Short Menstrual Cycles: Causes and Solutions for Women

What should I do?

Hello Doctor: Since October of last year, my menstrual flow has decreased in duration.
I have been getting my period every month, but it only lasts for two days.
The first day has a heavy flow, and by the second day, it is very light (almost like it is ending).
This situation has persisted from October of last year until now.
In April of this year, I visited a gynecologist, and blood tests revealed that I have polycystic ovary syndrome (PCOS).
From April to now, I have been taking one pill of Metformin every night before bed for about six months, but my menstrual cycle still only lasts for two days.
I read news reports stating that a decrease in menstrual flow could indicate early ovarian failure, and I am concerned about potential fertility issues.
Could you please advise me on what methods I can use to conduct more detailed examinations of my uterus and ovaries to identify the underlying problems? Thank you very much for your help!

Polycystic ovarian cysts can indeed lead to decreased ovarian function and lower fertility rates.
For younger individuals who have not yet conceived, the treatment approach should be more proactive, aiming to facilitate early pregnancy.
This not only addresses the condition but also provides peace of mind, as having conceived and given birth can be reassuring even if ovarian function declines further in the future.
A detailed discussion should take place after an outpatient examination.

More Info

Understanding short menstrual cycles and their implications can be quite complex, especially when considering conditions like polycystic ovary syndrome (PCOS) and the potential for ovarian insufficiency. Your experience of having a menstrual cycle that lasts only two days, with heavy flow on the first day and minimal flow on the second, is indeed concerning and warrants further investigation.

Causes of Short Menstrual Cycles
1. Hormonal Imbalances: The menstrual cycle is regulated by a delicate balance of hormones, including estrogen and progesterone. In conditions like PCOS, the hormonal balance can be disrupted, leading to shorter cycles or changes in flow.

2. Ovarian Function: Early ovarian insufficiency or premature ovarian failure can lead to changes in menstrual patterns. This condition can cause the ovaries to stop functioning properly before the age of 40, which can affect fertility.

3. Stress and Lifestyle Factors: High levels of stress, significant weight changes, excessive exercise, or poor nutrition can also impact menstrual cycles. These factors can lead to hormonal imbalances that may result in shorter cycles.

4. Underlying Health Conditions: Other health issues, such as thyroid disorders or uterine abnormalities, can also affect menstrual cycle length and flow.

Solutions and Next Steps
1. Comprehensive Evaluation: Since you have already been diagnosed with PCOS, it is essential to have a thorough evaluation of your ovarian function. This may include:
- Transvaginal Ultrasound: This imaging test can help visualize the ovaries and check for cysts or other abnormalities.

- Hormonal Testing: Blood tests to measure levels of hormones such as FSH, LH, estradiol, and testosterone can provide insight into ovarian function and hormonal balance.

2. Consultation with a Specialist: If you haven’t already, consider consulting a reproductive endocrinologist. They specialize in hormonal disorders and fertility issues and can provide a more detailed assessment of your reproductive health.

3. Lifestyle Modifications: Maintaining a healthy lifestyle can help manage PCOS symptoms. This includes:
- Balanced Diet: Focus on a diet rich in whole foods, lean proteins, healthy fats, and plenty of fruits and vegetables. Reducing processed foods and sugars can help manage insulin levels, which is crucial in PCOS.

- Regular Exercise: Engaging in regular physical activity can help regulate menstrual cycles and improve overall health.

- Stress Management: Techniques such as yoga, meditation, or counseling can help reduce stress, which may positively impact your menstrual cycle.

4. Medication Review: You mentioned taking a medication called "泌樂寬" (likely a form of hormonal therapy). It’s important to discuss with your doctor whether this medication is appropriate for your situation and if adjustments are needed. Sometimes, different medications or dosages may be required to achieve better hormonal balance.

5. Fertility Considerations: If you are concerned about fertility, it may be beneficial to discuss this with your healthcare provider. They can provide options for fertility preservation or treatments that may help regulate your cycles and improve your chances of conception.

Conclusion
Your concerns about short menstrual cycles and their implications for fertility are valid and important. It is crucial to pursue further evaluation and work closely with your healthcare provider to understand the underlying causes and explore appropriate treatment options. By addressing hormonal imbalances and making lifestyle changes, you may be able to improve your menstrual health and overall well-being. Remember, you are not alone in this journey, and seeking support from healthcare professionals can make a significant difference.
