What is the link between obesity and asthma?

Obesity is linked to asthma primarily because excess weight can lead to airway inflammation, which exacerbates asthma symptoms. When a person is obese, there is additional pressure on the lungs and airways, potentially causing mechanical issues with breathing. The accumulation of fat can also produce inflammatory substances that contribute to airway responsiveness and inflammation. This means that individuals who are overweight may experience more severe asthma symptoms and a higher likelihood of asthma attacks. The combination of these factors highlights how obesity can aggravate respiratory conditions, leading to a cycle where the asthma can worsen and potentially result in poorer overall lung function.
