Connecting Abnormal Uterine Bleeding to My Symptoms

Record when and how much you bled using numbers and behaviors

On a calendar, note the start and end dates of bleeding and how it differs from your usual period. Record the interval between changing pads or tampons, the number of times you leaked at night, and any large blood clots or pain. Distinguish whether it occurred after intercourse or between periods. Even if you cannot measure the exact amount of blood, noting changes in your daily activities helps in determining the need for anemia tests and other examinations.

Stopping the bleeding and finding the cause are done together

If there is sudden heavy bleeding, blood pressure, pulse, anemia, and the possibility of pregnancy are checked first, and treatment to control the bleeding is provided if necessary. Once the condition is stable, blood tests, ultrasound, and endometrial evaluations may be considered depending on age and symptoms. Please disclose all use of anticoagulants, aspirin, hormone medications, and intrauterine devices (IUDs).

Herbal medicine treatment plans are categorized based on the pattern of bleeding and the speed of recovery

In Korean medicine treatment, we distinguish whether bright red bleeding occurs alongside heat sensations and thirst, whether small amounts of bleeding persist longer when fatigued, whether bleeding stops and restarts along with blood clots and pelvic pain, or whether dizziness, throbbing, and insomnia remain after bleeding. While continuing treatment for the cause identified through examinations, we prioritize herbal medicine treatment according to the prominent combination of symptoms. Following treatment, we track the number of bleeding-free days, nighttime changes and large blood clots, and changes in hemoglobin alongside dizziness and fatigue in the same record.

Frequently Asked Questions

Common questions when looking into abnormal uterine bleeding

Is any spotting between periods considered abnormal uterine bleeding?

Bleeding between menstrual periods may be included in abnormal uterine bleeding, but there is more than one cause. We determine the necessary medical evaluation by checking for recurrence, timing of intercourse or ovulation, possibility of pregnancy, and medication use.

At what level of bleeding should I go to the emergency room?

If bleeding continues to the point where you must change pads or tampons every hour, and you experience chest pain, shortness of breath, severe dizziness, or a feeling that you might faint, seek emergency evaluation immediately. Do not wait if there is a possibility of pregnancy and bleeding is accompanied by severe pain.
