Researchers have studied this concept to determine if and why this link occurs. In truth, the link itself can be confusing. For example, one study of identical twins found that if one twin suffers from asthma, the other twin only has a one in three chance of developing asthma. 

That said, the reason for the genetic link between blood relatives and asthma is just that- simple genetics. However, this risk can be increased by being exposed to asthma triggers (like things individuals are allergic to or chemicals in the workplace).

Weight and asthma go hand in hand. In fact, a review published in the Journal of Asthma and Allergy reports that asthma statistics are highest in obese adults, with 12 percent of obese adults suffering from asthma. However, just over seven percent of normal weight individuals suffer from asthma.

Statistics on overweight children and asthma are equally alarming. Everyday Health reports that one study concluded that obese children and teens may be twice as likely to become asthmatic compared to children who are not obese.

In addition, research shows that overweight adults with asthma may be five times more likely to be hospitalized due to asthma compared to those who are not grossly overweight and suffering from asthma.

It appears that weight loss can alleviate symptoms of this condition. In fact, studies show that losing weight (for those who are obese) can be linked to a 48 percent to 100 percent alleviation of symptoms of asthma and the need for medication to treat the condition. In addition, lungs appear to function better once weight is lost.
