It’s important to talk about your weight and nutritional goals with your CF Care Team to make sure you’re getting all the energy and nutrients you need to help keep you healthy. Below are some things to keep in mind as you’re talking with your care team about your nutrition.


People with CF need more calories

People with CF need more energy to breathe normally, fight lung infections, and compensate for poor digestion. That means they need more calories than people without CF of similar age and weight. In fact, people with CF generally need up to twice the amount of daily calories. A high-calorie, high-fat diet, with 40% of total calories from fat, is generally recommended.

CF makes it hard for your body to absorb certain vitamins

Certain vitamins, such as A, D, E, and K, need fat in order to be absorbed by your body. But your body may have trouble absorbing fats, which means you may need to take supplements to help.

Only your CF Care Team can give you advice about your disease and treatment, so remember to talk with them about any questions you have. Here are a few questions you can ask to get you started:

  • What is considered a healthy rate of weight gain? 
  • How many calories should I eat every day?
  • How can I add healthy calories to meals?
  • Should pancreatic enzyme supplements be added to my food?
  • Should I take vitamins?


Being active may also help manage your CF. It is important to discuss your exercise plans with your doctor and CF Care Team.

The effect of Pulmozyme (dornase alfa) on exercise tolerance has not been established in adults or children. Please see the accompanying full Pulmozyme Prescribing Information for additional Important Safety Information.


Here are a few things to discuss with your CF Care Team and your doctor before getting started:

  • Discuss exercises that may be fun for you, as well as safe
  • Set small, manageable goals for your exercise plan
  • Create a routine that you're excited about, and that gradually allows you to do more
  • Work with your CF Care Team to discuss signs that may mean it’s time to take a break from the action
