FCAAIA Notes: Weight loss and good physical conditioning are so important in virtually every aspect of health that we should not just concentrate on asthma. It is pretty clear that obesity contributes to diminished respiratory status with more shortness of breath and so on. My interpretation of the data are that at least some of that is because of other factors such as increased incidence of GE reflux, increased “work of breathing” because of the very thick and stiff chest wall, and overall de-conditioning resulting in worse exercise tolerance.
If you are overweight or obese, work hard to lose weight. Your ideal body mass index (BMI) should be 18.5-24.9. Curious? Continue reading “IS THERE A ROLE FOR WEIGHT LOSS IN OBESE PATIENTS WITH ASTHMA?”
FCAAIA Notes: Obesity is a risk factor for worse asthma control. There are some data indicating that asthma with obesity is in some ways qualitatively different than asthma in people of normal weight. Obesity adds increased work of breathing and a non-compliant or “stiff” chest wall (restrictive airway disease). It is also a risk for gastroesophageal reflux than can contribute to asthma and cause cough in and of itself.
No one ever claimed that losing weight is easy. But, if you are overweight (body mass index [BMI} 25-29.9) or obese (BMI ≥30) there are many health benefits to weight loss. To calculate your BMI: BMI= [weight in pounds/(height in inches)2]x703. Don’t cheat by underestimating your weight or overestimating your height!

FCAAIA Notes: Fructose is a sugar found in its natural form in fruits and vegetables. So, is this study saying women shouldn’t eat a lot of fruit during pregnancy? No, not at all. The title and the study from which it is derived are a perfect example of why we need to read all the information and not jump to conclusions because of a headline.
Fructose is commonly added to soft drinks and juice to sweeten the beverage. In truth, it was excessive ingestion of fructose infused processed refreshments Continue reading “MOM’S, KID’S FRUCTOSE INTAKE LINKED TO ASTHMA”
FCAAIA Notes: The relationship between obesity and asthma is complex for a variety of reasons. Many obese patients are short of breath merely because their chest wall is less compliant and does not expand with inhalation as easily as in patients of normal weight. Often, their shortness of breath is misdiagnosed and treated as asthma. Obese patients have often less well physically conditioned so have exercise induced symptoms unrelated to asthma. Finally, obesity predisposes to GE reflux, a common cause of cough and common trigger to asthma symptoms. So, weight loss can lead to symptom improvement even if the symptoms are not asthmatic.
Of course, obesity is a risk for numerous other chronic, dangerous and potentially life threatening problems. It doesn’t matter if you have asthma or not. If you are obese, talk to your primary care physician to discuss weight loss strategies. Continue reading “RISK OF ED VISITS, HOSPITALIZATIONS FOR ASTHMA DECREASE AFTER BARIATRIC SURGERY”
