Period cramps are caused by the uterus contracting due to substances called prostaglandins, leading to pain and discomfort during menstruation.
Period cramps, also known as dysmenorrhea, occur because of the natural process where the uterus contracts to help shed its lining. These contractions are triggered by chemicals in the body called prostaglandins. When the level of prostaglandins is high, the uterus contracts more strongly, which can cut off blood supply to the tissue of the uterus, causing pain.
Understanding these processes helps explain why period cramps occur and why they can vary in intensity. Managing these cramps often involves addressing the levels of prostaglandins and improving blood flow to the uterus.
We would love to help them too.
