(BHR) refers to the increased sensitivity of the airways to various stimuli, leading to narrowing of the airways, which can cause symptoms such as wheezing, coughing, chest tightness, and shortness of breath. This condition is closely associated with [[Asthma]], but it can also be seen in other respiratory diseases and in individuals without any diagnosed respiratory disorder.<br /> <br /> ==Causes and Mechanisms==<br /> The exact mechanisms underlying BHR are complex and involve a variety of cellular and molecular processes. Inflammatory cells such as eosinophils and mast cells play a significant role, releasing mediators that cause airway smooth muscle contraction, edema, and mucus production. [[Airway inflammation]] is a key factor, with various triggers including allergens, respiratory infections, exercise, cold air, and environmental pollutants contributing to the development and exacerbation of BHR.<br /> <br /> ==Diagnosis==<br /> Diagnosis of BHR often involves a detailed medical history and physical examination, focusing on respiratory symptoms and triggers. Pulmonary function tests, particularly spirometry, can assess the degree of airway obstruction. Bronchial challenge tests, using methacholine or histamine, are specific tests for BHR, measuring the airway&#039;s responsiveness to these agents.<br /> <br /> ==Treatment==<br /> Management of BHR aims to control symptoms and reduce exposure to known triggers. Pharmacological treatments include inhaled corticosteroids to reduce inflammation, bronchodilators to relieve airway constriction, and leukotriene modifiers. Non-pharmacological strategies involve avoiding allergens, smoking cessation, and possibly the use of air filters to reduce exposure to airborne irritants.<br /> <br /> ==Prevention==<br /> Preventive measures for BHR focus on controlling environmental factors and managing underlying conditions such as asthma. Regular follow-up with healthcare providers is essential to monitor symptoms and adjust treatment as necessary.<br /> <br /> ==Epidemiology==<br /> BHR is most commonly associated with asthma, affecting a significant proportion of asthmatic patients. However, it can also occur in individuals with other respiratory conditions and in the general population, with prevalence rates varying widely depending on the population studied and the diagnostic criteria used.<br /> <br /> ==See Also==<br /> * [[Asthma]]<br /> * [[Chronic Obstructive Pulmonary Disease (COPD)]]<br /> * [[Pulmonary Function Tests]]<br /> * [[Airway Inflammation]]<br /> <br /> [[Category:Respiratory diseases]]<br /> [[Category:Asthma]]<br /> [[Category:Pulmonary]]<br /> <br /> {{Medicine-stub}}</div> Prab
