Idiopathic short stature (ISS) refers to extreme short stature that does not have a diagnostic explanation (idiopathic designates a condition that is unexplained or not understood) after an ordinary growth evaluation. The term has been in use since at least 1975[1]
without a precise percentile or statistical definition of "extreme".

Diagnosis

Definition

In 2003

growth hormone for the treatment of ISS.[2] They proposed a definition of a height more than 2.25 standard deviations below mean, roughly equal to the shortest 1.2% of the population. [3]

Other researchers have described a cutoff of 2.0 standard deviations.[4]

Treatment

There is some evidence that hormone treatment may not result in a significant improvement in psychosocial functioning.[5]

It is estimated that it would cost US$100,000 or more [6] to treat someone, but might only move them from the first percentile to perhaps the 10th. There is some ethical and economic concern whether such treatment would merely shift discrimination to the next most effected percentile.[

aromatase inhibitors[8]
have been proposed as an alternative to growth hormone.

Advantage

Short stature decreases risk of venous insufficiency.[9]
