Heart Failure Treatment: Details on Liquid Limitation, Supporting Evidence, and Practical Advice
In the management of heart failure, understanding one's fluid intake is crucial. This article aims to provide insight into the recommended fluid intake for heart failure patients, the challenges of fluid restriction, and the importance of individualised clinical management.
For those restricting fluid, the standard recommended intake is 1.5 to 2 liters per day. However, for stable chronic heart failure patients, routine fluid restriction may not be universally necessary, as recent research suggests that it does not improve health outcomes such as hospitalization, mortality, or medication use [3][5].
On the other hand, patients with advanced heart failure and fluid overload are often advised to restrict fluids to 1.5–2 liters daily to help manage volume status [1]. This restriction aims to reduce fluid accumulation that worsens symptoms.
Clinicians should be cautious about dehydration, which can stress the heart by increasing heart rate and blood viscosity, potentially worsening cardiovascular health. Maintaining adequate hydration is important, especially to prevent dehydration-related complications [4].
If a person finds it difficult to stick to a restricted fluid intake, they should ask a doctor for advice. Some tips for restricting fluid intake include using small glasses, limiting salt intake, sucking on hard candy, frozen fruit, or ice cubes, chewing gum, sipping rather than gulping, spacing out fluid intake, controlling sugar intake, measuring out daily fluid intake, making a note of fluid intake, and using a refreshing mouthwash when the mouth feels dry.
It's important to note that heart failure can lead to complications such as pulmonary hypertension and other heart conditions. If a person with heart failure experiences symptoms such as confusion, fainting, lack of urination, rapid heartbeat, rapid breathing, shock, frequent dry, hacking cough, shortness of breath while resting, increased swelling or discomfort in the lower body, sudden weight gain of more than 2-3 pounds, new or worsening dizziness, sadness, depression, or confusion, loss of appetite, increased trouble sleeping, inability to lie flat, they should receive immediate medical care.
The current scientific evidence suggests that restricting sodium intake may benefit people at risk of heart failure or those with asymptomatic heart failure, but it may adversely affect people currently experiencing heart failure symptoms. Temporary fluid restriction can be helpful for certain people with heart failure, and a healthcare professional may also prescribe diuretics and sodium restrictions to treat heart failure.
Approximately 6.5 million adults in the United States have heart failure. It's essential to remember that everyone's situation is unique, and clinical fluid management should be individualized based on the patient’s volume status and symptoms.
In summary, stable chronic heart failure patients generally do not benefit from routine fluid restriction and can regulate their own intake. Patients with advanced heart failure and fluid overload are often advised to restrict fluids to 1.5–2 liters daily. Avoid dehydration, as it places additional strain on the heart. Clinical fluid management should be individualized based on the patient’s volume status and symptoms. If a person experiences symptoms or struggles with fluid restriction, they should consult a healthcare professional.
