What are the common signs and symptoms of cystic fibrosis?

Cystic fibrosis is a genetic disorder that affects the respiratory and digestive systems of individuals. Common signs and symptoms of cystic fibrosis include persistent coughing, wheezing, chest pain, shortness of breath, poor growth, salty-tasting skin, and frequent lung infections. In addition, individuals with cystic fibrosis may also have digestive issues such as greasy, bulky stools, constipation, bloating, poor appetite, and weight loss.

In infants and young children, the most common signs of cystic fibrosis are failure to gain weight and grow as expected, frequent respiratory infections, and salty-tasting skin. As the disease progresses, patients may experience more severe symptoms such as persistent coughing, wheezing, and chest pain. They may also experience frequent lung infections, shortness of breath, and clubbing of the fingertips. Other signs and symptoms include greasy, bulky stools, constipation, bloating, poor appetite, and weight loss.

Cystic fibrosis can also affect other organs such as the pancreas and liver, resulting in additional signs and symptoms. In some cases, patients may experience a buildup of thick, sticky mucus in their pancreas which can lead to abdominal pain, nausea, and vomiting. In addition, cystic fibrosis can cause liver dysfunction, resulting in jaundice, dark urine, and light-colored stools. Individuals with cystic fibrosis may also be at an increased risk for developing diabetes.
