It often starts with heavy flow, night sweats and increased problems with sleep and premenstrual symptoms. Making a diagnosis is hard and often women seek help for years before they have a clear diagnosis and effective treatment. CeMCOR believes that POI can be diagnosed while a woman still has regular cycles; you can assess if you notice any three new experiences out of the nine typical changes of Very Early Perimenopause http://www.cemcor.ubc.ca/resources/how-can-i-tell-i-am-perimenopause. If cycles have stopped for three or more months, then the diagnosis can be made by two elevated FSH levels taken in the first three days of flow a month apart.
POI used to be called “Early Menopause” or “Premature Ovarian Failure.”
