Adenomyosis

Overview

Adenomyosis is a condition where the tissue that normally lines the womb (the endometrium) grows into the muscular wall of the womb. This can cause the womb to become enlarged and tender, leading to symptoms like heavy, painful periods.

Adenomyosis is fairly common, especially in women in their 40s and 50s, though it can affect younger women too. Many women have it without knowing because they have no symptoms.

Adenomyosis mainly affects women of reproductive age, particularly those who have had children. It is less common in teenagers and women who have not given birth.

Symptoms

Common symptoms

• Heavy or prolonged menstrual bleeding
• Severe cramping or sharp, stabbing pain during periods
• Chronic pelvic pain or lower back pain
• Pain during or after sexual intercourse
• Bloating or a feeling of fullness in the lower belly
• Spotting between periods

Symptoms in children

• Adenomyosis is extremely rare in children and teenagers. If a young person has very painful periods or heavy bleeding, it is more likely due to other conditions like endometriosis or hormonal imbalances.

Symptoms in older adults

• In women nearing menopause, symptoms may worsen before eventually easing after menopause when periods stop. However, some postmenopausal women may still have pain or bleeding, which needs a doctor's evaluation.

Causes

Main causes

• The exact cause is not fully understood. It is believed that the inner lining of the womb grows into the muscle wall, possibly due to damage from childbirth or other uterine procedures (like C-sections or fibroid removal).
• Some research suggests it may be linked to inflammation or problems with the immune system.

Risk factors

• Being in your 40s or 50s (perimenopausal age)
• Having had one or more pregnancies
• Previous uterine surgery (such as a C-section or fibroid removal)
• Having endometriosis (a related condition where womb-like tissue grows outside the womb)

When to see a doctor

See a doctor urgently if:

• If you have heavy bleeding that causes dizziness or weakness, or if you soak through a pad or tampon every hour for more than two hours.
• If you have sudden, severe pelvic or lower abdominal pain that does not improve.

Book a routine appointment if:

• If you have painful periods that make it hard to go to work or school, or that do not get better with over-the-counter pain relief.
• If you have heavy periods that last longer than 7 days or that happen more often than every 24 days.
• If you have pain during sex or chronic pelvic pain that bothers you.

Diagnosis

Adenomyosis is often diagnosed based on your symptoms and a pelvic exam. Your doctor may feel that your womb is enlarged or tender. Imaging tests can help confirm the diagnosis.

Tests that may be done

• Pelvic ultrasound – a scan using sound waves to look at the womb. It can show thickening of the womb wall or cystic areas.
• Magnetic resonance imaging (MRI) – a more detailed scan that can show the depth of tissue growth into the womb muscle.
• Sometimes a biopsy (taking a small sample of womb tissue) is done to rule out other conditions.

What to expect at your appointment

Your doctor will ask about your periods, pain, and any history of pregnancies or surgeries. They may do a pelvic exam and then recommend an ultrasound or MRI. The process is usually straightforward and can often be done in a clinic or hospital without overnight stay.

Treatment

Treatment for adenomyosis depends on how severe your symptoms are and whether you plan to have children in the future. Options range from managing symptoms at home to medications or surgery. Your doctor will help you decide what is best for you.

Self-care at home

• Apply a heating pad or hot water bottle to your lower belly during cramps.
• Take warm baths to relax muscles.
• Use over-the-counter pain relievers (ask your pharmacist for advice).
• Gentle exercise like walking or yoga may help ease pain.
• Practice relaxation techniques such as deep breathing or meditation.

Medical treatments

Doctors may recommend hormonal treatments to help control heavy bleeding and pain. These can include hormonal contraceptives (like the pill, patch, or intrauterine system), medications that suppress hormone production, or other non-hormonal medicines. Many women get relief from these options. Always discuss the risks and benefits with your doctor.

When is surgery considered?

If symptoms are severe and other treatments have not worked, surgery may be an option. For women who do not wish to have more children, a hysterectomy (removal of the womb) is the only cure for adenomyosis. In some cases, less invasive procedures like endometrial ablation (removing the lining of the womb) might help, but this is not suitable if you want to get pregnant.

Living with this condition

Living with adenomyosis can be challenging, but many women manage well with a combination of treatments and self-care. Keeping track of your symptoms and periods can help you and your doctor find the best approach. Be patient with yourself on bad days, and ask for help when you need it.

Lifestyle tips

• Try to get regular, moderate exercise – it can reduce pain and improve mood.
• Find ways to reduce stress, such as meditation, journaling, or talking to someone you trust.
• Use period-tracking apps to monitor symptoms and plan ahead.
• Wear comfortable clothing and use heat packs for pain.

Diet and exercise

Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins may help reduce inflammation. Some women find that cutting down on caffeine and salty foods helps with bloating. Regular physical activity, like brisk walking or swimming, can improve pelvic blood flow and ease pain.

Mental health and emotional wellbeing

Chronic pain and heavy bleeding can affect your mood, energy, and relationships. It is normal to feel frustrated, anxious, or sad. If these feelings last or get in the way of daily life, talk to your doctor. They can refer you to a counselor or suggest support groups. Remember: your mental health is just as important as your physical health. If you ever feel like you need urgent help, reach out to a crisis helpline in your area.

Prevention

There is no known way to prevent adenomyosis, because the exact cause is not clear. However, early diagnosis and treatment can help manage symptoms and prevent complications.

Screening programmes

There is no routine screening test for adenomyosis. Regular gynecological check-ups and talking to your doctor about any menstrual symptoms are important.

Complications

If left untreated

• Severe anemia (low red blood cells) due to heavy bleeding, causing fatigue and weakness.
• Chronic pelvic pain that affects work, relationships, and daily life.
• Painful periods that become progressively worse over time.

Long-term outlook

Adenomyosis is not life-threatening, and many women live normal lives with treatment. Symptoms often improve after menopause. With the right care – whether lifestyle changes, medications, or surgery – most women can find relief and maintain a good quality of life.
