As we at Podiatry Center of New Jersey kick off Thyroid Awareness Month this January, we’re shining a light on a small, butterfly-shaped gland that carries a massive responsibility. Most people know the thyroid for its role in metabolism, weight, and energy levels. However, you might be surprised to learn that some of the most telling signs of a thyroid imbalance appear as far away from your neck as possible.
1. Persistent Cold Feet
Do you find yourself wearing wool socks in the middle of summer? While poor circulation can have many causes, hypothyroidism is a common culprit. When thyroid hormone levels are low, your body’s basal metabolic rate drops, and it prioritizes keeping your core organs warm, which often leaves your hands and feet feeling like ice.
2. Cracked Heels
If you are slathering on lotion but your heels remain deeply cracked and dry, it might not just be the winter air. Thyroid hormones help regulate sweat glands and the natural oils in your skin. When the thyroid is sluggish, skin cell turnover slows down, which can lead to dry, flaky skin that often results in painful fissures on the heels.
3. Swelling and Puffiness
Have you noticed your shoes feeling tighter by the end of the day? Hypothyroidism can cause a specific type of swelling known as myxedema.
This is basically a buildup of complex sugars in the skin tissues that causes the feet and ankles to look puffy. Unlike typical edema, this swelling often doesn’t leave an indentation when you press on it.
4. Yellowish Calluses
A lesser-known sign of thyroid trouble is a change in skin pigment. The thyroid is responsible for converting beta-carotene into Vitamin A. If your thyroid isn’t functioning correctly, beta-carotene can build up in the body and give the thick skin on the soles of your feet or your calluses a distinct yellowish tint.
5. Brittle Toenails
Just as thyroid issues can cause hair loss, they can also affect the health of your nails. If your toenails have become brittle, slow-growing, or are frequently crumbling and splitting, it may be a sign of an underlying hormonal deficiency.
The Thyroid and Your Feet
Your feet are often the canary in the coal mine for systemic health issues. If you’ve noticed a combination of these symptoms, especially alongside fatigue or brain fog, this January is the perfect time to speak with your doctor.
A simple blood test to check your TSH (Thyroid Stimulating Hormone) levels can provide the clarity you need to get back on your feet.
