Abnormal uterine bleeding (AUB) refers to any bleeding that is different from normal monthly periods.¹ Normal periods occur at an interval of 24 to 38 days, last for 2 to 7 days and result in a blood loss of 5 to 80 mL.² You may experience changes with respect to the regularity, duration, frequency or volume of blood flow during periods.³ If you notice changes in any of these parameters, you may have abnormal uterine bleeding.² However, if you experience periods with abnormally heavy bleeding or longer duration of bleeding, you might have heavy menstrual bleeding (HMB). .⁴

Abnormal uterine bleeding occurs in about one-third of women in their life, with irregularities most commonly occurring at menarche (first occurrence of periods) and perimenopause (around the time of menopause; menopause means permanent end of periods).²

In India, around 18% of women have abnormal uterine bleeding.⁵ It can affect the quality of social, mental and emotional health of women to a great extent.⁶
