Low Sodium Diet


Low Sodium Diet

Low sodium diets tend to be prescribed by healthcare specialists to help improve or control specific medical conditions. Sodium is an essential mineral integral to many functions in the body. 

 High-salt diet


What is a low sodium diet?

Sodium is found naturally in a lot of foods and is the main component of table salt. A diet low in sodium is frequently recommended to people whose health conditions can be aggravated through high sodium intake:

  • Hypertension
  • Heart failure
  • Chronic kidney disease 

Healthy kidneys have many functions, including regulating sodium levels. Therefore, when your health condition affects renal function, doctors recommend keeping sodium intake under 2 to 3 grams per day (or 3,000mg sodium).  


What can a low sodium diet achieve?

Individuals with compromised kidney function find that sodium restriction can help reduce the risk of pressure buildup in the blood and further kidney damage. Indeed, when the kidney can't eliminate waste and excess fluid effectively, high sodium intake can lead to fluid buildup and edema, as well as increased blood pressure.

 Patients who already have hypertension are at risk of heart disease and stroke. Reducing sodium intake can be instrumental in controlling blood pressure. 

 If you already have a heart condition, such as heart failure, kidney function is likely to decline, which can lead to swelling through the excess fluid. While swelling is commonly noticed in hands, arms, feet, ankles, and legs, it could develop anywhere in the body, leading to risks of pulmonary edema.
