Symptom 3: Fatigue and Weakness
Fatigue and weakness in the context of hypernatremia are primarily a result of cellular dehydration. As blood sodium levels rise, water is drawn out of cells and into the bloodstream via osmosis, leading to a decrease in intracellular fluid volume. This dehydration impairs the normal functioning of cells, including those of the muscles and nerves, contributing to sensations of weakness and exhaustion.
Additionally, the body’s compensatory mechanisms in response to hypernatremia, such as increased water intake and urine production, can further exacerbate feelings of fatigue. The energy required for these physiological responses places additional stress on the body, leaving the individual feeling more tired and weak.
Treatment may involve the careful administration of fluids to rehydrate the body and restore the sodium balance. In some cases, it may be necessary to adjust medications or manage other medical conditions contributing to the development of hypernatremia.
If left untreated, hypernatremia can lead to severe complications, including neurological issues, seizures, coma, and even death. Thus, timely intervention and appropriate treatment are crucial to prevent these outcomes and improve the patient’s overall health. (3)
