Fatigue

Persistent tiredness and lack of energy caused by slowed metabolism

Understanding Fatigue

Fatigue in hypothyroidism is one of the most common and debilitating symptoms. It results from the thyroid gland's inability to produce sufficient thyroid hormones, which are essential for regulating metabolism and energy production. This fatigue is often described as overwhelming and may not improve with rest.

What Causes Fatigue?

  • Reduced thyroid hormone levels slow cellular metabolism
  • Decreased energy production in mitochondria
  • Impaired oxygen utilization by cells
  • Disrupted circadian rhythm regulation
  • Associated depression and mood changes
