Conditions

Interstitial Lung Disease (ILD) refers to a group of conditions that affect the lung tissue itself. In these conditions, the lungs may become inflamed or develop scarring (fibrosis), which can lead to breathlessness and a persistent dry cough. ILD is a specialist area of respiratory medicine, and the exact type of ILD is important, as treatment and outlook can vary significantly.

Common symptoms include gradually worsening breathlessness, dry cough, fatigue, and reduced exercise tolerance. Some people are diagnosed incidentally after a CT scan performed for another reason. ILD includes a range of conditions such as idiopathic pulmonary fibrosis, inflammation related to autoimmune disease, environmental exposures, or previous lung injury. Because these conditions can appear similar, careful assessment is essential.

Diagnosis and management rely on detailed review of imaging, lung function trends, and clinical history, often as part of a specialist multidisciplinary approach. Treatment is tailored to the individual and may include monitoring, antifibrotic medication, or immunosuppressive therapy depending on the pattern and behaviour of disease. A specialist review can help clarify the diagnosis, assess progression, and ensure the most appropriate treatment plan is in place.

Sarcoidosis is an inflammatory condition that can affect several parts of the body, most commonly the lungs and lymph nodes. It is characterised by small clusters of inflammation (granulomas). In many people, sarcoidosis is mild and may settle on its own, but in others it can cause ongoing symptoms and require specialist care.

When the lungs are involved, symptoms may include a persistent dry cough, breathlessness, chest discomfort, and fatigue. Sarcoidosis can also affect other organs, leading to skin changes, eye irritation, joint pain, or enlarged lymph nodes. Some people have no symptoms and are diagnosed incidentally after a chest scan.

Diagnosis involves imaging, lung function tests, and blood tests, sometimes supported by a biopsy. Not all patients require treatment, and many are monitored over time. When needed, treatment aims to control inflammation while minimising side effects. A specialist review can help confirm the diagnosis, assess the extent of involvement, and guide decisions about monitoring or treatment.

Asthma is a common condition that affects the airways, causing them to become inflamed and narrowed. This can lead to symptoms that come and go over time. With the right treatment, most people with asthma can achieve good control and lead a normal, active life.

Typical symptoms include wheeze, breathlessness, cough, and chest tightness. These may be worse at night, during exercise, after viral infections, or with exposure to triggers such as allergens or cold air. It is important to confirm the diagnosis properly, as not all respiratory symptoms are due to asthma. Assessment usually involves breathing tests and, where appropriate, additional tests to understand airway inflammation and exclude other causes.

Treatment focuses on controlling inflammation and preventing flare-ups. Most patients use combination inhalers containing both a preventer and a reliever, sometimes as part of a single inhaler strategy (MART). For those with more difficult-to-control asthma, further specialist assessment can help optimise treatment, including consideration of advanced therapies. With accurate diagnosis and the right approach, symptoms can usually be well controlled.

COPD is a long-term lung condition that causes narrowing of the airways and damage to the air sacs, leading to breathlessness that often worsens over time. It most commonly affects people with a history of smoking, although it can also occur in non-smokers. While COPD cannot be reversed, the right treatment can significantly improve symptoms and quality of life.

Common symptoms include breathlessness, persistent cough, sputum production, wheeze, and reduced exercise tolerance. These symptoms often develop gradually and may initially be attributed to ageing or reduced fitness. COPD is diagnosed using breathing tests, sometimes alongside imaging, to confirm airflow limitation and distinguish it from conditions such as asthma.

Treatment focuses on relieving symptoms, reducing flare-ups, and slowing progression. This may include long-acting inhalers, pulmonary rehabilitation, vaccinations, and support with smoking cessation where relevant. Some patients experience flare-ups, often triggered by infections, which can usually be reduced with optimised treatment. A specialist review can help confirm the diagnosis, ensure inhalers are appropriate, and explore further options where needed.

Bronchiectasis is a condition where the airways become widened and prone to inflammation and infection. This can lead to a persistent cough, regular sputum production, and repeated chest infections. Although it is a long-term condition, symptoms can often be significantly improved with the right treatment and ongoing management.

Common symptoms include daily sputum production, recurrent infections, breathlessness, fatigue, and occasionally coughing up blood. Bronchiectasis can develop after previous infections, due to underlying immune or autoimmune conditions, or alongside other lung diseases such as asthma or COPD. In some cases, no clear cause is found.

Diagnosis is usually confirmed with a CT scan, alongside tests to identify contributing factors.

Obstructive Sleep Apnoea (OSA) is a common condition in which the airway repeatedly narrows or closes during sleep. This leads to brief pauses in breathing and disrupted sleep, often without the person being aware. Many people notice symptoms such as loud snoring or waking unrefreshed, along with persistent daytime tiredness. With appropriate treatment, symptoms can improve significantly.

Typical features include snoring, witnessed pauses in breathing, gasping during sleep, morning headaches, poor concentration, and excessive daytime sleepiness. OSA is more common in people who are overweight, but it can affect individuals of all body types. It is important to recognise and assess these symptoms, as untreated OSA can contribute to high blood pressure, heart problems, and reduced alertness.

Diagnosis is usually made with a sleep study, often performed at home. Treatment is tailored to the individual and may include lifestyle measures, positional therapy, oral devices, or CPAP therapy. When used consistently, CPAP is highly effective and can significantly improve energy levels, concentration, and overall quality of life.

Pneumonia is an infection of the lungs, most commonly caused by bacteria or viruses. It can range from a mild illness to something more serious, particularly in older adults or those with underlying health conditions. Most people recover well with appropriate treatment, although it can take several weeks to feel fully back to normal.

Typical symptoms include fever, cough (often with sputum), breathlessness, chest discomfort when breathing deeply, fatigue, and reduced appetite. While many people improve steadily, it is common for cough and tiredness to persist for a short time during recovery. Pneumonia can affect anyone, but the risk is higher in those who smoke or have conditions such as asthma, COPD, or diabetes.

You should seek medical advice if symptoms are not improving as expected, if breathlessness persists, or if infections keep recurring. Urgent attention is needed for severe breathlessness, confusion, worsening chest pain, or significant coughing up of blood. A specialist review can help confirm recovery, identify any underlying issues, and reduce the risk of future infections.

The pleura are thin layers of tissue that line the lungs and the inside of the chest wall. A small amount of fluid normally sits between these layers to allow smooth breathing. Pleural conditions occur when this space is affected by inflammation, excess fluid, air, or thickening. In many cases, the underlying cause can be identified and treated effectively.

Common pleural conditions include fluid around the lung (pleural effusion), inflammation of the lining (pleurisy), a collapsed lung (pneumothorax), and pleural thickening or scarring. Symptoms may include breathlessness, chest discomfort, cough, or sharp chest pain. Causes vary widely and can include infection, heart conditions, inflammation, or, less commonly, cancer.

You should seek medical advice if you have been told you have fluid around the lung, have persistent or worsening breathlessness, or ongoing chest pain. Urgent assessment is needed if symptoms come on suddenly and are severe. A specialist review focuses on identifying the cause, often using imaging and, where needed, sampling of fluid, to guide appropriate treatment and provide reassurance.

A pulmonary embolism (PE) occurs when a blood clot travels to the lungs and blocks part of the blood supply. This can cause sudden breathlessness or chest pain and requires urgent medical assessment. The severity can vary, but with prompt treatment, most people recover well.

Common symptoms include sudden breathlessness, sharp chest pain (often worse on breathing in), a fast heart rate, and occasionally coughing up blood or feeling light-headed. Risk is higher after surgery, long periods of immobility (such as long flights), pregnancy, or in people with a history of blood clots, although PE can sometimes occur without an obvious trigger.

Urgent medical attention is needed if these symptoms develop suddenly. Treatment is usually with blood-thinning medication (anticoagulation), which helps prevent further clots while the body clears the existing one. Most people recover fully, but some may have ongoing breathlessness or reduced exercise tolerance. A specialist review can help assess recovery, clarify ongoing treatment, and identify any longer-term complications if symptoms persist.

A lung nodule is a small spot seen on a chest X-ray or CT scan. They are very common and are often found incidentally when scans are done for other reasons. The majority of lung nodules are benign (non-cancerous) and may represent old infections, minor scarring, inflammation, or harmless growths.

In a small number of cases, a nodule may represent an early cancer, which is why careful assessment is important. The level of concern depends on factors such as the size and appearance of the nodule, whether it has changed over time, and individual risk factors such as age and smoking history.

Assessment focuses on reviewing imaging in detail and comparing with any previous scans. Some nodules are monitored with repeat CT scans over time, while a small number may require further tests. A specialist review can help clarify risk, provide reassurance, and ensure an appropriate follow-up plan is in place.

Breathing Pattern Disorder (sometimes called dysfunctional breathing) occurs when the normal rhythm and mechanics of breathing become disrupted. It is common and often overlooked. Many people feel persistently breathless despite normal lung tests, which can be frustrating and worrying. Importantly, this is a real and treatable condition.

Symptoms may include breathlessness that feels out of proportion to activity, difficulty taking a full breath, chest tightness, frequent sighing or yawning, and sometimes light-headedness or tingling.

Symptoms often fluctuate and may worsen with stress, fatigue, or after illness. Unlike asthma or COPD, lung tests are usually normal and inhalers may provide little benefit, although both conditions can sometimes coexist.

Diagnosis is based on symptoms and careful assessment to exclude other causes of breathlessness. Treatment focuses on breathing retraining, physiotherapy-led techniques, and gradual reconditioning. With the right support, most patients improve significantly. A specialist review can help confirm the diagnosis, provide reassurance, and guide a structured plan to restore normal breathing.

Respiratory symptoms and scan findings can sometimes be complex or unclear. A second opinion can help confirm a diagnosis, provide reassurance, or identify alternative explanations when symptoms are not improving as expected. Many patients seek review for persistent breathlessness or cough, uncertain diagnoses such as asthma, abnormal imaging findings, or ongoing symptoms despite treatment.

A second opinion involves a detailed and structured review of your case. This typically includes careful assessment of your symptoms, review of previous tests and imaging (including CT scans and X-rays), interpretation of lung function, and evaluation of current treatment. The aim is to clarify the diagnosis, ensure nothing has been missed, and provide clear, evidence-based recommendations tailored to you.

You may wish to seek a second opinion if your diagnosis remains uncertain, symptoms are not improving, or you have been advised to start long-term treatment and would like further reassurance. Respiratory conditions often require careful interpretation over time, and a specialist review can provide clarity, confidence, and a clear plan moving forward.
