High-Calorie Diet and Vitamin Supplementation for Cystic Fibrosis
cystic fibrosis who take digestive
enzymes can eat many of the same foods as anyone else.
But people with cystic fibrosis will generally need to eat more calories each
day, on average, than people who do not have the disease. Eating high-calorie,
nutritious foods is important for increasing or maintaining weight and
providing energy. Eating well can also strengthen the
immune system and the muscles used for breathing.
Consider trying any of the following:
Special nutritional drinks made for people who have chronic diseases or nutritional
deficiencies. These are available at grocery stores and pharmacies. Most of
these drinks are high in calories, protein, and fat, although they
are also available in low-fat, high-calorie forms. Ask your doctor or a
registered dietitian about these drinks before you use
Medium-chain triglycerides (MCT) oil.
MCT oil gives you additional fat and calories and is easy to digest without the
help of enzymes. Ask your doctor if MCT oil is right for you.
A high-fat diet. The body uses less oxygen to convert fat into
energy, which makes digesting fat easier on your lungs than digesting proteins
or carbohydrates. Fat also provides more calories than other foods do. People
who have cystic fibrosis need to eat more fat than people who do not have the
Vitamin supplements. Vitamins A, D,
E, and K are fat soluble, which means they can only be absorbed if you are
eating and digesting enough fat. Because most people who have cystic fibrosis
lack the enzymes that are needed to digest and absorb fat, they may not get
enough of these
vitamins unless they take supplements.
Most specialized cystic fibrosis treatment centers have
dietitians who will work with you and your doctor to
develop a plan for what kinds of foods and vitamins you need.
is important for people who have cystic fibrosis to keep track of their weight
at home. Losing weight can be a sign that they are not getting all the
nutrients they need.
If a person who has cystic fibrosis is
not able to get all the vitamins and nutrients his or her body needs to stay
healthy, a feeding tube may be needed.
