Bronchitis Symptoms and Causes

What is bronchitis?

In bronchitis, the airways between the trachea (bronchial tubes) or between the mouth and nose, and lungs are swollen. In particular, in bronchitis, there is inflammation of the lining of the bronchial tubes (bronchial tubes). People with bronchitis have a reduced ability to take air and oxygen to the lungs.

This inflammation can be caused by viruses, bacteria, smoking or chemical pollution, or breathing in the dust. When the tissue cells of the lining of the respiratory tubes become more stimulating than a certain amount, the tiny hairs (cilia) inside them, which usually block the contaminants, stop working, causing the respiratory tubes to fill with mucus. Become more stimulating. People with bronchitis often have a thick mucus cough that may fade in color. About 90% of people seek medical advice for bronchitis.

Causes of bronchitis:

Some form of lung infection usually causes acute bronchitis. 90% of lung infections are viral. Long and frequent bronchitis attacks can irritate and weaken your bronchial airways due to chronic bronchitis. Industrial pollutants also contribute to developing bronchitis. People working in coal mines, grain handling industries, and food molders are more prone to develop chronic bronchitis. This is due to continuous exposure to smoke and dust. The major causes of bronchitis include cigarette smoking, exposure to high levels of sulfur dioxide, and exposure to other pollutants in the atmosphere.

Symptoms of bronchitis:

Cough (most common symptom)

Mucus formation (clear, yellow, green, or even blood)

Nausea, vomiting, and diarrhea (rare).
