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:
|Vitamin Pantothenic Acid Need||2%||Ruled out|
|Increased Intestinal Permeability||1%||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
