Some patients with polycystic ovary syndrome may recover ovarian function after daily running, but running should not be given too much importance and should be treated with other methods. Polycystic ovary syndrome is caused by endocrine disorder, a comprehensive disease caused by ovarian dysfunction, mostly accompanied by obesity and increased glucose tolerance. So its treatment, lifestyle adjustment is crucial. Some patients have the phenomenon of obesity, or even turn into type 2 diabetes due to long-term untreated, and need to control their weight, and aerobic exercise such as running is a better choice. In clinical practice, many patients have achieved recovery of ovarian function and successful pregnancy through weight control. For patients with more severe disease and fertility desire, they need to actively cooperate with doctors for ovulation promotion medication or surgery, and cannot focus their treatment on running. When reducing weight through running, patients with polycystic ovary syndrome should pay attention to protecting their joints and pay attention to the amount of exercise. At the same time, pay attention to a light diet and reasonable meals in order to achieve effective weight loss.
