Coffee – Renal Failure and Kidney Stone


Coffee may have some effects on renal failure and kidney stones.

Can too much coffee and caffeine damage your kidneys and cause you to have kidney failure?

Some doctors may say that, drinking too much coffee and soda will not cause kidney failure. Renal failure occurs for reasons such as genetic factors, infections, obstructions and trauma to the kidneys.

Well, the logic of this kind of advice is something like talking about smoke: lung cancer is caused by genetic factors or infections, not by smoking, because a lot of smoking people never have lung cancer.coffee-renal

The point is that, for those people who were born with strong kidneys, they are likely free from renal failure, even drinking a lot of coffee or soda, but for those who have weak kidneys, coffee will not help them, as coffee is loaded with potassium which is not allowed in renal failure, as potassium rises quickly in the blood.

But kidney failure is different from another kidney disease – kidney stones.

Kidney failure is a medical condition in which the kidneys fail to adequately filter toxins and waste products from the blood, concentrating the waste in the form of urine. The kidneys cannot remove metabolic waste matter, toxic material and excess of water.

Kidney stones are solid concretions or calculi formed in the kidneys from dissolved urinary minerals. Research suggests that cadmium is a heavy metal that is increased in stone-formers.

While drinking too much water may cause loss of kidney function, leading to kidney failure, a high fluid intake is an effective treatment for kidney stones. Long-term coffee drinking or caffeine has been shown to result in increased calcium loss. In other words, coffee consumption lowers the risk of developing a kidney stone.

So as we can see that, coffee is not help for treatment of kidney failure, but could be help for treatment of kidney stone.
