Polycystic ovary syndrome (PCOS) is characterized by menstrual disorders, amenorrhea, infertility, obesity, acne, and hirsutism. The majority of patients with PCOS also exhibit high blood glucose and hyperinsulinemia. Therefore, it is crucial to pay attention to diet once these conditions occur. Foods high in fat and calories should be avoided as they can lead to weight gain and exacerbate the condition. Generally, it is advisable to consume a light diet, with plenty of vegetables and fruits, and to include beans and soy products. As patients with PCOS typically have high testosterone levels, consuming beans, which contain estrogen, can help replenish estrogen in the body and combat testosterone and other androgens. Thus, dietary considerations are essential for patients with PCOS.
