During menstruation, the increase in interstitial fluid will cause edema in the whole body, and the weight will increase by 0.5-1 kg. At this time, you can drink a lot of boiled water to accelerate the body’s metabolism to avoid the occurrence of persistent edema, and pay attention to your diet, eat less spicy and stimulating food, including cold food, and eat more vegetables and fruits, so that you can achieve balanced nutrition and avoid the occurrence of persistent edema. This situation does not last long and will return to normal 2-3 days after the end of menstruation and will not affect the health of the body. It is also important to pay attention to vulva hygiene to avoid vaginal inflammation due to lack of hygiene, and to avoid localized hyperplastic particles due to menstrual blood contamination.
