Question: What Causes Menstrual Cramps?
Answer: Prostaglandin is a hormone, produced by the uterus, which causes uterine contractions. The medical community believes that high levels of prostaglandin may contribute to menstrual cramps, as well as to dysmenorrhea. Premenstrual syndrome (PMS), stress, and anxiety may also contribute to menstrual cramps.
