10959 Pulmonary Fibrosis

Overview

Pulmonary fibrosis is a lung disease in which the tissue inside the lungs becomes thick, stiff, and scarred. This makes it harder for your lungs to expand and take in oxygen. Over time, the scarring can get worse, making it more difficult to breathe.

Pulmonary fibrosis is not common, but it is seen more often in older adults. It affects a small number of people worldwide, though it may be underdiagnosed because its early symptoms can be similar to other lung conditions.

It most often affects adults between 50 and 70 years old, and it is slightly more common in men. People with a history of smoking, some occupational dust exposure, or a family history of pulmonary fibrosis are at higher risk.

Symptoms

Common symptoms

• A dry, persistent cough that does not go away
• Shortness of breath, especially during or after physical activity
• Feeling unusually tired or weak
• Clubbing, or widening and rounding of the fingertips
• Unintentional weight loss or loss of appetite

Symptoms in children

• Pulmonary fibrosis is very rare in children, but when it occurs, symptoms can include fast breathing, a dry cough, poor growth or difficulty gaining weight, and feeling tired during play or activity.

Symptoms in older adults

• Older adults may notice increasing breathlessness when doing everyday tasks like dressing or walking short distances.
• They might become confused or restless if oxygen levels drop too low.
• Falls can become more common due to fatigue or weakness.
• A worsening cough or chest tightness may also appear.

Causes

Main causes

• In many cases, the cause is unknown; this is called idiopathic pulmonary fibrosis.
• Having an autoimmune disease, such as rheumatoid arthritis or scleroderma, that can affect the lungs
• Long-term exposure to harmful substances in the environment or workplace, such as asbestos dust, silica, metal dust, or certain chemicals
• Some types of radiation therapy or certain medicines can damage the lungs over time
• In rare cases, it runs in families due to genetic factors

Risk factors

• Smoking or a history of smoking
• Being middle-aged or older
• Male gender
• Working in farming, mining, construction, or other jobs with dust and fumes
• Having a close relative with pulmonary fibrosis

When to see a doctor

See a doctor urgently if:

• If you have new or worsening shortness of breath that limits your daily activities
• If you have a persistent dry cough that lasts more than three weeks
• If you have fever or feel unwell along with breathing problems

Book a routine appointment if:

• If you have a nagging cough or feel breathless after mild activity, make an appointment with your doctor.
• If you have risk factors such as smoking or a family history, it is reasonable to discuss a lung check with your doctor even if you feel fine.

Diagnosis

Your doctor will start by asking about your symptoms, medical history, and any exposures to dust or smoke. They will listen to your breathing with a stethoscope and may order breathing tests and imaging scans to look at your lungs.

Tests that may be done

• Chest X-ray to look for visible scarring or other lung changes
• CT scan, a detailed scan that gives clearer pictures of the lungs
• Spirometry, a breathing test that measures how much and how quickly you can exhale
• Lung function tests to check how well your lungs take in oxygen and remove carbon dioxide
• Blood tests to rule out other conditions and check for autoimmune diseases
• A biopsy, where a small piece of lung tissue is taken, may be needed in some cases to confirm diagnosis

What to expect at your appointment

Diagnosis may take time because the symptoms can look like other lung problems. You will likely be referred to a lung specialist (a pulmonologist) who will help confirm the diagnosis and work with you to create a care plan.

Treatment

There is no cure for most types of pulmonary fibrosis, but treatment can help relieve symptoms, slow the progression of scarring, and improve your quality of life. Your healthcare team will tailor a plan based on the type of pulmonary fibrosis you have and how severe it is.

Self-care at home

• Quit smoking and avoid secondhand smoke and other lung irritants like dust and strong chemicals
• Stay physically active within your limits – even gentle walking can help keep your muscles strong
• Use breathing techniques, such as pursed-lip breathing, to help cope with breathlessness
• Get enough rest and pace your activities during the day
• Ask about pulmonary rehabilitation, a program of exercise and education designed for people with lung conditions
• Take oxygen therapy exactly as prescribed if your doctor recommends it

Medical treatments

Medicines called anti-fibrotic agents can slow down lung scarring in some types of pulmonary fibrosis. Other treatments, such as corticosteroids or medicines that calm the immune system, may be used when an underlying condition like an autoimmune disease is responsible. Your doctor will explain the possible benefits and risks of any treatment they suggest. Always take your medications exactly as prescribed and discuss any concerns with your healthcare provider.

When is surgery considered?

For a small number of people with advanced pulmonary fibrosis who are otherwise healthy, a lung transplant may be an option. This is a major procedure and is not suitable for everyone. Your specialist team will discuss all options with you if this applies.

Living with this condition

Living with pulmonary fibrosis means learning to pace yourself. Break tasks into small steps, rest between activities, and ask for help when you need it. Many people find that planning their day around their energy levels helps them feel more in control.

Lifestyle tips

• Keep up with social connections – loneliness can make stress worse, so stay in touch with friends and family
• Avoid crowded places during flu season to reduce the risk of infections
• Wash your hands often and stay up to date with recommended vaccines
• Use an air filter or humidifier if indoor air feels dry or triggers your cough
• Seek support from a counselor or peer group if you feel overwhelmed

Diet and exercise

Eating a healthy, balanced diet helps you maintain your strength and weight, which is important because some people with pulmonary fibrosis lose weight unintentionally. If eating makes you breathless, try smaller, more frequent meals. Gentle exercise like walking or stretching, under the guidance of a physical therapist, can help keep your muscles functioning and improve your sense of well-being.

Mental health and emotional wellbeing

Breathlessness is frightening and can make everyday tasks feel stressful. It is common to feel anxious, depressed, or frustrated when living with a chronic lung condition. Expressing these feelings to a counselor, doctor, or support group can make a big difference. Your emotional well-being matters just as much as your physical health.

Prevention

Not all cases of pulmonary fibrosis can be prevented, especially when the cause is unknown. However, you can lower your risk by not smoking, avoiding exposure to harmful dusts and fumes, and managing any underlying health conditions carefully.

Vaccines

Staying up to date with flu, pneumonia, and COVID-19 vaccines is strongly recommended to protect your lungs from additional infections.

Screening programmes

There is no routine screening test for pulmonary fibrosis. However, if you have a strong family history or work in a high-risk occupation, your doctor may recommend regular lung function checks.

Complications

If left untreated

• Progressive breathing difficulty that can limit even simple activities
• Low oxygen levels in the blood, which may require long-term oxygen therapy
• Increased risk of lung infections or a sudden worsening of symptoms (called an exacerbation)
• Strain on the right side of the heart, which can lead to heart failure
• Respiratory failure, which occurs when the lungs cannot get enough oxygen into the blood

Long-term outlook

The course of pulmonary fibrosis varies greatly from person to person. Some people live with mild symptoms for many years, while others progress more quickly. Although it is a serious condition, there are treatments and support options that can slow progression and help you stay active and involved in the things you care about. Hope comes from the fact that researchers are constantly developing new therapies, and many people find strength through support networks and skilled healthcare teams.
