The Claim
Intravenous potassium supplementation rapidly reverses paralysis in thyrotoxic periodic paralysis, but administration carries a risk of rebound hyperkalemia and fatal arrhythmias.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Administering potassium intravenously stops muscle paralysis caused by an overactive thyroid, but it can also cause dangerously high potassium levels and life-threatening heart rhythm disturbances.
See the scientific wording
Intravenous potassium supplementation can rapidly reverse paralysis in thyrotoxic periodic paralysis, but must be administered cautiously to avoid rebound hyperkalemia and fatal arrhythmias.
Excess thyroid hormone makes muscle cells pull too much potassium from the blood into their interior, causing low blood potassium and muscle paralysis. Giving potassium intravenously restores blood potassium levels, allowing muscle cells to generate electrical signals again and regain strength. If too much potassium is given too quickly, blood potassium rises dangerously high, which can disrupt the heart's rhythm and cause sudden death.
What the research says
1 studyStudy: Pop-provoked paralysis: silent Graves’ disease presenting as thyrotoxic periodic paralysis
Giving potassium through an IV helped this man regain his muscle strength during a paralysis attack caused by an overactive thyroid. It worked quickly, and he didn’t have any dangerous side effects in this one case.
