Pulmonary Fibrosis
Urgent
Pulmonary fibrosis is a condition in which lung tissue becomes scarred and stiff. The scarring makes it harder for oxygen to move from the lungs into the blood and can gradually make breathing more difficult. Symptoms often develop slowly and may include shortness of breath, a persistent dry cough, tiredness, weakness, and reduced ability to exercise. The course varies depending on the cause and type.

When to Seek Medical Attention
Seek prompt medical assessment for worsening breathlessness, a significant decline in exercise tolerance, new or worsening chest pain, coughing up blood, fainting, or rapidly worsening respiratory symptoms. Severe difficulty breathing requires emergency medical attention.

Overview
Pulmonary fibrosis is a condition in which lung tissue becomes scarred and stiff. The scarring makes it harder for oxygen to move from the lungs into the blood and can gradually make breathing more difficult. Symptoms often develop slowly and may include shortness of breath, a persistent dry cough, tiredness, weakness, and reduced ability to exercise. The course varies depending on the cause and type.

Chest Pain
Pain Radiating To Jaw
Causes 5
Pulmonary fibrosis can have many causes. Some cases result from long-term exposure to substances such as asbestos, silica dust, certain chemicals, or other environmental and occupational irritants. Certain medicines, radiation therapy, autoimmune diseases, and some infections can also damage the lungs. In many people, no specific cause is found; this is called idiopathic pulmonary fibrosis.
Alcohol
High Cholesterol
Insulin Resistance
Obesity
Sedentary Lifestyle
Risk Factors
Risk factors for pulmonary fibrosis include older age, smoking, exposure to occupational or environmental dusts and chemicals, and certain autoimmune diseases. Some medicines and previous radiation treatment can increase risk. A family history of pulmonary fibrosis may also be relevant in some cases. Risk depends on the specific type of fibrosis and its underlying cause.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Pulmonary fibrosis is diagnosed using symptoms, medical history, physical examination, and lung tests. High-resolution CT imaging can show characteristic patterns of lung scarring. Pulmonary function tests measure lung capacity and gas exchange. Blood tests may help identify autoimmune or other causes. In selected cases, additional procedures such as bronchoscopy or lung biopsy may be needed.
Prevention
Key Prevention Tips
Not all cases of pulmonary fibrosis can be prevented, particularly when the cause is unknown or related to inherited factors
Avoiding cigarette smoke and occupational exposure to asbestos, silica, dust, fumes, and other lung irritants can reduce risk
Appropriate respiratory protection should be used in hazardous workplaces
People taking medicines associated with lung injury should follow medical monitoring recommendations
Prevention Guidance
Not all cases of pulmonary fibrosis can be prevented, particularly when the cause is unknown or related to inherited factors. Avoiding cigarette smoke and occupational exposure to asbestos, silica, dust, fumes, and other lung irritants can reduce risk. Appropriate respiratory protection should be used in hazardous workplaces. People taking medicines associated with lung injury should follow medical monitoring recommendations.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
