What type of diet is recommended for patients with heart failure to manage fluid retention?

A low-salt diet is recommended for patients with heart failure primarily to manage fluid retention. In heart failure, the heart's ability to pump blood effectively is compromised, which can lead to fluid buildup in the body. Sodium, a key component of salt, contributes to water retention; thus, a high-sodium diet can exacerbate this condition. By reducing sodium intake, patients are less likely to retain excess fluid, which can help alleviate the workload on the heart, reduce symptoms such as swelling and shortness of breath, and improve overall quality of life.

In managing heart failure, dietary modifications focus on both fluid and sodium restriction to optimize heart function and minimize symptoms. This approach often includes emphasizing the intake of fresh fruits and vegetables, lean proteins, and whole grains while avoiding processed foods that are high in salt. Therefore, a low-salt diet is a cornerstone recommendation in the management of heart failure to help control fluid retention.
