High Blood Sugar (Hyperglycemia) - Diabetes Mellitus - Endocrinology

Learn about hyperglycemia and its relationship to diabetes mellitus in this comprehensive 18-minute endocrinology video. Explore the pathophysiology of high blood sugar, including the roles of key hormones such as insulin, glucagon, somatostatin, cortisol, epinephrine, and thyroid hormones (T3, T4) in glucose regulation. Understand the anatomy and function of the pancreas and Islets of Langerhans in maintaining glucose homeostasis. Examine the classic symptoms of hyperglycemia including polydipsia (excessive thirst), polyphagia (excessive hunger), polyuria (frequent urination), weight changes, delayed wound healing, blurry vision, headaches, and skin manifestations like xeroderma and itching. Discover the metabolic processes involved in glucose regulation, including glycogenolysis, gluconeogenesis, glycolysis, and glycogenesis during feeding and fasting states. Study the different types of diabetes mellitus, including type 1, type 2, and gestational diabetes, along with their underlying mechanisms. Learn about the impact of macronutrients (carbohydrates, fats, proteins) on blood glucose levels and explore various causes of hyperglycemia such as glucocorticoids, corticosteroids, paraneoplastic syndromes, endocrine tumors, infections, and stress. Gain insights into diagnostic markers like C-peptide and understand rare conditions such as insulinoma and glucagonoma that can affect glucose metabolism.
