Iodine toxicity, while rare, can occur when there is excessive intake or exposure to iodine. This can result from dietary supplements, medications containing iodine, or even overconsumption of iodized salt. Symptoms of iodine toxicity include nausea, diarrhea, abdominal pain, and in severe cases, it can lead to thyroid dysfunction. Toxicologists study these effects to set safe exposure limits and provide guidelines for iodine consumption.
