Endometriosis living in teenagers
Informed by recognized medical guidance
Overview
Endometriosis (en-doh-mee-tree-OH-sis) is a condition where tissue similar to the lining of the womb grows in other places, like the ovaries or fallopian tubes. This tissue can cause pain, especially during periods, and can affect a teenager's daily life.
Key facts
- Endometriosis is not an infection and is not contagious.
- It can cause very painful periods, but some people have no symptoms.
- It can be managed with the right care and support.
Endometriosis is more common than many people think. It affects about 1 in 10 women and girls of reproductive age, including teenagers.
Endometriosis can affect any teenager who has started their periods, but it most often appears in the teenage years and early adulthood.
Symptoms
- Sudden, severe pelvic pain that does not go away
- Fainting or feeling very dizzy with pelvic pain
- Signs of heavy bleeding (soaking through a pad or tampon in less than an hour)
- ⚠Pain that does not get better with over-the-counter pain relief (like ibuprofen or paracetamol)
- ⚠Fever along with pelvic pain (possible infection)
- ⚠New or worsening symptoms that worry you
Common symptoms
- Very painful periods that make it hard to do normal activities
- Pain in the lower belly or back that may come and go
- Pain during or after sex (in older teenagers)
- Heavy or irregular periods
- Feeling very tired or low on energy
- Nausea, bloating, or diarrhoea during periods
Symptoms in children
- Endometriosis is rare before periods start, but if it does occur, symptoms may include belly pain and bloating that gets worse with time.
Symptoms in older adults
- Endometriosis often improves after menopause, but some women may still have pain or other symptoms.
Causes
Main causes
- The exact cause is not known, but endometriosis happens when cells from the womb lining grow elsewhere in the body.
- It may be linked to the immune system or genetics (runs in families).
Risk factors
- Having a close family member (mother, sister) with endometriosis
- Starting periods early (before age 11)
- Having short monthly cycles (less than 27 days)
When to see a doctor
See a doctor urgently if:
- Severe pain that stops you from doing everyday things
- Pain that does not go away with simple pain relief
- Bleeding between periods or after sex
Book a routine appointment if:
- Mild pain during periods that you think is not normal
- Feeling tired or low all the time
- Trouble getting pregnant (if trying to conceive)
Diagnosis
A doctor will ask about your symptoms, your periods, and your family history. They may do a pelvic exam (with your permission) and order scans like an ultrasound. The only way to confirm endometriosis for sure is with a laparoscopy (a small surgery using a camera).
Tests that may be done
- Pelvic ultrasound (a scan that uses sound waves to look at your organs)
- Laparoscopy (keyhole surgery under general anaesthetic to see and possibly remove endometriosis tissue)
What to expect at your appointment
Diagnosis can take time because the symptoms are similar to other conditions. Be patient and honest with your doctor. They may refer you to a gynaecologist (a doctor specialising in women's health) for further tests.
Treatment
Treatment aims to reduce pain, manage symptoms, and help you live a full life. Your doctor will work with you to find the best plan, which may include lifestyle changes, medicines, or surgery.
Self-care at home
- Apply a hot water bottle or heating pad to your lower belly
- Take warm baths to relax muscles
- Try gentle exercise like walking or swimming to ease pain
- Get enough rest and sleep
Medical treatments
Common treatments include pain relievers (such as ibuprofen or paracetamol – always follow the package instructions) and hormone therapies that can reduce or stop periods. These include contraceptive pills, hormone patches, or devices like the Mirena coil. A doctor will help you choose what is safest for your age.
When is surgery considered?
If pain is severe and other treatments haven't helped, a doctor might recommend a laparoscopy to remove the endometriosis tissue. This can improve symptoms, but the tissue can grow back.
Living with this condition
Endometriosis can be unpredictable. Some days you may feel fine, other days pain may limit what you can do. Plan ahead for your period – keep pain relief and a hot water bottle handy. Let your school or workplace know so they can support you.
Lifestyle tips
- Track your symptoms in a diary to help you and your doctor
- Reduce stress with activities like reading, drawing, or meditation
- Stay active – even light movement can help
Diet and exercise
Eating a balanced diet with plenty of fruits, vegetables, and whole grains may help reduce inflammation. Some people find cutting down on red meat, caffeine, and gluten helps. Regular exercise like yoga or cycling can improve pain and mood.
Mental health and emotional wellbeing
Living with constant pain can make you feel frustrated, anxious, or sad. It is okay to feel this way. Talk to a trusted adult or a counsellor. Many teenagers with endometriosis go on to do well with the right support.
Prevention
There is no known way to prevent endometriosis. However, early diagnosis and management can help reduce symptoms and improve quality of life.
Complications
If left untreated
- Chronic (long-lasting) pain that affects school, friendships, and daily life
- Feeling very tired or low all the time
- Possible difficulty getting pregnant in the future (but many women with endometriosis do become pregnant)
Long-term outlook
With the right treatment and support, most teenagers with endometriosis can lead active, happy lives. Symptoms often improve with age, and new treatments are being developed all the time.
