Is inflammation of the mucous membranes lining the nasal cavities due to allergic processes. As a consequence of the inflammation, the cells start producing excess mucus, which runs down the nostrils.
Repeated outbreaks of allergic rhinitis in children may cause definitive nasal obstruction, which leads to bone changes at the base of the skull. Because rhinitis has a strong emotional component, affection and good psychological conditions are part of treating the disease.
It is a respiratory disease in which spasm and constriction of the bronchi and inflammation of the mucosa limit the air passage, causing difficulty breathing. It is often due to an allergy, in particular to animal dust, hair or feathers, mold and pollen. Many allergic asthma patients, called atopic or extrinsic asthma, also suffer from hay fever, which is a form of seasonal rhinitis caused by pollen allergy. Its symptoms are intense sneezing attacks, inflammation of the nasal mucosa and eyes, and difficult breathing.
It is a lung disease characterized by a decrease in caliber (constriction) of the bronchioles. Asthma can have many causes, the most common being allergic. Also having strong triggering of asthma attack.
Asthmatic crisis occurs when the smooth muscles of the bronchioles contract spasmodically. The mucosa lining the bronchioles internally swells and produces more secretion, which contributes to reducing the size of the respiratory conduits. Breathing difficulty impairs blood oxygenation and, in very severe cases, cyanosis (bluish discoloration of the skin and mucous membranes) may occur, caused by the accumulation of carbon dioxide in the blood.
