From the Research
High sodium levels can be caused by various factors, including excessive sodium intake, dehydration, certain medical conditions, and hormonal disorders, as highlighted in a 2020 study published in the International Journal of Molecular Sciences 1.
Causes of High Sodium Levels
Some of the key reasons for high sodium levels include:
- Excessive sodium intake from consuming too many salty foods or supplements
- Dehydration from not drinking enough water, excessive water loss through sweating, vomiting, diarrhea, or certain medications like diuretics
- Medical conditions such as diabetes insipidus, which affects kidney function and water regulation
- Hormonal disorders affecting aldosterone, a hormone that regulates sodium and water balance
- Kidney disease, which can disrupt sodium balance
- Certain medications like corticosteroids, which can also disrupt sodium balance
Recent Study Findings
A 2018 study published in the Journal of Clinical Hypertension found that high sodium intake increases blood pressure and risk of kidney disease, confirming the negative effects of excessive sodium intake on health outcomes 2.
Treatment and Prevention
Treatment typically involves addressing the underlying cause and carefully rehydrating with appropriate fluids, as well as monitoring sodium levels and maintaining adequate daily water intake to prevent hypernatremia 1. In severe cases, intravenous fluids may be necessary to gradually lower sodium levels, as correcting high sodium too quickly can cause dangerous brain swelling. Regular blood tests can monitor sodium levels in those at risk, and maintaining adequate daily water intake is important for prevention.
