Polycystic ovarian syndrome(PCOS)is a heterogeneous disease related to female endocrine and reproductive disorders,and it is the main cause of secondary amenorrhea,irregular menstrual cycles,and anovulatory infertility in women of childbearing age.Clinical manifestations include oligomenorrhea,hirsutism,acne,obesity,and infertility.In recent years,with the development of the social economy and the change of natural environment,the number of obese pa-tients with PCOS gradually increased,and the psychological and physiological pressure faced by women of childbearing age also increased.These pressures have seriously impacted their physical and mental health and quality of life.Obesity not only has physiological effects on patients with PCOS,but also increases their psychological burden,causing negative emotions such as depression,anxiety,irritability,low self-esteem,and depression.Studies have shown that obese pa-tients with PCOS not only faced the problems of weight gain and weight loss,but also more likely to have emotional prob-lems such as anxiety,irritability,and depression.Compared with women without PCOS,women with PCOS have more serious psychological problems,weaker self-esteem,and more negative body image.Endocrine and metabolic disorders of obese patients with PCOS are more serious than those of ordinary people.At the same time,the probability of poor effica-cy in treating patients with infertility increases,which may increase the risk of pregnancy complications in pregnant women.This paper discusses the prevention strategies of obese patients with PCOS by consulting the resent literature and combining with the theory of"adjustable constitution"in traditional Chinese medicine.The aim is to provide new ideas for the prevention and treatment of obese patients with PCOS.
