Premenstrual weight gain is only a short-term change. After ovulation, women's own estrogen secretion decreases and luteinizing hormone increases. In this way, the cells absorb more water and salt, which is the decline of fat metabolism rate, so women are prone to obesity during this time. Most people begin to lose weight or gain weight five days before the physiological period, which varies from person to person, about 500g to 3kg.

To lose weight during menstruation, we should pay attention to the fact that the amount of exercise should not be too large. You can play table tennis and basketball. Some strenuous exercises, such as high jump and 100-meter race, are best not to be carried out, so as not to cause excessive menstrual blood and uterine displacement.

In addition, menstrual period is not suitable for underwater sports, so don't take a cold bath to avoid irregular menstruation and infection. Keep a good mood during menstruation and let nervous nerves relax.
