Why is having a good diet important if you have cystic fibrosis?
Cystic fibrosis causes a build-up of mucus that blocks the ducts in the pancreas and means digestives juices containing enzymes do not reach the stomach and therefore food is not broken down properly. This pancreatic insufficiency affects about 90% of people with CF to varying degrees, and is managed with digestive enzyme replacements.
People with cystic fibrosis should have a balanced diet although many will require more energy (calories), to maintain a healthy body weight. For some people with CF it can be very difficult to maintain a healthy weight. Having CF can increase the body’s energy needs by 150-200% or even higher if lung function drops or if the body is fighting an infection. Feeding the body with these extra calories can be really challenging if an individual is feeling poorly, tired or has a poor appetite.
Dietary and nutritional needs will vary according to age, weight, height, symptoms, lung function and activity level. Specialist cystic fibrosis dietitians are part of every hospital CF team and they can advise on an individual’s requirements.
