For some women, the monthly menstrual period is not only a biological process but also a difficult time accompanied by significant pain and discomfort. This condition, commonly called period pain, is medically known as dysmenorrhea.

What Is Dysmenorrhea?

Dysmenorrhea refers to cramp-like pain in the lower abdomen during menstruation. The pain may start as cramps in the lower abdomen and may spread to the lower back, groin and even the legs.

It is usually felt 1-2 days before menstruation begins and may continue more intensely during the first few days of bleeding. Severity varies between individuals; while some people experience mild discomfort, others may have pain that affects daily life, school or work performance and social activities.

Important Information: Mild menstrual cramps are common; however, pain that worsens each month, continues outside menstruation, causes pain during sexual intercourse or is accompanied by heavy bleeding or fever should be evaluated for an underlying cause.

When Should I See a Doctor for Dysmenorrhea?

A gynecology evaluation is recommended if period pain significantly affects daily life or appears later when it was not present before. Medical evaluation is important in the following situations:

  • Pain gets worse every month
  • Pain continues outside the menstrual period
  • Pain occurs during sexual intercourse
  • Pain is accompanied by nausea, vomiting, fever or heavy bleeding
  • Period pain interferes with school, work or social life
  • Pain relievers do not provide meaningful relief

You can contact us for evaluation if your period pain is getting worse each month, continues outside menstruation or affects your quality of life.

What Causes Dysmenorrhea?

The main mechanism is contraction of the uterus to shed menstrual blood. During these contractions, substances called prostaglandins are released. In people with higher prostaglandin levels, uterine contractions may be stronger and period pain may feel more intense.

Period pain without an underlying disease is called primary dysmenorrhea. It often begins at a younger age and is more prominent during the first days of menstrual bleeding. Pain that begins later, worsens over time or continues outside menstruation may suggest secondary dysmenorrhea.

Main Conditions That Can Cause Secondary Dysmenorrhea

Secondary dysmenorrhea means that period pain is related to an underlying gynecologic condition. The following conditions may cause secondary dysmenorrhea:

  • Endometriosis
  • Fibroids in or around the uterus
  • Intrauterine adhesions
  • Adenomyosis
  • Pelvic inflammatory disease
  • Intrauterine device or other uterine-ovarian conditions

For this reason, severe or changing menstrual pain should not be dismissed as “normal period pain.” Conditions such as endometriosis, fibroids or pelvic infection may need to be evaluated.

Does Dysmenorrhea Affect Fertility?

Primary dysmenorrhea usually does not affect fertility. However, conditions that may cause secondary dysmenorrhea, such as endometriosis, pelvic inflammatory disease, some fibroids or intrauterine adhesions, may affect fertility if left untreated.

Mild period pain may be common; however, if pain affects your quality of life, keeps you from social life or becomes more noticeable every month, it should not be considered simply “normal.” Health problems that may cause dysmenorrhea should not be overlooked.

Get Evaluated If Period Pain Affects Your Quality of Life

Pain severity, duration, pain outside menstruation, heavy bleeding, pain during intercourse and fertility plans should be evaluated together.
