Question

What are the effects of cystic fibrosis?

options:

circulatory and cardiovascular diseases

respiratory and digestive issues

absence of pigment

skin disorders

Answer 1

The effects of cystic fibrosis primarily involve respiratory and digestive issues. This genetic disorder affects the production and function of a protein called cystic fibrosis transmembrane conductance regulator (CFTR), leading to the buildup of thick, sticky mucus in various organs.

Respiratory effects: The thick mucus can obstruct the airways, making breathing difficult and leading to frequent lung infections, such as pneumonia and bronchitis. Over time, this can cause chronic lung damage and decreased lung function.

Digestive effects: The mucus can also block the ducts in the pancreas, preventing the release of digestive enzymes. This results in poor nutrient absorption and malnutrition. Cystic fibrosis can also lead to liver disease and gallstones.

Additionally, people with cystic fibrosis may experience other effects such as infertility in males (due to obstruction of the sperm ducts), delayed growth and development, osteoporosis, diabetes, and increased sweat salt levels (which can lead to dehydration and electrolyte imbalances).

Cystic fibrosis does not cause absence of pigment (albinism) or skin disorders as a direct effect.
