CF is a genetic, chronic disease. It affects the lungs and digestive system. A defective gene and its protein product cause the body to produce thicker and stickier mucus than normal.
The mucus:
- Clogs the lungs and leads to life-threatening lung infections
- Blocks the pancreas and stops natural enzymes from helping the body break down and absorb food
When the disease was first identified, children often died young. As research and treatments have advanced, people with CF are living longer.
Symptoms of CF
People with CF can have a variety of symptoms, including:
- Very salty-tasting skin
- Persistent coughing, at times with phlegm
- Frequent lung infections
- Wheezing or shortness of breath
- Poor growth or lack of weight gain despite a good appetite
- Frequent, greasy, bulky stools or difficulty in bowel movements
Quality and outcomes
Gaining weight and growing at a normal rate can be hard for kids with CF. They usually have better lung function if their BMI percentile is higher. BMI is a measure of a person's size based on their weight and height. If the number is too high or too low, it may cause health problems.
