Which condition can result from overhydration and includes symptoms such as confusion and nausea?

• A. Hyponatremia due to dehydration
• B. Hyponatremia, confusion, nausea
• C. High blood sugar spikes
• D. Dehydration signs worsening

Answer: (B)

Overhydration dilutes the sodium in your blood, leading to hyponatremia. When sodium levels drop, brain cells swell, which can produce confusion and nausea as the primary symptoms. This combination— hyponatremia with neurologic symptoms like confusion and GI symptoms like nausea—fits what happens after drinking too much water and not enough electrolytes. The other options don’t align with this scenario: high blood sugar spikes aren’t caused by overhydration, and worsening dehydration means losing too much fluid rather than having too much, so those symptoms wouldn’t pair with overhydration. In this context, the important idea is that excessive water intake can create a dangerous electrolyte imbalance, so hydration should be balanced and guided by thirst and activity rather than forced consumption.
