甲状腺功能亢进：两种必须避免的关键物质
摘要
本文介绍了hyperthyroidism（甲亢）患者必须避免的两种关键补充剂，因为摄入这些物质可能会危险地放大已经过度活跃的甲状腺功能。Berg 博士强调，碘含量高的食物和胆汁盐是任何甲状腺功能亢进患者需要重点关注的主要问题。
核心要点
- hyperthyroidism（甲亢）患者不应食用海藻或任何含碘产品
- 患有甲亢时，胆汁盐、胆汁提取物、牛胆汁以及胆囊配方产品也必须避免
- 碘会刺激甲状腺激素的产生，使已经过度活跃的甲状腺情况进一步恶化
- 胆汁盐会促进T4 to T3的转化，从而放大甲状腺活性
- 这些补充剂（iodine碘和胆汁盐）适用于甲状腺功能减退（甲减），而非甲亢患者
- 如果您对胆汁盐补充剂不熟悉，很可能您并未服用，这部分内容可能与您无关
详细内容
避免摄入碘
thyroid gland（甲状腺）在甲亢状态下已经过度运作，产生过量的甲状腺激素。碘是甲状腺激素合成的直接原料，因此额外摄入碘——包括通过海藻或海带摄入——会进一步刺激激素的产生，并加重症状。
避免服用胆汁盐
bile salts（胆汁盐）（也以牛胆汁、胆汁提取物的形式销售，或存在于胆囊支持配方中）在thyroid hormone conversion（甲状腺激素转化）中发挥作用。具体而言，它们促进非活性激素 T4 转化为活性激素 T3。在甲亢状态下，这一转化过程已在以较高速率进行。服用胆汁盐会进一步加速这一过程，使甲状腺活性升高至有害程度。
甲减与甲亢的区别
这两种物质作用于甲状腺功能谱的两个对立端：
- 在甲状腺功能减退（甲减，甲状腺功能低下）的情况下：碘和胆汁盐可能有益于支持偏低的甲状腺功能
- 在甲状腺功能亢进（甲亢，甲状腺功能过度活跃）的情况下：两者均须严格避免，因为它们会放大已经过度的甲状腺反应

Hyperthyroidism: Two Key Things to Avoid
Summary
This article covers two critical supplements that people with hyperthyroidism must avoid, as consuming them can dangerously amplify already overactive thyroid activity. Dr. Berg highlights iodine-containing foods and bile salts as the primary concerns for anyone with a hyperactive thyroid condition.
Key Takeaways
- People with hyperthyroidism should not consume seaweed or any iodine-containing products
- Bile salts, bile extracts, ox bile, and gallbladder formulas must also be avoided with hyperthyroidism
- Iodine stimulates thyroid hormone production, worsening an already overactive thyroid
- Bile salts increase the conversion of T4 to T3, amplifying thyroid activity
- These same supplements (iodine and bile salts) are appropriate and beneficial for hypothyroidism, not hyperthyroidism
- If you are unfamiliar with bile salt supplements, you are likely not taking them and this may not apply to you
Details
Avoid Iodine
The thyroid gland in a hyperthyroid condition is already working too hard, producing excessive thyroid hormone. Iodine is a direct building block of thyroid hormones, so consuming additional iodine — including through seaweed or kelp — will further stimulate hormone production and worsen symptoms.
Avoid Bile Salts
Bile salts (also sold as ox bile, bile extract, or found in gallbladder support formulas) play a role in thyroid hormone conversion. Specifically, they promote the conversion of the inactive hormone T4 into the active hormone T3. In a hyperthyroid state, this conversion is already occurring at an elevated rate. Taking bile salts would accelerate this process further, increasing thyroid activity to a harmful degree.
The Hypo vs. Hyper Distinction
These two substances operate on opposite sides of the thyroid spectrum:
- In hypothyroidism (underactive thyroid): iodine and bile salts may be beneficial to support low thyroid activity
- In hyperthyroidism (overactive thyroid): both must be strictly avoided as they amplify an already excessive thyroid response
