The effects of cystic fibrosis primarily include respiratory and digestive issues. These can lead to frequent lung infections, difficulty breathing, persistent coughing, and poor digestion and absorption of nutrients. Other possible effects may include skin disorders, such as sweat gland dysfunction, but they are less common and not as significant as the respiratory and digestive symptoms. Cystic fibrosis does not cause circulatory and cardiovascular diseases or the absence of pigment.
