What are the causes of dysfunctional uterine bleeding in adolescents

Dysfunctional uterine bleeding is an irregular vaginal bleeding that occurs without a visible pelvic pathology, and in the absence of clear disease or pregnancy. Clinical manifestations of dysfunctional uterine bleeding reflect an abnormality in the cyclic estrogenic stimulation of the endometrial lining due to chronic estrogenic stimulation of the endometrial lining especially in girls with normogonadotropic anovulation. Common symptoms of dysfunctional uterine bleeding include irregular vaginal bleeding that lasts more than 7 days, irregular frequent periods that occur more often than every three weeks, and missed periods with absence of menstruation form 35 days to 45 days. Generally, vaginal bleeding lasts 4 to 6 days.
 
In most cases, DUB is associated with ovulatory dysfunction. About 90% of cases are anovulatory, whereas about ten percent of cases are ovulatory. AUB-O is the most common cause of AUB. In 50% of cases, it occurs most often in females older than 45 years of age 45, and in 20% of cases, it occurs in adolescents younger than 18. DUB is usually treated with a short course of high-dose combined oral contraceptives. If this treatment isn't effective, a dilation and curettage may be performed to scrap tissue from inside the uterus. When needed, volume replacement therapy NaCl 0.9% or a blood transfusion is used to quickly restore blood volume to normal.
