Obesity and asthma are positively correlated. Surveys have shown that obese children without a family history of allergies have a 52-60% increased risk of asthma compared to children of normal weight, and that the number of obese children with severe asthma attacks is twice as high as the number of those of normal weight. Researchers believe that obese asthmatics are more reluctant to participate in physical activity, which exacerbates weight gain. Obese people have higher airway stress than normal people, and are susceptible to irritation, increased airway pressure, and easy narrowing and closing of the airways, resulting in wheezing and shortness of breath. In addition, obese people often sleep with snoring and open-mouth whistling, these will contribute to the onset of asthma. In addition, the therapeutic effect of inhaled hormones in obese asthmatic children will be lower than in non-obese people.
