Tuberculosis and Asthma |Similarities |Differences

Note: Bronchitis is almost synonymous with tuberculosis and could almost be used interchangeably

Although the symptoms of asthma and bronchitis are identical, the causes are not. The airways become irritated in both asthma and bronchitis. As a result, they puff up and make it difficult for air to enter the lungs. The organs and tissues receive less oxygen as a result. Shortness of breath, coughing, and chest constriction indicate a lack of oxygen.

Bronchitis is caused by viruses or elements in the environment, such as cigarette smoke and pollution. Asthma is caused by genetic alterations and environmental stimuli such as pollen and dust.

Sputum tests: The doctor will take a sample of the mucus you cough up from your lungs. Your sputum is examined for bacteria to determine if you have an infection.

A methacholine challenge or bronchoprovocation test may be performed if your doctor suspects you have asthma.

Asthma is associated with inflammation-related cells, whereas bronchitis is related to infection-fighting cells.

Asthmatic bronchitis symptoms
