Thyroid Interactions

Excessive seaweed consumption can impact thyroid function due to its high iodine content, potentially leading to hyperthyroidism or hypothyroidism, especially in individuals with pre-existing thyroid conditions.

Excessive consumption of seaweed, due to its high iodine content, can disrupt thyroid hormone production. This can lead to hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), depending on pre-existing thyroid conditions and iodine sensitivity. Symptoms may include weight changes, fatigue, changes in heart rate, anxiety, and goiter (enlarged thyroid gland). Individuals with pre-existing thyroid disorders, such as Hashimoto's thyroiditis or Graves' disease, are particularly vulnerable. Iodine-induced thyroid dysfunction can also affect individuals with autonomous thyroid nodules. The effect is related to the iodine content of the ingested seaweed.
