A growth disorder is a medical condition where an individual’s growth deviates significantly from the norm, either too fast or too slow, affecting height, weight, or sexual maturity. These disorders can result from hormonal imbalances (like growth hormone deficiency), genetic conditions (such as Turner syndrome or Noonan syndrome), chronic illnesses, or unknown (idiopathic) causes. Diagnosis involves physical exams, X-rays, blood tests for hormones, and other tests, while treatment varies depending on the underlying cause.
