Causes
Anaphylaxis is an acute systemic reaction caused by the release of mediators from mast cells and basophils. These cells are part of the immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body. and respond to certain allergens by releasing histamine and other chemical substances. These substances cause dilationDilation refers to the widening or expansion of a hollow organ or vessel. It can be physiological (normal) or pathological (due to disease). of blood vessels, increased vascular permeabilityVascular permeability refers to the permeability of blood vessel walls, which allows the exchange of fluids, nutrients, and other substances between the bloodstream and surrounding tissue. Increased permeability can occur in inflammatory conditions or injuries., and contraction of smooth muscle, leading to the typical symptoms of allergic shock.
The causes of anaphylaxisAnaphylaxis is a rapid, severe allergic reaction that is potentially life-threatening. It can be triggered by various factors, including food, medications, and insect stings, and requires immediate medical attention. in dogs can be varied. Common triggers include insect bites, especially from bees and wasps, certain foods, medications such as antibiotics or vaccines, and in some cases, environmental allergens.
