Vaikeimmissa tapauksissa ongelma yritetään ratkaista toiminta- ja työkykyä ylläpitävällä terapialla. Genes seem to play a role in making some people more susceptible to asthma. For example, some genes are involved in how your immune system responds to allergens. These genes can cause a stronger reaction in your airways when certain substances in the air end up there. The genes involved may be different in different people.In support of our mission, we are committed to advancing asthma research in part through the following ways.Shlomi D, Katz I, Segel MJ, Oberman B, Peled N.

Altisteen välttäminen yleensä estää oireilun. On kuitenkin muistettava, että pyrkimys täyteen välttämiseen voi vahvistaa altisteen vaaramerkitystä ja siten voimistaa reaktioita. Omaan käyttäytymiseen ja sietokykyyn kannattaa pyrkiä vaikuttamaan siten, ettei oire ala liikaa rajoittaa elämää.

Asthma affects people of all ages, but it often starts during childhood. Sometimes asthma develops in adults, particularly women. This type of asthma is called adult-onset or late-onset asthma.Asthma attacks are episodes that occur when symptoms get much worse. Asthma attacks can happen suddenly and may be life-threatening. People who have severe asthma experience asthma attacks more often.Asthma symptoms occur when the airways of the lungs narrow, which makes it more difficult to breathe. This narrowing is usually caused by inflammation, which makes the airways swell and may cause the cells of the airway to make excess mucus. Bronchospasm, or tightening of the muscles around the airways, also makes the airways narrow and results in trouble breathing.Mccracken JL, Veeranki SP, Ameredes BT, Calhoun WJ. Diagnosis and Management of Asthma in Adults: A Review.

Asthma is a chronic inflammatory disease of the respiratory system characterized by bronchial hyperresponsiveness, episodic exacerbations (asthma attacks), and reversible airflow obstruction. Allergic (extrinsic) asthma usually develops in childhood and is triggered by allergens such as pollen, dust mites, and certain foods. Nonallergic (environmental or intrinsic) asthma usually develops in patients over the age of forty and can have various triggers, such as cold air, medication (e.g., aspirin), exercise, and viral infection. The cardinal symptoms of asthma are intermittent dyspnea, coughing, and high-pitched expiratory wheezing. Symptoms remit in response to antiasthmatic medication or resolve spontaneously upon removal of the trigger. Confirmation of the diagnosis involves pulmonary function tests, allergy tests, and chest x-ray. First-line treatment consists of inhaled bronchodilators (e.g., short-acting beta-2 agonists) for acute exacerbations and inhaled corticosteroids (e.g., budesonide) for long-term asthma control. Patients should be taught the correct usage of inhalers for self-medication and measurement of peak expiratory flow (PEF) to self-monitor disease progression and severity. Severe asthma exacerbation can be life-threatening and may require emergency treatment and/or hospitalization. Asthma is the most common inflammatory condition of the lung.

Tuoksuyliherkkyyttä ei voi todeta objektiivisilla mittauksilla. Tarvittaessa diagnoosin asettaminen perustuu oirekyselyyn. Voimakkaampia oireita voi olla hankala erottaa esimerkiksi paniikkihäiriöstä. Tuoksuyliherkät eivät koetilanteissa erota eri tuoksuja kontrollihenkilöitä paremmin, mutta siinä missä tuoksuille reagoimattoman henkilön aistit tottuvat nopeasti voimakkaaseenkin tuoksuun, tuoksuyliherkän elimistössä ei tottumista tapahdu.

Different types of microbes live throughout the environment and within each person’s body. The microbes may differ depending on the environment, such as where you live. Researchers found that being exposed to certain types of microbes or higher amounts of certain microbes during childhood can affect how your immune system develops. This in turn can determine whether you have allergic reactions later in life. For example, people who lived on farms as children were exposed to more types of microbes, and research suggests that this may have helped prevent asthma later in life. Learn more about our research that explores whether microbes might be involved in asthma related to dust-mite allergies.
