The Acute symptomatic type 1 is a type of allergy which could be attributed to the immunoglobulin E (IgE) antibodies. In these kind of cases, the symptoms of the allergy will occur fast after the food has been ingested. IgE reactions usually are immediate which is why they cause the most obvious allergic reactions. The IgE antibodies mostly attach themselves to the various cells or mastocytes and likewise to basophils in tissues towards some areas of the body like the skin, gastrointestinal tract, nose, throat and the lungs. Another thing is that it results on the release of large amounts of histamine and will likewise lead to some allergic reactions such as itching, inflammation, stomach cramps, sneezing and a whole lot more. For the cases that are extreme, there are the sudden fall of blood pressure.

The symptoms will then appear in almost three days after you have consumed a particular food with the antigens and if they are not diagnosed early, the ailment can be chronic instead of acute. The symptoms likewise are different from the food allergy type 1.
