Girls usually begin to grow around the time that they hit puberty. When it does come, you might get a spurt where you grow quickly or slowly. Most girls reach their full height around the age of 14 years old to 15 years old, when puberty ends (which is around the ages of 8 years old and 13 years old, commonly 11 years old).
It could possibly be a stroke.
