Menopausal women who do hyperbaric oxygen will not be able to regain menstruation because the ovarian function has already declined at this time. The main reason why women go through menopause is because the ovary function declines after a certain age and the level of estrogen in the body is relatively low. Hyperbaric oxygen therapy does not improve the function of the ovaries, so it cannot restore menstruation. If menopausal women want to resume menstruation, they may need to use medication under the guidance of a doctor, usually taking artificial cycles, that is, taking estradiol valerate and progesterone. If you are taking estrogen and progesterone artificial cycle to regulate menstruation, you need to rule out the contraindications to the use of drugs, such as women with uterine fibroids, breast tumors, epilepsy, thrombotic diseases, etc., is not suitable for the artificial cycle of treatment.
