What Is Bronchitis?
Bronchitis is a disease that causes the mucus membrane in the lung’s bronchial passages to become inflamed, resulting in coughing spells.* Sometimes, these coughing spells can be accompanied by breathlessness or phlegm.* If the disease lasts from 1-3 weeks it is classed as acute.* If it lasts at least 3 months for 2 years in a row, it is classed as chronic.*
Symptoms include a frequent cough that produces mucus, a wheezing sound when breathing, a lack of energy and sometimes a fever.* You should consult a doctor in particular if you have a fever, a cough that lasts more than 2-3 weeks, if your mucus includes blood or is thick or colored, or if you have chest pain, wheezing or any difficulty breathing.* These could be signs of other diseases, so it is worth getting a proper diagnosis.*
What Causes Bronchitis?
In most cases, the upper respiratory infection is caused by a virus, like the common cold, and results in acute bronchitis, but sometimes it is caused by bacteria.* Chronic bronchitis is normally caused by smoking or other industrial pollutants, and smoking can also make acute bronchitis worse.* Smoking and chronic bronchitis can develop into COPD (chronic obstructive pulmonary disease).*
