Nephropathy (Kidney Disease)
Our kidneys keep us healthy by filtering out waste and things
that might harm us but keep in things we need. High blood
sugar and high blood pressure will damage the capillaries. The
damage that diabetes causes to the capillaries can damage the
kidneys.
How does diabetes affect my kidneys?
The kidneys act to filter the blood. Waste products that are in the
blood are removed and pass from the body in the urine. The clean blood
returns to the body.
Over time the damage from diabetes and high blood sugar will cause the
kidneys to not filter the blood so good. The waste products may then
build up in the blood and some of the good products that the kidneys try's
to hold back may start to leak out. This is called nephropathy.
How can I know if my kidneys are affected?
In the early stages you won't feel anything. The good part of the
kidneys is able to make up for the damaged part. As the damage
increases the kidneys start to fail.
There is a urine test and a blood test that can show signs of early
kidney damage. These tests should be done at least once a year.
Kidney damage can increase blood pressure, so worsening blood pressure
might be a sign of kidney problems. Some other signs include itchy
skin, extreme tiredness, nausea and swelling legs and ankles. These
signs do not always mean kidney problems. but if you notice any of them you
should discuss it with your doctor.
How are kidney problems treated?
In the early stages medications will help. Sometimes a diuretic or
water pill will help. Also some blood pressure medicines will help.
If the damage gets worse then dialysis might be needed.
How can kidney disease be prevented?
Diabetic kidney disease can be prevented or at least delayed if you keep
your blood sugar in normal range. Keeping blood pressure below 130/80
will help too, because higher blood pressure also causes damage.
Medications called ACE Inhibitors will protect the kidney some from
diabetes.
