Asthma is a chronic disease that causes your airways to be inflamed. The most common symptoms of asthma are coughing, shortness of breath, wheezing and chest tightness. But there are other diseases that can have the same symptoms of asthma. For your doctor to make the right diagnosis, it is important to know if your airways are inflamed.
If you are on a treatment plan for asthma but the treatment doesn’t seem to be working, you might not have asthma. Or you may need a different type of asthma medicine. If you’ve been misdiagnosed, you might be trying to treat a condition you don’t have – and at the same time possibly ignoring a condition you really have.

To understand asthma , a chronic disease that causes your airways to become inflamed, it helps to first know how your airways work. Watch on YouTube How Do Normal Airways Work? When we breathe in, air moves through our airways – from our nose or mouth, down a large hollow tube in the front of the neck called a windpipe or trachea – and into our lungs. The trachea divides into two tubes called bronchial [bron-KEE-uhl] tubes in the lungs. They look like upside-down trees. As the bronchial...
While I know that I am in the tiny percentage of the population who has a strong negative reaction to the Methacholine Challenge test, I want to offer one caveat. About six years ago, I had chronic cough and my doctor thought I might have asthma so he had me take the Methacholine Challenge test.
