Irregular menstrual cycle?


Hello Dr.
Mao,
I would like to ask you the following questions:
1.
I have an enlarged thyroid (but no hyperthyroidism or hypothyroidism issues).
Will this affect the regularity of my menstrual cycle?
2.
My menstrual cycle is irregular (sometimes less than 28 days, sometimes more than 35 days).
Does this have any impact on my health? Why is my menstrual cycle not regular?
3.
Recently, I did not get my period (not due to pregnancy), so I consulted a gynecologist who prescribed me a 7-day course of hormone medication (Provera, 5mg).
How long will it take for my period to come? If it does not come, what could be the possible reasons?
4.
If I have not had sexual intercourse for a while and then resume, I experience pain during intercourse.
What could be the underlying issue?
Thank you.

Hello: 1.
Changes in thyroid function can affect the menstrual cycle.
2.
If the menstrual cycle is irregular each time, it may be due to hormonal factors, and it is necessary to investigate the underlying cause for appropriate treatment.
3.
Generally, if menstrual induction medication is taken, menstruation should occur within a week; if it has not occurred after two weeks, further investigation is needed to determine the cause.
4.
It may be related to dryness and lack of lubrication.

Understanding irregular menstrual cycles can be complex, as they can be influenced by a variety of factors, including hormonal imbalances, underlying health conditions, and lifestyle choices. Let's break down your questions one by one.

1. Thyroid Issues and Menstrual Irregularities: Thyroid dysfunction, even in the absence of hyperthyroidism or hypothyroidism, can still impact menstrual cycles. The thyroid gland plays a crucial role in regulating metabolism and hormonal balance in the body. An enlarged thyroid (goiter) may indicate an underlying issue, such as autoimmune thyroid disease, which can affect menstrual regularity. If your thyroid hormones are not balanced, it can lead to irregular cycles, as the hypothalamus and pituitary gland, which control the menstrual cycle, are sensitive to thyroid hormone levels.

2. Impact of Irregular Cycles on Health: Irregular menstrual cycles can have various implications for your health. They may indicate hormonal imbalances, such as polycystic ovary syndrome (PCOS), stress, significant weight changes, or other underlying health issues. Irregular cycles can also affect fertility, as ovulation may not occur consistently. If your cycles are consistently shorter than 21 days or longer than 35 days, it may be beneficial to consult with a healthcare provider for further evaluation.

3. Hormonal Treatment and Menstrual Return: Provera (medroxyprogesterone acetate) is a synthetic form of progesterone that is often prescribed to help regulate menstrual cycles. After taking Provera, you can typically expect your period to start within a few days to two weeks after completing the medication. If your period does not return after this time, it could be due to several factors, including hormonal imbalances, stress, or other underlying conditions that may need further investigation.

4. Pain During Intercourse: Experiencing pain during intercourse, especially after a period of abstinence, can be attributed to several factors. It could be due to insufficient lubrication, which is common if there has been a lack of sexual activity. Other potential causes include vaginal infections, pelvic inflammatory disease, or even conditions like endometriosis or fibroids. If the pain persists, it is important to consult with a healthcare provider for a thorough evaluation.

In summary, irregular menstrual cycles can be influenced by various factors, including thyroid health, hormonal imbalances, and lifestyle changes. It is essential to monitor your symptoms and consult with a healthcare provider for personalized advice and treatment options. Regular check-ups and open communication with your doctor can help you manage your menstrual health effectively. If you have concerns about your menstrual cycle or any associated symptoms, do not hesitate to seek medical advice for a comprehensive evaluation.
