What are the common symptoms of a child with cystic fibrosis?

The common symptoms of a child with cystic fibrosis include frequent lung infections, difficulty gaining weight, and salty skin. Cystic fibrosis is a genetic disorder that affects the lungs and digestive system, leading to the production of thick, sticky mucus. This mucus can block airways and create an environment conducive to bacterial infections, which is why frequent lung infections are a hallmark symptom.

Additionally, children with cystic fibrosis often struggle with malnutrition and difficulty gaining weight because the thick mucus can obstruct the pancreas, preventing digestive enzymes from reaching the intestines. This impairment affects nutrient absorption, resulting in poor growth and weight gain despite a high-calorie intake.

The symptom of salty skin arises due to abnormal salt handling in the sweat glands. Individuals with cystic fibrosis typically excrete more salt in their sweat than those without the condition, which can often be noticeable when a child's skin tastes salty.

This combination of symptoms helps to identify cystic fibrosis and underscores the importance of early diagnosis and management for better health outcomes.
