In my first post I mentioned that I vomit and have diarrhea the 1st day of every period, along with horrible menstrual cramps. This has gone on for about 13 years. I have ask several Doctors and half have suggested I am lying and the other half say they have never heard of this happening. I have always been curious as to why.
It is the prostaglandins. Prostaglandins are strong smooth muscle contractors causing the menstrual cramps, vomiting and diarrhea.
Prostaglandin inhibitors are frequently used by women to relieve menstrual cramps. But these drugs are very dangerous. Better choices for preventing the smooth muscle contractions include magnesium malate or herbs such as cramp bark or silk tassel.
