Food Allergies and Hypothyroidism

Posted on by IBSTC

Hypothyroidism is a serious condition found in people with and without food allergies.

However, people with food allergies, particularly those with celiac disease (a gluten allergy), frequently suffer from hypothyroidism. It’s known to cause fatigue and weight gain as well as other problems, and is often overlooked and misdiagnosed due to complexities in thyroid testing and symptoms which may overlap or contradict the symptoms of food allergies.

What Are the Symptoms of Hypothyroidism?

Lack of adequate thyroid hormone production may result in one or more of the following symptoms: fatigue, weight gain, constipation, cold extremities, inability to focus, forgetfulness, dry skin and depression.

How Is Hypothyroidism Typically Diagnosed?

Most physicians measure thyroid function not by testing thyroid hormones, but by testing levels of TSH. TSH stands for Thyroid Stimulating Hormone. TSH is produced by the pituitary gland and stimulates the thyroid gland to produce thyroid hormones.

As thyroid hormone production drops, TSH levels are supposed to automatically increase to compensate for low thyroid hormone levels. Therefore a higher than normal TSH level indicates a hypothyroid condition.

Why Does Hypothyroidism Frequently Go Undiagnosed?

Unfortunately, TSH doesn’t always respond correctly to low thyroid hormone levels. If the actual thyroid hormones themselves (called T4 and T3) are not checked, hypothyroidism can be missed. I’ve seen several cases of hypothyroidism with low thyroid hormone production and a normal TSH level.

Also, most physicians are using old data and a normal reference range that is too large when determining whether or not the TSH level is normal. This means that many people are being told that they have a normal thyroid when, according to the latest scientific standards, they are actually hypothyroid.

What Is the Current Standard for Determining Hypothyroidism?

The American Association of Clinical Endocrinologists recommends that the normal reference range for TSH be reduced by nearly half, down to 0.50-2.50. The old range is 0.50-5.00. (The higher the number, the more hypothyroid you are.) This means that thousands of people are being misdiagnosed and are actually hypothyroid. Unfortunately, most physicians have been slow in adopting these new standards and many people continue to be misdiagnosed.

I have battled fatigue, sadness, stomach issue diagnosed as IBS, and hellish allergies since I apwas in my 20’s. Just recently, I treated myself to a 51+ full medical exam. I’ve have zero thyroid production and a super high TSH level, along with a high blood sugar level. I’m a fitness trianer, college prof, and endurance athlete.
I have to hope the start of thyroid hormone replacement helps, because I can’t go on living like this.

There may be more going on. If the thyroid therapy doesn’t get you all the way there, please contact us. There may be more testing that can help.

I have bit myself on a 1200-1500 calorie diet I zumba 5 days a week & so pilates anywhere from 3-5 days a week to help reduce stress. My TSH was tested in March @an urgent care because I was having R side pain. It was 2.65 @that time. I was told it was my endometriosis go see your ob-gyn doc. My TSH was just test again on 5/12 it is now 3.35 & my Gen practice doctor told me it was in normal range almost a point increase is not normal. I am waiting for a referral to an endocrinologist. I started over 30 days ago taking an Iodine supplement to try to help as a NP friend said i might need some Iodine as I dont eat a lot of foof qith iodine. Could my TSH of been higher than 3.35 since I have been taking the Iodine for over 30 days???
