If your daughter has not started puberty, is not developing breasts by age 13, or has no period yet, get clear next-step guidance based on her age, growth, and development.
Share whether there is no breast development yet, no period yet, slow growth, or puberty that seems to have stalled, and get a personalized assessment for delayed puberty in girls.
Delayed puberty in girls usually means breast development has not started by age 13, or periods have not started several years after puberty begins. Some girls simply develop later than peers, but certain patterns can be worth a closer look, especially if growth seems slow, puberty started very late, or development has stopped progressing. This page is designed to help parents understand common signs of delayed puberty in girls and when to worry.
A girl not developing breasts by age 13 is one of the most common reasons families ask about late puberty in girls.
If breast development started years ago but there is still no period yet, delayed puberty may need medical review depending on timing and other symptoms.
Parents may notice that height is not changing as expected, or that puberty began but has not continued in a typical way.
Some girls are healthy late bloomers, especially if a parent also had later puberty.
Low body weight, poor nutrition, chronic illness, or very high athletic training can affect hormone signals and delay puberty.
In some cases, delayed puberty in girls is linked to hormone differences, ovarian conditions, or other health issues that should be evaluated by a doctor.
If your daughter has not started puberty at all by age 13, it is reasonable to speak with her pediatrician.
If breast development began but periods still have not started after a long gap, a medical visit can help clarify what is normal and what is not.
Poor growth, weight changes, fatigue, headaches, or other symptoms along with late puberty deserve prompt attention.
Many families start with a pediatrician, who can review growth charts, timing of development, family history, nutrition, and overall health. If needed, your child may be referred to a pediatric endocrinologist, a doctor for delayed puberty in girls who specializes in hormones and growth. Getting guidance early can help you understand whether your daughter is simply developing later or needs further evaluation.
A common definition is no breast development by age 13, or no menstrual period after puberty has been underway for several years. Timing can vary, so age, growth pattern, and overall health all matter.
Not always. Some girls naturally start later, especially if there is a family history of late puberty. But if there are no signs of breast development by age 13, it is a good idea to check in with her doctor.
No. Periods usually begin after breast development has already started. If puberty began recently, waiting may be normal. If a long time has passed since breast development started and there is still no period, medical guidance is appropriate.
Causes can include a normal family pattern of later development, low body weight, chronic illness, high athletic activity, nutritional issues, or hormone-related conditions. A doctor can help sort out which explanation fits best.
Start with your pediatrician. If more specialized evaluation is needed, they may refer you to a pediatric endocrinologist.
