Effects of Dehydration on GFRDehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions. This article is about the effects of dehydration on Glomerular Filtration Rate (GFR).

How does dehydration affect GFR?

When dehydration occur, your body lacks of water, causing reduced blood volume in the kidney. Specifically, GFR estimates how much blood passes through the glomeruli each minute. Therefore, when the blood that decreases in the glomeruli, the glomerular filtration rate declines.

What is the normal range of GFR?

A normal GFR or Glomerular Filtration Rate, is similar in both men and women. For adults it is between 100-130 ml/min/1.73m2. For children a GFR at 110 ml/min/1.73m2 is normal.

What will happen if GFR declines due to dehydration?

In mild cases, people with dehydration usually experience symptoms like dry mouth, thirst, dizziness, and rapid heart rate. When it becomes serious, people may have shortness of breath, confusion, leg cramps or even Acute Kidney Failure (AFR).

Besides, due to decreased GFR, patients may also have decreased urine output or even no urine.

When should you be concerned?

Since GFR always indicate kidney damage, you should also take a urine or blood test to check how well your kidneys are working. Normally, when GFR is below 60ml/min, it should draw your concern.

How to increase GFR?
