Breathing difficulties refer to challenges in getting enough air into the lungs, which can lead to feelings of shortness of breath or discomfort. Common causes include asthma, chronic obstructive pulmonary disease (COPD), and allergies. These conditions can affect the airways, making it harder to breathe. Symptoms of breathing difficulties may include wheezing, coughing, or a tight feeling in the chest. It is important to seek medical attention if breathing problems are severe or sudden, as they can indicate serious health issues. Treatments often involve medications, lifestyle changes, or therapies to improve lung function.
