Endocrinology within propedeutics of internal diseases is the science of the body's delicate regulatory mechanisms. In this section, we study how subtle, macroscopically invisible impairments in the endocrine glands and hormonal regulation manifest in the patient's appearance, complaints, and metabolism.
The material covers basic algorithms for patient interviews and physical examination, as well as the interpretation of key laboratory and instrumental findings. You will study the developmental mechanisms and clinical presentation of major endocrine pathologies: thyroid disorders (Graves' disease, hypothyroidism), adrenal cortex disorders (hypercorticism, chronic insufficiency), and parathyroid glands.
During practical classes and exams, instructors traditionally demand a thorough understanding of diabetes mellitus. We will break down its etiology, pathogenesis, clinical features, and treatment in detail. Pay special attention to emergency conditions: the ability to differentiate acute diabetic complications (comas) is a core skill required of a physician of any specialty to save a patient's life.
This is the principle of system self-regulation. When a peripheral gland secretes a large amount of hormone, it suppresses the activity of higher-level structures (the hypothalamus and pituitary gland) to halt further stimulation.
Why are changes in the heart, GI tract, and other organs evaluated when endocrine pathology is suspected?
Hormones have systemic effects and influence all body tissues. Diagnosis is always based on comparing laboratory data (hormonal profile) with diverse clinical manifestations involving the skin, heart, gastrointestinal tract, and nervous system.
Why is radiography rarely used?
Among all imaging modalities, radiography has the lowest diagnostic value for assessing the structure of endocrine glands. It has been replaced by ultrasound, CT, and MRI.
Can tumors be the cause of both hyperfunction and hypofunction of a gland?
Yes. A tumor may consist of hormonally active cells leading to hyperfunction, or conversely, it may destroy and replace normal functional glandular tissue, causing hypofunction.
Why do patients with thyrotoxicosis lose weight despite having a good appetite?
Thyroid hormone excess drastically accelerates all types of metabolism. Energy is consumed so rapidly that even increased food intake fails to compensate for weight loss.
Why does hypothyroidism cause voice coarsening and hearing loss?
This occurs due to specific myxedematous edema—the accumulation of mucopolysaccharides in the tissues of the vocal cords and the mucous membrane of the Eustachian tube.
