What Causes of Blood Clots During Period?

Passing blood clots during menstruation is common but can feel alarming. Though usually normal, recurring large clots may signal health issues. This blog post explores the most common reasons you might pass clots during your period, including flow rate changes, age, contraceptives, fibroids, and coagulation disorders. Identifying the root cause of menstrual clotting allows you to determine when it’s normal and when you should see a doctor. You’ll also find tips to help manage or prevent clots.

What Causes of Blood Clots During Period?

During menstruation, the shedding of the uterine lining can sometimes lead to blood clots. Here are some common causes of blood clots during your period:

1. Heavy Menstrual Flow

Blood clots are more likely to form during heavy menstrual bleeding (menorrhagia). When the blood flow exceeds the body’s ability to produce anticoagulants quickly enough, clots can form.

2. Longer Menstrual Periods

Extended periods allow blood to remain in the uterus longer, which may lead to clotting before the blood is expelled.

3. Hormonal Imbalances

Imbalances in estrogen and progesterone levels can affect the uterine lining, causing it to shed unevenly during menstruation and leading to clot formation.

4. Uterine Fibroids

Noncancerous growths in the uterus, known as fibroids, can cause heavier or abnormal menstrual bleeding, including the formation of larger clots.

5. Endometriosis

This condition involves tissue similar to the uterine lining growing outside the uterus, which can lead to heavy bleeding and clots during periods.

6. Adenomyosis

Adenomyosis occurs when endometrial tissue grows into the uterine muscle, causing heavy, painful periods and potentially larger blood clots.

7. Age

Women approaching menopause may experience hormonal changes that result in heavier periods and blood clots. Similarly, teenagers who have recently started menstruating can have irregular hormonal levels, leading to clotting.

8. Reproductive Health Issues

Certain reproductive health issues, such as polycystic ovary syndrome (PCOS) or thyroid disorders, can also influence menstrual flow and clotting.

9. Lifestyle Factors

Obesity, smoking, and a sedentary lifestyle have been linked to heavier menstrual bleeding and the formation of clots.

How Can I Differentiate Normal vs Abnormal Clots?

While it’s important to be aware of potential health issues, it’s crucial to avoid self-diagnosing based on symptoms alone. Differentiating between normal and abnormal blood clots can be complex and requires medical expertise. However, I can share some general information to help you understand the key differences:

Normal Clots (During Menstruation):

• Size: Typically smaller than a quarter in diameter.
• Frequency: Occasional, usually occurring at the beginning of the menstrual cycle.
• Color: Usually bright red or brown in color.
• Texture: May have a smooth or jelly-like texture.
• Symptoms: May be accompanied by mild cramps or discomfort, but not typically severe pain, swelling, or other concerning symptoms.

Potential Abnormal Clots:

• Size: Larger than a quarter in diameter.
• Frequency: More frequent than usual, occurring throughout the menstrual cycle or even outside of menstruation.
• Color: May be purple, gray, orange, or black in color.
• Texture: May have a firm or rubbery texture.
• Symptoms: May be accompanied by severe pain, swelling, redness, warmth, or tenderness in the affected area, along with difficulty walking or breathing (if the clot occurs in the legs or lungs).

Symptoms of Blood Clots During Period

Here are some key symptoms and features associated with blood clots during menstruation:

1. Visible Clots

The most obvious symptom is the physical appearance of blood clots in your menstrual flow. These clots can vary in size and color, ranging from bright red to dark brown.

2. Heavy Menstrual Bleeding

Blood clots are often accompanied by heavy menstrual bleeding or menorrhagia. This might mean soaking through one or more sanitary pads or tampons every hour for several consecutive hours.

3. Menstrual Pain

While menstrual cramps are common, the presence of clots can sometimes be associated with more intense or prolonged pelvic pain and discomfort during your period.

4. Extended Period Duration

Periods that last longer than the average five to seven days, especially when accompanied by heavy bleeding and clots, can be a symptom worth noting.

5. Irregular Menstrual Cycles

Irregularities in your menstrual cycle, such as cycles that are shorter than 21 days or longer than 35 days, might also accompany the presence of blood clots.

6. Increased Fatigue

Heavy menstrual bleeding with clots can lead to iron loss and anemia, which may result in increased fatigue, weakness, and shortness of breath.

7. Large Clots

Noticing large clots (bigger than a quarter) consistently during your periods is a symptom that should not be overlooked.

Prevention and Treatment

If you’re looking to reduce the likelihood of blood clots during your period or alleviate associated symptoms, here’s what you can do:

• Stay Hydrated: Keeping yourself well-hydrated can help prevent blood from thickening and clotting excessively.
• Maintain a Balanced Diet: Incorporating foods rich in iron and vitamin K into your diet can promote healthy blood clotting.
• Stay Active: Regular physical activity can improve circulation, reducing the chances of blood pooling and clot formation.
• Consider Birth Control: Hormonal birth control methods can help regulate your menstrual cycle and decrease clotting.

When it comes to treatment options for blood clots during your period, some possible avenues include:

• Medications: Your healthcare provider might recommend medications like hormonal therapy to manage clotting issues.
• Iron Supplements: If heavy bleeding is leading to anemia, iron supplements may be prescribed to boost iron levels.
• Surgery: In severe cases, surgical procedures may be necessary to address underlying causes of blood clots.

Is It Safe?

In most cases, experiencing blood clots during your period is perfectly safe and a normal part of the menstrual process. During menstruation, the body sheds the uterine lining along with blood. Anticoagulants released by the body naturally prevent the menstrual blood from clotting. However, during a heavy flow, blood can be expelled faster than the anticoagulants can act, leading to the formation of clots. These are usually small, similar in size to a quarter or smaller, and dark red or brown.

When to Worry

It’s important to monitor the size and frequency of the clots. Large clots (bigger than a quarter) or a significant increase in clotting, especially if accompanied by other symptoms like heavy menstrual bleeding (menorrhagia), severe cramps, or periods lasting longer than 7 days, could indicate an underlying health issue that might require medical attention.

Frequently Asked Questions

Is it normal to pass blood clots during your period?

Passing small to medium blood clots during menstruation is generally normal. However, seek medical attention if you pass blood clots larger than a quarter.

When should I be concerned about period blood clots?

If you experience frequent heavy bleeding that requires changing pads or tampons every 2 hours or pass blood clots larger than a quarter, it’s advisable to consult a doctor for evaluation.

What are the treatment options for heavy menstrual bleeding with blood clots?

Treatment options vary based on individual symptoms and may include iron supplements, hormone therapy, medications, or surgery to manage heavy menstrual bleeding with blood clots.

Can passing large blood clots during your period lead to anemia?

Prolonged heavy bleeding with large blood clots can result in anemia due to blood loss. Seeking medical evaluation and appropriate treatment is crucial to prevent complications like anemia.
