Hyperthyroidism should be careful not to use foods with high iodine content, but be careful with sweets. A moderate amount of sweets can replenish the spleen and replenish a lot of energy loss in the human body caused by hyperthyroidism, but too much sweets will damage the spleen, which is harmful to health and is not conducive to the rehabilitation of hyperthyroidism.
So you can eat sweets, but in moderation.
