What are the potential risks of excessive sodium intake?

Excessive sodium intake is primarily associated with high blood pressure, also known as hypertension. When sodium levels in the body rise, it can lead to an increase in blood volume because sodium attracts water, which puts additional strain on blood vessels. This increased pressure can damage the arteries over time and contribute significantly to the development of cardiovascular diseases, including heart attack and stroke.

High blood pressure itself is often referred to as a "silent killer" because it can develop without any noticeable symptoms, yet it poses serious health risks. Additionally, chronic hypertension can lead to further complications, such as heart failure and kidney damage over time. This is why it is crucial for individuals, especially those with risk factors for heart disease, to monitor and manage their sodium intake.

While reduced kidney function can be a consequence of high sodium intake, it is more commonly a result of existing kidney issues exacerbated by high blood pressure. Therefore, the direct link between high sodium intake and high blood pressure, along with its association with cardiovascular disease, clearly supports the correctness of this choice.
