What can be a complication of untreated cystic fibrosis?

  1. Sudden collapse of lung tissue

  2. Chronic lung infections

  3. Severe allergic reactions

  4. Increased risk of asthma

The correct answer is: Chronic lung infections

Untreated cystic fibrosis can lead to chronic lung infections due to the thick, sticky mucus it produces, which can obstruct airways and trap bacteria. This creates an environment that is ideal for infections to occur, leading to repeated episodes of pneumonia and bronchitis. Over time, chronic infections can cause significant lung damage, resulting in respiratory failure in severe cases. The importance of managing cystic fibrosis is to prevent this accumulation of mucus and subsequent infections, which can severely impair lung function and quality of life for the patient. This concept highlights the critical nature of early diagnosis and ongoing treatment in individuals with cystic fibrosis to mitigate such complications.
