Our thyroid—a small, butterfly-shaped gland in the neck—has a big job. It controls how fast our body uses energy, keeps our temperature steady, and even affects our mood. But when it’s not working quite right, the signs can sneak up on you.
If you’ve been feeling “off” and can’t explain why, your thyroid could be part of the picture. Many Americans live with mild or undiagnosed thyroid issues, and while medication is sometimes needed, natural lifestyle changes can make a difference, too.
Let’s explore the top signs that your thyroid may need support—and what you can do to take care of it.
What Does the Thyroid Do?
The thyroid produces hormones—mainly T3 and T4—that influence nearly every cell in your body. When your thyroid is underactive (hypothyroidism), your body slows down. When it’s overactive (hyperthyroidism), things speed up. Both situations can cause uncomfortable symptoms.
According to the American Thyroid Association, around 20 million Americans have some form of thyroid disorder—yet up to 60% of them may not even know it.
Being informed is the first step to better health.
10 Signs Your Thyroid May Be Out of Balance
Here are some subtle (and not-so-subtle) signs that may suggest your thyroid isn’t functioning optimally.
1. Fatigue That Doesn’t Go Away
Feeling tired even after a full night’s sleep? Chronic exhaustion is one of the most common signs of hypothyroidism. When your metabolism slows, so does your energy.
2. Unexplained Weight Changes
- Gaining weight despite no major changes in your diet could suggest a sluggish thyroid.
- Rapid or unexpected weight loss might point to an overactive thyroid (hyperthyroidism).
3. Cold Hands and Feet
If you’re always chilly—even when others aren’t—it could mean your thyroid isn’t producing enough hormones to keep your temperature regulated.
4. Dry Skin and Hair
Low thyroid hormone levels can slow skin cell turnover, leading to dryness. Hair may become coarse or thin, and nails may break more easily.
5. Mood Changes or Brain Fog
Depression, anxiety, or difficulty concentrating could be tied to thyroid hormone imbalances. Your brain relies on a steady supply of these hormones to function smoothly.
6. Constipation or Digestive Issues
A slower metabolism can also slow down digestion. If you’re experiencing constipation often, your thyroid might be part of the cause.
7. Irregular Menstrual Cycles
Women with thyroid issues often notice changes in their cycle—heavier periods with hypothyroidism or lighter, shorter periods with hyperthyroidism.
8. Hoarseness or a Feeling of Fullness in the Neck
An enlarged thyroid (goiter) or nodules can cause throat discomfort or voice changes.
9. Thinning Eyebrows (Especially Outer Third)
This unusual symptom is often associated with hypothyroidism. If you’ve noticed your outer eyebrows getting sparse, it’s worth asking your doctor.
10. Slower Heart Rate or Palpitations
A slow heartbeat may signal hypothyroidism, while a racing heart can be linked to hyperthyroidism.
Note: Experiencing one or two of these symptoms doesn’t automatically mean you have a thyroid disorder. But several combined could warrant a closer look with your healthcare provider.
Natural Ways to Support Thyroid Health
If you suspect your thyroid needs support—or you just want to keep it functioning well—there are gentle lifestyle changes that may help.
1. Eat Iodine-Rich Foods
Iodine is essential for making thyroid hormones. While deficiencies are rare in the U.S. (thanks to iodized salt), some people may still benefit from more iodine-rich foods.
Good sources include:
- Seaweed (in moderation)
- Eggs
- Dairy products
- Iodized table salt
2. Support With Selenium and Zinc
These two minerals play important roles in hormone conversion and thyroid function.
Top sources:
- Brazil nuts (rich in selenium—just 1–2 a day is enough)
- Pumpkin seeds, legumes, and shellfish (for zinc)
3. Balance Your Stress
Chronic stress can negatively affect your thyroid. Supporting your adrenal glands through relaxation and good sleep helps protect hormone balance.
Stress-relief practices:
- Gentle walking or yoga
- Deep breathing or meditation
- Limiting screen time at night
4. Limit Highly Processed Foods
A diet heavy in processed, sugary, or fried foods can increase inflammation and stress the thyroid.
Instead, focus on:
- Whole fruits and vegetables
- Lean proteins (like chicken, fish, beans)
- Healthy fats (avocados, olive oil, nuts)
- Whole grains
5. Watch Your Gut Health
A healthy gut helps regulate your immune system—which is especially important because many thyroid conditions (like Hashimoto’s or Graves’) are autoimmune.
Tips for gut support:
- Eat probiotic-rich foods (yogurt, kefir, sauerkraut)
- Add fiber with fruits, veggies, and legumes
- Avoid unnecessary antibiotics
Should You Get Your Thyroid Checked?
Yes—especially if you relate to several of the symptoms above. A simple blood test can check your TSH (thyroid-stimulating hormone), T3, T4, and thyroid antibodies.
Ask your doctor about thyroid testing if you:
- Are over age 50
- Have a family history of thyroid problems
- Recently had a baby (postpartum thyroiditis is common)
- Are experiencing unexplained fatigue, weight changes, or mood shifts
Early detection makes management easier.
When Lifestyle Isn’t Enough
Natural strategies can support your thyroid—but they’re not always enough. If you’re diagnosed with a thyroid condition, your doctor may recommend medications such as levothyroxine.
Combining medication (when needed) with healthy habits is often the best approach.
Final Thoughts: Listen to Your Body
Your thyroid may be small, but it plays a powerful role in how you feel every day. Paying attention to subtle shifts in energy, mood, and physical changes can help you catch imbalances early.
And remember: supporting your thyroid doesn’t mean overhauling your life. Even small steps—like eating more nutrient-rich foods or managing stress—can go a long way.
