This type of disease is an endocrine disorder, a condition that appears in children and is related to intelligence. It is a condition in which the body does not produce enough thyroxine and has a significant impact on the mental development of children. Generally, thyroxine replacement therapy is used for this condition. Some thyroid preparations are taken: sodium thyroxine and dry thyroid tablets. Both of these medications need to be taken for a long time and once they are stopped, the condition will recur. In addition to this, treatment should be carried out for 2-3 years before stopping the medication for one month for a review. If the test result is good, you can stop the medication. However, if there are signs of recurrence, you may need to take the medication for life. In terms of diet, you need to eat more iodine-rich dishes and add more iodized salt to your stir-fry.
