Is taking growth hormone pills to increase height, in the case of the pituitary gland not secreting growth hormone due to malnutrition, considered altering Allah's creation and thus Haram (forbidden) in Sharia?

The questioner's condition is pathological and must be treated, according to the hadith (definition): "Seek medical treatment, for Allah Almighty has not created a disease without also creating a cure for it." This is not considered altering Allah's creation, and therefore, there is no objection to taking pills to remove the harm.
