Levonorgestrel IUD

Chronic abnormal uterine bleeding is bleeding from the uterine endometrium that is abnormal in volume, regularity, or timing for most of the past 6 months.

Anovulatory bleeding is the most common cause of noncyclic menstrual blood flow that may range in volume from spotty to excessive. It is attributed to anovulatory sex steroid production.

Medical treatment is the best management for anovulatory bleeding.

Estrogen-containing contraceptives, eg.Combined oral contraceptives, are contraindicated in women with a history of uncontrolled hypertension. They are considered to be UKMEC category 4.

Levonorgestrel IUD and the copper IUD are both UKMEC Category 1 for uncontrolled hypertension. However, on the levonorgestel IUD would be effective for this patients irregular bleeding and anemia.

On a different note, PCOS patients are found to be 3 times as likely as the general population to develop endometrial cancer. Conservative management via levonorgestrel IUD in cases of precancerous and early well differentiated endometrial neoplasia has displayed viability in patients concerned with preserving their fertility. (Keeping in mind Rotterdam Criteria for PCOS diagnosis.)
