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.

This is in fact associated on the delayed food reactions and that the patient could hardly experience any of such symptoms which are common towards allergies. The capacity of IgG4 in releasing histamines is actually weak and there are no inflammatory reaction. Read more, click here: link to gluten-free pregnancy.

 

The delayed type III is where the predominant antibody is not IgG4, but this could either be IgG, IgG3 or the IgG1, which can trigger the allergic symptoms. 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.

 

The type III or delayed reaction in fact are estimated to affect for half of the population. In case that the body is not capable of tolerating with some foods, it actually produces an inflammatory response and the continued consumption on a particular food and the physical symptoms could appear after few days.
