There are several unique connections between kidney stones and beer. Drinking beer in moderation can be an effective means of preventing and treating kidney stones. While studies have proven the benefits of beer, they have also found a connection between chronic kidney stones and drinking beer. That is, too much beer drinking can actually make the condition worse.
Kidney stones are caused by the development of calcium deposits in urine. When these deposits mix with salt and other substances, stones develop. When the stones become too large, they can be incredibly painfully as they are passed through the system; in some cases, the condition might require medical treatment. A study from Finland found that drinking one beer a day, especially a stout or porter beer, can prevent these calcium deposits from developing. For those who are prone to developing kidney stones, a daily glass of beer may reduce the chances of the stones developing by up to 40%.
While stouts and porters are especially useful in preventing kidney stones due to their high amount of hops, studies have found that any type of beer can help to treat kidney stones. This connection between kidney stones and beer is twofold. First, beer increases the amount of urine that the body produces, which flushes calcium from the body before it can accumulate with existing kidney stones. This can prevent the stones from becoming any larger, making them easier and less painful to pass.
Secondly, beer in moderation can also dilate the urinary tract. This gives existing kidney stones more room to pass through; this can not only help stones leave the body faster, but also decreases the amount of pain experienced while they are leaving the body. For those who do not drink beer, cranberry juice has a similar effect.
There is also a negative correlation between kidney stones and drinking beer. When consumed in large quantities, this beverage increases acid in urine. When heavy beer drinking continues for long periods, the acid in the urine can become so high that it can cause kidney stones to form. This occurs despite the fact that moderate beer drinking actually discourages kidney stone development. This relationship between kidney stones and beer is why those suffering from alcoholism are often plagued with chronic stones.
While many doctors suggest a daily beer for patients prone to or experiencing kidney stones, it is important to stick to just one a day. For those with a history of developing kidney stones, heavy drinking or binge drinking can put them at risk for severe kidney stones that may require medical intervention. The mix of kidney stones and beer can have both positive and negative results; therefore, moderation is key.
