What triggers asthma?

What triggers asthma?

When you have asthma, the mucus membranes of your respiratory tract swell, and at the same time you will have an increased production of mucus.  It is common for the asthma symptoms to deteriorate from, for example, infections of the respiratory tract, exercise, allergies and tobacco smoke.

Tobacco smoke has a tendency to trigger asthma, and causes people to lose control of their asthma.Parents who smoke is the single most common cause of the increase of asthma symptoms in small children. A dusty environment and strong smells may also be asthma triggers.

An asthmatic person who suffers from a viral infection will not just experience a cough, runny nose, sore throat and other cold symptoms. The viral infection can also cause the mucus production to increase and the airways to contract, making it difficult to breathe. During periods of infection, that is, during autumn and early spring, it is important to take extra care of yourself if you have asthma.

Asthma left untreated for a long time can cause chronic deterioration of lung function and reduced quality of life. If you suspect that you have asthma you should contact a doctor for an asthma diagnosis and treatment.
