Patient: I have been taking 131 iodine for 10 days now, and in the past few days I have had a slight swelling and some stiffness in my calf area. Is there any way to make this tautness disappear? In terms of diet, apart from seafood and iodine-containing foods that I cannot eat, I would like to ask if I can eat any of these foods? (soybeans, beans, peanuts (raw), lotus root, lettuce, longan, grapes, milk, chicken, duck), the above mentioned foods can not be eaten or I did not mention but also can not be eaten, I hope that Dr. Zhang you can be patient to reply to, because there are personally called to the hospital to take the medicine to consult the hospital, but the doctors there are perfunctory so very helpless, in order to do not want to affect the mood of the theory did not talk to them, and can only now I can only put my hope on you now. We can’t buy non-iodized salt here, so I can only take iodized salt and fry it at high temperature for consumption, do you think it will work? Can I color and perm my hair after taking 131 iodine for 2 weeks? Will there be any adverse effects? Hospital experts: oral iodine-131 treatment of hyperthyroidism, the whole body by the amount of exposure is not as large as a chest X-ray fluoroscopy exposure, iodine-131, more than 90% of the beta ray, will not penetrate out of the skin to irradiate others, a small amount of gamma ray will be out of the skin to irradiate others, but the amount is very small, and will not produce a definite harm (deterministic effect), so adults try to minimize exposure to you outside of the contact is no. What to worry about. Children because of the ray is more sensitive, 1 month is best not to close contact, especially do not cuddle sleep, try to let the children do not occur deterministic effects, but also to reduce the random effect. 1, the feeling in the calf has nothing to do with taking iodine-131, you can eat some potassium-rich fruits oranges, bananas may improve. 2, you can eat all those foods you mentioned. 3, the iodine diet can be prohibited for 1 month, your current measures are correct, 1 month later, in addition to try not to eat kelp, nori, other than as normal people. 4.Hair coloring has nothing to do with the treatment of hyperthyroidism, but you need to avoid the damage of the chemicals in it.
