Causes of Coughing in Humans
Causes of Coughing – Viral infections that cause cough can usually subside by itself. Coughing can be categorized into acute and chronic cough based on time.
Most coughs are caused by viral infections of the upper and lower respiratory tract.
Upper respiratory tract infections include colds, flu, laryngitis, sinusitis and whooping cough. This infection attacks the throat, throat, and sinuses.
While bronchitis and pneumonia are examples of viral infections in the lower respiratory tract, either in the lower respiratory tract itself or in the lungs.
In addition to infection, the cause of acute cough can also be triggered by a number of factors. Some of them are:
- Chronic diseases, such as asthma, Chronic Obstructive Pulmonary Disease (COPD), as well as chronic bronchitis.
- Allergic rhinitis or hay fever.
- Accidentally inhale cough triggers, such as dust or smoke.
Chronic or Long-term Cough
Although rare, cough may signal a more serious health condition. For example, tuberculosis, pulmonary embolism, lung cancer, or heart failure.
This type of cough is more commonly experienced by adults than with children. Some of the causes of prolonged cough in adults include:
- Drugs with a prescription, such as drugs used to treat hypertension or heart disease.
- Smoke. Coughing in smokers can also be a symptom of Chronic Obstructive Pulmonary Disease (COPD).
- Stomach acid disease due to irritation due to the rise of stomach acid.
- Long-term respiratory tract infections, eg chronic bronchitis.
- Chronic illness, such as asthma.
- Postnasal drip (mucus that trickles from the back of the nose to the throat caused by allergies such as rhinitis).
