Fröhlich’s syndrome
a disorder caused by underfunctioning of the anterior lobe of the pituitary gland (hypopituitarism), often because of tumors on the hypothalamus. Major symptoms are underdeveloped genital organs and secondary sexual characteristics, general sluggishness, and obesity; in some cases, those with Fröhlich’s syndrome exhibit polyuria (frequent urination), polydipsia (frequent consumption of liquids), and intellectual disabilities. Also called Launois–le Cleret syndrome. [Alfred Fröhlich (1871–1953), Austrian neurologist]
