Which electrolyte imbalance is associated with confusion and lethargy in patients with ETOH abuse?

Hyponatremia is indeed associated with confusion and lethargy, and this can be particularly relevant in patients who abuse alcohol. In alcohol use disorder, patients often experience poor nutritional intake and electrolyte imbalances, which can lead to low sodium levels in the blood.

When sodium levels drop below the normal range, it can result in cerebral edema due to the osmotic shifts that occur in the brain, leading to neurological symptoms such as confusion, lethargy, seizures, and, in severe cases, coma. This is because sodium is crucial for maintaining osmotic balance and proper neurological function.

In the context of alcohol use, these symptoms may be exacerbated by the additional factors such as dehydration and accompanying liver dysfunction, which further impact electrolyte balance. Addressing hyponatremia in these patients is critical to alleviate confusion and improve overall mental status.

Other electrolyte imbalances mentioned do not typically present with confusion and lethargy as the primary symptoms in the context of ETOH abuse. For instance, hypercalcemia and hypernatremia may present with different sets of symptoms, while hypokalemia is more often associated with muscle weakness, cramps, or cardiac issues rather than the neurological changes seen with low sodium levels.
