Thoracic Endometriosis
Cyclical Chest Symptoms — Investigation & Treatment, London

If you experience chest pain, breathlessness, or a collapsed lung that occurs cyclically — around the time of your period — you may have thoracic endometriosis. This is an underdiagnosed condition that I investigate thoroughly and treat in close collaboration with specialist gynaecologists.

What is Thoracic
Endometriosis?

Endometriosis is a condition in which tissue similar to the lining of the womb grows in other parts of the body. When this occurs in or around the chest — including on the diaphragm, the pleura (lung lining), or within the lung itself — it is known as thoracic endometriosis.

Because the endometrial tissue responds to the same hormonal changes as the womb lining, symptoms typically occur in a cyclical pattern — appearing around the time of menstruation and improving between periods. This cyclical pattern is one of the most important diagnostic clues, and is often overlooked for many years.

Thoracic endometriosis is rare but likely underdiagnosed. If you have a known diagnosis of endometriosis and experience cyclical chest symptoms, or if your chest symptoms have never been satisfactorily explained, a thorough investigation is warranted. I work closely with specialist gynaecologists to ensure that both the thoracic and gynaecological aspects of the condition are comprehensively managed.

Symptoms that may indicate thoracic endometriosis
  • Chest pain occurring around the time of your period
  • Breathlessness that is cyclical or worsens at certain times of the month
  • Coughing up blood (haemoptysis) linked to menstruation
  • Recurrent pneumothorax (collapsed lung) around the time of your period
  • Known diagnosis of endometriosis with unexplained chest symptoms
A collaborative approach to care

Thoracic endometriosis requires both a thoracic surgical and a gynaecological perspective. I work alongside specialist gynaecologists to ensure you receive a comprehensive assessment and treatment plan — addressing both the chest manifestations and the underlying endometriosis together. This joined-up approach leads to better outcomes and reduces the risk of recurrence.

How is it investigated?

Investigation includes a detailed history, CT and MRI imaging, and in some cases bronchoscopy or thoracoscopy. Timing symptoms carefully in relation to the menstrual cycle is essential. I will guide you through the appropriate investigations and ensure a thorough and compassionate assessment.

How do I know if my chest symptoms could be thoracic endometriosis?
The key indicator is cyclical timing — symptoms that appear around menstruation and improve between periods. If you have chest pain, breathlessness, or a collapsed lung that follows this pattern, particularly if you have a known diagnosis of endometriosis, thoracic endometriosis should be investigated. A consultation with a detailed history is the important first step.
I have endometriosis — should I be worried about chest symptoms?
Not all chest symptoms in women with endometriosis are thoracic endometriosis — but if your symptoms are cyclical, they absolutely warrant investigation. Many patients with thoracic endometriosis have waited years for a diagnosis. An early and thorough assessment means earlier, more effective treatment.
What does treatment involve?
Treatment depends on the extent and location of the endometriosis. Options include hormonal medical therapy, keyhole surgical removal of endometrial deposits from the diaphragm or pleura, repair of diaphragmatic defects, and pleurodesis to prevent recurrent pneumothorax. I work with gynaecological colleagues to decide on the best combined approach for each patient.
Can thoracic endometriosis cause a collapsed lung?
Yes — catamenial pneumothorax (a collapsed lung occurring around menstruation) is one of the recognised presentations of thoracic endometriosis. It occurs when endometrial tissue creates holes in the diaphragm, allowing air to pass from the abdomen into the chest. Surgical repair of these diaphragmatic defects, combined with pleurodesis, is highly effective.
Do I need a GP referral?
No. Self-referrals are welcome for private consultations. Appointments are typically available within 2–3 days. If you have been experiencing cyclical chest symptoms and would like a specialist opinion, please do get in touch — even if you are not sure whether your symptoms are related to endometriosis.
