pleurisy in pregnancy

Overview

Pleurisy is inflammation of the pleura, the thin lining that surrounds your lungs. When this lining swells, it can cause sharp chest pain, especially when you breathe in, cough, or move. During pregnancy, pleurisy can be uncomfortable and worrying, but with the right care, most people recover fully and go on to have a healthy pregnancy.

Pleurisy is not one of the most common conditions in pregnancy, but it can happen. When it does, it is usually because of a chest infection, a blood clot, or an autoimmune condition. It is important to see a doctor quickly because some underlying causes need urgent treatment.

Any pregnant person can develop pleurisy, but it is more likely if you have asthma, a long-term lung condition, an autoimmune disease, or a personal or family history of blood clots. It can happen at any stage of pregnancy.

Symptoms

Common symptoms

• Sharp chest pain that gets worse when you breathe in, cough, or move
• Shortness of breath
• Dry cough
• Mild fever or sweating
• Pain that spreads to your shoulder or upper belly

Symptoms in children

• If you are a pregnant teenager, the symptoms of pleurisy are the same as for older adults. It is especially important to see a doctor promptly, because pregnancy affects which treatments are safe.

Symptoms in older adults

• Women over 35 who are pregnant can get the same symptoms, but may also feel more exhausted or dizzy. Any chest pain in pregnancy should be checked without delay.

Causes

Main causes

• Viral infection, such as a cold or flu
• Bacterial pneumonia
• A blood clot in the lung (pulmonary embolism)
• Autoimmune conditions, like lupus or rheumatoid arthritis

Risk factors

• Having a lung infection during pregnancy
• A personal or family history of blood clots
• Being on bed rest or inactive for long periods
• Smoking or exposure to second-hand smoke
• A weakened immune system

When to see a doctor

See a doctor urgently if:

• If you have sharp chest pain when you breathe, shortness of breath, or a heavy cough
• If you feel faint, very unwell, or your lips look blue

Book a routine appointment if:

• If you have a cough or chest discomfort that lasts more than a few days
• If you have been near someone with a chest infection and feel unwell

Diagnosis

Your doctor will listen to your chest, ask about your symptoms, and review your pregnancy history. They may also order imaging tests to look at your lungs and the lining around them.

Tests that may be done

• Chest X-ray (with a lead apron to protect your baby)
• Blood tests to check for infection, inflammation, or clotting problems
• An ultrasound of the chest to look for fluid around the lung
• An ECG to check that your heart is working as it should
• Sometimes a CT scan, if a blood clot is suspected — the benefit almost always outweighs the small risk

What to expect at your appointment

Most tests are quick and painless. You may need to sit or lie still for a few minutes. Your doctor will explain the results and work with you to create a plan that is safe for you and your baby.

Treatment

Treatment for pleurisy in pregnancy depends on the cause. The main goals are to relieve pain, treat the underlying problem, and protect both you and your baby. Your healthcare team will talk through each step with you before starting anything.

Self-care at home

• Rest until the pain and breathlessness improve
• Apply a warm compress to your chest for comfort
• Try gentle breathing exercises as directed by your doctor
• Drink plenty of water to stay hydrated
• Sleep propped up with extra pillows to make breathing easier
• Take only medicines that your doctor or pharmacist confirms are safe in pregnancy

Medical treatments

Depending on the cause, your doctor may recommend an antibiotic for a bacterial infection, anti-inflammatory treatment for inflammation, blood-thinning medication if a blood clot is found, or medicines to manage an autoimmune condition. All medicines are chosen carefully to be as safe as possible during pregnancy. In more serious cases, you may need oxygen or hospital care.

When is surgery considered?

Surgery is rarely needed for pleurisy. If a large amount of infected fluid collects around the lung, a doctor may drain it using a thin needle or tube. This is done by a specialist team and is usually safe in pregnancy.

Living with this condition

While you recover, take things at a slower pace. Avoid heavy lifting and strenuous activities. You can usually return to normal routines once pain and breathlessness settle, but check with your doctor first.

Lifestyle tips

• Do not smoke and avoid smoky places
• Take all medicines exactly as prescribed
• Keep your antenatal and follow-up appointments
• Plan regular rest breaks during the day

Diet and exercise

Eat a balanced diet with plenty of fruits, vegetables, and whole grains to support your immune system. Gentle activity like short walks is often fine once symptoms improve, but always ask your doctor or midwife before starting or changing exercise.

Mental health and emotional wellbeing

Being unwell during pregnancy can bring extra worry and anxiety. It is completely normal to feel this way. Talk openly with your midwife, doctor, or a trusted friend. They can help you find ways to cope and, if needed, connect you with a maternal mental health professional.

Prevention

You cannot always prevent pleurisy, especially the viral type. But you can lower your risk by staying active in a way your doctor approves, getting recommended vaccines, managing any long-term health condition carefully, and avoiding smoking.

Vaccines

Vaccines for flu, COVID-19, and whooping cough are often recommended in pregnancy to reduce the risk of serious lung infections. Your antenatal team can tell you which vaccines are right for you and when to get them.

Screening programmes

There is no routine screening test for pleurisy. If you have chest pain or other symptoms, your doctor will examine you thoroughly to find the cause.

Complications

If left untreated

• The underlying cause can get worse, especially if it is a bacterial infection or a blood clot
• Fluid may build up around the lung, making it harder to breathe
• A blood clot can become dangerous if not treated promptly

Long-term outlook

With early and proper care, the outlook for pleurisy in pregnancy is very good. Most women recover fully without problems for themselves or their babies. Your healthcare team will keep you well monitored, and you can expect to feel better over time.
