Health Science | Prevention of water-borne high iodine hazards

1.What is a water source high iodine area?

Water-derived high iodine refers to the fact that due to the high iodine content in drinking water, people ingest iodine through drinking water that significantly exceeds the physiological needs of the human body for a long time, which may lead to high iodine thyroid disease in severe cases. Increased incidence of swelling, hyperthyroidism, hypothyroidism, and autoimmune thyroiditis.

Water-derived high iodine disease area refers to the area where people ingest excessive iodine through drinking water for a long time in a specific natural environment, causing diseases such as high iodine goiter.

2. Is excessive iodine intake harmful to human body?

High iodine, like low iodine, will endanger human health, causing adverse reactions such as high iodine goiter, and even iodine-derived hyperthyroidism. Excessive long-term iodine intake can lead to thyroid autoregulation imbalance and dysfunction, leading to goiter and hypothyroidism, and can also induce or promote the occurrence and development of autoimmune thyroiditis.

Excessive iodine intake during pregnancy can also damage fetal thyroid function and cause neonatal hypothyroidism.

3. How to prevent water-borne high iodine disease?

In areas with high iodine (disease) origin, the iodine content in drinking water is already very high, so people should not eat iodized salt. Local people should do the following: eat uniodized salt; stop or reduce the intake of iodine-containing food or iodine-containing health products; if the water has been changed, please drink qualified water to reduce the intake of iodine.

4. Is it harmful to consume iodized salt in water-derived high iodine areas?

Residents living in areas with high levels of iodine in water sources have ingested sufficient or even excessive amounts of iodine from drinking water. Therefore, eating iodized salt may lead to an increase in high-iodine goiter.

5. At present, there are 48 high iodine villages in water source found in Lintong District, they are:
