20 Sneaky Signs of Thyroid Problems


Before dwelling on the 20 sneaky signs of a thyroid problem, let us help you understand its role. The thyroid gland is a small butterfly-shaped organ at the base of the neck. It produces hormones that play a critical role in regulating metabolism, growth, and development in the body.

Triiodothyronine (T3) and thyroxine (T4), the thyroid gland’s two main hormones, are released into the bloodstream and carried to all of the body’s cells. These hormones are crucial for controlling the body’s metabolism, which affects how rapidly the body uses energy and how quickly calories are burned.

The pituitary gland controls the thyroid gland, located at the base of the brain. Thyroid-stimulating hormone (TSH), which is produced by the pituitary gland, instructs the thyroid gland to manufacture and release thyroid hormones. The amount of TSH produced by the pituitary gland is regulated by a feedback mechanism that ensures the body has the right amount of thyroid hormones.

Health issues can result from the thyroid gland producing too many or too few thyroid hormones. For instance, hyperthyroidism, an overactive thyroid gland, can result in uneasiness, rapid heartbeat, and weight loss.

In contrast, hypothyroidism (an underactive thyroid) can result in symptoms like weight gain, lethargy, and sadness. We have covered the hidden symptoms of thyroid issues below.

20 Sneaky Signs of A Thyroid Problem

Here are the sneaky signs of thyroid problems and how they can affect the body:

1. Fatigue:

An underactive thyroid gland (hypothyroidism) can cause fatigue, making it difficult to complete daily activities.

2. Weight gain or difficulty losing weight:

Hypothyroidism can cause weight gain due to a slower metabolism, while hyperthyroidism can cause weight loss due to increased metabolism.

3. Cold & Heat intolerance:

Hypothyroidism can cause a decrease in body temperature regulation, leading to cold and heat intolerance.

4. Dry skin:

Hypothyroidism can cause dry, itchy skin due to a lack of moisture.

5. Brittle nails:

Hypothyroidism can cause brittle, weak nails that break easily.

6. Hair loss:

Both hyperthyroidism and hypothyroidism can cause hair loss, often noticeable as thinning of the hair.

7. Mood swings:

Both hyperthyroidism and hypothyroidism can cause mood swings, such as anxiety, irritability, and depression.

8. Irregular menstrual cycles:

Hypothyroidism can cause irregular periods or heavy menstrual bleeding, while hyperthyroidism can cause light or infrequent periods.

9. Muscle weakness:

Hypothyroidism can cause muscle weakness and difficulty with physical activity.

10. Joint pain:

Hypothyroidism can cause joint pain, stiffness, and swelling.

11. Constipation:

Hypothyroidism can cause constipation due to slower digestion.

12. Diarrhea:

Hyperthyroidism can cause diarrhea due to faster digestion.

13. Increased heart rate:

Hyperthyroidism can cause an increase in heart rate, which can lead to heart palpitations and an irregular heartbeat.

14. Tremors:

Hyperthyroidism can cause tremors, which are involuntary muscle movements.

15. Changes in appetite:

Both hyperthyroidism and hypothyroidism can cause changes in appetite, such as increased or decreased appetite.

16. Insomnia:

Hyperthyroidism can cause insomnia, making it difficult to fall or stay asleep.

17. Memory problems:

Both hyperthyroidism and hypothyroidism can cause memory problems, such as difficulty concentrating and forgetfulness.

18. Swelling in the neck:

An enlarged thyroid gland, also known as a goiter, can cause swelling in the neck and difficulty swallowing or breathing.

19. Hoarse voice:

An enlarged thyroid gland or nodules on the thyroid can cause a hoarse voice or difficulty speaking.

20. Vision problems:

Graves’ disease, a type of hyperthyroidism, can cause vision problems such as bulging eyes, double vision, and sensitivity to light.

How to Avoid the Sneaky Signs of Thyroid Problems?

While there’s no sure way to completely avoid the sneaky signs of thyroid problems, there are some steps you can take to reduce your risk or catch any issues early on:

Get regular check-ups:

Annual check-ups with your healthcare provider can help catch any potential thyroid problems early on.

Know your family history:

If thyroid problems run in your family, be sure to inform your healthcare provider.

Maintain a healthy diet:

Eating a well-balanced diet rich in fruits, vegetables, and lean proteins can help support thyroid function.

Get enough iodine:

Iodine is important for thyroid function, so you must include iodine-rich foods like seafood and seaweed in your diet.

Manage stress:

Stress can affect thyroid function, so managing stress through practices like meditation, yoga, or therapy can help keep your thyroid healthy.

Exercise regularly:

Regular exercise can help support thyroid function and reduce your risk of developing hypothyroidism.

Avoid smoking:

Smoking can increase your risk of developing thyroid problems, so avoiding smoking is important for overall thyroid health.

Monitor any changes in your body:

Discuss any changes in your weight, energy level, mood, or menstrual cycle with your healthcare provider.

Hyperthyroidism & Hypothyroidism

The two main types of thyroid problems are hyperthyroidism and hypothyroidism.


This is a condition in which the thyroid gland produces too much thyroid hormone. As a result, the body’s metabolism speeds up, causing symptoms such as:

  • Rapid or irregular heartbeat
  • Nervousness or anxiety
  • Tremors
  • Weight loss despite increased appetite
  • Heat intolerance and excessive sweating
  • Fatigue and muscle weakness
  • Trouble sleeping
  • Vision problems such as double vision or bulging eyes
  • Thinning hair and brittle nails
  • Irritability and mood swings

Graves’ disease, an autoimmune condition in which the body creates antibodies that stimulate the thyroid gland to release excessive amounts of the hormone, is the most frequent cause of hyperthyroidism. Thyroid nodules, thyroiditis, and specific drugs are a few additional reasons for hyperthyroidism.


This is a condition in which the thyroid gland produces insufficient thyroid hormone. This slows down the body’s metabolism, causing symptoms such as:

  • Fatigue and sluggishness
  • Weight gain or difficulty losing weight
  • Cold intolerance and feeling cold all the time
  • Dry skin and hair
  • Constipation
  • Brittle nails and hair loss
  • Depression and irritability
  • Memory problems and trouble concentrating
  • Heavy or irregular menstrual periods

The most common cause of hypothyroidism is an autoimmune disorder called Hashimoto’s thyroiditis. Other causes of hypothyroidism include iodine deficiency, radiation therapy, thyroid surgery, and certain medications.

Diagnostic Tests for Thyroid Problems

Several diagnostic tests can be used to identify thyroid problems. The most commonly used tests are:

TSH (thyroid-stimulating hormone) test:

This test measures the level of TSH in the blood, produced by the pituitary gland, and stimulates the thyroid gland to produce hormones. High levels of TSH may indicate an underactive thyroid (hypothyroidism), while low levels of TSH may indicate an overactive thyroid (hyperthyroidism).

Thyroid hormone tests:

These tests measure the levels of the thyroid hormones T4 and T3 in the blood. Low levels of these hormones may indicate hypothyroidism, while high levels may indicate hyperthyroidism.

Thyroid antibody tests:

These tests measure the levels of antibodies that target the thyroid gland. High levels of these antibodies may indicate autoimmune thyroid diseases, such as Hashimoto’s thyroiditis or Graves’ disease.


This imaging test uses sound waves to create images of the thyroid gland. It can help detect any nodules or abnormalities in the gland.

Fine-needle aspiration biopsy:

This test involves inserting a needle into a thyroid nodule to collect a sample of cells for examination under a microscope. It can help determine whether the nodule is benign (non-cancerous) or malignant (cancerous).
