Symptoms of Cystic Fibrosis
Symptoms of Cystic Fibrosis
What are the symptoms of cystic fibrosis?
Many children today are diagnosed with cystic fibrosis (CF) before they have any symptoms. Every state offers cystic fibrosis screening as part of their newborn screening programs. If a newborn has a positive result for cystic fibrosis, additional tests are done. Before screening programs existed, most children with CF were diagnosed after one of the following:
Respiratory symptoms such as cough, wheezing, or breathing difficulty
A thick and sticky first bowel movement of a baby that can block the small intestine (meconium ileus)
Not gaining weight as is normal after birth (failure to thrive)
The following are the most common symptoms for CF. Symptoms also may depend on when your child is diagnosed:
Salty tasting skin
Chronic respiratory symptoms like wheezing, cough, and thick material coughed up from the lungs (sputum) that is sometimes bloody
Lung infections
Poor weight gain and growth
Constipation
Greasy and bulky stools
Other health problems
These are other symptoms and health problems that may occur in some children with CF:
Sinus infection (sinusitis)
Nasal polyps or an abnormal growth out of the mucus membranes of the nose
Clubbing of fingers and toes. This is a condition marked by the widening and rounding of the tips of the fingers and toes due to lack of enough oxygen in the bloodstream.
Collapsed lung (pneumothorax), caused by air or gas leaking into the area around the lungs
Coughing up blood (hemoptysis)
Right-sided heart failure caused by long-term high blood pressure in the lung arteries (cor pulmonale).
Belly pain
Gas in the intestines
Part of the rectum sticks out through the anus (rectal prolapse)
Liver disease
Diabetes
Inflammation of the pancreas (pancreatitis). This organ creates many hormones and enzymes the body needs to work properly.
Gallstones
Congenital bilateral absence of the vas deferens in males
CF symptoms vary for each child. Infants born with CF usually show symptoms within the first year. But some children may not show symptoms until later in life. The following symptoms may indicate CF, and infants having these signs may be tested for CF:
Diarrhea that doesn’t go away
Bad-smelling stools
Greasy and bulky stools
Frequent episodes of wheezing
Frequent episodes of pneumonia
Persistent cough
Skin tastes very salty
Poor weight gain and growth
Chronic sinus infection
The symptoms of CF sometimes look like other conditions or health problems. Always see your child’s healthcare provider for a diagnosis.
