What to do if you have asthma and cough? What causes wheezing and coughing?

Cough and asthma are one of the common diseases in our daily life. Especially in today's increasingly serious air pollution, respiratory diseases bother us anytime and anywhere. So, what are the causes of coughing and wheezing?

1. Inhalation

Inhalants are divided into two types: specific and nonspecific. The former include dust mites, pollen, fungi, animal dander, etc.; non-specific inhalants include sulfuric acid, sulfur dioxide, chloramine, etc. Specific inhalants of occupational cough include toluene diisocyanate, phthalic anhydride, ethylenediamine, penicillin, protease, amylase, silk, animal dander or excrement, etc. In addition, non-specific ones include formaldehyde, formic acid, etc.

2. Infection

The development and onset of cough are associated with recurrent respiratory tract infections. Patients with cough may have specific IgE to bacteria, viruses, mycoplasma, etc., and inhalation of the corresponding antigens may induce coughing. After viral infection, the respiratory epithelium can be directly damaged, resulting in increased respiratory tract reactivity.

Some scholars believe that viral infection caused by interferon and IL-1 increases the release of histamine. During the breastfeeding period, especially respiratory viruses, respiratory syncytial virus infection, cough and asthma are one of the common diseases in our daily life. Especially in today's increasingly serious air pollution, respiratory diseases bother us anytime and anywhere.

3. Food

Cough attacks caused by diet are common in cough patients, especially infants and young children who are prone to food allergies, but this phenomenon gradually decreases with age. The most common foods that cause allergies are fish, shrimp, crab, eggs, milk, etc.

4. Climate change

Changes in air temperature, temperature, air pressure and/or air ions can induce coughing, so it is more common in cold seasons or when the climate changes from autumn to winter.

5. Mental factors

The patient's emotional excitement, nervousness, resentment, etc. can all trigger a coughing attack. It is generally believed that it is caused by cerebral cortex and vagus nerve reflexes or hyperventilation.

6. Exercise

About 70% to 80% of patients experience coughing after strenuous exercise, which is called exercise cough, or cough. Clinical manifestations include cough, chest tightness, shortness of breath, wheezing, and wheezing, which can be heard by auscultation. Some patients present with atypical asthma after exercise, but pulmonary function tests may reveal bronchospasm before and after exercise.
