Patient's question:
Can eating too much sugar as a child cause asthma?Doctor's answer:
Bronchial asthma has the following causes:(1) Allergic factors: 30% to 40% of bronchial asthma patients can be identified with allergens. Dust mites, cat and dog dander, mold, pollen, milk, eggs, silkworm silk, feathers, moths, cotton, and fungi are all important allergens.
(2) Non-specific physical and chemical factors, such as inhaling smoke, dust, and the odors of vegetable oil, gasoline, or paint, as well as cold air, can stimulate the sensory nerve endings under the bronchial mucosa, reflexively causing vagal nerve excitement and coughing. This leads to bronchial smooth muscle spasm based on airway hyperresponsiveness.
(3) Microbial infections: Colds and upper respiratory infections are the most common triggers, especially during winter and spring or when the climate changes. Respiratory infections, particularly viral infections, are more likely to cause asthma attacks in children.
(4) Overexertion: Sudden, intense physical labor or prolonged strenuous exercise, as well as tense competitive sports, can trigger asthma.
(5) Psychological factors: Emotional fluctuations can serve as triggers. Anxiety, sadness, excessive excitement, or even laughter can lead to asthma attacks.
(6) Occupational factors: This involves a wide range, such as workers in pharmaceutical industries or chemical enterprises who are allergic to certain drugs or raw materials, and healthcare workers who are allergic to certain medications.
(7) Climate factors: Cold seasons can make people more susceptible to respiratory infections, or sudden weather changes or drops in air pressure can all trigger bronchial asthma attacks.
