High sodium levels are described as?

High sodium levels in the bloodstream are referred to as hypernatremia. This condition occurs when there is an excessive concentration of sodium in the blood, usually due to a loss of water without an equivalent loss of sodium. This imbalance can lead to various health issues, including cell dehydration, neurological problems, and even seizures if not addressed.

In contrast, hyponatremia describes low sodium levels in the blood, which can also result in serious complications. The other terms, leukocytosis and thrombocytosis, refer to elevated white blood cell count and elevated platelet count, respectively, and are unrelated to sodium levels. Understanding the distinction between these terms is crucial for diagnosing and managing electrolyte imbalances effectively.
