Thyroid symptoms · New York & South Carolina
Thyroid symptoms often have more than one cause, and they’re rarely all checked at once.
If this sounds familiar, you’re in the right place.
- Cold hands and feet, all year
- Worn out however much you sleep
- Weight creeping up, same diet
- Thinning hair and dry skin
- Forgetful and slow to think
- On medication, still not right
If your body keeps telling you something’s off, it’s worth a closer look.

One thyroid number rarely tells the whole story.
How you feel also depends on nutrients, stress, your gut and your liver, and they’re rarely looked at together.
- 01
Thyroid
Your thyroid makes a hormone your body has to convert before it can use it. Several things affect how well that goes.
- 02
Nutrients
Iron, selenium, zinc and iodine help your thyroid make and use its hormone. If you’re low on them, you can feel colder, slower and foggier.
- 03
Stress
Under pressure for years? Long-term stress can slow the way your body puts thyroid hormone to work, turning your energy down with it.
- 04
Gut
Your gut absorbs the nutrients your thyroid relies on. When digestion struggles, your thyroid can end up short of what it needs.
- 05
Liver
Your liver does some of the work of turning thyroid hormone into the form your body uses, so how it’s working can play a part.
You’ve probably tried some of these.

You were right to keep asking. The answer usually takes a wider look.
Feeling tired and cold is a signal. Your thyroid is only part of the reason.
When you feel cold, tired and slow, it makes sense to look at the thyroid alone: one test, one number, maybe a change of dose. But how you feel depends on more than how much hormone your thyroid makes.
Your thyroid needs iron, selenium and iodine to make its hormone. Your gut and liver help turn it into the form your body uses, and long-term stress can slow that down. If one of these is off, you can feel colder, slower and more tired.
- What you feelCold, tired and foggy, most days
- What’s driving itYour body not converting enough thyroid hormone
- Where it startsLong-term stress, and low iron and selenium

Meet Dr. Anthony Alphonso and the Back to Wellness team.
We’re a functional medicine practice for people who’ve been told they’re fine but still don’t feel it. Anthony has been in practice since 2007.
It started with his son, whose eczema and gut trouble weren’t getting better with the usual treatment. Anthony went looking further than he’d been trained to, finished his functional medicine training in 2009, and watched his son’s health turn around. He’s been doing the same for patients ever since.

The questions everyone asks.
But my thyroid has already been tested.
That’s worth having. We also look at the nutrients, stress, gut and liver your thyroid relies on, which a standard check doesn’t usually cover, and we work alongside your physician.
But I don’t have time for this.
It starts with a 15-minute call, by phone or video. After that, coaching works around your week, all from home.
But will insurance cover it?
No. Our patients invest in the program directly, and we’ll walk you through the cost on your free call so nothing comes as a surprise.
But do I have to come off my thyroid medication?
No. Please don’t change your dose or stop anything on your own. We work alongside your physician, and any decision about medication stays between you and them.
But what if it’s something serious?
See your physician for a neck lump or swelling, trouble swallowing, or a racing heart with weight loss you can’t explain, shakiness or heat intolerance. Call 911 for trouble breathing.
