Why Endometriosis Makes Periods So Painful - What is Dysmenorrhea?


What is dysmenorrhea?

Dysmenorrhea is the scientific term used to describe painful periods.

There are two types of dysmenorrhea [1]: primary dysmenorrhea and secondary dysmenorrhea. The former refers to period pain without an underlying medical condition. Secondary dysmenorrhea is caused by a disease or medical condition. Secondary dysmenorrhea is one of the main symptoms of endometriosis and can be accompanied with painful ovulation. Women often describe the pain they experience as “killer cramps” during their periods.

How can dysmenorrhea affect patients’ quality of life?

The symptoms of endometriosis can impact just about every aspect of a patients' life from career to relationships to finances. In a 2017 study on endometriosis patients’ quality of life, researchers found that painful periods, irregular periods and general abdominal pain all significantly correlated with negative results on an endometriosis health profile questionnaire. It included five categories ranging from pain, control and powerlessness, emotional well-being, social support, and self-image.


The process of primary dysmenorrhea

Period pain is caused by an excess or imbalance in prostaglandin secretion from the lining of the uterus during periods [3]. Prostaglandins are hormones that control inflammation, blood flow, and the formation of blood clots [4].

Why and how endometriosis causes dysmenorrhea

In women with endometriosis, the levels of prostaglandins are even higher in the menstrual blood than that of women without the disease [5]. This could explain why women with endometriosis experience periods with extreme pain. Also, research has shown that the frequency, magnitude, and basal pressure tone of uterine contractions are higher in women with endometriosis compared to those without the disease [6]. As a result, the severe period pain experienced by women with endometriosis could also be the result of abnormal contractions of the uterus.


Symptoms of dysmenorrhea may include aching pelvic pain, abdominal pressure, and pain in the hips, lower back, and inner thighs [1].

How women with endometriosis describe the pain they experience during their periods

Many women experience pain during their periods, but those with endometriosis describe their menstrual pain to be so incapacitating, it prohibits performing even the simplest of tasks. Women with the disease also tend to have their period pain worsen over time [7]. Some women with endometriosis describe their period pain as “throbbing, gnawing, and dragging,” or “like their insides are being pulled down” [8].

Other symptoms that often accompany painful periods in women with endometriosis

In addition to extreme pain during menstruation, women with endometriosis often experience other symptoms including:

  • Painful ovulation

  • Painful bowel movements

  • Constipation with periods

  • Diarrhea with periods

  • Gas and bloating with periods

  • Shooting leg pains with periods


Are painful periods a sure sign of endometriosis?

Painful periods are not always a sure sign of endometriosis. Also, the absence of painful periods does not guarantee one does not have endometriosis. In addition to painful periods, endometriosis is often accompanied by a number of other symptoms. These include gastrointestinal abnormalities, such as diarrhea, constipation, and/or painful bowel movements, pain during intercourse, and neuropathy [9].

Other causes of painful periods

Secondary dysmenorrhea could be caused by a number of other underlying conditions [1]. These could include:

  • Adenomyosis, otherwise known as endometriosis of the uterus; a condition where the endometrial tissue that lines the uterus, grows into the uterine muscle wall [10]

  • Uterine fibroids, or benign tumors that grow from the muscle layers of the uterus [11]

  • Cervical stenosis or the narrowing of the opening of the cervix

  • Infections


OTC painkillers

The most common way to manage the pain of both primary and secondary dysmenorrhea are non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and aspirin. They work by reducing the menstrual flow, therefore, decreasing the pressure inside the uterus. They also reduce the levels of prostaglandins released during menstruation [12].

Hormonal contraceptives

A popular way to manage dysmenorrhea caused by endometriosis are combined oral contraceptives. They work by suppressing ovulation and inhibiting the growth of the endometrial implants and may reduce menstrual pain associated with endometriosis.

Other ways of reducing the pain


  • Applying topical heat

  • Exercising

  • Avoiding the consumption of caffeine, alcohol, and tobacco

Treating endometriosis-related dysmenorrhea

The gold standard for the treatment of endometriosis is laparoscopic deep excision surgery [14]. During the surgery, the surgeon makes small incisions in the abdomen of the patient and introduces an instrument known as a laparoscope, which allows them to visualize the inside of the abdomen. They then remove the endometrial lesions using sharp dissection. Patients often report a decrease in symptoms, while others say their symptoms completely disappear. However, women should remember that there is a small risk of endometriosis recurring even after the best of surgeries.


Painful period

My pain started at a very young age, during my adolescent years. I remember dreading gym class because any physical activity on the days of my menstrual cycle would cause me to vomit due to the severity of my pelvic pain.

I remember my prom, an exciting time for me and my friends, getting dressed up, make-up and all, but all I can recall is getting my period, and being in so much pain that I cried the entire time I was getting ready. Fast forward to my honeymoon: period again, and my first few days as Mrs. Flores became days I just wanted to sleep and not feel the pain.

    Like so many women who have tirelessly sought a correct diagnosis and proper, thorough medical treatment for endometriosis, I found myself 26 years into this unwanted journey without clear answers or help from four previous gynecological doctors and two emergency laparoscopic surgeries.
