Why do people with cystic fibrosis’ need to take vitamins?

Many people with cystic fibrosis have problems when they eat food, making it hard for their intestines to soak up nutrients, especially fat. To help with this enzymes are taken with meals and snacks.

Even someone takes enzymes they can still lose fat in their stool. If they are losing fat their stool. If they are losing fat then they are probably also losing vitamins. If you don’t take your vitamins, over time, you may develop low levels in your blood. This is known as vitamin deficiency.

Vitamin A

Vitamin A has many important roles in the body. It helps you see at night and lets your eyes adjust when you move from a dark place to a bright place .If you have a vitamin A deficiency then   your eyes may not be able to get used to changes in light. There have been people with CF who have reported having this problem. If you think this is a problem. If you think this is a problem speak to your CF doctor.

Vitamin A also helps make skin and helps fight infection when you get sick. During childhood it helps you   grow. It is found in eggs, liver, tomatoes, milk and some fruits & vegetables. For people with CF, food sources are not enough to prevent vitamin A deficiency. Therefore a vitamin supplement is usually recommended.

Vitamin D

Vitamin D comes from two sources. It is made by the skin when it is exposed to sunlight, and it is found in the foods we eat. It helps your body absorb calcium, and helps move   calcium from your blood to your bones. Without enough vitamin D your bones can weaken and the chances of break in a bone become greater. While foods such as eggs and cereals contain vitamin D, the main source is milk. A vitamin supplement is usually recommended to make sure you get enough every day.

Vitamin E

Vitamin E has become very popular because of its role as an antioxidant. As you grow your body goes through many changes. As your body changes it produces harmful products that can destroy your healthy cells. Vitamin E helps get rid of these harmful products and this is why it is called an antioxidant. A deficiency of vitamin E can affect your body’s ability to protect itself when you get sick. For people with cystic fibrosis this may affect their lungs and their ability to breath. Foods that contain vitamin E include plant oils, margarines, and some fruits & vegetables. Diet alone cannot prevent a vitamin E deficiency in people with CF, therefore a supplement is usually recommended.

Vitamin K

Most of the vitamin K we need comes from our diet. It is found   in green vegetables, plant oils, and margarine. We also have healthy bacteria in our intestines that produce vitamin K. Even though the bacteria in your intestine is healthy, it can be destroyed by the antibiotics you may take for a lung infection .This can affect the amount of vitamin K you get on a daily basis. Vitamins K is very important because   it helps your blood clot. When you cut yourself, the time it takes for your cut to stop bleeding is affected by how much vitamin K you have in your body. The longer it takes to ‘clot’ the less   vitamin K you may have Vitamin K is also important for proper bone growth in children.
