What physiological process characterizes the condition known as hyponatremia?
Answer
Excessive water intake dilutes sodium levels in the blood, causing cells to swell
Hyponatremia occurs when excessive water intake lowers the sodium concentration in the blood to dangerously low levels. Sodium is a critical electrolyte for nerve and muscle function. When its concentration drops, water moves via osmosis from the blood into cells, leading to cellular swelling, which can have severe medical consequences.
