More than 50 percent of women experience dysmenorrhea, also known as menstrual pain, for one or two days during menstruation. Menstrual cramps occur most often in teens; however, women in their twenties and older also suffer from painful periods. The American College of Obstetricians and Gynecologists (ACOG) states that about one in ten women experience menstrual pain so severely that they are unable to perform their normal routine for one to three days each month.

This can impact their lives in terms of their education or career because of missed days due to pain. 

What is Considered Menstrual Pain?

Many times menstrual cramps are described as a dull ache or a feeling of pressure in the lower abdomen. While the pain and intensity varies from woman to woman, dysmenorrhea is sometimes severe enough to cause nausea, vomiting, diarrhea and/or a general aches and pains. They can become so intense that you may be unable to walk or sit up, and instead need to lay down in order to minimize the pain. 

What Causes Menstrual Cramps?

Menstrual cramps are caused by the normal contraction of the uterus. Like all muscles, the uterus contracts and relaxes. Most of the time women are unaware of these contractions. During menstruation uterine contractions are much stronger and it is these strong contractions that are most likely to be painful.

Uterine contractions are caused by prostaglandins.

Prostaglandins are a natural substance made by the body; uterine prostaglandins cause uterine contractions. Strong uterine contractions cause the blood supply to the uterus to temporarily shutdown, depriving the uterine muscle of oxygen and setting up the cycle of menstrual contractions and pain.

When Should I Call a Doctor?

Typically, menstrual cramps will go away on their own and do not inhibit your daily functioning.

However, they sometimes do require medical attention. Below are signs and symptoms of when you may need a doctor:

  • You are unable to relieve menstrual pain with typical over-the-counter medications such as ibuprofen.
  • You experience pelvic pain that is not associated with menstruation.
  • You experience a fever, nausea, or vomiting with your pain.
  • You experience pelvic pain that is unusually severe or different in any way.

    Remember, your healthcare provider is there to help you. Most medical offices have nurses who are happy to evaluate whether you need to be seen in the office, and/or answer your questions over the phone.
