Cystic fibrosis is a severe genetic disorder that can be fatal if not managed correctly. This disease causes the body's secretions, such as lung mucus, digestive juices, sweat, and reproductive fluids, to become thick and sticky. This article delves into the symptoms of cystic fibrosis, providing a comprehensive understanding of this life-threatening condition.
Cystic fibrosis can cause severe complications in the respiratory system. The thickening of lung mucus can lead to blockages in the lungs and airways, causing the patient to cough up thick sputum. This can also result in shortness of breath, wheezing, and the growth of polyps in the nasal passages. Furthermore, the frequency of sinus infections, chest infections, pneumonia, and bronchitis can significantly increase.
The digestive system is also heavily impacted by cystic fibrosis. The thickening of digestive juices can block the ducts from the pancreas and liver, preventing these juices from reaching the intestines. This can result in the inability to digest fats and proteins, leading to bulky, greasy, and foul-smelling stool. Despite having an excessive appetite, patients may be undernourished and underweight due to improper digestion and absorption of food. A trypsin test can be used to determine if sufficient enzymes from the pancreas are available for digestion.
One of the unique symptoms of cystic fibrosis is excessively salty sweat. This can be detected through a sweat test, where an odorless chemical is applied to a small area of the skin on the arm. This area is then stimulated with an electric current to produce sweat. In a healthy individual, the sweat should contain about 40 mmol/l of salt. However, a salt concentration above 60 mmol/l in a sweat test can confirm a diagnosis of cystic fibrosis.
Cystic fibrosis can also affect the reproductive system. The duct that connects the testes and vas deferens may get blocked in patients with cystic fibrosis, leading to sterility in most cases.
While there is no permanent cure for cystic fibrosis, treatment focuses on managing symptoms and improving quality of life. Bronchodilators and mechanical vibrators can help keep the lungs and airways clear. Enzyme and vitamin supplements can help maintain near-normal digestive function. With proper lifestyle management, individuals with cystic fibrosis in the United States are living into their 30s and 40s.
