Asthma

Asthma is a respiratory disease that causes periodic narrowing of the passage of air entering and exiting the lungs, causing coughing, wheezing, and shortness of breath. This reduction is usually temporary and reversible, but in severe episodes asthma can lead to death. The most common form of asthma is bronchial asthma which is airway inflammation, but this term is also used to refer to cardiac asthma occurring when pulmonary exudate is a complication of heart failure.

One of the first health problems that asthma may cause an increase in contamination level. While the incidence of asthma in Utah is indeed better than the national average, most medical professionals believe that asthma is more common in the United States over the past few decades. One-tenth of Utah has asthma, which is about 9% of the population. Ozone exposure one week prior to childbirth is associated with a 13-22% increase in the risk of stillborn but the risk of long-term exposure during pregnancy has increased by nearly 40%. Exposure to PM 2.5 at the day before birth also appeared to increase the risk of stillbirth in a pollution model. Although the number of cases is small, maternal asthma alters the risk of stillbirth associated with chronic PM 2.5 and CO exposure. If our findings are confirmed, they think that about 8,000 stillbirths a year in the United States may result from O 3 exposure during pregnancy.

Many of the potential causes of asthma mainly explain the various ways that asthma may exist. In most cases, the disease begins in infancy between 2 and 6 years old. In this age group, the cause of asthma is often related to exposure to allergens such as mites, tobacco smoke, and viral respiratory infections. It is difficult to identify asthma in young children under 2 years of age. Wheezing in this age group is usually associated with viral infection and may disappear later without causing asthma. However, asthma may develop again in adulthood. Most adults with asthma develop females, most of them are middle-aged and respiratory infections often occur. The inducing factors of this group are usually nonallergic.

Asthma Since the mid-1980s, the incidence of asthma in the United States has soared to an epidemic level, particularly among young children. Approximately 16 million people suffer from asthma in the United States alone. Asthma is a serious chronic disease and can threaten life, but the lung is characterized by a recurrence of bronchoconstriction and causes dyspnea, wheezing, coughing. Researchers have discovered that exposure to pesticides can cause asthma-related poisoning. Low-income people, color people, and children living in the city center have much higher morbidity and mortality due to asthma. According to the National Institute of Allergy and Infectious Diseases Research Institute of National Institutes of Health, African Americans may die from asthma 4-6 times more than Caucasians.
