What lifestyle changes can help treat congestive heart failure?
After congestive heart failure is diagnosed, treatment should be started immediately. Lifestyle modification is one of the most important aspects a patient can incorporate to treat congestive heart failure. Some of these lifestyle changes include:
- Fluid regulation
- Weight maintenance
Sodium: Sodium causes an increase in fluid accumulation in the body's tissues. Because the body is often congested with excess fluid, patients become very sensitive to the levels of intake of sodium and water. Restricting salt and fluid intake is often recommended because of the tendency of fluid to accumulate in the lungs and surrounding tissues.
- An a "no added salt" diet can still contain 4 to 6 grams (4000 to 6000 milligrams) of sodium per day.
- In individuals with congestive heart failure, an intake of no more than 2 grams (2000 milligrams) of sodium per day is generally advised.
- Reading food labels and paying close attention to total sodium intake is very important. Severe restriction of alcohol consumption also is advised.
Aerobic exercise, once discouraged for congestive heart failure patients, has been shown to be beneficial in maintaining overall functional capacity, quality of life, and perhaps even improving survival. Each person's body has its own unique ability to compensate for the failing heart. Given the same degree of heart muscle weakness, individuals may display widely varying degrees of limitation of function. Regular exercise, when tailored to the person's tolerance level, appears to provide significant benefits and should be used only when the individual is compensated and stable.
Addressing potentially reversible factors
Depending on the underlying cause of congestive heart failure, potentially reversible factors should be explored. For example:
- In certain persons whose congestive heart failure is caused by inadequate blood flow to the heart muscle, restoration of the blood flow through coronary artery surgery or catheter procedures (angioplasty, intracoronary stenting) may be considered.
- Congestive heart failure that is due to severe disease of the valves may be alleviated by valve surgery in appropriate patients.
- When congestive heart failure is caused by chronic, uncontrolled high blood pressure (hypertension), aggressive blood pressure control will often improve the condition.
- Heart muscle weakness that is due to longstanding, severe alcohol abuse can improve significantly with abstinence from drinking.
- Congestive heart failure that is caused by other disease states may be similarly partially or completely reversible by appropriate measures.
The total amount of fluid a patient consumes must be regulated. Although many people with congestive heart failure take prescription diuretics to aid in the elimination of excess fluid, the action of these medications can be overwhelmed by an excess intake of water and other fluids. The maxim that "drinking eight glasses of water a day is healthy" certainly does not apply to patients with congestive heart failure. Patients with more advanced cases of congestive heart failure are often advised to limit their total daily fluid intake from all sources to 2 quarts.
The above guidelines for sodium and fluid intake may vary depending on the severity of congestive heart failure in any given individual and should be discussed with their physician.
An important tool for monitoring an appropriate fluid balance is the frequently tracking the patient's body weight. An early sign of fluid accumulation is an increase in body weight. This may occur even before shortness of breath or swelling in the legs and other body tissues (edema) is detected. A weight gain of 2 to 3 pounds over 2 to 3 days should prompt a call to the physician, who may order an increase in the dose of diuretics or other methods designed to stop the early stages of fluid accumulation before it becomes more severe.
