Hormonal imbalance is a loose term used to describe the disorders of ovulation caused by abnormal levels of any of the various hormones that is responsible for regulating ovulation and in turn the menstrual cycle. Although often used to refer almost exclusively to PCOS since it accounts for most of the cases of ovulation disorders, other various hormonal abnormalities may disrupt the normal menstrual cycle and hinder ovulation; they include, hyperprolactinaemia, congentital adrenal hyperplasia, thyroid disorders, cushing syndrome and androgen secreting tumors among many others. Because these hormones in abnormal levels interfere with ovulation, yes they may cause irregular menses among many other complications such as infertility, miscarriages, obesity and hirsutism. Treatment often involves identification of the cause of the abnormal hormones and treating it whenever possible. Hormone replacement may be required when abnormally low levels of a particular hormone is responsible for the ovulation disorder while suppression of excessive secretion of some hormones may be necessary when their abnormally high levels are responsible for the disorder.
