When the number of cells becomes too low, an organ cannot function normally. Thus, most organs function less well as people age
In hypopituitarism, there is a lack of one or more pituitary hormones. Lack of a hormone leads to loss of function in the gland or organ the hormone controls. For example, lack of TSH leads to loss of normal function of the thyroid gland. Hypopituitarism may be caused by: Brain surgery. Brain tumor
