Difference Between a Healthy Thyroid and Hyperthyroidism 🦋 …

by

Hyperthyroidism occurs when the thyroid produces too many hormones. This overproduction accelerates metabolism and affects multiple body systems.

Common Causes:

  • Graves’ disease: An autoimmune condition causing overactivity.

  • Thyroid nodules: Overactive lumps in the thyroid.

  • Excess iodine: Rare, but too much iodine can stimulate hormone production.

  • Thyroid inflammation: Temporary overproduction after thyroiditis.
