kidney pain in a skier
Kidney pain in a skier, whilst it’s very rare it can be
related to body dehydration. Classically though,
it is usually encountered in individuals with
kidney stones, so again not likely encountered on your off-piste snow
expedition, unless you have a pre-existing kidney problem.
Kidney pain or renal colic involves the lower back region radiating towards
the bladder.This is the area approximately where the rib cage finishes right
down to the the pelvis region.
This type of pain can involve any segment of that region.In its acute form,
it is a sharp stabbing pain which has been compared to the sharpest pain
sensation known to man.
For most of us any sensation experienced in the above regions may be due
to muscular strain ,or local soft tissue injury.
Short term remedy is use of painkillers or analgesics.
On many occasions it is easy to ski in excess of half a day without
fluid replenishment. In retrospect I would recommend fluid
replenishment at least when going beyond the boundries.
Under supervision, on groomed runs, you have less of a worry,as
you are close to civilization.
If kidney pain is present ,this is indicative of either loss of the ability
of kidney to excrete wastes,or concentrate urine,or conserve electrolytes
or generally maintain fluid balance.
Symptoms to look out for when dehydrated and kidneys may ,but are not
necessarily compromised are:
- postural hypotension
( feeling gitty and dizzy upon standing up from a lying down position,is usually an idication
of more serious kidney involvement).
- decreased urine production < 400ml/day/in adults.
* dehydrated lost 2% blood volume
If you are of reasonable fitness level,and consider
yourself quite athletic ,your symptoms may include reduction of optimal performance, flushing, racey heart rate,increased body temperature,rapid and progressive onset of fatigue.
* dehydrated lost 5-10% blood volume
With increasing loss of blood volume your heart rate increases
accompanied by increased respiration.Fatigue is slowly getting the
upper hand, and malaise is becoming prominent.
You may start to feel sleepy ,nauseous ,tingly in hands and feet.The vision will start
to become blurry. Muscles become spastic and don’t always obey
your commands .
Simple task of passing urine will become painful.
Early stages of delirium begin to manifest themselves.
* dehydrated lost 10-15% blood volume
This loss of fluid is boardering on being fatal.Your simple
kidney pain is now a sign of kidney failure.
Assuming average blood volume is 4.5litres,you would need to lose
between 450-770ml of fluid to arrive at this state.
To keep up with
replenishing fluid loss via sweating and urine output you need
to drink a minimum of 3litres/day.When you exercise ,this number
Replenish the body with not just water but electrolytes.
A modified rule of thumb is 8 teaspoons of sugar with 1 teaspoon
of table salt mixed in 1 litre of water.
Surfing down the slopes takes some fluid out of you,so for us skiers hydration
is on top of this agenda.Enjoy the slopes.
