Thank Ms. Sue
Cystic fibrosis (CF) is a genetic disorder that primarily affects the lungs, but it also affects other organs, including the digestive system. CF is caused by a defective gene called the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which results in the production of thick, sticky mucus that can clog the airways and various ducts in the body.
In the case of the digestive system, CF affects the pancreas, liver, and intestines. Normally, the pancreas produces digestive enzymes that help break down and absorb nutrients from the food we eat. However, in people with CF, the thick mucus blocks the ducts in the pancreas, preventing these enzymes from reaching the intestines. As a result, the body cannot properly digest and absorb fats and proteins, leading to malnutrition and poor growth.
Additionally, the thick mucus can obstruct the bile ducts in the liver, causing liver disease. It can also affect the small intestine's ability to absorb nutrients, leading to deficiencies in fat-soluble vitamins like A, D, E, and K.
The digestive symptoms of CF can include malabsorption of nutrients, poor weight gain, greasy and bulky stools, and abdominal pain. These symptoms vary among individuals and can range from mild to severe.
To diagnose CF, genetic testing is usually performed to identify mutations in the CFTR gene. A sweat test may also be conducted to measure the concentration of salt in the sweat, as people with CF usually have higher levels of salt.
It's important to note that cystic fibrosis is a complex condition with various manifestations, and individuals with CF require ongoing medical care and management from a specialized healthcare team.
