Endocrinological conditions involve disorders of the endocrine system, which regulates hormones crucial for various bodily functions. These conditions range from thyroid disorders like hypothyroidism and hyperthyroidism to adrenal gland disorders such as Cushing's syndrome and Addison's disease, as well as diabetes mellitus and polycystic ovary syndrome (PCOS). Research into endocrinological conditions aims to improve understanding of hormonal imbalances, develop better treatments, and enhance quality of life for those affected.
