Cough variant asthma symptoms
A cough caused by CVA lasts for many weeks, is dry, and does not make you produce mucus or phlegm.
Between 30% and 40% of people with a CVA cough will develop other asthma symptoms, according to a review of medical studies from 2011. Therefore treating a CVA cough can reduce the chances of developing more severe asthma symptoms such as difficulty breathing.
There can be some other, potentially serious causes of a cough, so you should contact your doctor urgently if you have a cough that persists for a few weeks. They will ask you questions and examine you to check for the cause of your symptoms.
Can a CVA cough trigger an asthma attack?
An asthma attack occurs when asthma symptoms suddenly get worse and using a reliever inhaler does not help. Symptoms can include wheezing, breathlessness, coughing, or a tight chest. If someone has an asthma attack, their breathing gets faster, and they can get too breathless to speak, eat, or sleep.
There are many triggers for an asthma attack, including allergies, infections, stress, smoke, pollution, changes in weather, exercise and certain medicines.
A CVA cough does not trigger an asthma attack, but it does mean you are more likely to develop other symptoms of asthma and have an asthma attack. This is because a CVA cough can lead to inflamed airways, which can cause other asthma symptoms.
