Does A Slow Thyroid Make You Look Older?

Yes, in Dr. Martin's view. He says a thyroid that is not working properly shows up almost everywhere in the body, hair first, and he is blunt that thinning hair before 90 is not simply age.

Key takeaways

  • He uses the word sluggish rather than normal or abnormal, because the lab range is so wide.
  • He calls the thyroid your gas pedal, which is why it shows up everywhere.
  • It is very rare, he says, to see a thyroid not working without signs almost everywhere in the body.
  • Unless you are 90, he says your hair should not be thinning.
  • Hair, eyebrows, skin and nails are the outward signs he looked at first in women.

Does a slow thyroid make you look older?

In Dr. Martin's view, yes. Not because the thyroid is a beauty gland, but because of where it sits in the body.

Dr. Martin on how far it reaches:

It's very rare that you will see a thyroid that is not working properly, that doesn't have manifestations almost everywhere in your body.

Dr. Martin, The Doctor Is In, Episode 839

Almost everywhere includes the parts you can see in a mirror. That is the whole argument of this page, and it is why he told women to use their eyes on themselves before they went looking for a number.

Why he says sluggish, not abnormal

He picked his own word for this on purpose.

Dr. Martin on the term he used with patients:

I would use the term your thyroid is sluggish.

Dr. Martin, The Doctor Is In, Episode 839

His reason is the TSH range. He describes the normal band in a lab as running from here to eternity, which is his way of saying it is wide enough to swallow a lot of people who do not feel well. He says he was a big man on symptoms and would not rely on the blood work, because too many people sitting in front of him did not feel right and had been told their thyroid was normal.

Sluggish is the word for that gap. Not broken, not flagged, just not doing the job at the speed it should.

The thyroid as the gas pedal

Dr. Martin on the picture he uses:

Because your thyroid, folks, is your gas pedal in your car.

Dr. Martin, The Doctor Is In, Episode 839

You are in the car and you cannot press the pedal. You are running in neutral, not really advancing. He calls it your body's thermostat as well, which is why cold hands and cold feet turn up on the same list.

Follow the image and the appearance question answers itself. If the pedal is down, everything that needs energy to renew itself gets it. Hair, skin, nails, all of it is the body rebuilding constantly. Run in neutral and rebuilding is the first thing that slows.

Hair

Hair was where he started with women, and this is his most quoted line on it.

Dr. Martin on thinning hair:

Now listen, unless you're 90 years old, your hair shouldn't be thinning.

Dr. Martin, The Doctor Is In, Episode 839

That is a direct shot at the sentence most women get, which is that this is just part of life and part of menopause. He had endocrinologists come to see him who could not sort out their own hormones and had been told their blood work seemed normal.

If you're losing it, your thyroid's involved somehow.

Dr. Martin, The Doctor Is In, Episode 839

He is careful about the word somehow. It may not be the primary thing, he says, but it may be. Then the instruction he leaves you with:

And when your hair's not right, think thyroid.

Dr. Martin, The Doctor Is In, Episode 839

Skin, nails and the rest

Eyebrows are the next thing he tells women to look at, the outer third especially. Then the things that get filed under age without anyone checking: skin that has gone dry, nails that split or break, feeling cold when nobody else is, weight that went on without the food changing, sleep that is not restoring anything.

None of those proves a thyroid problem on its own. His argument is about what happens when you have four or five of them at once and each one gets explained away separately. Dry skin becomes moisturiser. Thinning hair becomes a different shampoo. The weight becomes willpower. Nobody puts the list back together.

That is what he means by observing. Line them all up first, then go and get the blood test, and take the list with you.

What sits underneath

He never stops at the thyroid, because he does not think the thyroid acts alone. Two things sit underneath it on this episode.

The first is hormones in general. For a woman he describes it as a balancing act, a tightrope walk, which is why the thyroid symptoms and the menopause symptoms get so tangled together.

The second is the liver. T4 has to be converted into T3 to do anything, and that conversion happens in the liver and, about 20 per cent of it, in the gut. So a liver full of fat gets in the way of a thyroid working properly. He puts it as emptying the parking lot of your liver so the thyroid can do its job. The fatty liver story is in it only takes a month of eating sugar to get fatty liver, and the thyroid one is in the thyroid never acts on its own.

On nutrition he is short about it. The thyroid loves iodine and it loves selenium, and steak is where he sends you for the selenium.

Common questions

Does hypothyroidism make you look older?

He says yes, because it is very rare to see a thyroid not working without signs showing up almost everywhere in the body, including the visible ones.

Can a thyroid problem cause hair loss?

He says if you are losing your hair, your thyroid is involved somehow. He allows that it may not be the primary cause, but he would not leave it out.

Is thinning hair just part of aging?

He says unless you are 90 years old your hair should not be thinning, and he is directly against the idea that it is simply part of life.

What is a sluggish thyroid?

It is his own term for a thyroid underperforming even when the blood test reads normal, which he says happens because the TSH range is so wide.

Why does he call the thyroid the gas pedal?

It is his image for why the thyroid affects nearly every area of the body. You can be in the car and unable to press the pedal, running in neutral.

Look at the list, then the label
