What are the most common complications of cystic fibrosis?

The most common complications of cystic fibrosis (CF) are lung infections, nutritional deficiencies, and liver problems. Lung infections are the most common complication of CF, with bacteria such as Pseudomonas aeruginosa and Staphylococcus aureus being the most commonly found. These bacteria are highly resistant to antibiotics and can cause a worsening of the symptoms of CF, leading to a decrease in quality of life and an increased risk of death.

Nutritional deficiencies are also common in CF patients, due to difficulty in absorbing essential nutrients from the small intestine. This can lead to malnutrition, weight loss, and a decreased quality of life. Patients may need to take special supplements to ensure they get enough essential nutrients.

Finally, liver problems are a common complication of CF. This may be due to the increased pressure of the pancreas on the liver, leading to a build-up of bile in the liver. This can cause inflammation, scarring, and even cirrhosis. Treatments may include dietary changes, medications, and in some cases, surgery.
