Polycystic ovary syndrome (PCOS) is one of the important causes of female infertility, and it also has adverse effects on women's glucose/lipid metabolism, cardiovascular, endometrium and breast. In most people's impression, patients with polycystic ovary syndrome are "chubby", so will slim women not suffer from polycystic ovary syndrome? In fact, this is not the case.

Although obesity is not a diagnostic condition for polycystic ovary syndrome, it is indeed a common feature of patients with polycystic ovary syndrome, and 50%~70% of patients will be obese. Accordingly, there are also some patients who are not obese or even thin, and they are clinically called lean polycystic ovary syndrome. Lean polycystic ovary syndrome also has a negative impact on women's glucose/lipid metabolism and cardiovascular health.

Due to the lack of "obesity", many patients with lean polycystic ovary syndrome cannot be diagnosed in time. The good news is that compared with overweight or obese women with polycystic ovary syndrome, women with lean polycystic ovary syndrome have a higher success rate of infertility treatment and a relatively low risk of long-term complications. Even so, patients with lean polycystic ovary syndrome also need active treatment to reduce long-term health damage.

Obese polycystic ovary syndrome patients need to make lifestyle adjustment with weight loss as the goal, while for lean polycystic ovary syndrome patients, the goal of lifestyle intervention is to keep the weight within the normal range and prevent weight gain.

Patients should also carry out weight bearing training to increase muscle, reduce visceral fat, reduce androgen level, improve insulin resistance, and restore ovulation function. In daily life, patients should be as happy as possible, and at the same time, they should follow the doctor's advice to regulate treatment.
