A high-sodium diet can lead to several serious health implications, including hypertension or high blood pressure. Excessive sodium intake can cause the body to retain fluid, increasing the strain on the heart and blood vessels. This may result in an elevated risk of cardiovascular diseases, including heart attacks and strokes. Furthermore, high sodium levels can negatively impact kidney function over time, contributing to the development of chronic kidney disease. Reducing sodium intake is essential for maintaining optimal health and preventing these associated risks.
