Are your periods becoming heavier, longer, irregular or are you experiencing bleeding between periods? If yes, then it's important to not ignore these symptoms. Because these can signal abnormal uterine bleeding (AUB) also known as (menometrorrhagia).

Menometrorrhagia is not a disease itself, it is a symptom that can signal change in hormonal levels, uterine conditions such as fibroids or polyps, pregnancy-related issues, or, sometimes, precancerous or cancerous conditions. 

Fortunately, many causes of abnormal uterine bleeding are treatable. Therefore, consult a gynaecologist for detailed evaluation to identify the underlying root cause. This ensures prevention of complications such as anemia or delayed diagnosis of serious conditions.

Many women might dismiss heavier, longer, irregular periods and unusual bleeding as “it's just a stress," or "My hormones must be changing." Sometimes that's true. But, it's worth finding out the reason in a timely manner rather than simply waiting for the symptoms to settle.

What is Abnormal Uterine Bleeding?

Abnormal uterine bleeding (AUB) in medical terms known as menometrorrhagia. It refers to any bleeding from the uterus that differs from your normal menstrual cycle in terms of: 

  • Frequency
  • Duration
  • Regularity
  • Amount of blood loss

In simple terms, if bleeding during your periods doesn't follow your usual pattern or happens outside pregnancy, it can be considered abnormal menstrual bleeding.
