Cystic fibrosis is a genetic condition marked by the accumulation of thick, sticky mucus, which can harm many internal organs. The respiratory system's gradual deterioration and persistent digestive system issues are the disorder's most typical signs and symptoms. Consult your doctor if you experience new or worsening symptoms, such as more mucus than usual or a change in the mucus color, lack of energy, weight loss, or severe constipation. You must also consult your doctor for testing if you or your child has symptoms of cystic fibrosis
