The association between the two conditions can be striking — several studies have shown that obese children and teenagers were twice as likely to have asthma as children at a healthier body weight. The response may depend on how it relates to additional phenotypical factors. These patients tend to be older, female, may not be respond as well to steroids, and have asthma less related to allergies. This article has been cited by other articles in PMC. More Michiganders are obese than were 10 years ago- who is obese? The exact mechanisms remain elusive and are probably multifactorial, stemming from mechanical alterations of the airways and lung parenchyma, to systemic and airway inflammatory and metabolic dysregulation that adversely influences lung function and or response to therapy.
Hospitalization and medications were found to be the most important cost driver of direct costs. So what does this mean for you and your health?
In fact, the link between asthma and obesity may now be recognized too much — a study published in the medical journal CHEST found that obese patients are at risk of being incorrectly diagnosed with asthma, due to the similarity of symptoms, such as breathlessness.
However, clinical characteristics associated with the highest BMI cluster that have been consistently described across studies include having late onset asthma, lower exhaled nitric oxide eNO levels, less airway eosinophils, and reduced atopy [ 8 — 10 ].
Asthma control assessments are based on how often symptoms, such as shortness of breath and inability to take part in physical activity, happen, and how severe the symptoms are.

Obesity and asthma
Mainstream clinical practice has yet to adopt aggressive management of obesity as a modifiable risk factor in asthma care, as is the case with a risk factor like tobacco or allergen exposure. Obesity is also linked to more frequent and severe respiratory symptoms. Extra weight increases the risk of having asthma and having more severe, difficult to control asthma. For children, overweight is defined as a BMI between the 85th and 94th percentile for age and gender, and obese is defined at a BMI at or above the 95th percentile for age and gender. This is not just a problem for adults of course, it's also a problem for children: around 21 percent of kids between the ages of 12 and 19 years old are also dealing with obesity. Early onset allergic asthma is characterized by TH2 driven lymphocytic inflammation with increases in cytokines such as IL-4 and IL-5 that promote airway eosinophilia and IL leading to mucus hypersecretion. Another study of more than 1, people found that obese adults with asthma are almost five times more likely than non-obese asthmatics to be hospitalized due to asthma.

In addition to being hospitalized more frequently due to their asthma, obese asthmatics have also been found to experience a poorer quality of life than asthmatics that aren't obese. In the study, about one-third of obese patients were misclassified with asthma. It's not entirely clear why carrying extra weight should cause asthma. Studies in immunology and molecular biology have resulted in an extensive evaluation of inflammatory cells and mediators involved in the pathophysiology of asthma.
The Latest in Asthma. Despite the availability of effective preventive therapy, costs associated with asthma are increasing. Keywords: Asthma, obesity, primary care, phenotypes Introduction Asthma prevalence Asthma is classically described as reversible inflammation of airways, characterized by recurrent attacks of shortness of breath, cough, and wheeze, affecting people of all ages.
Increasing weight gain can have profound implications on lung physiology, including the development of restriction from greater adiposity around the chest wall and abdomen.
