It is a normal situation to have a bloated stomach during the onset of menstruation: in the first case, due to the decrease of estrogen level and progesterone level in women’s body during menstruation, it will lead to abdominal bloating and indigestion, so women show a bloated stomach. The second situation is that a small number of women will experience lower abdominal pain such as dysmenorrhea during menstruation, so women may exhibit a bloated stomach. In the event of bloating, women should pay attention to proper rest, eat more easily digestible food, and walk appropriately to help relieve bloating, which will be relieved and disappear after the menstrual period. In addition, women should not be overly stressed during this period, and must pay attention to avoid the stimulation of adverse factors during the menstrual period, so as not to lead to menstrual disorders.
