Limiting sodium intake reduces edema in heart failure?

Limiting sodium intake reduces edema in heart failure?

• A. True
• B. False
• C. Not related
• D. Only with diuretics

Answer: (A)

Limiting sodium intake reduces edema in heart failure because edema results from fluid retention driven by the body's response to reduced pumping ability. When sodium intake is high, the kidneys hold onto more sodium, and water follows, increasing extracellular fluid and causing edema and congestion. Reducing sodium lowers the amount of fluid the body tends to retain, which helps decrease edema and improves symptoms like breathlessness. This dietary change is a standard part of heart failure management and often makes diuretics more effective, though it can provide benefit on its own as well.
