Iodine poisoning occurs when a person consumes excessive amounts of iodine, either through dietary sources, supplements, or accidental exposure to iodine-containing solutions. While iodine is essential for proper thyroid function and overall health, too much can lead to serious medical complications. Understanding the signs, treatment options, and prevention methods is crucial for maintaining safe iodine levels.
This comprehensive guide explores the key aspects of iodine poisoning, including its symptoms, treatment approaches, and preventive measures to help you stay informed and safe.
