The rapid increase in obesity across the country has resulted in a number of serious health problems. Many of these health problems can deteriorate a person\’s quality of life and even shorten a person\’s life. One such health condition that is made worse when obese is asthma. Studies are now showing that there is a link between asthma and morbid obesity. For people who are suffering from severe obesity, lap band surgery has been shown to be an effective method of weight loss that reduces instances of severe asthma attacks.
Obesity has been proven to be a risk factor for such diseases as heart disease, some types of cancer, and diabetes. Now, research studies are revealing that obesity is a risk factor for asthma. For instance, studies now show the risk for developing asthma increases when there is a large increase in weight. When a person is seriously overweight, their breathing becomes shallow because their lungs do not expand as much as it would if one were a normal healthy weight. As well, in obese individuals, there is a chronic inflammation of the lungs which reduces the airway passage. The inflammation takes place in the fatty tissue. A narrower airway passage also means the airways will remain blocked when breathing normally which reduces oxygen exchange. The airways will contract more causing more asthma symptoms. Narrow airways in obese asthmatics are more likely to stay closed during normal breathing which results in reduced oxygen exchange which puts one in a higher risk category for pulmonary hypertension. As well, obese people are more prone to sleep apnea and gastroesophageal reflux disease which can make asthma worse.
