What thyroid disorders can result from chronically high iodine intake from kelp consumption?

Hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid).

Iodine is crucial for thyroid hormone production, but excessive, chronic intake disrupts the gland's delicate equilibrium. When iodine intake remains persistently high, it can lead to two opposing, detrimental outcomes affecting thyroid function. In one scenario, the excess iodine can suppress the thyroid gland's activity, leading to hypothyroidism, characterized by an underactive state. Conversely, the high load can stimulate the gland excessively, resulting in hyperthyroidism, where the gland becomes overactive. This duality of potential dysfunction makes monitoring crucial, especially for individuals with pre-existing thyroid vulnerabilities.
