Cystic fibrosis thickens mucus, digestive juice and sweat to cause serious damage to the lungs and digestive system, states Mayo Clinic. Cystic fibrosis is an inherited condition.
Wheezing, persistent cough, thick mucus, inflamed nasal passages and breathlessness are some respiratory symptoms of cystic fibrosis, explains Mayo Clinic. Grave constipation, poor growth, foul-smelling stool and intestinal blockage are some digestive symptoms of cystic fibrosis. Difficulty breathing requires immediate medical care. Medications, chest physical therapy, pulmonary rehabilitation and surgery treat symptoms of cystic fibrosis. Cystic fibrosis has no cure as of 2015, but genetic testing of both parents before having children can determine the risk of a child inheriting the condition.
