Asma sulfites

Asthma has been rising in the US. UU. Over the past 50 years and is now more common chronic disease in America, affecting 20 million of us.
Asthma occurs when triggered in the environment cause the airways or bronchi in the lungs to contract, causing breathing difficulty, as shown above, can be fatal. There are a variety of possibilities for the increase in asthma in recent decades. It could be because we have less exposure to infection than our ancestors did, which has made more sensitive immune system. We spend more time indoors in controlled environments, where they are exposed to dust and mold. The air we breathe, both inside and outside, is more polluted than the air most of our ancestors breathed. We are more sedentary and, in particular, as we have moved from a rural to urban lifestyle over the last century have lost the habit of daily exercise, mainly in the form of walking and working outdoors on a daily basis.

There is considerable evidence that lack of outdoor exercise contributes to asthma and exercise program helps asthmatics. Our sedentary lifestyle has also led to an increase in obesity, there is evidence of an association between obesity and asthma related to the fact that obese people have a smaller area for the lungs to expand, higher levels of hormone leptin (fat which is released and is also higher in asthmatics) and higher levels of inflammatory markers (which may contribute to airway reactivity). In fact, as many as 75 of emergency room admissions for asthma are obese people. Finally, there has been a significant change in our diet, including a massive increase in exposure to vitamins and minerals through fortified foods as well as a change of corn grain based nutrition. There is some evidence that dietary changes in our culture may have contributed to the increase in asthma.

Two types of asthma: allergic, also known as extrinsic asthma and non-allergic or intrinsic asthma. Allergic asthma, the most common form, affecting 20 million people in the USA. It is triggered by an allergic reaction to something that has inhaled allergens such as dust mites, pet dander, tree or plant pollen, mold, or air pollution. People with allergic asthma have high blood levels of something called immunoglobulin E (IgE). IgE surface session airway allergen binds and causes mast cells and basophils to release inflammatory factors that cause respiratory limit (IgE in the nose and the mouth causes way hay fever, skin and causes IgE eczema). Symptoms include coughing, wheezing, shortness of breath or rapid breathing and chest tightness. No allergic asthma is triggered by factors unrelated allergens.

No allergic asthma is triggered by other factors such as infections of the upper respiratory tract, anxiety, stress, exercise, cold or dry air, hyperventilation, smoke, viruses, exercise, drugs, beta blockers, ACE inhibitors, and sulfites are in red wine, and gastro-esophageal reflux disease. As allergic asthma, non-allergic asthma is characterized by airway obstruction and inflammation can also be treated with partially reversible and similar to those used for allergic asthma. Many of the symptoms of allergic asthma are lack of them suffering experienced by allergic asthma. While blood levels of IgE are normal in non-allergic asthma, a similar type of inflammatory response occurs in the airways, for reasons that are not fully understood.
