Idopathic Pulmonary Fibrosis

What Is Idiopathic Pulmonary Fibrosis (IPF)?

• Idiopathic Pulmonary Fibrosis (IPF) is a chronic, progressive lung disease where lung tissue becomes thickened, stiff, and scarred (fibrosis) over time without a known cause (“idiopathic” means unknown cause). As the scarring worsens, it becomes harder for the lungs to work properly and supply the body with oxygen.

​

• While there's no cure for IPF, certain medications can slow disease progression, ease symptoms, and improve quality of life.

What Causes IPF?

The exact cause of IPF is unknown, but several risk factors may contribute:

• Risk Factors & Possible Triggers:

  • Genetic predisposition: Family history of lung disease

  • Environmental exposures: Dust, chemicals, and pollutants

  • Cigarette smoking: A known risk factor

  • Chronic viral infections: Epstein-Barr virus, hepatitis C

  • Gastroesophageal reflux disease (GERD): May cause micro-aspiration that irritates lungs

  • Age: Most people are diagnosed over age 50

  • Gender: More common in men

Health Condition Overview: Idiopathic Pulmonary Fibrosis

IPF is part of a group of diseases called interstitial lung diseases (ILDs) that cause scarring (fibrosis) in the lungs, making it hard to breathe and get enough oxygen. Unlike asthma or COPD, IPF is not caused by inflammation or narrowing but by irreversible scarring.

Symptoms of IPF

• Early Symptoms:

  • Chronic dry cough that doesn’t go away

  • Shortness of breath during activity (exertional dyspnea)

  • Fatigue and weakness

  • Weight loss

  • Clubbing of fingers or toes (widening and rounding of fingertips)

​

• Advanced Symptoms:

  • Trouble breathing even at rest

  • Bluish tint to lips or skin (due to low oxygen)

  • Frequent lung infections

  • Difficulty performing daily activities

Medications for IPF

The goal of IPF treatment is to slow the progression of the disease and reduce symptoms. While there is no cure, two FDA-approved medications help manage the condition:
 

1. Pirfenidone (Esbriet)

• Function: Slows scarring of lung tissue

• How it works: Reduces the activity of fibrosis-causing molecules

• Dosage: Taken orally (capsules/tablets), usually 3 times a day

• Common Side Effects:

  • Nausea, stomach upset

  • Loss of appetite and weight loss

  • Skin sensitivity to sunlight (photosensitivity)

  • Tiredness or dizziness
     

2. Nintedanib (Ofev)

• Function: Slows disease progression by targeting multiple pathways that cause scarring

• How it works: Blocks growth factors that lead to fibrosis

• Dosage: Taken orally, twice a day

• Common Side Effects:

  • Diarrhea (most common)

  • Nausea, vomiting

  • Liver enzyme elevation (requires regular blood tests)

  • Decreased appetite
     

Additional Supportive Treatments:

• Oxygen Therapy:

  • For those with low oxygen levels

  • Helps reduce breathlessness and fatigue
     

• Pulmonary Rehabilitation:

  • Exercise training, breathing techniques, and education

  • Improves stamina and overall well-being
    ​

• Cough Suppressants:

  • For dry, irritating coughs
    ​

• Lung Transplant:

  • Considered in advanced IPF cases for eligible patients

Diagnosis of IPF

Diagnosing IPF involves ruling out other causes of lung scarring and confirming the presence of fibrosis.

​

• Diagnostic Tools Include:

  • High-Resolution CT (HRCT): The gold standard for detecting lung scarring

  • Pulmonary Function Tests (PFTs): Measure how well your lungs work

  • Blood tests: Rule out autoimmune causes

  • Bronchoscopy or lung biopsy: May be needed in unclear cases

Prevention & Lifestyle Tips

While IPF cannot be prevented completely, certain steps can reduce risks or manage symptoms:

• Tips to Manage or Prevent Worsening:

  • Avoid smoking and secondhand smoke

  • Stay away from dust, mold, and chemicals

  • Use protective masks in dusty environments

  • Get vaccinated (flu, COVID-19, pneumonia) to prevent lung infections

  • Follow prescribed medications carefully

  • Eat a nutritious diet to maintain strength and weight

  • Stay active with gentle exercises, as advised by a doctor

Common Questions About IPF & Its Medications

1. Can IPF be cured?

• No. IPF is progressive and incurable, but medications like Pirfenidone and Nintedanib can slow progression and improve quality of life.

​

2. Are IPF medications safe for long-term use?

• Yes, but they require regular monitoring (especially liver function) due to potential side effects.

​

3. How long can someone live with IPF?

• The average survival is 3–5 years after diagnosis, but some patients live much longer with the right care.

​

4. Is oxygen therapy permanent?

• Not always at first. It's used as needed but may become continuous in advanced stages.

​

5. Should people with IPF avoid exercise?

• No. With doctor approval, gentle physical activity like walking can help maintain lung function and energy levels.

​

6. Are natural or herbal remedies effective for IPF?

• There is no proven natural cure, but a healthy lifestyle and complementary therapies (like breathing exercises) may help with symptom relief.
