Endometriosis living in children

Overview

Endometriosis is a condition where tissue similar to the lining of the womb grows outside the womb, such as on the ovaries, fallopian tubes, or the tissue lining the pelvis. In children and teenagers, it can cause pain and other symptoms even before their first period or during early adolescence.

While not as common as in adults, endometriosis does occur in children and adolescents. It may affect up to 1 in 10 girls and young women, though many cases go undiagnosed.

Endometriosis can affect anyone with a uterus, including girls and teenagers. It may start soon after the first period, but some children have symptoms even before menstruation begins.

Symptoms

Common symptoms

• Severe pelvic or abdominal pain that comes and goes
• Pain during periods that interferes with school or daily activities
• Pain during or after sex (if applicable)
• Pain with bowel movements or urination
• Heavy or irregular menstrual bleeding
• Chronic fatigue

Symptoms in children

• Pelvic or lower abdominal pain that is not relieved by over-the-counter pain relievers
• Pain that starts before the first period (pre-menarche)
• Pain that occurs monthly, even without a period
• Nausea, vomiting, or dizziness with periods
• Pain that causes missed school days or prevents participating in sports or hobbies

Symptoms in older adults

• This condition is less common in older adults because endometriosis usually improves after menopause. However, symptoms may include pelvic pain or discomfort if tissue remains.

Causes

Main causes

• The exact cause is not fully understood. One theory is that during menstruation, some menstrual tissue flows backward through the fallopian tubes into the pelvis and implants there.
• Another theory suggests that cells lining the pelvic organs may change into endometrial-like cells due to hormonal or immune system factors.

Risk factors

• Having a mother or sister with endometriosis
• Starting periods at an early age (before age 11)
• Having short menstrual cycles (less than 27 days)
• Having heavy or long periods

When to see a doctor

See a doctor urgently if:

• If your child has severe pelvic or abdominal pain that does not improve with rest or over-the-counter medicine.
• If pain is accompanied by fever, vomiting, or fainting.
• If there is heavy vaginal bleeding that soaks through a pad/tampon every hour.

Book a routine appointment if:

• If your child has period pain that regularly causes her to miss school or activities.
• If pain occurs between periods or with bowel movements.
• If you notice a pattern of monthly pain that is not relieved by usual painkillers.

Diagnosis

Doctors diagnose endometriosis by listening to your child's symptoms, doing a physical exam, and sometimes using imaging tests. The only way to confirm endometriosis is with a surgery called laparoscopy, where a doctor looks inside the pelvis with a small camera.

Tests that may be done

• Pelvic ultrasound: uses sound waves to create images of the pelvic organs (non-invasive, no radiation).
• MRI: magnetic resonance imaging gives detailed pictures of tissues.
• Laparoscopy: a minor surgery under anesthesia; the doctor makes a small cut in the belly and inserts a camera to see endometriosis tissue.

What to expect at your appointment

Your healthcare provider will ask about your child's pain, period history, and family history. They may also do a gentle abdominal exam. If endometriosis is suspected, they may refer you to a gynecologist who specializes in adolescent care. Getting a diagnosis can take time, but be patient and persistent.

Treatment

Treatment aims to reduce pain, improve quality of life, and slow the growth of endometrial tissue. The approach depends on age, symptoms, and whether your child wants to preserve fertility in the future.

Self-care at home

• Encourage gentle exercise like walking, yoga, or stretching to help ease pain and reduce stress.
• Apply heat (hot water bottle or heating pad) to the lower belly during pain.
• Help your child practice relaxation techniques such as deep breathing or meditation.
• Ensure your child gets enough sleep and stays hydrated.
• Track symptoms using a diary to identify patterns and triggers.

Medical treatments

Doctors may suggest hormone therapy, such as birth control pills or other hormonal medications, to help control the menstrual cycle and reduce pain. They may also recommend non-hormonal pain relievers. Always talk to your doctor about the options that are best for your child’s age and health. Never give your child any medicine without checking with a healthcare provider.

When is surgery considered?

If pain is severe and does not improve with medicine, a doctor may recommend laparoscopy to remove endometrial tissue. This is a minor surgery but involves general anesthesia. It is not always a permanent solution, but it can provide relief for months to years.

Living with this condition

Living with endometriosis as a child can be challenging, but many young people manage well with the right support. Develop a routine that includes school, rest, and activities. Communicate with teachers about your child's needs so they can help during pain flare-ups.

Lifestyle tips

• Help your child stay active with low-impact sports like swimming or cycling.
• Encourage a regular sleep schedule – fatigue can make pain worse.
• Teach your child to listen to their body and take breaks when needed.
• Work with the school nurse to have a plan for managing pain during school hours.

Diet and exercise

There is no one diet that works for everyone, but some children find that eating more fruits, vegetables, whole grains, and healthy fats (like those in fish and nuts) helps reduce inflammation. Avoid processed foods and too much sugar. Gentle exercise, such as walking or stretching, can improve blood flow and reduce stress.

Mental health and emotional wellbeing

Having ongoing pain can make your child feel sad, anxious, or frustrated. It is normal to have these feelings. Let your child know it is okay to talk about emotions. If you notice signs of depression – such as withdrawing from friends, not enjoying favorite activities, or changes in sleep/eating – speak to a mental health professional or your doctor.

Prevention

There is no known way to prevent endometriosis. However, early recognition and treatment can prevent symptoms from becoming severe and help your child maintain a good quality of life.

Complications

If left untreated

• Chronic pelvic pain that continues into adulthood
• Possible fertility problems later in life
• Increased risk of anxiety or depression from living with pain
• Missed school and social activities, affecting development

Long-term outlook

With the right care – including medical treatment, lifestyle changes, and support – most children with endometriosis can manage their symptoms and lead full, active lives. Many find that symptoms improve after their teenage years or with hormone therapy. Researchers continue to work on better treatments and understanding of this condition.
