What dietary recommendations should be followed by patients with heart failure?

Patients with heart failure are strongly advised to follow a low sodium diet. This is primarily because sodium can lead to fluid retention, which exacerbates the symptoms of heart failure. In heart failure, the heart's ability to pump blood efficiently is compromised, often resulting in congestion and edema. High sodium intake increases intravascular volume, placing additional strain on an already weakened heart and potentially leading to worsening symptoms, including shortness of breath and swelling in the legs and abdomen.

By adhering to a low sodium diet, patients can help manage their blood pressure and reduce fluid retention, ultimately improving their heart function and quality of life. This dietary adjustment is an essential part of comprehensive heart failure management alongside medication and lifestyle changes. Other dietary recommendations, while potentially beneficial for overall health, do not target the specific complications associated with heart failure in the same way that reducing sodium does.
