Could it be asthma? How to spot the symptoms.
Imagine the challenge of trying to breathe through a straw for minutes or hours on end. That's how breathing can sometimes feel for people who have asthma—a chronic lung disease that causes the airways to narrow, making it difficult to breathe.
More than 25 million Americans now live with asthma, and that number continues to rise. While the disease affects people of all ages, it most often starts in childhood. It's important to recognize the symptoms of asthma and to get medical help for it. People with asthma—both young and old—can lead normal, active lives. The key to doing so is learning how to manage the disease.
What are the signs?
Sometimes asthma symptoms are mild and go away on their own. But at other times, symptoms can get worse and trigger an asthma attack.
Common asthma symptoms include:
• Chest tightness.
• Shortness of breath.
Not all people with asthma have the same symptoms. And having these symptoms doesn't always mean someone has the disease. If you suspect you have asthma, see a doctor. He or she can use your medical history, a physical exam and a simple lung function test to determine whether you have the disease.

Common triggers include:
• Allergens, such as dust mites; animal dander; mold; and pollens from trees, grasses and flowers.
• Cigarette smoke, air pollution and certain chemicals.
• Respiratory infections.
• Physical activity.
If your doctor confirms that you do have asthma, he or she can help you identify your particular triggers and give you advice on how to avoid them.
There is no cure for asthma. But it can be successfully managed if you learn how to control your asthma, get ongoing care and watch for signs that the disease is getting worse.
Asthma is treated with two types of medicines:
• Quick-relief medications, which provide temporary relief from asthma symptoms.
• Long-term control medications, which are taken daily to control airway swelling.
It's important to follow your doctor's advice on the proper use of asthma medications. Most of the time you can treat asthma symptoms on your own. But if you have trouble walking or talking because you are out of breath or if you develop blue lips or fingernails, you need to seek immediat
