Is it too late to see a pediatric endocrinologist in january if ihaven't hit puberty and i'm 16? what can the effects be if idon't see a doctor?

Should consult: In majority on set of puberty by 12 to 13 year in girls, and 14 for boys, cgd constitutional growth delay due to variety of causes , your parents also must be concerned , first to see your pediatrician.

Not specificly: You get in when they have time to see you. The problems you face have been ongoing for years & any rx would likely run years too. Your pcp may be able to order some basic testing that the endo could use before you go & could get a list by calling the endo's office.

Not too late: It's definitely not too late and would probably be a good idea if there are no signs of pubertal development at all. Your pediatrician or family doctor would be a good place to start.
