What causes dry cough and nausea? Beware of five factors

If you experience dry cough and nausea, you should first identify the cause, which will be more helpful for treatment. Common factors that cause dry cough and nausea include respiratory tract diseases, environmental influences, allergic factors, etc. Only by finding the source can the body heal faster.

1. Upper respiratory tract lesions adjacent to the pharynx

For example, chronic inflammation of the nasal cavity, sinuses, and nasopharynx may irritate the pharyngeal mucosa due to the reflux of inflammatory secretions through the posterior nasal cavity to the pharynx; diseases such as chronic rhinitis, deviated nasal septum, chronic sinusitis, adenoids hypertrophy, snoring, or space-occupying lesions in the nasal cavity, sinuses, and nasopharynx affect nasal ventilation, causing long-term mouth breathing, causing long-term excessive dryness of the pharyngeal mucosa and leading to chronic pharyngitis; chronic inflammation of chronic tonsillitis can directly spread to the posterior pharyngeal wall, causing chronic pharyngitis; if oral inflammation is not controlled in time, it can also lead to chronic pharyngitis as the inflammation spreads.

2. Changes in climate and regional environment

Changes in temperature and humidity, poor air quality, stimulation from tobacco and alcohol, spicy and irritating foods, dust, harmful gases and radioactive exposure are also causes of chronic pharyngitis.

3. Occupational factors

People who use their voice extensively for a long time, such as teachers, singers, and those with susceptible physical conditions may also develop this disease.

4. Systemic factors

Such as anemia, indigestion, gastroesophageal reflux, heart disease (due to blood circulation disorders affecting the pharyngeal venous return causing local congestion in the pharynx), chronic bronchitis, bronchial asthma, rheumatism, liver and kidney diseases, etc., can also cause chronic pharyngitis. Endocrine disorders, autonomic nervous system disorders, infection with Bacillus rhinorrhoeae and diphtheroids, vitamin deficiency and immune dysfunction are all related to atrophic and dry pharyngitis.

5. Allergic factors

Inhaled allergens (including seasonal and perennial allergens), medications, chemical irritants in the workplace, and food allergens can all cause allergic pharyngitis.
