Which condition is likely to lead to fluid retention in patients with kidney disease?

Fluid retention in patients with kidney disease is closely associated with high sodium intake. Sodium plays a critical role in regulating fluid balance within the body. When a person consumes high levels of sodium, the kidneys may struggle to excrete the excess, leading to an accumulation of fluid. This is particularly problematic in individuals with kidney disease, as their ability to filter and eliminate excess fluid and electrolytes is compromised.

In conditions where kidney function is impaired, the intake of sodium can lead to increased blood volume because sodium attracts water. This effect can result in edema, increased blood pressure, and other related complications. Thus, managing sodium intake is crucial for individuals with kidney disease to help control and mitigate fluid retention and its associated risks.
