How is abnormal uterine bleeding defined?

• A. Bleeding at irregular intervals
• B. Bleeding only during menses
• C. Abnormal in volume, regularity, or timing for majority of last 6 months
• D. Bleeding only postmenopause

Answer: (C)

Abnormal uterine bleeding is defined by a change in how much bleeding occurs, how often it occurs, or when it starts, and this pattern should be seen across the majority of recent cycles. In practice, the standard definition uses a six-month window: if bleeding is abnormal in volume, regularity, or timing for the majority of cycles in the last six months, it’s considered AUB. This means that heavy or light bleeding, cycles that are irregular or unpredictable, or bleeding that begins at an unusual time relative to a patient’s usual pattern all count when they persist across most cycles. The other descriptions focus on only one aspect or on a specific situation, rather than capturing the overall pattern. For example, irregular intervals alone don’t address volume or persistency, and bleeding only during menses would not necessarily be abnormal. Bleeding restricted to the postmenopausal period is a red-flag scenario, but it isn’t the general definition of abnormal uterine bleeding.
