This course offers a comprehensive understanding of endocrine physiology, hormonal regulation, and the diagnosis and management of disorders affecting endocrine glands. It integrates basic science, clinical medicine, and diagnostic endocrinology, emphasizing the correlation between hormonal imbalances and systemic manifestations.
Students will gain exposure to the full range of endocrine conditions, including pituitary, thyroid, parathyroid, adrenal, pancreatic, and gonadal diseases, as well as metabolic and nutritional disorders. The course combines bedside clinical teaching, case discussions, and laboratory interpretation, preparing students to recognize and manage both chronic endocrine diseases and acute endocrine emergencies.
Practical experience will focus on clinical examination of endocrine systems, interpretation of hormonal assays, and management strategies for diabetes mellitus, thyroid disorders, adrenal dysfunction, and metabolic syndromes.
Course Objectives:
By the end of the course, students should be able to:
- Describe the anatomy, physiology, and pathophysiology of endocrine glands.
- Perform a systematic endocrine examination and obtain a detailed hormonal history.
- Interpret laboratory and imaging investigations related to hormonal and metabolic disorders.
- Diagnose and manage endocrine disorders including thyroid, pituitary, adrenal, pancreatic, and gonadal diseases.
- Identify and treat endocrine emergencies such as thyroid storm, myxedema coma, adrenal crisis, and diabetic ketoacidosis.
- Understand and apply preventive strategies for metabolic and endocrine diseases.
- Demonstrate ethical and professional communication with patients and multidisciplinary teams.
