Enzymes in cystic fibrosis
Digestive enzymes are made in the pancreas. The fat, protein and carbohydrate in food is broken down by the enzymes to release nutrients. In cystic fibrosis (CF) sticky mucus blocks the passages from the pancreas to the small intestine which stops the enzymes working, so the food cannot be digested or absorbed by the body. This is called malabsorption and causes loose or oily stools, wind, stomach ache and poor weight gain.
How do enzymes work in CF?
There are several brands of enzymes which come in a capsule for example, Creon® and Nutrizym® Beads inside the capsule contain digestive enzymes. The outer capsule dissolves in the stomach. The beads then move along into the small intestine where the coating dissolves releasing the enzymes. Food is then broken down and the nutrients are absorbed by the body.
When should enzymes be taken?
All food and drinks containing fat, including nutritional supplements, require enzymes. Enzymes need to be in the stomach at the same time as food. Enzymes should be taken at the start of a meal or snack. If you are unsure how much you will eat or the meal has several courses, the dose can be split If you forget to take enzymes at the start of a meal, it is not too late to take them at the end of the meal.
