Polycystic, or polycystic ovary syndrome, patients with polycystic ovary syndrome can drink milk. Milk is rich in protein, fat, vitamins and calcium, iron, phosphorus and other nutrients, but also can provide energy for the body. Patients with polycystic ovary syndrome can drink milk in moderation to replenish the nutrients needed by the body and maintain normal physiological functions. If polycystic ovary syndrome patients are combined with overweight or obesity, they should control the total calorie intake in their diet, increase the intake of fresh vegetables and fruits appropriately, and at the same time adhere to appropriate physical exercise to control body weight and reduce insulin resistance. It should be noted that people who are lactose intolerant should not drink milk, so as not to cause diarrhea, bloating, abdominal pain and other discomforts. In addition, people who are allergic to dairy products should not drink milk, otherwise they are prone to allergic symptoms.
