Medical reports from Vietnam have highlighted the risks of severe hypokalemia resulting from untreated or mismanaged hyperthyroidism.

In one instance, a 25-year-old man in Dong Nai experienced sudden quadriplegia after stopping his hyperthyroidism medication. Medical intervention involving intravenous potassium and sodium chloride resolved the paralysis within hours.

In a separate case, a 41-year-old man in Hanoi was hospitalized with severe limb weakness. The patient had attempted to self-treat for perceived low calcium, but doctors determined the issue was actually hypokalemia caused by hyperthyroidism. Recovery required treating both the potassium deficiency and the underlying thyroid condition. Medical experts noted that the symptoms of low calcium and low potassium can be similar, which may lead to dangerous misdiagnoses.
