What advice should healthcare professionals give to patients with heart failure?
Healthcare professionals should not routinely advise patients with heart failure to restrict their salt or fluid consumption. However, they should ask their patients about their levels of salt and fluid consumption in order to provide appropriate advice. In certain cases, it may be beneficial to restrict fluids for patients with dilutional hyponatraemia, reduce intake for patients with high levels of salt and/or fluid consumption, and to continue to review the need to restrict salt or fluid. In addition, healthcare professionals should advise their patients with heart failure to avoid salt substitutes that contain potassium.
