Pituitary adenomas are benign tumors that grow in the pituitary gland, causing it to produce too much or too little of certain hormones.

Growth hormone is produced by the pituitary gland and is responsible for regulating growth and development in children and adolescents.

Acromegaly is a condition caused by an overproduction of growth hormone in adults, leading to abnormal growth of the bones and soft tissues.

Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland and is responsible for regulating the production of cortisol by the adrenal glands.

Cushing's disease is a condition caused by an overproduction of cortisol by the adrenal glands, which is often due to an overproduction of ACTH by the pituitary gland.

Prolactin is produced by the pituitary gland and is responsible for regulating the production of milk in women who are breastfeeding.

Prolactinoma is a condition caused by an overproduction of prolactin by the pituitary gland, which can lead to infertility, menstrual irregularities, and galactorrhea (production of milk in women who are not breastfeeding).

Thyroid-stimulating hormone (TSH) is produced by the pituitary gland and is responsible for regulating the production of thyroid hormones by the thyroid gland.

Hypothyroidism is a condition caused by an underproduction of thyroid hormones, which can lead to fatigue, weight gain, constipation, and depression.

Vasopressin is produced by the hypothalamus and is responsible for regulating the production of antidiuretic hormone (ADH) by the pituitary gland.

Diabetes insipidus is a condition caused by an underproduction of antidiuretic hormone (ADH), which can lead to excessive thirst and urination.

Oxytocin is produced by the hypothalamus and is responsible for regulating the production of oxytocin by the pituitary gland.

Syndrome of inappropriate antidiuretic hormone (SIADH) is a condition caused by an overproduction of oxytocin, which can lead to hyponatremia (low sodium levels in the blood).

Gonadotropin-releasing hormone (GnRH) is produced by the hypothalamus and is responsible for regulating the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) by the pituitary gland.

Hypogonadism is a condition caused by an underproduction of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which can lead to infertility, menstrual irregularities, and decreased libido.
