Pulmonary surfactant, secreted via exocytosis of lamellar bodies (LB) by alveolar type II (AT II) cells, maintains low alveolar surface tension and is therefore essential for normal lung function.
This in turn causes abnormalities in the levels of the other hormones, Estrogen and Progesterone, thus adding to the chemical turmoil in the body. The common causes of Anovulatory Cycles include: Polycystic Ovarian Disease (PCOD). Hyperprolactinaemia (increased blood levels of the hormone Prolactin).
Anovulatory DUB is the most common cause of abnormal uterine bleeding. Test for treatable causes of bleeding; tests may include a pregnancy test, CBC, measurement of hormone levels (TSH, prolactin, progesterone), and often ultrasonography and endometrial sampling.
