uptake by peripheral tissues, resulting in hyperglycemia and the metabolic shift toward lipolysis and ketone body production.

Type 1 Diabetes

Meaning

Type 1 Diabetes (T1D) is a chronic autoimmune endocrine disorder characterized by the absolute deficiency of insulin production resulting from the immune-mediated destruction of the insulin-producing beta cells in the pancreatic islets of Langerhans. This lack of insulin necessitates lifelong exogenous insulin replacement therapy to regulate blood glucose levels and prevent acute metabolic complications. It is a critical condition requiring rigorous glycemic management and patient education.
