Food Allergies and Intolerances
Dr. Weyrich's Naturopathic Functional Medicine Notebook
Overview
Food allergies may be either immediate reaction (IgE) or delayed reaction (IgG).
Food intolerances are distinguished from true allergies, and may be due to
inability to digest or absorb certain foods, such as lactose.
Etiology
Dysbiosis leading to
leaky gut syndrome is commonly associated with food allergies.
Some authors have noted that allergies are more common in
hypothyroid conditions, and respond well to treatment
of the underlying hypothyroid condition [Starr2005, pg 108].
Differential Diagnosis
Basal body temperature below 97.8 degrees F, elevated TSH, or depressed T3
(suggests hypothyroidism).
Adrenal insufficiency.
Treatment
- IgG blood food allergy testing followed by avoidance of problematic foods.
- Elimination diets are a low-cost alternative to IgG blood testing, but take longer and
are a hassle for the patient to implement.
- Treat underlying leaky-gut syndrome.
