Food allergies can have various causes, ranging in severity from 'troubling' to 'very serious'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose food allergies, we could:
|Increased Intestinal Permeability||4%||Ruled out|
|Vitamin Pantothenic Acid Need||2%||Ruled out|
Do you have any reactions or allergies to specific foods which improve if you avoid those foods?
Possible responses:→ No / don't know
→ Mild reaction to one or two foods
→ Mild reaction to several foods / severe to 1 or 2
→ Severe reaction to several foods
Allergies are the body's response to increased histamine levels. Histamine helps control the flow of water in the body and histamine levels will rise in an attempt to manage dehydration, leading in some cases to increased allergic reactions and allergy-like symptoms.
