Symptoms of Congenital Adrenal Hyperplasia
Girls will most often have normal female reproductive organs. However, they can experience abnormal menstrual periods, ambiguous genitalia that often appears more male than female, deep voice, failure to menstruate, early appearance of armpit hair and pubic hair, and facial hair and excessive hair growth.
Boys will seem fine at birth and won't have any obvious symptoms. However, boys may seem to enter puberty much earlier than normal, such as at two to three years old. They may also experience deep voice, well-developed muscles, early appearance of armpit hair and pubic hair, small testes, developing male characteristics early, and enlarged penis.
Some forms of this genetic disorder are more severe than others and cause adrenal crisis in newborns due to salt loss. When newborns have the more severe forms, they develop symptoms that are severe shortly after they are born. These include cardiac arrhythmias, electrolyte changes, dehydration, and vomiting.
