Poor uptake of vitamin D from the diet because of malabsorption can lead to the bone disease osteoporosis in which weakened bones are more susceptible to fractures.
The main cause of infertility in men with CF is congenital absence of the vas deferens (which normally connects the testes to the ejaculatory ducts of the penis), but potentially also by other mechanisms such as causing no sperm, abnormally shaped sperm, and few sperm with poor motility.
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.
Another is infection with Mycobacterium avium complex, a group of bacteria related to tuberculosis, which can cause lung damage and does not respond to common antibiotics.
In the early stages, incessant coughing, copious phlegm production, and decreased ability to exercise are common.
Other signs include coughing up blood (hemoptysis), high blood pressure in the lung (pulmonary hypertension), heart failure, difficulties getting enough oxygen to the body (hypoxia), and respiratory failure requiring support with breathing masks, such as bilevel positive airway pressure machines or ventilators.
The most common infection involves bacterial strain mutation to form a biofilm-forming and sustaining mucoid strain on the lung epithelium, which can result in downstream mechanisms that progress the infection.
The liver fails to rid the blood of toxins and does not make important proteins, such as those responsible for blood clotting.
The pancreas contains the islets of Langerhans, which are responsible for making insulin, a hormone that helps regulate blood glucose.
Although most people have two working copies (alleles) of the CFTR gene, only one is needed to prevent cystic fibrosis.
