Pathophysiology
Clinical meaning
Endocrine disorders arise from dysregulation of hormone secretion, often due to glandular dysfunction, autoimmune processes, or neoplasia. At the cellular level, alterations in receptor sensitivity, hormone production, or feedback mechanisms lead to either hypersecretion or hyposecretion of hormones. For example, in Type 1 Diabetes Mellitus, autoimmune destruction of pancreatic beta cells results in insufficient insulin production, leading to hyperglycemia. Conversely, conditions like Cushing's syndrome involve excessive cortisol production due to adrenal hyperplasia or pituitary adenomas. The pathophysiological changes manifest in various tissues, impacting metabolism, growth, and homeostasis. Chronic hormone imbalances can lead to systemic complications, including cardiovascular, renal, and neurological alterations, emphasizing the importance of early detection and management.
