Is weight loss beneficial for patients with heart failure?

In general, whether weight loss is beneficial for patients with heart failure depends on the underlying cause of the weight reduction. If the weight loss results from increased physical activity, it is usually a positive sign, indicating that the patient's condition is improving. However, if weight loss in heart failure patients is accompanied by symptoms such as poor appetite, nausea, and vomiting, it typically indicates a more severe stage of the disease.

If weight loss occurs due to positive lifestyle adjustments—such as controlled, balanced dieting and moderate increase in physical activity—leading to elimination of excess fluid and reduced body fat, while cardiac function remains relatively stable, then this type of weight loss may be beneficial, reflecting effective self-management by the patient.

Conversely, if weight loss occurs without intentional effort and is associated with明显 decreased appetite, fatigue, and deteriorating mental status, it may signal a new or worsening medical condition. For example, worsening heart failure could lead to increased gastrointestinal congestion, impairing nutrient absorption, or there may be other underlying wasting diseases such as malignancies. Weight loss under these circumstances is concerning and often suggests a decline in the patient’s overall health.

It is recommended to maintain a low-salt diet, reduce fluid intake, avoid prolonged standing or sitting, consume nutrient-rich foods, and engage in moderate physical activity regularly.
