Idiopathic pulmonary fibrosis: what you need to know

Idiopathic pulmonary fibrosis (IPF) is a lung disease that causes scarring (fibrosis) in the lungs without a known cause. The scarring makes it harder to move oxygen into your blood, so you may feel short of breath and tired more quickly than before. Many people notice a dry cough, trouble with everyday tasks, or swollen fingertips (clubbing). The average life expectancy after diagnosis often ranges from about 3 to 5 years, but treatments and care plans can slow the decline and improve quality of life.

How doctors find IPF

If you or your doctor suspect IPF, expect a few key tests. A high-resolution CT scan of the chest looks for typical patterns of scarring. Pulmonary function tests measure lung capacity and how well your lungs move oxygen. Blood tests can rule out other causes and autoimmune issues. Sometimes doctors use bronchoscopy or a surgical lung biopsy when the diagnosis is unclear. Getting to a lung specialist (pulmonologist) experienced with fibrotic lung disease makes a big difference.

Treatment options that matter

Two antifibrotic drugs—pirfenidone and nintedanib—are the main medicines shown to slow lung function decline. They don’t cure IPF, but they can reduce the speed of progression. Oxygen therapy helps when blood oxygen drops, and pulmonary rehabilitation teaches breathing techniques, exercise plans, and ways to conserve energy. Vaccines (flu, pneumonia, COVID) lower infection risk, which can cause sudden worsening. For eligible patients, lung transplant can be life-saving; early referral to a transplant center is important.

Other parts of care include managing symptoms (cough, breathlessness), treating acid reflux if present, and addressing heart or sleep problems that often coexist. Palliative care teams can help with symptom control and advance planning even early in the disease. Clinical trials may offer access to new drugs—ask your pulmonologist what trials might fit your case.

Daily life tips: plan activity breaks, use breathing pacing (slow, pursed-lip breaths), keep a rescue plan for flare-ups, and avoid smoking and air pollutants. Stay active with guidance from rehab teams; even light exercise helps maintain function and mood. Keep immunizations up to date and treat infections quickly—lung infections are a common cause of rapid decline.

When to call your doctor: new or worsening breathlessness, new chest pain, fever, sudden weight loss, or confusion. These could signal infection, a flare, or complications that need urgent care.
