What should patients with hyperthyroidism not eat?

1. Absolute avoidance of iodine

Iodine is the main raw material for producing thyroid hormone. Excessive iodine intake can lead to aggravation or delayed recovery of hyperthyroidism. We should absolutely avoid iodine

① Avoid eating all seafood and try to eat iodized salt. The daily intake of iodine for normal people is 150 micrograms/day, but for patients with hyperthyroidism it should be less than 50 micrograms/day. We divide iodine-containing foods into three levels. The first category contains thousands to tens of thousands of micrograms of iodine per 100 grams, including: kelp (kelp), nori (seaweed), moss, jellyfish, etc. The second category contains hundreds to thousands of micrograms of iodine per 100 grams, including : Sea crabs, sea shellfish, etc. The third category contains tens to hundreds of micrograms of iodine per 100 grams, including: marine fish, shrimp, etc. The iodine content of iodized salt generally contains about 20-30 micrograms per gram of salt. Therefore, all seafood is high in iodine for patients with hyperthyroidism, and iodized salt should be avoided as much as possible.

②Reduce opportunities to eat out. The salt used in restaurants is usually iodized salt, and we cannot guarantee that the previous customer ordered seafood in the same wok. A large amount of iodine will inevitably be mixed into the food during the cooking process.

③Avoid using iodine-containing medicines and cosmetics. Drugs include: the antiarrhythmic drug amiodarone; contrast agents required for enhanced CT; iodine used for disinfection; iodine-containing vitamin tablets (including Centrum, Jinselkang, etc.); cosmetics, etc. include: products containing seaweed ingredients Facial cleanser, shampoo, facial mask, foot bath powder, etc.

④Avoid traveling to coastal cities. The specialty of coastal cities is seafood. It is unavoidable to consume a large amount of iodine when traveling and dining. It can even be said that there is a lot of iodine in the sea breeze. In short, in life (what you eat, use, and play), you should try your best to avoid excessive intake of iodine, and "absolutely avoid iodine."

If hyperthyroidism occurs after pregnancy, as long as TRAb is positive, iodine must be avoided. Graves' disease hyperthyroidism means desperately absorbing iodine and desperately producing thyroid hormones, resulting in excess hormone, so iodine (raw material) cannot be supplemented. The fetal thyroid gland has not yet developed, so what it really needs is the mother's FT4 (finished product). As long as the mother's thyroid function is normal and Ft4 is sufficient, the fetus will not be iodine deficient. Even if the thyroid hormone level of the mother with hyperthyroidism drops due to the effects of hyperthyroidism drugs in the later period, Euthyrox and other products (L-T4) should be supplemented, which are finished products rather than raw material iodine.

Patients with hyperthyroidism should also pay attention to the following dietary aspects: ① Exciting foods (such as spicy food, coffee, strong tea, etc.): Hyperthyroidism patients themselves may have symptoms such as palpitation, fear of heat, excitement, and insomnia. Exciting symptoms and irritating foods can aggravate the above symptoms and should be avoided until thyroid function is fully controlled. Also, certain cold medicines, such as Tylenol. The instructions for Baifuning and others say "use with caution in patients with hyperthyroidism". That's because these drugs contain pseudoephedrine, which can cause the heart rate to increase. They can be taken after thyroid function is controlled. ②Calcium: Hypermetabolism is one of the characteristics of hyperthyroidism. Therefore, middle-aged and elderly patients with osteoporosis should pay attention to supplementing calcium and vitamin D. ③ Vitamins: Patients with hyperthyroidism are very likely to be deficient in vitamins. In addition, hyperthyroidism itself and the application of antithyroid drugs in the treatment of hyperthyroidism can cause leukopenia and require additional vitamin supplements.

2. Avoid infection

The total number of white blood cells and granulocytes in patients with hyperthyroidism is low, which can easily lead to infection. If infection occurs, controlled hyperthyroidism will relapse or worsen, or even lead to a hyperthyroid crisis. Studies have shown that infection can increase TRAb and prolong the course of hyperthyroidism. Therefore, we must learn to prevent various infections, and once signs of infection are discovered, we should treat them as soon as possible. It is not recommended to rely on your own resistance to fight. ?

3. Pay attention to rest

Patients with hyperthyroidism should not stay up late frequently and engage in strenuous activities such as long-distance running, swimming, mountain climbing; those with severe illness should rest quietly or even rest in bed. In addition, some patients with hyperthyroidism may be accompanied by exophthalmos, which causes paralysis of the extraocular muscles, making them prone to visual fatigue and bulging eyeballs. After reading books, newspapers, and especially watching TV for a long time, you often feel swelling and pain in the eyeballs. Therefore, patients with this disease should pay attention to reducing eye irritation and visual fatigue.
