Hypopituitarism

Hypopituitarism is a group of disorders that can affect children and adults. It refers to a series of syndromes caused by partial or complete damage to the pituitary gland due to various reasons, such as pituitary tumors, infections, hemorrhage, or trauma (including surgery), resulting in insufficient secretion of one or more hormones, including growth hormone, gonadotropins, adrenocorticotropic hormone, thyroid-stimulating hormone, prolactin, or antidiuretic hormone. According to the affected site, hypopituitarism can be divided into: Anterior Pituitary Hypofunction: This condition refers to a decrease in one, multiple, or all hormones secreted by the pituitary gland, such as growth hormone, gonadotropins, adrenocorticotropic hormone, thyroid-stimulating hormone, and prolactin, due to tumors, infections, or trauma. This subsequently leads to hypofunction of corresponding target organs, such as the thyroid gland, gonads, and adrenal glands. The manifestations of this condition are variable and non-specific, making it easily overlooked. Central Diabetes Insipidus: This condition refers to a disease caused by genetic factors, tumors, infections, or trauma, resulting in damage to the hypothalamus, pituitary stalk, or posterior pituitary, leading to impaired synthesis, transport, or secretion of antidiuretic hormone. This causes patients to experience a significant increase in urine output (often exceeding 2500 mL/24h).
