Menstrual blood clots


Hello, doctor.
In the past 3 to 4 months, during the second day of my menstrual period, I experience a sudden surge of heavy bleeding accompanied by large blood clots.
It feels like the blood is continuously flowing out, and during these episodes, there is almost no white area visible on the sanitary pad.
This situation occurs 1 to 2 times each month, but it resolves by the third day.
I have had blood clots during my periods in the past, but they were not as frequent or as numerous.
Could this indicate a problem with my uterus or another issue? Is this related to having genital warts? Should I seek medical attention? Thank you for your response.

Hello: There are many possible causes for increased menstrual flow, such as fibroids, adenomyosis, and endometrial hyperplasia, but they are less likely related to warts.
Please seek medical attention promptly.

More Info


Menstrual blood clots can be a common occurrence for many women, but when they become larger or more frequent, it can raise concerns about underlying health issues. Based on your description, it seems that you are experiencing significant changes in your menstrual cycle, particularly with the presence of large blood clots and heavy bleeding on the second day of your period. This situation warrants a closer examination to determine if there are any underlying conditions that need to be addressed.

Firstly, it is important to understand that menstrual blood clots are formed when blood pools in the uterus and thickens before being expelled. Small clots are typically normal, but larger clots (greater than the size of a quarter) can indicate a problem. Heavy menstrual bleeding, or menorrhagia, is defined as losing more than 80 milliliters of blood during a period or having periods that last longer than seven days. The symptoms you describe—sudden heavy bleeding accompanied by large clots—could be indicative of menorrhagia.

There are several potential causes for heavy menstrual bleeding and the presence of large clots, including:
1. Uterine Fibroids: These are noncancerous growths in the uterus that can cause heavy bleeding and clotting. They can vary in size and number, and their presence can significantly affect menstrual flow.

2. Endometriosis: This condition occurs when tissue similar to the lining of the uterus grows outside of it, leading to inflammation, pain, and heavy bleeding.

3. Hormonal Imbalances: Fluctuations in hormones, particularly estrogen and progesterone, can lead to changes in menstrual flow and clotting.

4. Adenomyosis: This condition occurs when the inner lining of the uterus breaks through the muscle wall of the uterus, leading to heavy bleeding and painful periods.

5. Coagulation Disorders: Conditions that affect blood clotting, such as von Willebrand disease or platelet disorders, can lead to heavier menstrual bleeding and larger clots.

6. Pelvic Inflammatory Disease (PID): An infection of the reproductive organs can lead to abnormal bleeding and clotting.

Regarding your question about whether this is related to "long cauliflower" (which I assume refers to genital warts or HPV-related issues), while HPV can lead to cervical changes and potentially cervical cancer, it is not directly linked to heavy menstrual bleeding or clotting. However, if you have concerns about HPV or any other sexually transmitted infections, it is essential to discuss these with your healthcare provider.

Given the changes you are experiencing, it is advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, which may include:
- A pelvic exam to check for any abnormalities.

- An ultrasound to visualize the uterus and check for fibroids or other structural issues.

- Blood tests to assess hormone levels and check for any clotting disorders.

- A biopsy if there are concerns about abnormal cells in the uterus or cervix.

In conclusion, while menstrual blood clots can be normal, the significant changes you are experiencing—especially the heavy bleeding and large clots—should be evaluated by a healthcare professional. Early diagnosis and treatment can help manage any underlying conditions and improve your menstrual health. Don't hesitate to reach out to your doctor to discuss your symptoms and get the care you need.
