Kidneys are an important site of toxin excretion, and their ability to protect against toxins will age.
As we age we are at risk for kidney damage.
If you have kidney function issues you are at risk for many diseases, including problems with fatigue and nutrition.
If you do have kidney damage you are more at risk for infections, as well as other health consequences, and you need to make sure your vaccinations are up to date.
Extent of kidney damage is measured by blood testing, and any degree of kidney damage is measured over a three month period of time. Not just one test.
Most causes of early kidney damage are reversible if you work with your primary care physician.
