Bronchitis

The respiratory disorder known as bronchitis results from inflammation of the bronchial tubes—which supply air to and from the lungs. Symptoms including constant coughing, mucus (sputum), chest discomfort, dyspnoea, and slight fever follow from this inflammation. Two basic forms of the disorder are acute and chronic bronchitis.
Usually stemming from viral infections, acute bronchitis commonly follows a cold or respiratory infection. Usually lasting a few days to several weeks, it resolves without any aftereffect. Conversely, a more severe, long-term illness usually brought on by smoking or extended exposure to irritants like dust, fumes, or air pollution is chronic bronchitis. Chronic bronchitis is one of the disorders included in Chronic Obstructive Pulmonary Disease (COPD).
Clinical symptoms, physical examination, and occasionally sputum testing or chest X-rays help to rule out other illnesses, including pneumonia, in the diagnosis. The type of bronchitis affects the treatment; acute cases are treated with rest, hydration, and symptomatic alleviation; chronic bronchitis may call for bronchodilators, corticosteroids, and lifestyle changes including smoking cessation.
Avoiding smoking, keeping excellent hygiene, and getting vaccinated against flu and pneumonia will help lower the risk of bronchitis by itself.
