Menstruation and Bleeding
Menstrual Blood Clots
Related terms: Clotted blood, menstrual blood clots
Menstrual blood clots occur when menstrual blood clumps together. Do not determine the cause based on the size of the clots alone; consider the frequency of changing menstrual products, nighttime changes, bleeding burden such as leaking, pain, dizziness, shortness of breath, and recovery after menstruation. If you experience bleeding that quickly soaks through a pad, dizziness, fainting, or shortness of breath, seek medical evaluation first.
Overview
Menstrual Blood Clots: Check these three things first
- Menstrual blood clots appear when blood clumps together while staying inside the uterus or on menstrual products; a clot alone is not used to diagnose a disease.
- Rather than focusing on the maximum width or frequency of clots, first observe if there are changes in the interval between changing menstrual products, nighttime changes, or leakage, and record the duration of bleeding, pain, and dizziness.
- Even if clots decrease, pain or fatigue after menstruation may remain. While managing the identified cause of bleeding, we determine whether the next goal should be reducing the burden of bleeding, pain, or recovery time.
Meaning and Distinctions
What are menstrual blood clots?
When dealing with menstrual blood clots, it is important to look at the interval between changing menstrual products, nighttime bleeding, pain, dizziness, and recovery after menstruation, rather than the clots themselves. Menstrual blood clots occur when menstrual blood clumps together. Do not judge the cause based on clot size alone; consider the overall burden of bleeding (such as product change intervals, nighttime changes, and leakage), pain, dizziness, shortness of breath, and recovery after menstruation. If you experience bleeding that quickly soaks through a pad, or dizziness, fainting sensations, or shortness of breath, seek medical evaluation first.
- Easily confused terms
- A blood clot alone is not used to diagnose uterine fibroids or Adenomyosisother conditions. We check not only the maximum width and frequency but also whether the total amount of bleeding, pain, pelvic pressure, and post-menstrual fatigue have changed from usual.
- Why this is checked during medical evaluation
- If large clots recur while the change interval shortens, or if you wake up at night and experience leakage on clothes or bedding, the actual burden of bleeding has increased. By checking for pain, dizziness, shortness of breath, and delayed recovery, Anemiawe determine whether a bleeding cause evaluation is the priority or if we should adjust the remaining discomfort following previous treatments.
- What to record for your visit
- Please record the bleeding days for the last 3 cycles, the size of the largest clot and daily frequency, the interval between changing menstrual products, nighttime changes, leakage, days of pain, and the time it took to recover from dizziness and fatigue after menstruation. Please also provide the date and a list of any possibility of pregnancy, ultrasound or blood test results, and any contraceptive pills, intrauterine devices, anticoagulants, Korean herbal medicine, or supplements during your visit.

Connecting Menstrual Blood Clots to Your Symptoms
You can record symptoms using consistent units even without taking photos
Record the days and frequency of clots, and measure the maximum width with a ruler or compare it to a consistent household object. Recording how many hours passed between changing menstrual products, whether you woke up at night to change, and whether it leaked onto clothes or bedding provides a better representation of the actual bleeding burden than recording clots alone.
Blood stasis or diseases are not confirmed by color and clots alone
Even if there are dark clots and pain, Uterine Fibroidsthere may be various causes such as adenomyosis, irregular ovulation cycles, PCOS, thyroid changes, or medications. First, check recent ultrasound and blood tests, as well as changes in the menstrual cycle, and observe if the clots increase every month.
Clots, pain, and recovery may not improve at the same rate
We plan Korean medicine treatment while continuing necessary gynecological evaluations and anemia treatment. We distinguish whether pain or pelvic pressure remains even if clots and nighttime changes have decreased, or if dizziness, throbbing, and loss of energy persist long after bleeding even if pain has lessened. After treatment, we determine the next goal by checking the product change interval, clot frequency, days of pain, and daily recovery time using the same criteria.
Frequently Asked Questions
Frequently Asked Questions about Menstrual Blood Clots
Are all menstrual blood clots a sign of uterine fibroids?
No. They may appear temporarily on days with heavy bleeding. We evaluate the recurring size and frequency, changes in menstrual volume, pain, and cycle, along with necessary evaluations such as ultrasounds.
Can I keep the records necessary for my medical evaluation without taking photos?
Yes, you can. Please record the maximum width of the clots, the number of times they occur per day, the interval between changing sanitary products, and whether you need to change them at night or if they leak, using a consistent standard.
What is the goal of Korean medicine treatment for menstrual blood clots?
The goal is not described simply as removing the clots. While respecting the identified cause of bleeding and existing treatments, we plan Korean herbal medicine and acupuncture treatments by prioritizing among menstrual volume, pain, cycle, and the fatigue or dizziness following bleeding.
If the clots have decreased but pain or post-menstrual fatigue remains, what should be monitored?
The burden of bleeding, pain, and recovery can change at different rates. Please separately record the interval between changing sanitary products, nighttime changes, the number of days with pain, and the time it takes for post-menstrual dizziness and fatigue to recover, and determine the remaining goals during your next medical evaluation.

- Condition GuideAbnormal Uterine BleedingAbnormal uterine bleeding is bleeding that occurs at a different time, amount, or duration than the expected period. This includes spotting between periods or after sexual intercourse, bleeding that lasts more than 7 days, cases where the cycle changes significantly, and postmenopausal bleeding. If there is a possibility of pregnancy and bleeding occurs with pelvic pain, or if menstrual products are soaked through every hour for more than 2 hours accompanied by dizziness, difficulty breathing, or chest pain, an emergency evaluation takes priority over a consultation regarding the cause.→
- Condition GuideAdenomyosisSymptoms of adenomyosis may include menstrual cramps severe enough to disrupt daily life, heavy or prolonged menstruation with large blood clots, pelvic pain or dyspareunia (pain during intercourse) regardless of the cycle, and a feeling of heaviness in the lower abdomen. In some cases, there are almost no symptoms, and because it is similar to uterine fibroids or endometriosis, a definitive diagnosis is not made based on symptoms alone. If heavy bleeding causes dizziness, shortness of breath, or severe fatigue, anemia must be checked. Even if pain has decreased, if low energy after menstruation or pelvic pressure remains, the treatment goal must be re-evaluated to see if it has moved to the next stage. At Baekrokdam, we first distinguish between acute excessive bleeding and necessary gynecological exams, then provide consultations for chronic or recurring pain, bleeding, and loss of vitality through Korean herbal medicine treatment.→
- Medical Evaluation GuideWhat should I check first when menstrual pain and bleeding change?First, check if the pain is more severe than usual, if bleeding has increased or occurred between periods, or if there is a possibility of pregnancy. If you experience bleeding that requires changing menstrual products every hour, dizziness as if you might faint, shortness of breath, or if you have one-sided pelvic pain, shoulder pain, and bleeding along with a possibility of pregnancy, you must be evaluated immediately without waiting for your next appointment. If it is not an urgent situation, please record not only the pain level but also any preceding changes, such as a feeling of blockage in the solar plexus, constipation, or cravings for sweets before menstruation, to help narrow down the treatment questions more quickly.→
