Irregular Menstrual Cycles: Causes and Solutions for Women

MC's issue?

Hello Dr.
Lin: Since I started my period in the seventh grade, I have only had my menstrual cycle every few months.
I often need to induce menstruation or take traditional Chinese medicine for a while to regulate it, but it gradually returns to infrequent cycles.
Is this considered oligomenorrhea (infrequent menstruation)? Am I at a higher risk for gynecological diseases or difficulties in conceiving? Is there a way to treat this to achieve a normal cycle? Thank you.

As long as the menstrual cycle remains regular, there is no need to worry too much.
When the body is under significant stress, lacks sleep, or experiences continuous weight loss, menstruation may be absent or infrequent.
This is a protective mechanism of the body to prevent further depletion of menstrual blood during times of poor health, which could impose a greater burden on the body.
Therefore, when planning to conceive, it is important to maintain a regular lifestyle, engage in moderate exercise and a balanced diet, keep weight stable and within a normal range, and manage stress levels.
At this time, ovarian function and ovulation will naturally return to normal.
If menstruation still does not normalize, ovulation medications can be used to assist with conception.
A regular menstrual cycle and normal ovulation function naturally reduce the risk of ovarian diseases.
It is essential to remember that ovarian function (reproductive function) can only manifest when the functions of other body parts are normal and when there is a regular and healthy routine.

Irregular menstrual cycles can be a source of concern for many women, especially when they experience prolonged periods between cycles or have to rely on medications or herbal remedies to induce menstruation. Your situation, where you have had irregular cycles since your first menstruation, raises several important points regarding potential causes, implications for reproductive health, and treatment options.

Firstly, it is essential to understand that irregular menstrual cycles can be classified into several categories, including oligomenorrhea (infrequent menstruation), amenorrhea (absence of menstruation), and polymenorrhea (frequent menstruation). Given your description, it sounds like you may be experiencing oligomenorrhea, which is defined as cycles that occur more than 35 days apart but less than six months apart.
The causes of irregular menstrual cycles can vary widely and may include hormonal imbalances, stress, significant weight changes, excessive exercise, and underlying medical conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or even structural abnormalities in the reproductive system. Since you mentioned that your ultrasounds have been normal, it is less likely that there are structural issues, but hormonal imbalances could still be at play.

Regarding your concern about the potential for developing gynecological diseases or difficulties with conception, it is important to note that irregular cycles can sometimes be associated with conditions like PCOS, which can affect fertility. Women with irregular cycles may have difficulty predicting ovulation, which can make it challenging to conceive. However, not all women with irregular cycles will experience fertility issues, and many can conceive successfully with appropriate medical guidance.

As for treatment options, the approach often depends on the underlying cause of the irregular cycles. Here are some potential strategies:
1. Lifestyle Modifications: If stress, weight changes, or excessive exercise are contributing factors, addressing these through lifestyle changes can be beneficial. Regular exercise, a balanced diet, and stress management techniques can help regulate menstrual cycles.

2. Hormonal Treatments: For women with hormonal imbalances, hormonal contraceptives (like birth control pills) can help regulate the menstrual cycle. These medications can provide a consistent hormone level, leading to more regular cycles.

3. Medications for Ovulation Induction: If you are considering pregnancy and have difficulty ovulating, medications like Clomiphene citrate may be prescribed to stimulate ovulation.

4. Monitoring and Follow-Up: Regular follow-up with a healthcare provider is crucial. Keeping a menstrual diary can help track your cycles and any associated symptoms, which can provide valuable information for your healthcare provider.

5. Alternative Therapies: Some women find relief through acupuncture or herbal remedies, but it is essential to discuss these options with a healthcare provider to ensure they are safe and appropriate for your situation.

In conclusion, while irregular menstrual cycles can be concerning, there are various approaches to diagnosis and treatment. It is advisable to consult with a gynecologist or a reproductive endocrinologist who can provide a comprehensive evaluation and tailored treatment plan based on your specific circumstances. Regular monitoring and open communication with your healthcare provider will be key in managing your menstrual health effectively.
