Can Dehydration Cause High Protein in Urine?

Protein does not typically appear in the urine in detectable quantities, according to the Edinburgh Renal Unit. Proteinuria, which is protein excretion of 150 milligrams or higher per day, may indicate kidney damage, but it can also be the result of more benign factors, including dehydration.

Protein and Your Kidneys

When blood circulates through healthy kidneys, a system of tubules, called glomeruli, filter out waste products and leave behind substances your body needs, including proteins. When the kidneys are damaged, proteins may reach detectable levels in the urine.

Staying Hydrated

Protein excretion levels vary from person to person, and may rise above 150 milligrams per day if you fail to drink enough water. Drink small quantities of water every hour and increase your fluid intake to compensate for hot weather or strenuous exercise. Contact your physician if you notice any of the signs of proteinuria, including foamy urine or swelling in your face, hands, feet or stomach.
