Decreased menstrual flow?

Your friend has been experiencing menstrual pain and has been taking Western medicine.
After starting traditional Chinese medicine in August, including concentrated herbal formulas (Gui Pi Decoction, Zuo Gui Pill, Wen Jing Decoction, and Shao Fu Zhu Yu Decoction), she noticed a decrease in menstrual flow and a change in color, which has made her hesitant to continue taking the medication.
Is this situation normal, or could it be a side effect of the medication, or is there another reason?

Dear user di1722,
In response to your question:
1.
Your friend has experienced a decrease in menstrual flow accompanied by dysmenorrhea and has been taking Western medicine.
In August of this year, she began taking concentrated Chinese herbal medicine (Gui Pi Decoction, Zuo Gui Pill, Wen Jing Decoction, and Shao Fu Zhu Yu Decoction).
Since she had only two menstrual periods from August to September, using four different formulas within eight weeks does not align with the principles of Traditional Chinese Medicine (TCM).
Generally, Chinese herbal medicine requires long-term treatment.
The frequent and arbitrary changes in prescriptions, each with different effects (such as tonifying the spleen, nourishing the kidneys, and promoting blood circulation), make it difficult to assess whether these medications are responsible for the reduced menstrual flow and lighter color.
Without adhering to TCM diagnostic principles and with no clear treatment direction, it is challenging to discuss the effectiveness of the treatment.
2.
It is also possible for this phenomenon to occur naturally without medication.
A woman's menstrual flow can vary each time.
Factors such as height, weight, and individual constitution can lead to naturally lighter menstrual flow, and conditions like hyperthyroidism can also cause decreased menstrual flow.
3.
In my clinical experience, addressing menstrual issues through a detailed diagnosis of "cold-heat, deficiency-excess" can lead to improvement.
I recommend a long-term treatment approach; however, it is essential to consult a qualified TCM practitioner for proper diagnosis and treatment.
Wishing you all the best,
Dr.

More Info

When it comes to understanding reduced menstrual flow, it is essential to consider various factors, including the medications being taken, underlying health conditions, and lifestyle changes. In your friend's case, the combination of Western medications and traditional Chinese herbal remedies may have contributed to the changes in menstrual flow.

Firstly, it is important to recognize that menstrual flow can be influenced by hormonal levels, which can be affected by medications. Nonsteroidal anti-inflammatory drugs (NSAIDs) commonly used for menstrual pain can sometimes lead to lighter periods due to their effects on prostaglandin levels, which play a role in regulating menstrual flow. If your friend has been taking such medications regularly, this could be a contributing factor to the reduced menstrual flow.

On the other hand, the use of Chinese herbal medicine, such as Gui Pi Tang and other formulas, can also impact menstrual flow. These herbal remedies are often used to nourish the blood and improve overall health, but they can also have varying effects on menstrual cycles depending on the individual's constitution and the specific herbs used. For instance, some herbs may have a tonifying effect, while others may help to regulate or even reduce menstrual flow. If your friend has noticed a significant change in the color and volume of her menstrual blood after starting these herbal treatments, it may be worth discussing with a healthcare provider who is knowledgeable about both Western and traditional Chinese medicine.

Additionally, lifestyle factors such as stress, diet, and exercise can also play a significant role in menstrual health. Stress, in particular, can lead to hormonal imbalances that may result in lighter periods or even missed cycles. If your friend has experienced increased stress or changes in her lifestyle, this could also be a contributing factor.

It is also important to consider any underlying health conditions that may affect menstrual flow. Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or uterine abnormalities can lead to changes in menstrual patterns. If your friend has a history of such conditions, it may be prudent for her to consult with a healthcare provider for a thorough evaluation.

In conclusion, while reduced menstrual flow can be a normal variation for some individuals, it can also be a side effect of medications or a sign of an underlying health issue. It is advisable for your friend to monitor her symptoms and consult with a healthcare provider to discuss her concerns. A healthcare professional can provide a comprehensive assessment, considering her medical history, current medications, and lifestyle factors, to determine whether the changes in her menstrual flow are normal or warrant further investigation.
