Final answer:
Dennis is likely suffering from asthma, a chronic respiratory condition causing inflamed and constricted airways, leading to symptoms like wheezing and difficulty breathing. He needs a medical evaluation to diagnose and manage the condition.
Step-by-step explanation:
Dennis's Health Condition
Dennis, a 12-year-old boy who experiences shortness of breath, wheezing, and sleeping difficulties, is most likely suffering from asthma. Asthma is a chronic illness affecting both children and adults, where the airways become inflamed and constricted, leading to breathing challenges. Symptoms typically include wheezing, chest tightness, shortness of breath, and coughing, particularly during the night and early morning. Asthma is triggered by factors such as allergies, exercise, weather conditions, and stress, and is not contagious. It can be managed with medications and by avoiding triggers such as smoke.
Dennis likely needs an assessment by a healthcare provider for a proper diagnosis and a treatment plan, possibly involving the use of an inhaler to relieve symptoms.
