What causes dry cough without phlegm? Three common triggers

Dry cough without sputum is a very common phenomenon. Most dry coughs are allergic coughs. The patient's own constitution and the environment he or she is in are factors that induce dry cough without sputum. Therefore, when talking about this, we must find the cause and prescribe the right medicine.

Reason 1: Clinically, most chronic dry coughs are allergic coughs, also known as cough variant asthma or allergic bronchitis.

Reason 2: The causes of allergic cough are complicated, but they mainly include two aspects, namely the constitution of patients with allergic cough and environmental factors. The patient's constitution includes subjective conditions such as "genetic quality", immune status, mental and psychological state, endocrine and health status. Different patients have different conditions and need to be treated differently.

Reason three: Environmental factors including various allergens, irritating gases, viral infections, residential areas, living conditions, occupational factors, climate, medications, exercise (hyperventilation), food and food additives, eating habits, social factors and even economic conditions may be more important causes of the occurrence and development of allergic cough. The increasing trend in the incidence of allergic cough is also related to the susceptibility caused by the patient's allergic constitution and environmental factors.

Precautions

Actively improve the living environment, avoid allergens, open windows frequently for ventilation; pay attention to keeping warm and avoiding heat. Try not to eat spicy food, eat more vegetables and fruits, and avoid smoking and drinking.
