Hidden Cause #2 Why You Still Have Low Thyroid Symptoms

Today I’m going to reveal hidden cause number two, why you still have thyroid symptoms.

This series is designed to do is to help open your eyes so that you can understand why you still are suffering with symptoms like fatigue and hair loss, low libido, feeling cold….understand why you still have those symptoms even though you’re taking thyroid hormones…. or even though your thyroid numbers look normal.

And hidden cause number two why you’re still suffering is because of a neurotransmitter called Dopamine.

Now I’m going to keep this science really simple…..

Your pituitary, which is a very small gland in your brain, makes thyroid stimulating hormone – TSH.

I’m sure you probably heard of that because that’s probably the only thing your doctor is monitoring, right?

Monitoring TSH is the only thing the status quo medical model does when it comes to thyroid hormone problems.

Pretty much no matter what the doctor thinks your problem might be (and they really only think it’s about one of two things) you get prescribed thyroid hormones.

The doctor doesn’t actually manage your thyroid problem… the doctor manages your TSH.(!)

So, if your TSH gets too high, well they increase your medication.  If your TSH gets too low, they decrease your medication. (so easy I could teach a 5 year old to do it).

The doctor looks at your TSH levels as the Be-All End-All… that couldn’t be more wrong.

The  thing about thyroid hormone problems that confuses most doctors and endocrinologists is there are  about 24 different ways that your thyroid hormones can go wrong – 24.

And most of your doctors are only testing TSH and total T4 and that’s about it.  That’s going to detect only 1, maybe 2 of the 24 different patterns.

The one I’m revealing to you today is Dopamine.

Your hypothalamus in your brain tells the pituitary to make TSH.

The Dopamine problem and its connection with thyroid works like this...there has to be sufficient Dopamine in your hypothalamus to generate the signal to pituitary to make TSH.

If there’s not enough Dopamine activity in your brain, then your pituitary doesn’t know how to make TSH.

Now, The TSH number on your labs will be within the normal lab range, but outside what I call the functional range.

The functional range is different than the lab’s range, because the lab range is pretty much garbage as a reflection of optimal function. It’s so wide that only the very high and very low get flagged.

…So with this Dopamine problem your TSH looks normal but you have thyroid symptoms—cold, fatigued, depressed, can’t lose weight, hair loss.  You may even be taking thyroid hormones.

“How Do I Know if You Have the Dopamine Problem?”

The clue to the Dopamine problem is  that you have, along with the fatigue and libido problems and the depression and the constipation and the can’t lose weight—along with those thyroid symptoms you have Dopamine symptoms.

The classic symptoms of insufficient Dopamine are:

  • feelings of worthlessness
  • anger and aggression when under stress
  • feelings of hopelessness
  • difficulty paying attention
  • distracted from task
  • inability to finish tasks
  • self-destructive thoughts


  1. If you’re suffering with those Dopamine symptoms
  2. AND you’re suffering with those thyroid symptoms
  3. BUT your TSH looks normal
  4. AND you’re taking thyroid hormone…

Then there’s a really good chance that Dopamine is why you still have a thyroid problem.

This Dopamine problem can be helped with special diet modification, lifestyle changes and specific supplementation.

Blood sugar control is probably the biggest thing to look at because Dopamine synthesis is  linked with blood sugar fluctuations.

ALERT: I don’t want you to fall victim to  the idea that you can test central nervous system neurotransmitter levels with urine testing.  That’s not valid at all.

I use an extensive questionnaire that helps me pinpoint specifically if you do actually have those Dopamine problems.

If you do, then I have to start digging into WHY do you have those Dopamine problems–this takes some detective work.  That’s what a good doctor will do.

If you’re suffering with thyroid hormone symptoms AND those Dopamine symptoms, dopamin can be the reason why you are still suffering, even though your labs look normal.
