Imagine your body is like the house you live
in. Every day, your family creates rubbish. The rubbish builds up until it is
put out for the weekly garbage collection.
Now, say you put three bags of garbage out,
but because one of the collectors was away sick, only two bags are collected.
You take the leftover bag inside to be put out again next week. The following
week you put on another three bags, plus the leftover bag from last week. But
again, only two bags are collected. Imagine this cycle is repeated over the
following weeks.
This is a simple description of what happens
to your body when your kidneys (肾脏) don't work efficiently.
Your body is not thoroughly emptied of waste products. Other areas of the body
such as blood pressure and red blood cell production are affected and the insidious process that may lead
to kidney failure begins.
It's not uncommon for people to lose up to
90% of their kidney function before developing any symptoms. There may be no
warning signs. This makes early detection (诊查)difficult.
Kidney's main job is to remove toxins (毒素) and unwanted water from our blood. Every day our kidneys clean
an average of 200 litres of blood.
Kidney failure may be a gradual and silent process, going unnoticed because
there is no obvious pain.
Research shows that more than 35% of the
patients requiring dialysis (透析) do not see a kidney
specialist before they have to do so. Some risk factors for kidney disease such
as age and genetic make-up are out of our control; however, some changes in
lifestyle may help prevent kidney damage. Two major risk factors for kidney
disease, diabetes (糖尿病) and high blood pressure,
have been on the rise over the last few decades. Both conditions are chiefly
affected by being overweight and not getting enough exercises, which are the
potential (潜在的) risk factors for the
kidney disease.
