Your thyroid—a small, butterfly-shaped gland in your neck—plays a crucial role in regulating energy, metabolism, and overall well-being. When it’s not functioning properly, it can lead to a variety of symptoms that may seem unrelated at first. If you’ve been feeling “off” lately, your thyroid could be to blame.

Here are 8 signs you might have a thyroid issue:

1. Unexplained Fatigue

Feeling exhausted even after a full night’s sleep? Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can impact your energy levels, making it difficult to stay awake during the day.

2. Weight Fluctuations

A sudden, unexplained weight gain may indicate hypothyroidism, while unintentional weight loss can be a sign of hyperthyroidism. If your diet and exercise habits haven’t changed but your weight is shifting, your thyroid may be struggling to regulate your metabolism.

3. Mood Changes & Brain Fog

Depression, anxiety, irritability, or difficulty concentrating are common signs of thyroid imbalances. Hypothyroidism is often linked to low mood and sluggish thinking, while hyperthyroidism can cause restlessness or nervousness.

4. Hair Thinning & Dry Skin

Hair loss, thinning eyebrows (especially the outer third), brittle nails, and persistently dry skin can indicate thyroid dysfunction. This happens because your thyroid hormones directly impact hair and skin cell renewal.

5. Sensitivity to Temperature

Do you always feel cold, even when others are comfortable? Hypothyroidism can slow your metabolism, making it harder to stay warm. On the flip side, hyperthyroidism can make you feel unusually hot or sweaty.

6. Digestive Changes

Frequent constipation is a common symptom of hypothyroidism, while diarrhea or frequent bowel movements may point to hyperthyroidism.

7. Changes in Heart Rate

An underactive thyroid can slow your heart rate, leading to fatigue and dizziness, while an overactive thyroid may cause a rapid or irregular heartbeat.

8. Puffy Face, Swelling, or Hoarseness

Hypothyroidism can lead to fluid retention, making your face appear puffy. You might also experience hoarseness or swelling in the neck due to an enlarged thyroid (goiter).

When to Get Tested for Thyroid Issues

If you recognize several of these symptoms, it’s worth talking to your doctor about thyroid testing. A simple blood test measuring TSH, Free T3, and Free T4 can help determine if your thyroid is functioning properly. Catching an imbalance early can help prevent long-term health complications and improve your overall well-being.

Your health is worth prioritizing—listen to your body, and don’t ignore the signs!
