Other things can irritate the already-sensitive air passages of asthma or allergy sufferers. Rather, a protein found in the pet's saliva, dander (skin) and urine can cause allergies in some individuals.
Contrary to popular belief, dog and cat fur don't cause allergies. An estimated 60 percent of people with asthma have airborne allergies.Ĭommon allergens include: dust mites, mold, pollen, cockroaches, animal dander and certain foods. But not all asthma sufferers have defined allergies. Asthma sufferers may have allergies to certain proteins, known as allergens, which are usually airborne and can trigger an attack. Researchers aren't sure why some people's airways are more sensitive to things in the environment. Women are also more likely than men to die from asthma. There is some evidence that asthma may be affected by hormonal changes during a woman's cycle and can be triggered prior to or during the menstrual period. Women may first develop asthma during or after pregnancy, though the condition may also improve during pregnancy. People who have allergies are at an increased risk of developing asthma, and those raised in environments where they were exposed to cigarette smoke also have a much higher incidence of the condition.
Pollution, poor air quality in urban environments, poverty and lack of patient education are also factors contributing to rising asthma and asthma-related complication rates. Children of parents with asthma are at greater risk for developing the condition. Obesity significantly increases a person's risk of developing the condition. Some individuals have their first asthma attack after age 50. But many people develop the condition in adulthood, after age 20-known as adult onset asthma. The condition is becoming more common and more severe across all age, sex and racial groups.Īsthma typically develops during childhood. Centers for Disease Control and Prevention, or CDC) reported that 18.45 million American adults and 6.2 million children suffered from asthma in 2015. The National Center for Health Statistics (a division of the U.S. It is very important to rule out cardiac arrest or other heart-related disease when these symptoms occur, because the symptoms can be similar. Asthma can be controlled with the proper diagnosis and treatment. Wheezing, coughing and/or tightness in the chest and shortness of breath are all hallmark symptoms of a classic asthma attack. When the lungs react severely to a trigger, what's known as an "asthma attack" may occur. The airways can swell as a result of inflammation made worse by an elevated number of a type of white blood cells known as eosinophils, which are markers for severe asthma. The mucus can clog the bronchial tubes, which contributes to breathing problems. In addition, cells in the lungs can produce mucus in response to triggers. These triggers can cause airway obstruction or blockage where the lungs tighten, constricting the air passages and making breathing difficult. People with asthma can be more sensitive than other people to triggers, such as substances inhaled from the environment, odors, temperature changes and physical activity. What Is It? Asthma is a lung condition that makes the primary airways-known as the bronchi-in the lungs swollen and inflamed all of the time.Īsthma is a lung condition that results in the large and small airways-known as the bronchi and bronchiole-in the lungs becoming swollen and inflamed.
