How To Treat Hypernatremia Caused By Kidney Failure

2013-04-28 10:30

Hypernatremia is very common among kidney failure patients especially if the patient has diabetes or high blood glucose levels. It is called hypernatremia in clinic when sodium concentration in the blood is more than 150mmol/l.

Sodium plays important role in maintaining fluid balances, regulating blood pressure, supporting the work of nerves and muscle for the body. When there is sodium imbalance in the body, patients will develop a series of symptoms.

In the early stage patients can have frequent thirsty, reduce urine output, weakness, nausea, vomiting, high body temperature, in the end stage it can cause more severe symptoms such as restless,drowsiness, seizure or even coma, etc. In some serious condition it can even cause death, therefore early prevention and effective treatment for hypernatremia is very important for kidney failure patients.

We need first to know why kidney failure cause high sodium levels in the blood. One major reason is the decreased renal excretory ability. Impaired renal functions can not remove excess sodium from the blood especially if patients have too much intake of salt. Besides, loss of large amount of fluid, not drinking enough water, sweating, vomiting, diarrhea or some certain diuretics can all be possible causes.

Hypernatremia is often accompanied by water imbalance, therefore treatment for hypernatremia should aim at restoring the normal balance and order of water and sodium in the body. According to the severity of hypernatremia, different treatment measures will be given. In the early stage when the condition is not very severe, patients can have more fluid intake or have some electrolyte replacement fluids. In the later stage when conditions become serious, intravenous fluid may be required.

For kidney failure patients, a low-salt diet is very important for them whether they have developed hypernatremia. It can not only help prevent and treat hypernatremia but also can help control high blood pressure and relieve fluid retention and swelling.
