Tall Stature
Background
Definitions
Tall stature refers to a height more than 2 standard deviations above the mean for age, sex, and population. Statistically, this is defined as the 2.3rd percentile.
While short stature is a common presenting concern, few children or parents seek medical attention, presumably because it is socially acceptable and/or may be seen as advantageous.

Causes of tall stature include:
Physiologic/normal variants
- Constitutional advancement of growth
- Familial tall stature
Endocrine disorders

- Obesity
- Pituitary gigantism (excess growth hormone)
- Precocious puberty (growth spurt)
Genetic disorders
