Weight Loss

Unintended weight loss despite normal or increased appetite

Understanding Weight Loss

Weight loss in hyperthyroidism occurs because excess thyroid hormones dramatically increase metabolic rate. The body burns calories much faster than normal, leading to unintended weight loss even when eating more than usual.

What Causes Weight Loss?

  • Increased metabolic rate (up to 60-100% elevation)
  • Increased calorie burning at rest
  • Enhanced fat and carbohydrate metabolism
  • Increased heat production
  • Gastrointestinal changes affecting nutrient absorption

When to Seek Medical Help

You should consult a thyroid specialist if you experience:

  • ⚠️Rapid unintended weight loss
  • ⚠️Weight loss accompanied by palpitations and anxiety
  • ⚠️Severe weight loss affecting health
  • ⚠️Weight loss with muscle weakness
