Low urinary iodine can be treated in the following ways: 1. The body eats more iodine-containing foods in daily life, such as seaweed, salted fish and other seafood, which can replenish the iodine needed by the body. 2. If necessary, the body can take medication to stimulate the release of thyroid hormones in the body, thus alleviating the symptoms of low urinary iodine. Low urinary iodine also means that the iodine content in the body is too low, which can easily lead to symptoms of hypothyroidism, and timely supplementation of thyroid hormones can alleviate this situation. 3. Vitamin supplementation. Iodine is one of the essential vitamins for the human body. Proper supplementation of vitamins can maintain the endocrine balance of the human body, and can also try to alleviate the symptoms of iodine deficiency and effectively promote the body’s ability to absorb iodine.
