So anyone with a certain range of levels of Estrogen and Progesterone in their body, who experiences a sudden drop in those hormones, has cells capable of releasing enough Prostaglandins to cause painful contractions of abdominal smooth muscle tissue. The sensation is the same and the physiology is the same regardless of whether the smooth muscle tissue that’s contracting is that of a uterus or of other abdominal tissue.
The sudden decline in Estrogen and Progesterone is also the cause of the other unpleasant effects of Dysmenorrhea, including nausea and vomiting, diarrhea or constipation, headache, dizziness, disorientation, hypersensitivity to sound, light, smell and touch, fainting, and fatigue. So again, anyone who falls within a certain range of Estrogen and Progesterone levels, and experiences a sudden drop in those levels, is capable of experiencing all of these symptoms
I've always wondered about this .... and the actual timing of my reading this post is uncanny
