Dysmenorrhea & Painful Periods

Dysmenorrhea is the medical term for menstrual cramps also known as painful periods, which are caused by uterine contractions. Primary dysmenorrhea refers to common menstrual cramps, while secondary dysmenorrhea results from a disorder in the reproductive organs. Both types can be treated.

Dysmenorrhea: Painful PeriodsDysmenorrhea and Painful Periods

What is dysmenorrhea?
Pain associated with menstruation is called dysmenorrhea.

How common is dysmenorrhea?
Dysmenorrhea is the most commonly reported menstrual disorder. More than one-half of women who menstruate have some pain for 1–2 days each month.

What are the types of dysmenorrhea?
There are two types of dysmenorrhea: primary dysmenorrhea and secondary dysmenorrhea.

What is primary dysmenorrhea?

Primary dysmenorrhea is pain that comes from having a menstrual period, or “menstrual cramps.”

Dysmenorrhea is the medical term for pain with menstruation. There are two types of dysmenorrhea: “primary” and “secondary”.

Primary dysmenorrhea is common menstrual cramps that are recurrent (come back) and are not due to other diseases. Pain usually begins 1 or 2 days before, or when menstrual bleeding starts, and is felt in the lower abdomen, back, or thighs. Pain can range from mild to severe, can typically last 12 to 72 hours, and can be accompanied by nausea-and-vomiting, fatigue, and even diarrhea. Common menstrual cramps usually become less painful as a woman ages and may stop entirely if the woman has a baby.

Secondary dysmenorrhea is pain that is caused by a disorder in the woman’s reproductive organs, such as endometriosis, adenomyosis, uterine fibroids, or infection. Pain from secondary dysmenorrhea usually begins earlier in the menstrual cycle and lasts longer than common menstrual cramps. The pain is not typically accompanied by nausea, vomiting, fatigue, or diarrhea.

What causes primary dysmenorrhea?

Primary dysmenorrhea usually is caused by natural chemicals called prostaglandins. Prostaglandins are made in the lining of the uterus.

Menstrual cramps are caused by contractions (tightening) in the uterus (which is a muscle) by a chemical called prostaglandin. The uterus, where a baby grows, contracts throughout a woman’s menstrual cycle. During menstruation, the uterus contracts more strongly. If the uterus contracts too strongly, it can press against nearby blood vessels, cutting off the supply of oxygen to the muscle tissue of the uterus. Pain results when part of the muscle briefly loses its supply of oxygen.

When does the pain associated with primary dysmenorrhea occur during the menstrual period?

Pain usually occurs right before menstruation starts, as the level of prostaglandins increases in the lining of the uterus. On the first day of the menstrual period, the levels are high. As menstruation continues and the lining of the uterus is shed, the levels decrease. Pain usually decreases as the levels of prostaglandins decrease.

At what age does primary dysmenorrhea start?Dysmenorrhea

Often, primary dysmenorrhea begins soon after a girl starts having menstrual periods. In many women with primary dysmenorrhea, menstruation becomes less painful as they get older. This kind of dysmenorrhea also may improve after giving birth.

What is secondary dysmenorrhea?

Secondary dysmenorrhea is caused by a disorder in the reproductive system. It may begin later in life than primary dysmenorrhea. The pain tends to get worse, rather than better, over time.

When does the pain associated with secondary dysmenorrhea occur during the menstrual period?

The pain of secondary dysmenorrhea often lasts longer than normal menstrual cramps. For instance, it may begin a few days before a menstrual period starts. The pain may get worse as the menstrual period continues and may not go away after it ends.

How does secondary dysmenorrhea cause menstrual cramps?

Menstrual pain from secondary dysmenorrhea is caused by a disease in the woman’s reproductive organs. Conditions that can cause secondary dysmenorrhea include:

  • Endometriosis – A condition in which the tissue lining the uterus (the endometrium) is found outside of the uterus.
  • Adenomyosis – A condition where the lining of the uterus grows into the muscle of the uterus.
  • Pelvic inflammatory disease – An infection caused by bacteria that starts in the uterus and can spread to other reproductive organs.
  • Cervical stenosis – Narrowing of the opening to the uterus.
  • Fibroids (benign tumors) – Growths on the inner wall of the uterus.

What disorders can cause secondary dysmenorrhea?

Some of the conditions that can cause secondary dysmenorrhea include the following:

  • Endometriosis – In this condition, tissue from the lining of the uterus is found outside the uterus, such as in the ovaries and fallopian tubes, behind the uterus, and on the bladder (see the FAQ Endometriosis). Like the lining of the uterus, endometriosis tissue breaks down and bleeds in response to changes in hormones. This bleeding can cause pain, especially right around menstruation. Scar tissue called adhesions may form inside the pelvis where the bleeding occurs. Adhesions can cause organs to stick together, resulting in pain.
  • Adenomyosis – Tissue that normally lines the uterus begins to grow in the muscle wall of the uterus.
  • Fibroids – Fibroids are growths that form on the outside, on the inside, or in the walls of the uterus (see the FAQ Uterine Fibroids). Fibroids located in the wall of the uterus can cause pain.

What tests are done to find the cause of dysmenorrhea?

If you have dysmenorrhea, your health care provider will review your medical history, including your symptoms and menstrual cycles. He or she also will do a pelvic exam.
An ultrasound exam may be done. In some cases, your health care provider will do a laparoscopy. This is a type of surgery that lets your health care provider look inside the pelvic region.

How can I know if the dysmenorrhea (pain of menstrual cramps) I’m having is normal?

If you have severe or unusual menstrual cramps or cramps that last for more than 2 or 3 days, contact your healthcare provider. Both primary and secondary menstrual cramps can be treated, so it’s important to get checked.

First, you will be asked to describe your symptoms and menstrual cycles. Your healthcare provider will also perform a pelvic exam. During this exam, your doctor inserts a speculum (an instrument that lets the clinician see inside the vagina) and examines your vagina, cervix, and uterus. The doctor will feel for any lumps or changes, and a small sample of vaginal fluid may be taken for testing.

If secondary dysmenorrhea is suspected, further tests may be needed. If a medical problem is found, your healthcare provider will discuss treatments.

If you use tampons and develop the following symptoms, get medical help right away:

  • Fever over 102 degrees Fahrenheit
  • Vomiting
  • Diarrhea
  • Dizziness, fainting, or near fainting
  • A rash that looks like a sunburn

These are symptoms of toxic shock syndrome, a life-threatening illness.

How is dysmenorrhea treated?

Your health care provider may recommend medications to see if the pain can be relieved. Pain relievers or hormonal medications, such as birth control pills, often are prescribed. Some lifestyle changes also may help, such as exercise, getting enough sleep, and relaxation techniques.
If medications do not relieve pain, treatment will focus on finding and removing the cause of your dysmenorrhea. You may need surgery. In some cases, a mix of treatments works best.

What medications are used to treat dysmenorrhea?

Certain pain relievers, called nonsteroidal anti-inflammatory drugs (NSAIDs), target prostaglandins. They reduce the number of prostaglandins made by the body and lessen their effects. These actions make menstrual cramps less severe.
NSAIDs work best if taken at the first sign of your menstrual period or pain. You usually take them for only 1 or 2 days. Women with bleeding disorders, asthma, aspirin allergy, liver damage, stomach disorders, or ulcers should not take NSAIDs.

What types of birth control methods help control dysmenorrhea?

Birth control methods that contain estrogen and progestin, such as the pill, the patch, and the vaginal ring, can be used to treat dysmenorrhea. Birth control methods that contain progestin only, such as the birth control implant and the injection, also may be effective in reducing dysmenorrhea.

The hormonal intrauterine device or IUD can be used to treat dysmenorrhea as well.

What types of medication can be used to treat dysmenorrhea caused by endometriosis?

If your symptoms or a laparoscopy point to endometriosis as the cause of your dysmenorrhea, birth control pills, the birth control implant, the injection, or the hormonal intrauterine device can be tried. Gonadotropin-releasing hormone agonists are another type of medication that may relieve endometriosis pain. These drugs may cause side effects, including bone loss, hot flashes, and vaginal dryness. They usually are given for a limited amount of time. They are not recommended for teenagers except in severe cases when other treatments have not worked.

What alternative treatments help ease dysmenorrhea? dysmenorrhea

Certain alternative treatments may help ease not enough research has been done to recommend dysmenorrhea. them as effective Vitamin treatments B or magnesium supplements may be helpful, but for dysmenorrhea. Acupuncture has been shown to be somewhat helpful in relieving dysmenorrhea.

When is uterine artery embolization (UAE) done to treat dysmenorrhea?
If fibroids are causing your dysmenorrhea, a treatment called uterine artery embolization (UAE) may help.

What is done during UAE?
In this procedure, the blood vessels to the uterus are blocked with small particles, stopping the blood flow that allows fibroids to grow. Some women can have UAE as an outpatient procedure.

What complications are associated with UAE?
Complications include infection, pain, and bleeding.

When is surgery done to treat dysmenorrhea?
If other treatments do not work in relieving dysmenorrhea, surgery may be needed. The type of surgery depends on the cause of your pain.
If fibroids are causing the pain, sometimes they can be removed with surgery. Endometriosis tissue can be removed during surgery. Endometriosis tissue may return after the surgery, but removing it can reduce the pain in the short term. Taking hormonal birth control or other medications after surgery may delay or prevent the return of pain.

Hysterectomy may be done if other treatments have not worked and if the disease-causing the dysmenorrhea is severe. This procedure normally is the last resort.
