Here are some terms you may hear after being diagnosed with pulmonary fibrosis. Common pulmonary fibrosis terminology is listed in alphabetical order.

A

Alveolus, alveoli

Tiny air sacs in your lungs where oxygen leaves and enters the bloodstream.

Anti-fibrotic drugs

Drug treatments such as nintedanib and pirfenidone, which aim to slow down lung scarring and slow the rate at which the disease gets worse.

Autoimmune disease

Diseases such as rheumatoid arthritis and scleroderma, where your own immune system attacks your body and makes it inflamed. These can cause pulmonary fibrosis.

B

Breathlessness

One of the most common symptoms of pulmonary fibrosis. People who are breathless may also be described as hungry for air or short of breath.

F

Fibrosis

Where tissue becomes damaged and scarred, making it thicken and become stiffer. Pulmonary fibrosis (scarring in your lungs) makes it harder for you to breathe.

Forced vital capacity (FVC)

The total amount of air you breathe out during a breathing test. The lower your FVC, the more serious the disease is.

H

Hypersensitivity pneumonitis

Pulmonary fibrosis caused by an immune reaction to dusts breathed into the lungs.

I

Idiopathic

Of unknown cause

Idiopathic pulmonary fibrosis (IPF)

Pulmonary fibrosis of unknown cause. The most common type of pulmonary fibrosis.

Interstitial lung disease (ILD)

A group of diseases where the lungs are either inflamed or have scarring. Pulmonary fibrosis is a type of ILD. You may visit an ILD unit in a hospital.

ILD consultant

A senior doctor in a hospital who specialises in interstitial lung disease (ILD), such as pulmonary fibrosis.

ILD nurse

A nurse who specialises in interstitial lung disease (ILD). You may see an ILD nurse as a member of your medical team.

L

Lethargy

One of the most common symptoms of pulmonary fibrosis. Lethargy is also known as tiredness or fatigue.

O

Occupational therapy

A type of therapy to help you live with pulmonary fibrosis symptoms more easily. You might see an occupational therapist to help you manage exercise and everyday activities.

P

Palliative care

Care that aims to improve a patient’s quality of life. You can have palliative care at any stage of a disease, not just at the end of your life.

Progressive

Getting worse over time. Idiopathic pulmonary fibrosis (IPF) is a progressive disease.

Pulmonary

Relating to the lung

Pulmonary fibrosis

Diseases where there is lung scarring. Idiopathic pulmonary fibrosis (IPF) is the most common type.

Pulmonary hypertension

A lung condition where there is increased blood pressure within the arteries of the lungs. Pulmonary hypertension can be a complication of pulmonary fibrosis.

Pulmonologist

An American term for a doctor who specialises in all lung problems. Equivalent to a Respiratory consultant in the UK.

R

Respiratory consultant

A senior doctor who specialises in diseases affecting breathing.

S

Sarcoidosis

A disease where groups of inflamed cells form small lumps (granulomas) in the lungs or other tissues. Sometimes it leads to pulmonary fibrosis.

Scarring

Where tissue becomes damaged, making it thicken and become stiffer. Typically seen when a wound is healing. Scarring is often known as fibrosis.

T

TLco and DLco

One of the lung function tests, also known as ‘gas transfer’, indicating how well the alveoli can transfer gases (such as oxygen) from the air into the blood.
