Question
Does eating too much sugar cause asthma in children?
Answer
The causes of asthma include the following: (1) Allergenic factors: Up to 30% to 40% of asthma patients can identify allergens. Dust mites, cat and dog dander, mold, pollen, milk, poultry eggs, silk, feathers, moths, cotton fibers, and fungi are all important allergens. (2) Non-specific physical and chemical factors, such as the inhalation of smoke, dust, and the smell of vegetable oil, gasoline, or paint, as well as cold air, can stimulate the sensory nerve endings under the bronchial mucosa, causing reflexive vagus nerve excitation and coughing. On the basis of high airway reactivity, this can lead to bronchospasm. (3) Microbial infections: Common triggers include colds and upper respiratory infections, which are more apparent during winter and spring or in changing weather conditions. Respiratory infections, especially viral infections, are more likely to trigger asthma attacks in children. (4) Overexertion: Sudden and intense physical labor or prolonged strenuous exercise, as well as competitive sports that are too intense, can trigger asthma. (5) Psychological factors: Emotional fluctuations can act as triggers. Worry, sadness, excessive excitement, even laughter, can all lead to asthma attacks. (6) Occupational factors: This involves a wide range of areas. For example, workers in pharmaceutical industries or chemical enterprises may be allergic to certain drugs or raw materials, and medical staff may be allergic to certain drugs. (7) Climatic factors: Such as being prone to respiratory infections due to catching a cold during the cold season or when the weather changes suddenly or the atmospheric pressure drops, which can trigger bronchial asthma attacks.
