Irregular menstrual periods

Fact Checked

Irregular menstrual periods refer to menstrual bleeding that occurs between menstrual periods. Irregular menstrual periods also mean that you are not having periods at regular intervals. A woman’s menstrual period occurs due to internal changes involving the hormones. A slight hormonal change may result in the commencement of menstrual periods and/or the menstrual periods becoming abnormal. It is normal to have menstrual periods for a period of 3-5 days. Normally women lose less than 1 cup of blood during their menstrual period – the amount of blood lost does not affect your health. Irregular menstrual bleeding may occur due to causes such as dysfunctional uterine bleeding.

A woman having irregular menstrual periods may experience menstrual bleeding between her normal menstrual periods. Irregular intervals may be more than 35 days between menstrual periods, less than 21 days between menstrual periods or prolonged menstrual periods – periods that last for more than 7 days.

If you report your condition to your doctor or gynecologist, he or she may consider treatment deepening on the cause. Treatment usually includes oral contraceptives and occasionally dilation and curettage (D and C) in case of prolonged or severe menstrual bleeding.
