Key takeaways

  • Period cramps are caused by higher levels of a hormone-like substance called prostaglandins that make the uterus contract during our period.
  • For many of us, period cramps are a side effect of our menstrual cycle, but for some individuals, the pain may be caused by an underlying condition.
  • Treatment options depend on the cause of period cramps and include anti-inflammatory pain medication (like ibuprofen), hormonal birth control, heat therapy, and exercise.

Period cramps happen when the uterus contracts as it sheds its lining. While periods may be a natural part of the menstrual cycle, we all have different experiences of period cramps. Many of us expect and plan for them, like the bleeding itself, but we rarely stop and think about why we even have pain during our periods in the first place. In this article, we dig into the details of what causes period cramps, tips to manage the pain, when to see a doctor, and common symptoms.
