Dehydration can Lead to Acute Renal Failure

Dehydration is one of important causes of Acute Renal Failure. Dehydration is a manifestation of metabolic disorder due to diseases and excessive consumption of fluid, but the body can not get enough fluid supply timely. In severe case, it can cause collapse and even threaten the patients' life. It includes hypotonic dehydration, hypertonic dehydration and isotonic dehydration.
The kidneys filter wastes from blood to maintain normal physiological activity. However, dehydration can cause reduced blood volume. As a result, the body can't adequately to circulate blood which carries wastes products to kidneys, so those wastes products accumulate in body. That is how Acute Renal Failure occurs in dehydration.
If dehydration occurs, you may experience dry mouth, thirst, dizziness and rapid heart beat, shortness of breath, confusion and swelling in feet and ankles.
Generally, Acute Renal Failure can be reversed and rarely develops into Chronic Renal Failure.
As Acute Renal Failure is caused by reduced blood volume, the primary treatment should be restoring the blood circulation. The doctors will be performed with intravenous fluid infusion to increase the circulatory blood volume.
In severe cases, dialysis will be required to treat Acute Renal Failure. Different from Chronic Renal Failure, the kidneys do not have damage injury. If the metabolic wastes and extra fluid, etc are filtered out of body by dialysis, your renal function will be reversed and dialysis will not be needed.
If you can take preventive measures to avoid dehydration, the incidence of Acute Renal Failure will reduced drastically.
If you have some diseases which may cause dehydration, you should supply water timely. Also, if you have heavy sweat and take intense exercise or other activities which can cause sweating, you should have enough fluid containing proper amount of sugar and electrolyte.
