However, early detection of thyroid dysfunction signs allows for quick and effective management. In this article, we will explore the early warning signs of a thyroid disorder, the differences between hypothyroidism and hyperthyroidism, and the steps to get a reliable diagnosis.

What Is the Thyroid and What Does It Do?

The thyroid is a small, butterfly-shaped gland located at the base of the neck. It produces hormones (T3 and T4) that regulate metabolism, body temperature, heart rate, and influence many bodily functions.

According to INSERM (the French National Institute of Health and Medical Research), thyroid disorders affect about 10% of the French population, with a higher prevalence in women and older people.

Common Symptoms of Thyroid Dysfunction

The signs of a thyroid malfunction are often non-specific, which makes them difficult to identify. Here are the most common ones:

• Persistent Fatigue

  • Fatigue that doesn't go away despite getting good sleep can signal hypothyroidism.

• Unexplained Weight Gain or Loss

  • Hypothyroidism: A tendency to gain weight.

  • Hyperthyroidism: Rapid weight loss despite a good appetite.

• Mood Swings

  • Anxiety, depression, irritability... Thyroid hormones also influence emotional balance.

• Skin, Nail, and Hair Problems

  • Dry skin, brittle nails, hair loss.

  • Moist skin and thin hair in the case of hyperthyroidism.

• Menstrual and Fertility Issues

  • Irregular cycles or unexplained infertility may be linked to a thyroid imbalance.

• Intolerance to Cold or Heat

  • Pronounced sensitivity to cold: hypothyroidism.

  • Hot flashes: hyperthyroidism.

Hypothyroidism vs. Hyperthyroidism: Two Opposing Disorders

Hypothyroidism: A General Slowdown

Characterized by an insufficient production of thyroid hormones. Symptoms include:

• Extreme fatigue

• Weight gain

• Constipation

• Slow heart rate

• Depression

Reference Study: A study published in The Journal of Clinical Endocrinology & Metabolism shows that 4-6% of adults suffer from hypothyroidism, often undiagnosed.

Hyperthyroidism: The Body in Overdrive

Excess thyroid hormones. Symptoms include:

• Rapid weight loss

• Palpitations

• Tremors

• Nervousness

• Insomnia

Real-Life Example: Claire, 38, recounts: "I thought I was suffering from burnout, but it was my thyroid going into overdrive. A simple hormone test changed everything."
