Causes and Symptoms


Dr. David Brownstein has discovered Thyroid Causes, through his research and clinical experience with over 6,000 patients, that approximately 96% of people are deficient in iodine in the United States alone. Iodine concentrates in the glandular tissue and its job is to maintain the proper structure of that tissue. When we are iodine-deficient  for long periods of time we begin attracting problems like cysts, nodules and eventually cancer in the thyroid and other glands. For this the easy solution is to use comfortable amounts of iodine, iodised salt and eating more seafood (smaller fish and shellfish). Also to reduce your exposure to the chemicals, fluoride and bromine.

As the classic environmental disease, Thyroid condition has a collection of causes and never just one.  there are certain chemicals which can clog up hormone receptors on the cells in your thyroid. One of the most common chemicals is chlorine, and we breathe in a lot of chlorine in our nice warm shower every day. Not everyone has this type of sensitivity, but it’s way more common than people realise. One way to tell if this is affecting you is to see if you seem to be able to smell chlorine more acutely that other people. In other words, do you notice a chlorine smell in your water. If so, it might be time for a filter on your shower. Other chemicals that could affect the thyroid in sensitive people although to a lesser extent than chlorine are fluoride and bromine.
The majority of thyroid issues manifest in women, and among the dozens of symptoms that those issues can cause is the inability to lose weight. One of the most popular current trends for weight loss happens to be a low-carb diet or even a low-carb Paleo diet. Unfortunately, this is one of the worst diets you can subscribe to, particularly for women with thyroid issues.
As Dr. Sara Gottfried, author of The Hormone Cure, points out, women have a much more complex system then men. So, what works for guys won’t necessarily work for women, and that’s even truer for women with thyroid issues. Think of carbohydrates as thyroid food. Studies have shown that fasting or significant caloric restriction can reduce T3 production dramatically. The same has been shown for carbohydrate restriction.
This is why it’s fairly common for people – particularly women – to experience hypothyroid symptoms when following a low-carb diet. But there is more on that. It seems that the experiential finding is that once the thyroid is lifted in function up over 75% then we can get back into the low carb paleo and ketogenic diets with no worries beyond using ongoing methods to keep the thyroid high profile!

Gluten sensitivity is a big problem to people with coeliac disease, depending on the parameters of assessment this now affects from one to twenty percent of americans. Gluten is also a problem without any connection to coeliac. Gluten sensitivity is common to about 35%. Connection to the thyroid problems has been established by all the real specialists in thyroid, all recommending total abstinence from any form of gluten.  The body creates antibodies or chemical bullets which can actually damage thyroid tissue because of similarities in amino acid composition to gluten. So get rid of irritating foods first. Any wheat, rye or barley as products or thickeners. Even shampoos have wheat thickeners. If you have the symptoms of hypothyroid fact is you probably have it even if the tests turn up negative because there are multiple causes and not all are covered by tests anyway.


Thyroid is the thermostat amongst other things. Every cell in the body has thyroid receptor sites and vitamin D receptor sites indicating their importance in the body. So common symptoms will include the following

You will be cold or at least feel the cold more than others.

Thyroid disfunction symptoms include cold feet especially.


Brain functions can be slow, 

It is always hard to lose weight especially that last bit around the tummy. 

Distal third of the eyebrow can be very sparse or non existent. 

Dry or easily affected skin is common.
