In Hubei College of Traditional Chinese Medicine treatment, taking Chinese medicine, the efficacy is not stable, the study task is aggravated, the condition is aggravated. Inquired about the 131 iodine treatment effect is better, may I ask: 18 years old can be treated in this way? What kind of preparation should be done before the treatment and how much does it cost (because her mom and dad are both laid-off workers)? Doctor：Iodine 131 treatment is available at the age of 18, and the youngest patient we have treated is less than 10 years old, depending on whether the condition requires such treatment. Generally speaking, adolescents and even children with hyperthyroidism preferred drug treatment, if the drug treatment is not effective, drug treatment has obvious side effects as well as repeated and can not adhere to the medication, it should be taken to iodine 131 treatment, the United States has been iodine 131 treatment as the first choice of treatment for adults with hyperthyroidism. Before treatment, it is necessary to abstain from eating iodine-containing food, stop using anti-thyroid medication and do the necessary examinations, and the total cost, including examinations, is within 2,000 yuan. Doctors: Complications may also occur with iodine 131 treatment, the most common being hypothyroidism, or hypothyroidism for short, which also requires long-term use of thyroid hormone supplementation medication. However, hypothyroidism is less harmful than hyperthyroidism, and the medication has no side effects and does not affect pregnancy and childbirth in adulthood.
