If you have your period twice a month and the bleeding is light, you should be alert to the possibility that the bleeding is caused by pregnancy. If pregnancy is excluded, menstrual disorders due to endocrine disorders should be considered. Take care to relax, avoid overworking and staying up late, and stop smoking and drinking to prevent endocrine disorders from worsening. You also need to eat a light and hygienic diet, avoid eating greasy and indigestible food, control your weight and avoid obesity, because obesity can lead to endocrine disorders and aggravate your condition. During menstruation, try to avoid eating too much cold food, take more rest, exercise properly, enhance physical fitness, improve immunity, and strengthen the intake of nutrients to prevent malnutrition.
