How will I know if I am menopausal after hysterectomy with conservation of the ovaries?

Generally hot flushes are the number one symptom of menopause and are usually a fair indicator of menopausal status. The average age for menopause in Australia is 51.  Clearly following hysterectomy your periods will cease so this is not a sign you can rely on to signal menopause as it would be without hysterectomy. If there is doubt about whether you are menopausal a simple blood test is all that is required to confirm this after hysterectomy.
