Dehydration
Check for Dehydration
Dehydration can increase blood pressure and decrease kidney functioning.
How to tell if one is dehydrated?
Some have asked how to tell if one is drinking sufficient water? Dehydration will quickly shut down kidney functioning. If one can drink 3 liters of water per day this will shut down vasopressin. Shutting down vasopressin will diminish cyst growth. Dehydration can quickly hasten end stage renal disease. Dehydration shuts down kidney functioning in normal individuals without any type of kidney disease.To check that you are not becoming dehydrated try the pinch test for skin turgor. To determine skin turgor, grasp the skin on the back of the hand; pinch the skin between two fingers so that it looks like a tent. The skin is held for a few seconds then released. Skin with normal turgor snaps rapidly back to position. Skin with decreased turgor remains elevated or returns slowly to its normal position. This has been referred to as stand up skin, a sign that one needs to increase their water intake; a sign that one is dehydrated.
Effect of Ultra Sport on Renal Functioning
These results suggest that reduced renal perfusion is the mechanism responsible for the slight impairment of renal function following exhaustive marathon cycling. This comes about even from well-hydrated athletes. Blood and urine specimens were taken the day before, immediately after and one day after competition. There was an 18% decline in creatinine clearance though these effects lasted only for 24 hours despite a stable fluid balance during the race and an expanding plasma volume (PV) in the recovery period.
