Obesity has been rapidly increasing in prevalence over the past two decades—in children as well as in adults. Although obesity is a recognized risk factor for type 2 diabetes, hypertension, atherosclerosis, and some forms of cancer, new evidence suggests that obesity may also contribute to or even cause asthma.

Obese patients with severe asthma account for 75% of emergency department visits for asthma. A new study shows that obese adults with asthma are more likely than normal weight asthma suffers to have severe and persistent symptoms, and when obese asthma patients lose weight, there is a notable decrease in asthma symptoms and severity.

Obesity affects the anatomy of both the lungs and airways. Excess mass in the abdomen and chest put pressure on the lungs and the airways restricting the flow of air.

The impact can actually be life altering for children because that extra mass can affect lung growth, resulting in smaller lungs and reduced pulmonary function.

Another possible correlation is that obese individuals breathe at higher frequencies—but with smaller breaths—compared with non-obese individuals. As a result, the muscles around the airway are overworked and over stressed.

With every new study that emerges about the impacts of obesity, it becomes more clear that we have to take a firm stand against obesity.

Obesity not only puts people at risk for a number of chronic conditions but may also increase the likelihood of dying in a car crash. In general, car crashes are the most common cause of injury-related death for those ages 3 to 33. New studies show how body weight plays into this statistic.

Results of a recent study show that moderately obese individuals, those with a body mass index between 35 and 39, have a 21-percent higher risk of dying during a severe car crash compared with normal-weight individuals. Morbidly obese individuals, those with a BMI of 40 and above, have a 56-percent higher risk.

The results suggest that having a larger stomach puts an individual too close to the steering wheel, and therefore can boost the risk of mortality because the body has less time to slow down before hitting the steering column after impact.

To add to the danger for obese individuals, they are also more likely to have serious illnesses, including cardiovascular disease and diabetes, and are more likely to have complications during surgery, which may contribute to their higher risk of death after a crash.

Some are now considering whether car manufacturers should consider redesigning their vehicles co protect the one-third of obese Americans from injury during car crashes. It may be as simple as allowing the driver’s seat to push further back than current vehicles allow. Also, manufacturers should use obese crash-test dummies, in addition to the normal-weight ones, when testing cars for safety. What do you think about that?
