Asthma is a respiratory disease which causes chronic inflammation of the bronchial, which will eventually cause it to be permanently constricted. Breathing becomes more difficult.

Typical asthma symptoms are a constant dry and tickly cough, coughing at night, shortness of breath and wheezing, gasping noises when exhaling. Other common symptoms are breathlessness or tightness in the chest. Possible triggers of the disease are genetic factors and common allergens such as dust mites, infections of the respiratory system in early childhood and the inhalation of chemical fumes. Factors which aggravate asthma are dust, ozone, strong smells, smoke, fumes, colds and strong emotional reactions like anger, fear or joy.

Asthma should always be treated by a doctor. The patient can further decrease the symptoms by avoiding the asthma triggers.
