Aside from autoimmunity, other causes of low thyroid function can be HPA axis dysregulation and chronic stress, a very low calorie or very low carbohydrate diet, sudden weight loss, a deficiency in nutrients needed for thyroid function such as iron, zinc, iodine and selenium, and a body burden of environmental toxins such as heavy metals.
