Nutrition and cystic fibrosis related diabetes

Almost everyone with cystic fibrosis is unable to digest and absorb food so they have a low body mass index (BMI). Therefore most take creon tablets before each meal, to help break down food.

CF-related diabetes (CFRD) affects more than half of people with cystic fibrosis over the age of 30. Symptoms of this unique form of diabetes include an increase in thirst and urination caused by high blood sugar levels, excessive tiredness, weight loss and a decline in lung function.

As people with cystic fibrosis live longer, CFRD is becoming increasingly common.
