The Link Between Nutrition and Exercise in Cystic Fibrosis

Lungs aren't the only organs affected by the thick, sticky mucus that cystic fibrosis produces. The pancreas, an exocrine gland that normally secretes digestive enzymes necessary to absorb nutrients from food, can be coated with mucus as well. In fact, nearly 85% of CF patients demonstrate pancreatic insufficiency before age 10. This can lead to issues of malabsorption and malnutrition due to the body's inability to break down fats, carbohydrates and protein before they pass into the intestinal system.

Nutrition and Calories

In order to remedy this problem, many CF patients are prescribed digestive enzyme supplements to help the body better absorb the vitamins and minerals that are present in the diet. However, digestive enzymes are only part of the solution. A person with CF needs to incorporate more calories into their diet than other healthy people their same age. Important ways that you can help your child with CF grow healthy and strong include providing good overall nutrition along with extra fat and calories and prescribed enzymes

Caloric Intake* Ranges Based on Age Group and Activity²

1. Toddlers 1700 (low activity) 1950 (high activity)

2. Children 2300 (low activity) 3000 (high activity)

3. Teens 2000 (low activity) 4500 (high activity)

4. Adults 3000 (low activity) 4500 (high activity)

* Additional calories may be required during periods of illness or infection

It is important for everyone with CF to combine good nutrition and appropriate exercise. One of the challenges that await school-age children upon returning to the classroom is that eating habits may need to change. For example, a child who has been able to "graze" frequently during the day may have trouble adjusting to the pre-determined eating schedule set by the school or classroom.

More calories are needed to fulfill the dietary requirements of people with cystic fibrosis.
