Conclusion: All HF patients are advised to refrain from consuming excessive amounts of fluid, according to the 2021 ESC HF recommendations. An average person’s daily fluid consumption typically ranges from 1.5 to 2.5 L, or 15–30 mL/kg. A restricted fluid strategy usually involves an intake of less than 1–1.5 L/day, whereas a more liberal approach is thought to comprise an intake of more than 2.5–3.0 L/day.
