JACKSONVILLE, Fla. -- Canadian researchers have uncovered a potentially new explanation as to why women are moody during that time of the month, but it remains to be seen whether the scientists will be able to convince women it's true.
In short, the researchers say PMS is BS.
According to a published report, researchers at the University of Toronto say mood changes might not be tied to menstrual cycles as previously thought. What they're tied to, scientists don't know.
They looked at 47 studies related to PMS and concluded none of them showed clear evidence linking mood swings with PMS. However, bloating and abdominal pain were found to be linked to the menstrual cycle.
The study is published in Gender Medicine
