Diabetes Mellitus is classified into several categories based on its cause, pathophysiology, and onset. Here’s an overview:
1. Major Types of Diabetes
Type 1 Diabetes – Autoimmune destruction of pancreatic beta cells, leading to absolute insulin deficiency.
Type 2 Diabetes – Characterized by insulin resistance and progressive beta-cell dysfunction.
Gestational Diabetes Mellitus (GDM) – Diabetes diagnosed during pregnancy, which may resolve postpartum or persist.
Monogenic Diabetes – Includes Maturity-Onset Diabetes of the Young (MODY) and Neonatal Diabetes, caused by single-gene mutations.
2. Diabetes Due to Other Causes
Pancreatic Diseases – Conditions like chronic pancreatitis, cystic fibrosis, or pancreatic cancer can impair insulin production.
Endocrine Disorders – Cushing’s syndrome, acromegaly, and pheochromocytoma can lead to diabetes.
Drug-Induced Diabetes – Caused by medications like glucocorticoids, antipsychotics, and immunosuppressants.
