Endometriosis living in pregnancy

Overview

Endometriosis is a condition where tissue similar to the lining of the womb grows in other places, like the ovaries or pelvis. During pregnancy, hormonal changes can affect this tissue. Many women find their symptoms improve, but some may still experience pain or other issues. Managing endometriosis during pregnancy focuses on comfort and a healthy pregnancy.

Endometriosis affects about 1 in 10 women of reproductive age. Among those who become pregnant, many have a normal pregnancy, though symptoms and risks are monitored.

This condition affects women who have endometriosis and are either pregnant or planning to become pregnant.

Symptoms

Common symptoms

• Pelvic pain or pressure, especially in early pregnancy
• Pain during or after sex
• Tiredness and fatigue
• Bloating or constipation

Causes

Main causes

• Endometriosis is caused by endometrial‑like tissue growing outside the womb. The exact reason is not fully understood.
• During pregnancy, rising hormones like progesterone often cause the extra tissue to shrink and become less active, which can reduce symptoms.

Risk factors

• Family history of endometriosis
• Starting your period at a young age (before 11)
• Short menstrual cycles (fewer than 27 days)

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency symptoms listed above
• If you feel your baby moving less than usual

Book a routine appointment if:

• If your endometriosis symptoms change or worsen during pregnancy
• For all your scheduled antenatal appointments

Diagnosis

Endometriosis is usually diagnosed before pregnancy through laparoscopy or imaging. During pregnancy, it is diagnosed based on your medical history and symptoms. Invasive tests are avoided.

Tests that may be done

• Ultrasound scan (abdominal or vaginal) to check for cysts or tissue growth
• Blood tests (like CA‑125) may be used but are not specific
• MRI scan if more detail is needed, though rarely used in pregnancy

What to expect at your appointment

Your doctor will review your symptoms and pregnancy progress. They may suggest monitoring your pain levels and baby's growth closely.

Treatment

Treatment for endometriosis during pregnancy focuses on managing symptoms safely for you and your baby. Many pain relief options are limited, so your doctor will work with you to find the safest approach.

Self-care at home

• Rest when you need to and avoid overdoing physical activity
• Apply a warm (not hot) pack to your lower belly for short periods
• Do gentle stretches or pregnancy yoga to reduce pelvic tension

Medical treatments

Pain relief that is considered safe during pregnancy may be recommended. Always consult your doctor before taking any medication. Hormonal treatments are not used during pregnancy.

When is surgery considered?

Surgery for endometriosis is almost never needed during pregnancy. It is only considered in very rare cases, such as if a cyst twists or ruptures and causes an emergency.

Living with this condition

Listen to your body. Pace yourself and rest when symptoms flare. Keep a symptom diary to share with your doctor. Plan light activities and ask for help with heavy tasks.

Lifestyle tips

• Get plenty of rest, but also gentle movement like walking
• Try to reduce stress with breathing exercises or mindfulness
• Avoid heavy lifting if you have pelvic pain

Diet and exercise

Eat a balanced diet with lots of fibre, fruits, and vegetables to help with constipation. Gentle exercise like walking or swimming can keep you active without straining. Avoid high‑impact activities if you have pelvic pain.

Mental health and emotional wellbeing

Living with endometriosis during pregnancy can cause worry or sadness. It is normal to feel anxious. Talk to your midwife or a counsellor. If you feel very low or have thoughts of harming yourself, get help immediately.

Prevention

Endometriosis cannot be prevented. However, early diagnosis and good symptom management can help reduce its impact on your pregnancy.

Vaccines

There is no vaccine for endometriosis.

Screening programmes

There is no routine screening test for endometriosis. If you have symptoms, talk to your doctor before or during pregnancy.

Complications

If left untreated

• increased risk of miscarriage (though most pregnancies are healthy)
• Higher chance of preterm labour or low birth weight
• Pain and discomfort that may affect daily life and mental health

Long-term outlook

Most women with endometriosis have a healthy pregnancy and give birth to a healthy baby. Symptoms often improve during pregnancy, especially in the second and third trimesters. After birth, some symptoms may return, but you can work with your doctor to manage them.
