It depends on the ovaries are removed and what age the surgery has been done. If it has been done in younger age, the hysterectomy along with the ovaries they will have severe menopausal symptoms like osteoporosis, hot flushes and myocardial infarction. So it is best to start the hormonal replacement immediately after the surgery but if the ovaries are retained they will have some hormones retained so they will not require hormones replacement quickly. But at the later stage if they have any symptoms. If it is done at a later stage with the ovaries are removed depending on the symptoms we can start but empirically also people starts on the HRT therapy to prevent future myocardial infarction.
