A Brief Guide to Kidney Stone Prevention: “Fact versus Fiction”

According to current estimates, kidney stones may develop in an in 10 people during their lifetime. This translates into almost 30 million people who are in the United States.

The prevalence is highest among those aged 30-45 decades. High urinary calcium may function as the cause of kidney stones at upwards of 80 percent of cases. Probably the most prevalent stone composition is calcium oxalate. Once kidney stones develop, patients have a 50%-75% odds of developing another stone.

The yearly price tag of kidney stones from the United States has been 2 billion (treatments, hospitalizations, lost job, etc.) in 1994 and is currently estimated at $5 billion.1

General guidelines for prevention include moderate protein intake, minimal salt ingestion, and drinking enough fluids that are clear to generate 2 liters of urine every day. A low oxalate diet also has proved beneficial for preventing calcium oxalate stones.

Reducing elevated urinary calcium levels helps improve urinary saturation kinetics. Lactic acid stones require dietary manipulation, adequate fluid intake to optimize quantities, and manipulation of urinary pH. Cystine stones, while relatively rare, require their particular preventive measures.

Which fluid to beverage will be controversial. While water may be your mainstay, quite a few articles adapted the benefit of different juices. By way of example, lemon juice increases urinary citrate and could prevent calcium stones. Whether a person uses the recommended half cup of lemon juice daily straight diluted or up, is still really a personal choice. Lemonade is another usually recommended choice.

You’ll find various opinions when it concerns the benefits of orange juice. Additionally too, increases urinary citrate levels, however, there’s a concern it might raise oxalate levels. Apple and lemon juice contain oxalates and have now been associated with a higher risk of calcium oxalate stones.

Likewise, lemon juice was associated with an increased risk of stone formation. Soft-drinks, by using their magnesium content, may possibly cause an increased risk for kidney stones.2,3 The choice of fluid depends upon other variables inside the patient’s urinary chemical composition.

Think about sugar?

Analysis by the Nurses Health Study II has shown that sugar increased kidney stone risk in young women from more than 30 percent. Whether that was a completely independent variable was unclear however, the message is that high sugar whether fructose or alternative sugar, is most probably detrimental from the prevention of further kidney stones.

And the calcium controversy? Calcium supplements, in excess, increase your risk for forming kidney stones. Given each the studies and commentaries, the most simple home message is a diet containing normal amounts of calcium along with salt and animal protein reduction will more than likely protect against stones better compared to the usual minimal calcium regimen.

It’s accepted that the diet too low in calcium intake enables preferential absorption of oxalate from the gut and increase the risk of calcium oxalate stones.

If diet alone isn’t helpful in correcting an abnormal urinary chemical environment, subsequently medications are occasionally offered. These include thiazide diuretics such as high urinary calcium levels, citrate supplementation including non-urinary citrate levels, cystine binding drugs (i.e., penicillamine) to get cystine stone prevention, in addition to new options to the horizon, including oxalate degrading enzymes. However, like most drugs, all these options have unwanted effects. Thiazides, for instance, can worsen glucose tolerance, cause electrolyte imbalance, also aggravate cholesterol levels.

Besides dietary ideas and possible medications, there exists really a more homeopathic approach that centers around nutraceuticals. Is that fact or fiction?

Some can argue fiction, however, also the literature provides supportive evidence. Citrate itself, while available in capsule form, is available in fluids like lemonade. Although the capsule provides a higher potency of citrate, using citrate via fluids is certainly a simplistic yet natural approach. Citrate acts to stabilize the crystal formation rate and will be used to adjust urinary pH at the appropriate clinical setting.

Other Important Tips

Specifically, citrate has been theorized to behave by binding calcium at a soluble complex, hence reducing the amount of calcium available for binding to oxalate.4,5

When 24 hour kidney stone risk profiles have been performed, magnesium levels are an integral indicator regarding the possible stability of their urinary environment.

Ergo the most direct method of raising urinary magnesium levels is by nutritional supplements. Magnesium oxide is often recommended at doses of approximately 400 milligrams every day.

Even though dietary oxalate restriction could be your mainstay recommendation for those who have high urinary oxalate, pyridoxine may be used as a complementary treatment. Caution should be exercised when taking pyridoxine because high doses might cause neurologic issues. Ordinarily, a dose of 50mg can be used.

I think, perhaps one of the most overlooked natural preventatives to get calcium-based kidney stones is phytate, otherwise called ip6 (inositol hexaphosphate).8,9,10 IP 6 was studied as far back as the 1950’s in Harvard at which it had been shown to reduce the frequency of calcium established stones.11 IP 6 acts by preventing crystallization of calcium salts whether the oxalate or phosphate number.12 Studies have shown reduced crystal formation in rats in addition to showing exactly the exact same in humans.12,13 That really is actually a tremendous alternative to using hydrochlorothiazide in patients with hypercalciuria and can be clearly without the possible negative effects.

Therefore what would have been described as a straight forward regular recommendation to prevent bladder stones for nearly all patients? It would be to limit salt, beverage adequate and appropriate fluids, moderate animal protein intake, Reduce sugar intake of forms, ingest adequate amounts of calcium, also ardently consider intake of high fiber plant foods containing phytate.
