Dysfunctional uterine bleeding is a common disorder marked by an irregular uterine bleeding that is found in the absence of structural pelvic pathology, pregnancy or general medical disease.
• The bleeding is unpredictable, it may be excessively heavy or light and may be frequent, random or prolonged.
• The condition affects nearly every woman at some point in their life.
• Dysfunctional uterine bleeding can impact your life in a negative way. Not being aware of when the bleeding will start can cause anxiety and heavy menstrual bleeding may limit daily activities during period.
• It is usually a menstrual disorder, although it is possible for the uterus to bleed abnormally outside menstruation.
• Dysfunctional uterine bleeding can be classified as ovulatory or anovulatory depending whether ovulation is present or not
• Anovulatory occurs when ovulation is not occurring and this type makes up about 90% of cases.
• An anovulatory menstrual cycle is common at early puberty and the period around menopause.
• In these cases, the period is delayed and when it occurs, menstruation can be very heavy and prolonged. This happens when women do not properly develop and release a matured egg, as a result, the corpus luteum that produces progesterone does not the form leading to a continuous production of estrogen which causes the overgrowth of the uterus lining.
• Anovulatory dysfunctional uterine bleeding is also sometimes due to a delay in the full maturation of the reproductive system in teenagers.
• About 1-2% of women with improperly treated anovulatory bleeding may develop endometrial cancer
• Ovulatory dysfunctional bleeding makes up about 10% of cases. This happens in women who are ovulating but have a prolonged progesterone secretion due to a low estrogen level causing an irregular shedding of the uterine lining.
CAUSES

• Infections of the uterus or cervix
• Thickening of the uterine wall or lining
