It is certainly beneficial for the disease itself when polycystic weight loss is achieved, but some polycystic patients can heal themselves without special treatment. Polycystic and polycystic ovary syndrome are two different concepts and should not be confused. If polycystic refers to polycystic ovaries, it generally refers to a morphological change in the ovaries that is suggested by ultrasound, mostly asymptomatic or not accompanied by sex hormone abnormalities, but only ultrasound suggests polycystic changes in the ovaries on both sides, which can usually lead to natural conception. If polycystic means polycystic ovary syndrome, it is often accompanied by scanty menstruation, non-ovulation, obesity, hirsutism, hormonal tests (e.g. luteinizing hormone to follicle stimulating hormone ratio imbalance, high androgens), which often affects pregnancy and usually requires ovulation resumption or ovulation promotion to conceive. So if it is only polycystic, with regular menstruation and no manifestation of hyperandrogenemia, it will not affect me much. However, in the case of polycystic ovary syndrome, especially in those with obesity, weight control and weight loss are beneficial to menstruation, and some even do not need to take medication to treat this disease. In conclusion, obesity can have an effect on women’s menstruation or pregnancy. If weight control through, for example, more exercise rather than dieting is advocated, weight loss is effective for the treatment of polycystic ovary syndrome.
