Menstrual cramps are severe, painful cramps that occur during a period. There are two types:

• Primary. This type starts soon after the first menstrual period. It's usually lifelong. But it may get better over time.
• Secondary. This type is caused by another health problem, such as a growth or infection. It usually starts later.

Most cramps are caused by abnormal tightening of the muscles of the uterus (contractions). This is from changing hormone levels. The hormone prostaglandin controls the contractions of the uterus.

Secondary menstrual cramps can be caused by endometriosis. This is when tissue that forms the inside lining of the uterus also grows outside the uterus. It can grow on other organs inside the pelvis or belly (abdomen). This can also cause internal bleeding, infection, and pelvic pain.

Other causes of secondary menstrual cramps can include:

• Infection of the reproductive organs (pelvic inflammatory disease).
• Fibroids (noncancer [benign] growths in the uterus).
• A fertilized egg that implants outside the uterus (ectopic pregnancy).
• Pregnancy loss (miscarriage).
• Other infection in the pelvis.
• Growths in the pelvis such as tumors or polyps.

A teen is more at risk for menstrual cramps if they have:

• Their first period at an early age.
• Long or heavy periods.
• A family history of menstrual cramps.

Smoking also increases the risk.

Symptoms can occur a bit differently in each teen. The most common symptoms include:

• Cramping and pain in the lower abdomen.
• Low back pain.
• Pain spreading down the legs.

Other symptoms can include:

• Nausea.
• Vomiting.
• Diarrhea.
• Tiredness.
• Weakness.
• Fainting.
• Headaches.

Symptoms occur just before menstrual bleeding starts each month. The pain can last for 1 to 2 days or more. It then lessens at the end of the period.

Symptoms of secondary menstrual cramps can start several days before menstrual bleeding starts. The pain may get worse and last for days, weeks, or longer.

Menstrual symptoms can be like other health conditions. Make sure your teen sees their doctor for a diagnosis.

The doctor will ask about your child's symptoms and health history. They may also ask about your family's health history. The doctor will give your teen a physical exam. The physical exam may include a pelvic exam. Your child may also have tests, such as:

• Ultrasound. This painless test uses sound waves and a computer to create images of blood vessels, tissues, and organs. Ultrasounds are used to view internal organs such as the uterus and ovaries. They also assess blood flow through various vessels.
• Laparoscopy. This procedure uses a thin tube with a lens and a light (laparoscope). The scope is inserted into a small cut (incision) in the abdominal wall. The doctor can see abnormal growths in the pelvis and abdomen.
• Hysteroscopy. This is an exam of the cervix and inside of the uterus. It's done with a viewing tool (hysteroscope) inserted through the vagina.

Treatment will depend on your teen's symptoms, age, and general health. It will also depend on how severe the condition is. Treatment options include:

• Pain medicines that block prostaglandins, such as ibuprofen.
• Acetaminophen.
• Birth control pills (oral contraceptives).
• An IUD with progesterone.
• Eating healthy foods.
• Getting enough sleep.
• Regular exercise.
• Using a heating pad across the lower abdomen.
• A hot bath or shower.
• Transcutaneous electrical nerve stimulation (TENS).
• Surgery.
• Acupuncture.
• Abdominal massage.
• Relaxation methods.

Talk with your teen's doctor about the risks, benefits, and possible side effects of all treatments.

Possible complications include missed school or work because of severe pain. Menstrual cramps can be caused by a condition such as endometriosis. If left untreated, this may have an impact on your teen's future ability to get pregnant.

Painful periods can be difficult to cope with every month. You can help by making sure your teen has the tools to treat pain symptoms quickly. Your teen may also need emotional support during painful days.

• Know the reason for the visit and what you want to happen.
• Before your visit, write down questions you want answered.
• At the visit, write down the name of a new diagnosis and any new medicines, treatments, or tests. Also write down any new instructions your doctor gives you for your child.
• Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are and when they should be reported.
• Ask if your child's condition can be treated in other ways.
• Know why a test or procedure is recommended and what the results could mean.
• Know what to expect if your child does not take the medicine or have the test or procedure.
• If your child has a follow-up appointment, write down the date, time, and purpose for that visit.
• Know how you can contact your child's doctor after office hours, and on weekends and holidays. This is important if your child becomes ill and you have questions or need advice.
