Swollen feet during menstruation means that there is a lot of fluid in the body, due to water and sodium retention in the body. The hormonal changes in the body during menstruation are physiological regulation, not a pathological state, so it is normal to have swollen feet during menstruation. But to what extent is it normal to have swollen feet, i.e. one feels a slight suffocation of the feet, this is normal. If the feet are swollen and the swelling above the ankle is severe, as well as the calf is also swollen, this should not happen. So pay attention to the regulation during the menstrual period, too much salt can also happen to increase the amount of circulating blood in the body, so it is necessary to have a low salt diet. Also pay attention to rest, overexertion can also affect the excretion of body fluids. So it is normal to have swollen feet during menstruation, but note that the swollen feet should not be too serious, just a slight bit of suffocation in the ankle, which is normal.
