The thyroid is a small gland located in the neck, and it plays an important role in regulating your body’s metabolism. However, when it is not functioning properly, it can cause a range of symptoms that can be difficult to diagnose.

Here are 30 indications that your thyroid may not be functioning correctly.

1. Weight Gain or Weight Loss

A change in weight, whether gaining or losing, can be an indication of an underactive or overactive thyroid. The thyroid gland regulates metabolism, and when it is not functioning correctly, it can cause weight issues.

2. Fatigue

If you are consistently feeling tired or fatigued, it could be an indication of an underactive thyroid. When the thyroid hormone levels are too low, it can cause fatigue.

3. Hair Loss

The thyroid gland plays an essential role in hair growth. An underactive or overactive thyroid can lead to hair loss or thinning hair.

4. Dry Skin and Hair

An underactive thyroid can cause dry skin and hair. The thyroid hormone regulates the body’s metabolism, and when it is not functioning correctly, it can lead to dryness.

5. Irregular Menstrual Cycles

The thyroid gland plays a critical role in the menstrual cycle. When the thyroid is not functioning correctly, it can lead to irregular cycles, heavy or light bleeding, or even infertility.

6. Difficulty Sleeping

If you are having trouble sleeping, it can be an indication of an overactive thyroid. The thyroid hormones help regulate the body’s metabolism, and when they are too high, it can cause insomnia.

7. Mood Swings

An imbalance in thyroid hormones can lead to mood swings, anxiety, and depression.

8. Weakness or Tremors in Muscles

An overactive thyroid can cause muscle weakness or even tremors. It is because the thyroid hormone plays an important role in the proper functioning of muscles.

9. Constipation

An underactive thyroid can cause constipation. The thyroid hormone regulates digestion, and when it is low, it can slow down the digestive system.

10. Cold Intolerance

When the thyroid hormone levels are low, the body’s temperature regulation can be affected, making the person more sensitive to cold temperatures.

11. Heat Intolerance

On the other hand, an overactive thyroid can cause a person to be more sensitive to heat.

12. Heart Palpitations

An overactive thyroid can cause an increased heart rate or abnormal heart rhythms, leading to palpitations.

13. High Blood Pressure

An overactive thyroid can cause high blood pressure due to an increased heart rate and constriction of blood vessels.

14. Low Blood Pressure

Low thyroid hormone levels can cause the heart rate to slow down, leading to low blood pressure.

15. High Cholesterol

An underactive thyroid can cause high cholesterol levels and increase the risk of heart disease and stroke.

16. Weakened Immune System

The thyroid gland plays a crucial role in the functioning of the immune system. An underactive thyroid can weaken the immune system, making the person more susceptible to infections.

17. Infertility

Thyroid hormone imbalances can affect the menstrual cycle and cause infertility.

18. Muscle and Joint Pain

An underactive thyroid can cause muscle and joint pain and stiffness. It is because thyroid hormones play an important role in the proper functioning of muscles and joints.
