Question: Delayed Puberty

 SheltieSweetie - Fri Oct 13, 2006 8:57 pm

My daughter is 16 years old, fully developed....but she's never had a period. Is this normal? She's obese, if that helps any. I'm just starting to worry. Thanks.

User avatar There are several criteria for how to determine when a girl is delayed in starting her menses. Menarche (the first episode of the menstraul cycle) is considered delayed if girls have not started by age 16 or within 2 years of beginning breast development. The best indicator of when a girl will start having periods is the age at which her mom had her first period. If mom was older, it is likely the girl will be older as well.

Delayed menarche can be associated with several factors. Obesity may or may not be related. Obesity can be seen in a syndrome called polycystic ovarian syndrome that can have delayed and irregular menstrual cycles.

I would recommend that she be evaluated by a physician to determine the cause of her delay.

Hope that helps.

Thank you for replying!

Her breasts have been developing since she was 11, or 12. I recieved my first period at 11. We've wondered about polycystic ovarian syndrome, but the doctor keeps telling us it's just because she's obese.

User avatar Having not had a period yet would be considered primary amenorrhea for her in that she is sixteen and it has been over two years since breast development.

You may consider requesting an adolescent medicine consultation, or an OB/Gyn consultation if adolescent medicine specialists are not available.

There are treatments for polycystic ovarian syndrome (PCOS), but there are also other causes of amenorrhea that should be evaluated to make sure that it is not one of these.

Hope this helps.
