Can i grow taller at age 18? im a female 5 flat tall and would want to grow just a couple inches

Doubt it: Linear growth depends on having open growth centers. An x-ray of the wrist/hand is a common site to look for these since so many are available to see. When these centers are closed on x-ray, you are inished. The hormones that signal the transition into puberty accelerate the closure of growth centers. Most stop 3 inches after their first menses.This is usually by 17-18.
