Symptoms of COPD
Primary symptoms of COPD include:
Shortness of breath during exercise
Shortness of breath at rest
Chronic cough especially in the morning
Cough production of sputum
COPD often begins after a person has been smoking for 10 years. Symptoms are usually not noticeable, with the exception of a productive, chronic cough. Usually after age 40, shortness of breath occurs during exertion. Although it continues to worsen over time, it is often mistaken for a sign of aging and is usually dismissed.
All COPD patients have some degree of airway obstruction. While symptoms and severity vary over time, a gradual deterioration takes place over the course of four to five years. Repeated and increased productive coughing will begin to disable patients, who will eventually take longer to recover from the attacks, affecting the overall quality of life.
Symptoms of Asthma
Asthma signs and symptoms can range from mild to severe. You may have only occasional asthma episodes with mild, short-lived symptoms such as wheezing. In between episodes you may feel normal and have no difficulty breathing. Some people with asthma have chronic coughing and wheezing punctuated by severe asthma attacks.
Most asthma attacks are preceded by warning signs. Recognizing these warning signs and treating symptoms early can help prevent attacks or keep them from becoming worse.
Warning signs and symptoms of asthma in adults may include:
Increased shortness of breath or wheezing
Disturbed sleep caused by shortness of breath, coughing or wheezing
Chest tightness or pain
Increased need to use bronchodilators — medications that open up airways by relaxing the surrounding muscles
