The Buteyko method emphasizes the role of carbon dioxide and hyperventilation in respiratory diseases as well as overall health. It is known that hyperventilation can lead to low carbon dioxide levels in the blood (or hypocapnea), which can subsequently lead to disturbances of the acid-base balance in the blood and lower tissue oxygen levels.
The mechanisms behind allergic asthma—i.e., asthma resulting from an immune response to inhaled allergens—are the best understood of the causal factors. In both people with asthma and people who are free of the disease, inhaled allergens that find their way to the inner airways are ingested by a type of cell known as antigen-presenting ...
They are elongated microscopic mucous casts from small bronchi and are often found in sputum samples from patients with bronchial asthma. They can be stretched out to a length of around 2 cm and can sometimes be longer. They have a central core that may be ensheathed in cell debris and mucus. [3]
The effects of bronchial thermoplasty on smooth muscle mass are seen up to at least 12 months post-treatment; however, the procedure does not seem to impact other features of airway remodelling. [4] Thus far, no pharmacological treatment modality for asthma has been developed nor shown to prevent or attenuate the progression of airway remodelling.
Asthma is a common condition and affects over 300 million people around the world. [3] Asthma causes recurring episodes of wheezing, breathlessness, chest tightness, and coughing, particularly at night or in the early morning. [4] Exercise-induced asthma is common in asthmatics, especially after participation in outdoor activities in cold weather.
Asthma, chronic bronchitis, bronchiectasis and chronic obstructive pulmonary disease (COPD) are all obstructive lung diseases characterised by airway obstruction.This limits the amount of air that is able to enter alveoli because of constriction of the bronchial tree, due to inflammation.
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
Asthma is a respiratory disease that can begin or worsen due to exposure at work and is characterized by episodic narrowing of respiratory airways. Occupational asthma has a variety of causes, including sensitization to a specific substance, causing an allergic response; or a reaction to an irritant that is inhaled in the workplace. Exposure to ...
