Abnormal uterine bleeding (AUB) can be unsettling and disruptive, and it’s important to know when it’s a sign that you should contact your healthcare provider. At Grace Obstetrics & Gynecology, we understand that bleeding patterns vary, but certain changes can indicate an underlying issue that requires evaluation. This guide explains what constitutes abnormal uterine bleeding, its potential causes, and when to call your doctor.
What Is Abnormal Uterine Bleeding?
Abnormal uterine bleeding refers to bleeding from the uterus that is irregular in timing, amount, or duration compared to your usual menstrual cycle. While every woman’s cycle is different, bleeding is considered abnormal if it is:
- Heavier or lighter than normal
- Occurring more frequently than every 21 days or less frequently than every 35 days
- Lasting more than 7 days
- Associated with passing large blood clots
- Happening between periods or after menopause
Common Causes of Abnormal Uterine Bleeding
AUB can result from many different factors, including:
- Hormonal imbalances (often related to ovulation changes, perimenopause, or thyroid issues)
- Uterine fibroids or polyps
- Endometrial hyperplasia or endometrial cancer
- Bleeding disorders or medication side effects
- Pregnancy-related complications such as miscarriage or ectopic pregnancy
- Pelvic inflammatory disease (PID) or other infections
When to Call Your Doctor
You should seek medical evaluation for abnormal uterine bleeding if you experience any of the following:
- Heavy bleeding soaking through one or more pads/tampons every hour for several consecutive hours
- Bleeding between periods, after sex, or after menopause
- Periods lasting longer than 7 days or occurring unusually close together
- Severe pelvic pain or cramping alongside bleeding
- Dizziness, fainting, or signs of anemia (fatigue, shortness of breath, pale skin)
- Bleeding during pregnancy
Why Prompt Evaluation Matters
Early diagnosis can help identify and treat the underlying cause before it leads to more serious health issues, such as severe anemia or reproductive complications. Your provider may recommend diagnostic tools such as ultrasound, hysteroscopy, or endometrial biopsy to find the cause of your symptoms.
