Cystic fibrosis dating people with cystic fibrosis
In rare cases, cystic fibrosis can manifest itself as a coagulation disorder.Vitamin K is normally absorbed from breast milk, formula, and later, solid foods.Although most people have two working copies (alleles) of the CFTR gene, only one is needed to prevent cystic fibrosis.CF develops when neither allele can produce a functional CFTR protein.In addition to typical bacterial infections, people with CF more commonly develop other types of lung disease.Among these is allergic bronchopulmonary aspergillosis, in which the body's response to the common fungus Aspergillus fumigatus causes worsening of breathing problems.
Malabsorption leads to malnutrition and poor growth and development because of calorie loss.
Inflammation and infection cause injury and structural changes to the lungs, leading to a variety of symptoms.
In the early stages, incessant coughing, copious phlegm production, and decreased ability to exercise are common.
This absorption is impaired in some cystic fibrosis patients.
Young children are especially sensitive to vitamin K malabsorptive disorders because only a very small amount of vitamin K crosses the placenta, leaving the child with very low reserves and limited ability to absorb vitamin K from dietary sources after birth.
