Hi Marg,
The fact that you’ve haven’t grown
in the past couple of years is completely normal.
Girls generally experience a final growth spurt, which peaks at
about age
12, slows rapidly to about age 14 or 15, then tapers off until about age
18,
when growth is usually complete.
This
growth spurt generally occurs later in boys, where it peaks at age 14 or
15 and
is not complete until about age 21.
The average growth rate for a 17
year-old female is around 0.5 cm (about 3/16 of an inch) per year, as
opposed to
about 9 cm (3.5 ins.) per year for a 12 year-old.
So even if your parents were not short, there would probably not be
much
chance for a significant increase in your height at this stage of your
growth.
Although short parents can have much taller offspring, the fact
that both
are short is probably also a good indicator that you won’t grow very much
taller.
I don’t think that there is much
that
can be done to increase your height at this stage.
Growth hormone can be used to treat young children with extremely
short
stature, but I’m not sure that it would be available or have much of an
effect
on a 17 year-old (see report on "Growth
Hormone in Children" from the NHS Executive South West Research &
Development
Directorate; Bristol, UK).
Thanks for the interesting question,
Jeff
