Fatigue that coffee doesn't fix. Feeling cold when everyone else is comfortable. Hair thinning, dry skin, brain fog, or weight that won't budge. These symptoms are easy to blame on stress or getting older, but they can also be signs that your thyroid isn't working the way it should. Here's what to know about thyroid health and Hashimoto's thyroiditis, and how thyroid care at The Skin Clinic can help.
What does your thyroid do?
Your thyroid is a small, butterfly-shaped gland at the front of your neck. It makes hormones (mainly T4, which your body converts into active T3) that set the pace for metabolism, energy, body temperature, heart rate, mood, digestion, skin and hair. When thyroid hormone runs low, called hypothyroidism, many of those systems slow down.
What is Hashimoto's thyroiditis?
Hashimoto's is an autoimmune condition in which the immune system attacks the thyroid. Over time, the gland can lose its ability to make enough hormone. It's the most common cause of hypothyroidism in the United States, it's much more common in women, and it often runs in families. It can develop slowly over years, so symptoms may creep up gradually.
Common symptoms of an underactive thyroid
Fatigue and low energy
Feeling cold
Weight gain or trouble losing weight
Dry skin, brittle nails and hair thinning
Constipation
Brain fog, poor memory or low mood
Heavier or irregular periods
Muscle aches or joint stiffness
A puffy face or swelling at the front of the neck
Many of these overlap with perimenopause, low iron, PCOS, sleep problems and depression, which is why testing matters.
Which thyroid labs should you ask about?
TSH is the usual screening test, but on its own it doesn't always tell the whole story. A more complete evaluation can include:
TSH (thyroid-stimulating hormone)
Free T4 and free T3
Thyroid antibodies (TPO and thyroglobulin antibodies) to check for Hashimoto's
Metabolic markers such as blood sugar, insulin and cholesterol
Hormone levels, since estrogen, progesterone and testosterone can affect how you feel
Nutrient labs such as iron and ferritin, vitamin D and B12
Tip: biotin, a common ingredient in hair, skin and nail supplements, can interfere with thyroid lab results. Tell your provider if you take it, because you may need to pause it before testing.
How are hypothyroidism and Hashimoto's treated?
Hashimoto's can't be cured, but it is very manageable. Treatment often includes:
Thyroid hormone medication when your labs and symptoms show it's needed, carefully dosed and rechecked about 6–8 weeks after any change
Nutrition support for steady energy and blood sugar
Targeted supplements based on your lab results
Sleep and stress strategies, since both affect how you feel
Regular monitoring so your plan keeps up with your body
Getting the dose right matters. Too little medication leaves symptoms behind, while too much can cause a racing heart, anxiety, trouble sleeping or, over time, bone loss.
Still tired on thyroid medication?
If you're already being treated but still don't feel like yourself, the cause could be your dose, when or how you take your medication (for example with coffee, calcium or iron), low nutrient levels, other hormone changes, or something unrelated to your thyroid. A careful review of your labs and history can help find the answer.
When to see an endocrinologist
Some thyroid conditions are best managed by a specialist, including an overactive thyroid (hyperthyroidism or Graves' disease), a lump or swelling in your neck, thyroid nodules or cancer, and thyroid disease during pregnancy. Seek urgent care for a very fast or irregular heartbeat, chest pain, fainting or severe confusion.
