The Truth: The Link Between Water and Kidney Stones


Does Drinking a Lot of Water Help Pass Kidney Stones?

Kidney stones are small, hard deposits that form in the kidneys. They are made up of minerals and salts that can cause severe pain and discomfort when passing through the urinary tract. While there are various treatment options available for kidney stones, one of the most commonly recommended self-care methods is increasing water intake. But does drinking a lot of water really help pass kidney stones? In this article, we will explore the relationship between water intake and kidney stones.

Understanding the Role of Water in Kidney Stone Formation

Water is essential for our body as it helps in flushing out toxins and waste products through urine. The kidneys play a crucial role in this process by filtering the blood and producing urine. When there is not enough water in the body, the urine becomes concentrated and the minerals and salts can form crystals. Over time, these crystals can grow in size and develop into kidney stones.

The Benefits of Drinking Water for Kidney Stones

Drinking an adequate amount of water helps dilute the urine and prevents the formation of crystals. This means that if you are someone who is prone to kidney stones, increasing your water intake can help reduce your chances of developing them. Additionally, drinking water can also help in flushing out small stones and reducing the risk of them becoming larger and more difficult to pass.

Moreover, staying hydrated can also help with the pain associated with passing kidney stones. When the urine is concentrated, it can irritate the lining of the urinary tract, leading to discomfort and pain. Drinking water helps in diluting the urine, making it less irritating and easier to pass.

How Much Water is Enough?

The amount of water one should drink to prevent kidney stones can vary depending on factors such as age, weight, and overall health. However, a good rule of thumb is to aim for at least eight glasses of water (around 2 liters) per day. This amount can increase if you live in a hot climate, exercise frequently, or have a history of kidney stones.

It is essential to note that simply increasing water intake may not be enough to prevent or treat kidney stones. It is also crucial to maintain a balanced diet and limit the consumption of foods high in oxalates, such as spinach, chocolate, and nuts, as they can contribute to the formation of kidney stones.

When to Seek Medical Help

While drinking water can be beneficial for kidney stones, it is not a magic solution. In some cases, medical intervention may be necessary. You should consult a doctor if you experience severe pain in your back or side, blood in urine, persistent nausea or vomiting, or difficulty passing urine. These could be signs of a larger or obstructive stone that may require surgery or other medical treatments.

The Bottom Line

Drinking a lot of water is essential for overall health and can play a role in preventing and helping to pass kidney stones. However, it is not a guaranteed solution, and it is always best to consult with a doctor for proper diagnosis and treatment. Remember to maintain a balanced diet, limit foods high in oxalates, and stay hydrated to keep kidney stones at bay.
