Asthma is usually diagnosed in childhood. The risk factors for asthma include: a personal or family history of asthma or atopy; triggers (see Pathophysiology above); premature birth or low birth weight; viral respiratory infection in early childhood; maternal smoking; being male, for asthma in prepubertal children; and being female, for persi ...

An acute exacerbation of asthma is referred to colloquially as an asthma attack. The clinical hallmarks of an attack are shortness of breath (dyspnea) and wheezing, the latter “often being regarded as the sine qua non.”[4] A cough—sometimes producing clear sputum—may also be present. The onset is often sudden; there is a “sense of constriction” in the chest, breathing becomes difficult, and wheezing o ...

Asthma is a disease of the human respiratory system in which the airways narrow, often in response to a “trigger” such as exposure to an allergen, cold air, exercise, or emotional stress. This narrowing causes symptoms such as wheezing, shortness of breath, chest tightness, and coughing, which are the hallmarks of asthma. Between episodes, most patients feel fine. The disorder is a chronic inflammatory condition in which the airways develop increased responsiveness to various stimuli, characterized by bronchial hyper-respon ...

Bronchoconstriction is the constriction of the airways in the lungs due to the tighting of surrounding smooth muscle, with consequent coughing, wheezing, and shortness of breath. Bronchoconstriction - Causes. The condition has a number of causes, the most common being asthma and exercise, and allergies. Bronchoconstriction - Exercise-induced bronchoconstriction. More generally termed exercise-induced asthma, the preferred and more accurate term exercise-induced ...

Asthma is a chronic inflammatory disease causing airflow obstruction. Leukotrienes assist in the pathophysiology of asthma causing: increased secretion of mucus mucosal accumulation bronchoconstriction infiltration of inflammatory cells in the airway wall Leukotriene - Cysteinyl leukotrienes. LTC4, LTD4 and LTE4 are often called cysteinyl leukotrienes due to the presence of the amino acid in their structure. Cysteinyl leukotriene receptors CysLT1 ...

Common causes of wheezing are: Asthma Chronic obstructive pulmonary disease Medication-induced bronchoconstriction Pulmonary edema Tracheobronchitis, and Vocal cord dysfunction Less common causes of wheezing include: Amyloid deposition Carcinoid syndrome Chondromalacia Descending aortic aneurysms Postlobectomy bronchial torsion Postradiation stenosis Tracheo-broncheal tumors

Allergy is characterised by a local or systemic inflammatory response to allergens. Local symptoms are: Nose: swelling of the nasal mucosa (allergic rhinitis) The distinctive behavior known as nasal salute, also known as allergy salute, is the habit of wiping of the nose in an upward direction due to itching. Eyes: redness and itching of the conjunctiva (allergic conjunctivitis) Airways: bronchoconstriction, wheezing and dyspnoea, sometimes outright attacks of asthma Skin: various rashes, such as eczema, hi ...

The most effective treatment for asthma is identifying triggers, such as pets or aspirin, and limiting or eliminating exposure to them. Desensitization is commonly attempted, but has not been shown to be effective. As is common with respiratory disease, smoking adversely affects asthmatics in several ways, including an increased severity of symptoms, a more rapid decline of lung function, and decreased response to preventive medications.[9] Asthmatics wh ...

Asthma - Bronchoconstriction. In essence, asthma is the result of an abnormal immune response in the bronchial airways.[5] The airways of asthmatics are “hypersensitive” to certain triggers, also known as stimuli (see below). In response to exposure to these triggers, the bronchi (large airways) contract into spasm (an “asthma attack”). Inflammation soon follows, leading to a further narrowing of the airways and excessive mucus production, which leads to ...

In most cases, a physician can diagnose asthma on the basis of typical findings in a patient's clinical history and examination. Asthma is strongly suspected if a patient suffers from eczema or other allergic conditions—suggesting a general atopic constitution—or has a family history of asthma. While measurement of airway function is possible for adults, most new cases are diagnosed in children who are unable to perform such tests. Diagnosis in children is based on a careful compilation and analysis of the patient's medical history and s ...
