endometriosis pain at night

Overview

Endometriosis (en-doh-mee-tree-OH-sis) is a condition where tissue similar to the lining of the womb grows outside the womb, for example on the ovaries, fallopian tubes, or the lining of the pelvis. This tissue responds to hormones, just like the womb lining does, which can cause inflammation, scar tissue, and pain. Many people with endometriosis notice that pain becomes worse at night, often because they are still, less distracted, and trying to sleep.

Yes. Around 1 in 10 people assigned female at birth have endometriosis. It is one of the most common causes of pelvic pain in women and people who menstruate.

Anyone with a uterus can develop endometriosis, usually between puberty and menopause. Some people only find out they have it later in life after years of symptoms.

Symptoms

Common symptoms

• Pelvic pain that gets worse around the time of your period or wakes you up at night
• Severe period cramps that are hard to ease
• Pain during or after sex
• Pain when opening your bowels or passing urine, especially during your period
• Heavy periods or bleeding between periods
• Tiredness, difficulty sleeping, or feeling exhausted after a poor night's sleep

Symptoms in children

• In teens and young people, symptoms can include very painful periods, lower belly or pelvic pain, and pain that makes them miss school, social events, or activities.

Symptoms in older adults

• Symptoms may improve after menopause, but some people still have pelvic pain, pain with sex, or pain when passing stools.
• If you use hormone replacement therapy, it can sometimes reactivate endometriosis, so tell your doctor you have or may have endometriosis before starting hormone treatment.

Causes

Main causes

• Menstrual fluid containing womb-like cells can flow backwards through the fallopian tubes and settle in the pelvis instead of leaving the body. This is called retrograde menstruation.
• Hormones, especially oestrogen, stimulate these displaced cells to grow and shed in rhythm with your cycle, causing inflammation and pain.
• The immune system may not be able to clear the misplaced cells, so the tissue keeps building up.
• Genetics may play a part, as endometriosis can run in families.

Risk factors

• A close family member, such as a mother or sister, with endometriosis
• Starting your first period at a young age, for example before age 11
• Having short or frequent period cycles, for example less than 27 days apart
• Long or heavy periods
• Having never given birth is linked with a slightly higher risk, although it does not cause endometriosis

When to see a doctor

See a doctor urgently if:

• If you are pregnant and have any pelvic pain or bleeding, seek urgent maternity or emergency advice today.
• If you have severe pain with fever, vomiting, or heavy bleeding, contact a healthcare provider immediately.

Book a routine appointment if:

• If period pain is getting worse over time
• If pain wakes you up at night regularly
• If you are missing school, work, or social activities because of pelvic pain
• If pain does not improve with simple self-care like heat and rest

Diagnosis

There is no simple bedside blood test for endometriosis. A doctor will ask about your symptoms, examine you, and sometimes arrange scans. The only way to be absolutely certain is with keyhole surgery called laparoscopy, but not everyone needs this. Some people are treated based on their symptoms and response to treatment.

Tests that may be done

• A detailed discussion of your symptoms, periods, and how pain affects your sleep and life
• A pelvic exam, where the doctor gently checks your uterus, ovaries, and pelvis for tenderness or lumps
• An ultrasound scan to look at your womb and ovaries
• An MRI scan in some cases, which gives a detailed picture of your pelvic organs
• Laparoscopy — a small operation with a camera through tiny cuts in your tummy, which can confirm endometriosis and sometimes remove tissue at the same time

What to expect at your appointment

Diagnosis can sometimes take years, so if you feel your concerns are dismissed, do not be afraid to ask for a referral to a specialist gynaecologist, a doctor who focuses on women's reproductive health. A proper diagnosis opens the door to treatments and support. You do not have to live with severe pain in silence.

Treatment

There is no cure for endometriosis for everyone, but the condition can usually be managed well. Treatment aims to reduce pain, control symptoms, protect fertility where possible, and improve sleep and quality of life. Your plan should be shaped around your symptoms, how you feel, and your future family plans.

Self-care at home

• Use a hot-water bottle, heating pad, or heat pack wrapped in a cloth on your lower tummy for 15 to 20 minutes at a time
• Take a warm bath or shower before bed to relax your muscles
• Try sleeping on your side with a pillow between your knees, or place a pillow under your knees
• Practise slow, gentle breathing or relaxation exercises before you go to sleep
• Keep a symptom and sleep diary to notice patterns and share them with your healthcare team

Medical treatments

Your doctor may suggest hormonal treatment, such as certain types of contraception, to reduce the hormonal changes that make endometriosis tissue grow. They may also offer pain-relieving medicines for flare-ups. Some treatments temporarily pause your periods or reduce oestrogen, which can ease pain. Always discuss the benefits and possible side effects of any treatment, and tell your doctor if you are hoping to become pregnant now or in the future.

When is surgery considered?

If other treatments do not help enough, keyhole surgery called laparoscopy can remove endometriosis tissue and help relieve pain. In more severe cases, a specialist may talk about removing the womb, ovaries, or fallopian tubes. This is a major decision and not the right choice for everyone, so take time to discuss it thoroughly with your specialist.

Living with this condition

Living with endometriosis means learning to work with your body rather than against it. Plan for difficult days, let yourself rest without guilt, and be open with close friends, family, or employers about the support you need.

Lifestyle tips

• Try to keep a regular sleep schedule, even at weekends
• Use heat in the evening to relax your pelvic muscles
• Try gentle movement or stretching before bed
• Cut down on caffeine from late afternoon onwards
• Try meditation, calming music, or a wind-down bedtime routine

Diet and exercise

No single diet is proven to cure endometriosis, but eating a balanced, mostly anti-inflammatory diet may help. Plenty of vegetables, fruit, whole grains, and healthy fats can support your body. Gentle exercise such as walking, swimming, or yoga can ease tension and improve sleep, but listen to your body and rest on painful days.

Mental health and emotional wellbeing

Living with chronic pain is tiring and can affect your mood. It is normal to feel frustrated, anxious, or low at times. Counselling and talking therapies can help. If you ever feel hopeless or have thoughts of harming yourself, reach out to your local crisis service or call your emergency number right away.

Prevention

There is no proven way to prevent endometriosis. The best thing you can do is learn the early signs, seek help promptly, and build a strong relationship with your healthcare team so you can get treatment and support sooner.

Vaccines

There is currently no vaccine to prevent endometriosis.

Screening programmes

There is no routine screening test for endometriosis. If you have symptoms, talk to your doctor rather than waiting for a screening programme.

Complications

If left untreated

• Persistent pain can disrupt sleep, work, relationships, and everyday activities
• Endometriosis can cause adhesions, which are bands of scar tissue that may make pain worse
• It can also affect fertility, but many people with endometriosis can and do become parents, with or without medical help
• Without support, chronic pain can lead to anxiety, low mood, and a feeling of isolation

Long-term outlook

Endometriosis is a long-term condition, but the outlook is often hopeful. Many people find a treatment plan that greatly improves their pain and sleep. Symptoms can change over time, and research is always improving care. You are not alone, and you deserve compassionate support.
