What are the common diseases of the endocrine system?

Common diseases in the Department of Endocrinology mainly include the following categories: 1. **Diabetes mellitus**: The most common endocrine system disorder, primarily characterized by insufficient insulin secretion or reduced cellular response to insulin, leading to elevated blood glucose levels. Diabetes can cause various complications and significantly affect patients' quality of life. 2. **Thyroid diseases**: Such as hyperthyroidism and hypothyroidism, which result from abnormal secretion of thyroid hormones. These conditions manifest as accelerated or slowed metabolism, along with a series of related symptoms. 3. **Adrenal gland diseases**: Such as Cushing's syndrome and primary aldosteronism, which are typically caused by dysfunction of the adrenal cortex or medulla, leading to hormonal imbalances and a range of associated symptoms. Patients experiencing related symptoms should seek medical attention promptly, allowing physicians to make accurate diagnoses and develop appropriate treatment plans based on individual conditions.
