Menstrual blood clot issues?


Hello, doctor.
I am 27 years old, underweight, and have no anemia.
Last year, I underwent abdominal and transvaginal ultrasounds, which showed no uterine fibroids or abnormalities.
I also had a Pap smear, which indicated inflammation.
My menstrual cycle is very regular and punctual, but recently, I have been experiencing blood clots on days 3 to 5 of my cycle, varying in size and quantity, with a heavier menstrual flow sometimes accompanied by mild abdominal pain, although most of the time I don't feel anything.
I don't recall having this many blood clots before.
Due to my job, I sit for long periods and exercise infrequently.
I also avoid cold foods and drink room temperature beverages even in summer.
Doctor, do you think I need to go back to the hospital for further examination? Can prolonged sitting lead to an increase in blood clots? Thank you, doctor.

Dr. Lin Xinwang reply Obstetrics and Gynecology


Hello: A normal menstrual period lasts 2 to 7 days, with menstrual blood volume less than 80ml.
If there are blood clots, it indicates a heavier menstrual flow.
It is recommended to consult a physician for medication to regulate the menstrual cycle or to undergo further evaluation, such as an endometrial examination.

More Info


When it comes to understanding blood clots during menstruation, it's essential to recognize that while some clotting can be normal, significant changes in your menstrual cycle warrant further investigation. Given your age, medical history, and the recent changes you've described, it would be prudent to seek medical advice.


Understanding Menstrual Blood Clots
Menstrual blood can sometimes contain clots, which are typically small and not a cause for concern. However, larger clots (generally considered to be larger than a quarter) or an increase in the frequency and size of clots can indicate underlying issues. In your case, experiencing larger clots and heavier menstrual flow, especially if accompanied by abdominal pain, could suggest several possibilities:
1. Hormonal Imbalances: Conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders can lead to heavier menstrual bleeding and clotting.


2. Uterine Conditions: Although your previous ultrasounds did not show any abnormalities, conditions such as endometriosis or adenomyosis can develop over time and may not have been present during your last examination.

3. Blood Disorders: Conditions affecting blood clotting, such as von Willebrand disease or other clotting factor deficiencies, can lead to heavier menstrual bleeding and clotting.

4. Lifestyle Factors: Long periods of sitting, as you mentioned due to work, can contribute to poor circulation, which may exacerbate clotting issues. However, this is more commonly associated with venous thromboembolism (VTE) rather than menstrual clots.


When to Seek Medical Advice
Given your situation, here are some guidelines on when to seek medical advice:
- Increased Clot Size or Frequency: If you notice that the size or frequency of the clots is increasing, it is advisable to consult a healthcare provider.


- Heavy Bleeding: If you find yourself needing to change your menstrual products every hour or passing large clots consistently, this is a sign to seek medical attention.

- Severe Pain: While mild discomfort can be normal, severe abdominal pain that disrupts your daily activities should be evaluated.

- Changes in Cycle: Any significant changes in your menstrual cycle, such as the onset of heavy bleeding or clots after a period of regularity, should be discussed with a healthcare professional.


Recommendations
1. Consult a Gynecologist: Given your symptoms, it would be wise to schedule an appointment with a gynecologist. They may recommend further tests, such as blood tests to check for clotting disorders or a repeat ultrasound to assess for any new developments in your uterus.

2. Lifestyle Modifications: Incorporating regular physical activity can improve circulation and overall health. Consider integrating light exercises or stretching into your daily routine, especially if you have a sedentary job.

3. Monitor Symptoms: Keep a detailed record of your menstrual cycle, noting the size and frequency of clots, the heaviness of your flow, and any associated symptoms like pain. This information will be valuable for your healthcare provider.

4. Diet and Hydration: Ensure you are maintaining a balanced diet rich in iron and vitamins, which can help with overall menstrual health. Staying hydrated is also crucial.

In conclusion, while some clotting during menstruation can be normal, the changes you've described suggest that a medical evaluation is warranted. Early intervention can help address any underlying issues and improve your menstrual health.
