Irregular Menstrual Cycles: Is It Hormonal Imbalance?

Is it an endocrine disorder?

Hello doctor, my last menstrual period started on March 27th, but it hasn't completely stopped until today.
The flow has been light every day, and I haven't experienced any menstrual cramps.
I'm wondering if this could be classified as "abnormal bleeding." My period in February started on the 22nd, and I'm concerned if my current situation might be due to hormonal imbalance.
What could cause hormonal imbalance? Do I need to undergo an ultrasound examination? At my age, is it concerning that my menstrual cycle is still so irregular? I hope you can provide some insights.
Thank you.

1.
The menstrual period lasting from March 27 to April 12 is a bit prolonged, but there are many reasons for menstrual irregularities, including exercise, travel, medications, and weight loss.
2.
It is appropriate to start with an ultrasound examination.
3.
Occasionally, menstrual irregularities can occur due to anovulation, so there is no need to worry too much.
If you have further questions, please visit a gynecology clinic for an evaluation.

More Info

Irregular menstrual cycles can indeed be a source of concern for many individuals, and your situation raises several important points regarding hormonal balance and potential underlying issues. Based on your description, it sounds like you are experiencing prolonged menstrual bleeding, which can be classified as abnormal uterine bleeding (AUB). This condition can arise from various factors, including hormonal imbalances, structural abnormalities in the uterus, or other medical conditions.

Hormonal imbalances are a common cause of irregular menstrual cycles. The menstrual cycle is regulated by a complex interplay of hormones, primarily estrogen and progesterone, which are produced by the ovaries. Disruptions in the levels of these hormones can lead to irregularities in the menstrual cycle, including prolonged bleeding, missed periods, or heavy bleeding. Factors that can contribute to hormonal imbalances include stress, significant weight changes (either loss or gain), excessive exercise, and underlying medical conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders.

In your case, the fact that your last menstrual period started on March 27 and has not fully stopped yet, combined with the irregularity of your cycles (with the previous one starting on February 22), suggests that there may be an underlying hormonal issue. It is important to note that while some irregularities can be normal, especially in younger individuals as their bodies are still regulating hormonal cycles, persistent or significant changes warrant further investigation.

Regarding the need for an ultrasound examination, it can be a useful diagnostic tool to assess the structure of the uterus and ovaries. An ultrasound can help identify any abnormalities such as fibroids, polyps, or ovarian cysts that could be contributing to your symptoms. Additionally, it can provide insight into the thickness of the uterine lining, which can be relevant in cases of prolonged bleeding.

At your age, while some irregularity can be expected, especially during the first few years after menarche (the first menstrual period), it is essential to monitor your symptoms closely. If you continue to experience prolonged bleeding or if the bleeding becomes heavy, it is advisable to consult a healthcare provider for a thorough evaluation. They may recommend blood tests to check hormone levels, a pelvic exam, and possibly imaging studies like an ultrasound.

In summary, while hormonal imbalances are a likely cause of your irregular menstrual cycles, it is crucial to seek medical advice to rule out other potential issues. Keeping a record of your menstrual cycles, including the duration and flow, can be helpful for your healthcare provider in diagnosing the issue. Early intervention can lead to better management of your symptoms and overall reproductive health.
