Anaphylaxis
The extreme allergic reaction known as anaphylaxis can threaten a person’s life. It can happen in seconds or minutes after an allergen has been exposed, prompting the immune system to unleash a torrent of chemicals that can induce shock. When a person is in a condition of shock, the blood pressure drops abruptly, and the airways constrict, making it impossible for them to breathe.
Histamine attaches to receptors in the body during an allergic reaction, resulting in several physiological changes. When there is excessive histamine in the system, several responses can occur, some of which can become highly dangerous or even fatal. However, histamine intolerance is related to allergic reactions because it can occur even without an allergen. This is because histamine intolerance is caused by a lack of the enzyme that breaks down histamine. Histamine intolerance can cause a potentially lethal condition known as anaphylaxis. This condition is considered among the more severe forms. The inability to breathe can result from swollen airways, and a sudden drop in blood pressure might deprive essential organs of blood supply.
