Q: Changes in Menstrual Cycle: When to Seek Further Evaluation?

Hello： Dysmenorrhea or irregular menstruation should be evaluated through a medical examination. <br>Department of Obstetrics and Gynecology, Hsinchu Hospital.

The menstrual cycle has become slower?

Hello, I have had regular menstrual cycles of 28 days since menarche, but I experience dysmenorrhea on the first day and take one painkiller for relief.
I have previously consulted a gynecologist and underwent an ultrasound, which showed no signs of endometriosis.
However, since January of this year, my menstrual cycles have become irregular, occurring approximately every 35 days instead of the usual regularity.
Should I seek further evaluation? Thank you.

More Info

Changes in the menstrual cycle can be a source of concern for many women, especially when there is a notable shift from a previously regular pattern. In your case, you mentioned that your menstrual cycle was consistently 28 days, but since January, it has become irregular, extending to about 35 days. Additionally, you have experienced menstrual pain that requires pain medication, but you have previously been evaluated by a gynecologist who ruled out endometriosis through ultrasound.

Irregularities in the menstrual cycle can be caused by a variety of factors, including hormonal imbalances, stress, changes in weight, lifestyle modifications, or underlying medical conditions. Given that your cycle has shifted from a regular 28-day cycle to a 35-day cycle, it is essential to consider the following points:
1. Hormonal Changes: Hormonal fluctuations can significantly impact the menstrual cycle. Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, and perimenopause can lead to irregular cycles. If you have experienced other symptoms such as weight gain, acne, or excessive hair growth, it may be worth discussing these with your healthcare provider.

2. Stress and Lifestyle Factors: Stress, significant changes in weight (either gain or loss), and changes in physical activity can all affect your menstrual cycle. If you have experienced any life changes or stressors recently, this could be a contributing factor.

3. Age and Reproductive Health: If you are in your late 30s or early 40s, it is possible that you are entering perimenopause, which can cause irregular cycles. However, if you are younger, it is less likely to be the cause.

4. Pain Management: You mentioned experiencing menstrual pain that requires medication. While some discomfort is common during menstruation, severe pain could indicate other underlying issues, such as fibroids or adenomyosis, which may require further evaluation.

5. Follow-Up with a Healthcare Provider: Since your menstrual cycle has changed and you have a history of menstrual pain, it would be prudent to follow up with your gynecologist or healthcare provider. They may recommend further evaluation, such as blood tests to check hormone levels, or additional imaging studies to rule out any structural abnormalities.

In summary, while occasional changes in the menstrual cycle can be normal, persistent irregularities warrant further investigation, especially if accompanied by significant pain or other symptoms. It is advisable to schedule an appointment with your healthcare provider to discuss your concerns and determine if any further evaluation is necessary. They can provide personalized guidance based on your medical history and current symptoms, ensuring that any potential issues are addressed promptly.
