Is It Normal for a 14-Year-Old to Miss Menstruation for Over Six Months? - Obstetrics and Gynecology

Menstruation has not occurred for a long time?


Hello doctor, I am 14 years old and I haven't had my period for over six months.
I previously researched online and found that it is common for some individuals during puberty to experience similar situations where their periods may not come for one to two years.
Is this normal for me, or should I see a doctor? Thank you.

It is recommended to visit a gynecology clinic for evaluation if you are experiencing irregular menstrual cycles.
Thank you.

It is not uncommon for young girls, especially those around the age of 14, to experience irregularities in their menstrual cycles. This can be particularly true during the early stages of menstruation, known as menarche, when cycles may not yet be regular. However, missing your period for over six months, known as amenorrhea, is something that should be evaluated by a healthcare professional.

During puberty, hormonal changes can lead to irregular periods. Many girls may experience cycles that are longer or shorter than the typical 28-day cycle, and it is not unusual for some to skip periods altogether. This can be due to a variety of factors, including stress, significant weight changes (either gain or loss), excessive exercise, or underlying health conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders.

While it is true that some girls may not have regular menstrual cycles for a year or two after they first start menstruating, a gap of six months is significant enough to warrant a visit to a doctor. A healthcare provider can perform a thorough evaluation, which may include a physical examination, a review of your medical history, and possibly some blood tests to check hormone levels and rule out any underlying conditions.

In addition to hormonal imbalances, other factors such as emotional stress, lifestyle changes, and even certain medications can affect menstrual cycles. If you have experienced any significant changes in your life, such as moving to a new school, changes in your family dynamics, or increased academic pressure, these could also contribute to your missed periods.

It is important to remember that while some irregularity can be normal, prolonged absence of menstruation can sometimes indicate a more serious issue that needs to be addressed. Conditions like hypothalamic amenorrhea, where the hypothalamus stops signaling the ovaries to produce hormones, can occur due to stress or low body weight.
In summary, while some irregularity in menstrual cycles is common during adolescence, missing your period for over six months is not typical and should be discussed with a healthcare provider. They can help determine the cause and provide guidance on how to manage your menstrual health moving forward. It’s always best to err on the side of caution when it comes to health concerns, especially during the formative years of adolescence.
