Ig E Food Allergy

Ig E Food Allergy is an Immediate Food Reaction that most people are familiar with. As the name implies, this food reaction can occur within minutes or up to 3 hours after ingestion. Peanuts that cause anaphylaxis in a child is an Ig E food allergy. The reaction is caused by the presence of a high Ig E antibody levels in the blood, which sets off an immediate allergic response. Ig E antibodies make up only a small percentage of our immune system (about 5-10% of our white blood cells), but exert the most severe and life threatening reactions. Symptoms can include rashes or full body hives after eating an apple, immediate vomiting or diarrhea from milk, or an intense headache after drinking wine. These reactions can be tested for by either an allergist or a naturopathic doctor.

What Causes Hypothyroidism?

Chronic Stress & Adrenal Fatigue

The adrenal glands take the leading role when it comes to managing stress through the production of cortisol. Research shows that adrenal fatigue has an impact on thyroid function. Even at mild a degree of deficiency, adrenal fatigue can negatively affect thyroid hormone conversion, utilization, and production. For example, high stress can cause too much cortisol in the circulation which promotes inflammation around the thyroid, and this reduces thyroid receptor responsivity. Therefore, when treating thyroid issues it’s important to address the adrenals, this connection and to care for them both effectively.

Hashimoto’s Hypothyroid

90% of cases of hypothyroidism are due to an autoimmune attack on the thyroid gland by either thyroperoxidase antibodies (TPOAb) or by thyroglobulin antibodies (TgAb), a condition called Hashimoto’s thyroiditis. What this means is that the body creates immune cells that attack the gland so that function declines over time. This condition can be triggered by gluten in gluten-sensitive individuals. Similarly, in these people, gluten avoidance for at least 3 months may help lower antibody levels to a normal range.

Thyroid Conversion Disorder

In some cases, the conversion of T4 into T3 doesn’t function properly due an enzyme issue or otherwise. Test results will show normal levels of TSH and T4 but severely low levels of T3. Commonly, in these cases, people are often told by their doctors that their thyroid function is “normal” even though they do not feel normal! This is also why some people who are medicated with Levothyroxine or Synthroid (T4) may feel like their medication is ineffective.

Thyroid Hormone Resistance

Thyroid hormone resistance can be thought of in the same way as insulin resistance is in diabetics. In this condition, the body’s cells are unresponsive to thyroid hormones. In these individuals, T3 and T4 levels can be normal but TSH levels are elevated.

Nutritional Deficiencies

For proper function and the creation of thyroid hormones, the thyroid gland requires the trace minerals iodine, selenium and zinc as well as an amino acid, thyroxine. Deficiency in any of these nutrients, can create symptoms of hypothyroidism. Iodine is found in iodized salt and sea vegetables (such as nori and dulse flakes). I have come to find that iodine deficiency is more prevalent than previous given credit for (a 24 Hour Urine Iodine Challenge Test can determine this). The trace mineral Selenium is abundantly found in Oysters and Brazil nuts, and Zinc is rich in pumpkin seeds and beef. Thyroxine, is the amino acid building block of thyroid hormones and can be found in most sources of protein.

Heavy Metal Toxicity and Mercury

The thyroid hormone and the heavy metal mercury have strikingly similar biochemistry. If an individual has ever had mercury amalgams in their mouth (even if they have now been long removed), both the fact of having had them and likely having had them removed without the proper biological dentistry, the long term exposure of this metal wreaks havoc on the thyroid gland. Sometimes it is prudent to screen for heavy metal toxicity and high levels of mercury that may be causing thyroid suppression. Chelation Therapy for removal of mercury from deep tissue store is one way to treat the underlying hypothyroid condition.

Central Hypothyroidism

In rare cases, disorders of the pituitary gland or hypothalamus in the brain may be an underlying cause for central Hypothyroidism (AKA secondary or tertiary hypothyroidism). There are usually other concerning symptoms (beyond the list seen on this page) that would warrant imaging and more advanced hospital testing.

What causes insulin resistance or metabolic syndrome?

Factors that have been shown to cause or contribute to metabolic syndrome or insulin resistance include:

Poor diet
Being overweight
Lack of exercise/physical activity
Sleep apnea
Hormonal changes such as pregnancy, peri-menopause, menopause and andropause (male menopause)
Some medications including steroids and antidepressants
Some medical conditions such as Cushing’s and Polycystic Ovarian Syndrome (PCOS)
Vitamin and mineral deficiencies

What are the signs and symptoms of prediabetes?

You may be unaware that you have insulin resistance issues. Some of the signs and symptoms are similar to those of diabetes. Others are evidence of higher than normal amounts of insulin. Symptoms of insulin resistance may include:

Excess thirst
Frequent urination
Weight gain
Hormone imbalances (excess estrogen or testosterone)
PCOS (Polycystic Ovarian Syndrome)
Elevated cholesterol
High triglycerides
Elevated HbA1c or glycated hemoglobin
High blood pressure
Metabolic Syndrome
Fatigue or muscle weakness
Gestational diabetes
Acanthosis nigricans (darkened patches of skin on the neck, underarms, elbows, knees, knuckles)
