Usually, low estrogen takes 1-6 months to regulate. The recovery time for low estrogen is related to the cause of low estrogen and there are large individual differences. Low estrogen is an endocrine disorder, mostly seen in patients with ovarian hypofunction, and can cause women to have fewer menstrual periods, shorter menstrual cycles, and even infertility. Due to the different sensitivity of each individual to medication, some patients may be able to adjust their estrogen in about 1-6 months with medication, such as oral supplementation of Glaxo. However, in some cases, after a longer period of time, the estrogen cannot be restored to normal, so it is necessary to visit the endocrinology department of a hospital in time to change the treatment plan according to medical advice. In addition, patients with low estrogen levels can eat more phytoestrogen-rich foods, such as soy, millet, black beans, royal jelly, Colla Corii Asini, and deer fetus cream, etc., and pay attention to rest, ensure sleep, exercise properly, avoid mood swings, and maintain a happy mood to promote estrogen recovery as soon as possible.
