What causes a dry cough triggered by a rising sensation of gas in the throat, and what should be done about it?

Generally, a sensation of gas rising in the throat followed by dry cough may be caused by dietary irritation, emotional fluctuations, gastroesophageal reflux disease (GERD), allergic cough, or chronic pharyngitis. Patients can choose appropriate management approaches such as lifestyle adjustments, medication, or surgical treatment based on their specific condition. Detailed analysis is as follows:

1. Dietary irritation: Consuming spicy or hot foods, or drinking carbonated beverages, can irritate the mucous membranes of the throat and esophagus, triggering spasmodic dry cough. Adjust the diet by choosing mild, easily digestible foods, chewing thoroughly, and avoiding overeating.

2. Emotional fluctuations: Stress and anxiety may lead to sympathetic nervous system activation, causing contraction of throat muscles and resulting in sudden episodes of dry cough accompanied by a sensation of rising air. Practice deep breathing, meditation, or other relaxation techniques to regulate emotions, maintain mental calmness, and follow a regular sleep schedule to avoid excessive fatigue.

3. Gastroesophageal reflux disease (GERD): Stomach acid reflux can irritate the pharyngeal mucosa, leading to a sensation of a foreign body and persistent irritating dry cough. Under medical guidance, patients may take medications such as omeprazole enteric-coated capsules, domperidone tablets, or hydrotalcite chewable tablets, and should avoid eating within two hours before bedtime.

4. Allergic cough: Exposure to allergens such as pollen or dust mites can trigger an allergic reaction in the pharyngeal mucosa, resulting in paroxysmal dry cough. Under medical supervision, medications such as levocetirizine hydrochloride tablets, montelukast sodium chewable tablets, or budesonide inhalation aerosol may be used, and known allergens should be avoided.

5. Chronic pharyngitis: Long-term inflammation of the pharyngeal mucosa increases sensitivity, making it prone to dry cough upon exposure to gaseous irritants. Under medical advice, treatments such as Qinghou Liyan granules, watermelon frost lozenges, or Lanqin oral liquid may be taken. Avoid exposure to dust and irritating gases.

Daily care should focus on protecting the throat—drink plenty of warm water to keep mucous membranes moist and wear a mask outdoors to block irritants. Maintain moderate physical activity to strengthen overall health and follow regular meal times to support gastrointestinal health. If dry cough persists for more than two weeks, seek timely medical evaluation to identify the underlying cause.
