When a woman is going through pre-menstrual syndrome there are a lot of things going on in her body. Many women feel discomfort, bloating, tenderness in the abdomen and a host of other symptoms when that time of the month comes around. But one of the symptoms they may not realize is coming from their PMS is constipation. Believe it or not there are some women who have constipation as one of their PMS symptoms. These tend to be women who have higher levels of estrogen and are called estrogen dominant.
