How Asthma Affects Lung by vikyembassy2000(f): 9:37pm On Jun 16, 2016 |
WHAT IS ASTHMA Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways. Figure A shows the location of the lungs and airways in the body. Figure B shows a cross-section of a normal airway. Figure C shows a cross-section of an airway during asthma symptoms. TYPES OF ASTHMA ALLERGIES and ASTHMA : Allergies and asthma often go hand-in-hand. Allergic rhinitis (also called hay fever) is inflammation of the inside lining of the nose and is the single most common chronic allergic disease. In those with allergic rhinitis , increased sensitivity ( allergy ) to a substance causes your body’s immune cells to release histamines in to contact with the allergens. Histamines, along with other chemicals, lead to allergy symptoms. The most common allergens enter the body through the airway. With allergic rhinitis , you may feel a constant runny nose, ongoing sneezing , swollen nasal passages, excess mucus, weepy eyes, and a scratchy throat. A cough may result from the constant postnasal drip. Many times asthma symptoms are triggered by allergic rhinitis. Your doctor may prescribe medications to control the allergies and, in doing so, the cough and other asthma symptoms may subside. EXERCISE -INDUCED ASTHMA Exercise -induced asthma is a type of asthma triggered by exercise or physical exertion. Many people with asthma experience some degree of symptoms with exercise. However, there are many people without asthma, including Olympic athletes, who develop symptoms only during exercise. With exercise-induced asthma, airway narrowing peaks five to 20 minutes after exercise begins, making it difficult to catch your breath. You may have symptoms of an asthma attack with wheezing and coughing . Your doctor can tell you if you need use an asthma inhaler (bronchodilator ) before exercise to prevent these uncomfortable asthma symptoms. COUGH VARIANT ASTHMA In the type of asthma called cough-variant asthma, severe coughing is the predominant symptom. There can be other causes of cough such as postnasal drip, chronic rhinitis, sinusitis , or gastroesophageal reflux disease (GERD or heartburn). Coughing because of sinusitis with asthma is common. Cough-variant asthma is vastly underdiagnosed and undertreated. Asthma triggers for cough-variant asthma are usually respiratory infections and exercise. For any persistent cough, contact your doctor. Your doctor may order specific asthma tests, such as lung function tests , to show how well your lungs work. You might need to see a lung specialist for further tests before an asthma diagnosis is made. OCCUPATIONAL ASTHMA Occupational asthma is a type of asthma that results from workplace triggers. With this type of asthma, you might have difficulty breathing and asthma symptoms just on the days you're on the job. Many people with this type of asthma suffer with runny nose and congestion or eye irritation or have a cough instead of the typical asthma wheezing . Some common jobs that are associated with occupational asthma include animal breeders, farmers, hairdressers, nurses, painters, and woodworkers. NIGHTTIME (NOCTURNAL)ASTHMA Nighttime asthma, also called nocturnal asthma, is a common type of the disease. If you have asthma, the chances of having symptoms are much higher during sleep because asthma is powerfully influenced by the sleep - wake cycle (circadian rhythms). Your asthma symptoms of wheezing, cough, and trouble breathing are common and dangerous, particularly at nighttime. Studies show that the most deaths related to asthma occur at night. It’s thought that this may be because of increased exposure to allergens (asthma triggers ), cooling of the airways, reclining position, or even hormone secretions that follow a circadian pattern. Sometimes heartburn can cause asthma at night. HEALTH CONDITIONS THAT MAY MIMIC ASTHMA A variety of illnesses can cause some of the same symptoms as asthma. For example, cardiac asthma is a form of heart failure in which the symptoms mimic some of the symptoms of regular asthma. Vocal cord dysfunction is another asthma mimic. CAUSES OF ASTHMA It isn't clear why some people get asthma and others don't, but it's probably due to a combination of environmental and genetic (inherited) factors. Asthma triggers Exposure to various irritants and substances that trigger allergies (allergens) can trigger signs and symptoms of asthma. Asthma triggers are different from person to person and can include: Airborne allergens, such as pollen, animal dander, mold, cockroaches and dust mites Respiratory infections, such as the common cold Physical activity (exercise-induced asthma) Cold air Air pollutants and irritants, such as smoke Certain medications, including beta blockers, aspirin, ibuprofen (Advil, Motrin IB, others) and naproxen (Aleve) Strong emotions and stress Sulfites and preservatives added to some types of foods and beverages, including shrimp, dried fruit, processed potatoes, beer and wine Gastroesophageal reflux disease (GERD), a condition in which stomach acids back up into your throat. SIGNS AND SYMPTOMS OF ASTHMA Shortness of breath Chest tightness or pain Trouble sleeping caused by shortness of breath, coughing or wheezing A whistling or wheezing sound when exhaling (wheezing is a common sign of asthma in children) Coughing or wheezing attacks that are worsened by a respiratory virus, such as a cold or the flu. HOW ASTHMA AFFECTS LUNG People with asthma have airways that are very sensitive to one or more triggers. Exposure makes airways begin to spasm, becoming red, swollen and narrow. Mucous is produced and gathers in the airways. TREATMENT the use of, garlic,ginger,echinacea and licorice root,turmeric,honey and omega-3s. So I recommend.immune booster,omega plus,royal jelly,defender,buchu power For more info call or whasapp 08086969372.
