Hypothyroidism patients can eat all the dishes except for things in the sea, such as seaweed, kelp and seafood, which cannot be eaten. Because the common cause of hypothyroidism is Hashimoto’s thyroiditis, and hypothyroidism caused by hyperthyroidism after iodine-131 treatment, or hypothyroidism caused by hyperthyroidism after thyroid surgery, these three cases can not eat things with high iodine content. However, there are some herbal teas, such as herbal teas made with cat’s claw and pig’s bone grass, which cannot be drunk because they contain high iodine and will further aggravate hypothyroidism. You should not stop taking the medication in the middle, nor should you increase or decrease the dosage on your own. You have to go for a yearly review of your thyroid function and adjust the dosage of Eugenol according to the results of your thyroid function. You should take Eugenol every morning on an empty stomach and eat breakfast only one hour after taking the medication.
