The sodium restriction recommended for adults with chronic kidney disease is typically around 2 grams per day. This recommendation is based on the need to help manage blood pressure and reduce fluid retention, which are common concerns for patients with kidney disease.

Excess sodium can lead to hypertension, exacerbating kidney damage and increasing the risk of cardiovascular complications. By limiting sodium intake, patients can better control their blood pressure, minimize edema, and decrease the workload on the kidneys. This restriction also helps manage other related issues, such as heart disease, that commonly complicate chronic kidney disease.

While higher or lower sodium limitations can exist based on individual patient needs and phases of the disease, the general guideline for sodium intake in this population is set around 2 grams daily for most adults. This helps to achieve optimal management of the condition while encouraging healthier dietary practices.
