Hypopituitarism is a condition in which the pituitary gland in the brain is not working properly. The pituitary gland, located within the sella turcica at the base of the brain is the master regulator of growth, puberty, metabolism, response to stress, reproduction and lactation (54). It makes hormones that affect how other glands in the body make hormones. Cause. Causes of hypopituitarism. Pituitary adenomas are almost invariably benign (not cancerous). Any condition that damages the pituitary gland or the area of the brain known as the hypothalamus (which regulates the pituitary gland's function) can cause the pituitary to decrease hormone production. As a pituitary tumor increases in size, it can compress and damage pituitary tissue, interfering with hormone production. In some cases, healthcare providers can't determine the cause.

There are numerous causes of hypopituitarism (see Table 1). The pituitary gland produces hormones that regulate some of your body's major functions. If there is decreased secretion of one specific pituitary hormone, the condition is known as selective hypopituitarism. In this article, we explain hypo- and hyperpituitarism, which are disorders resulting from improper pituitary gland function. We also cover the procedure called hypophysectomy, which is the removal of the pituitary gland. The pituitary gland has two parts, the anterior pituitary and the posterior pituitary, and hormone production can be affected in either or both parts. Symptoms of hypopituitarism depend on what hormone is deficient and may include short height, infertility, intolerance to cold, fatigue, and an inability to produce breast milk. Cystic tumors. In general, these three main factors can cause hypopituitarism: Something is putting pressure on (compressing) your pituitary gland or hypothalamus.
