Can Alcohol Cause Kidney Stones? The Surprising Link

It’s a beautiful weekend afternoon. You’re at a lively barbecue, the grill is sizzling, laughter fills the air, and a cooler full of cold drinks is calling your name. You grab a beer, then another, and before you know it, you’ve had quite a few.

But in the middle of all the fun, have you ever stopped to think about the health effects of drinking alcohol? We’re not just talking about the next-day hangover—there’s a less-discussed risk that can sneak up on you: kidney stones. So, can alcohol cause kidney stones? Let’s take a closer look at the connection.

What Are Kidney Stones?

Kidney stones may be small, but they can cause intense pain. These hard, pebble-like deposits form inside your kidneys when substances like calcium, oxalate, and uric acid build up and crystallize. Several factors can increase your risk of developing them, including:

• Family history
• Chronic dehydration
• A diet high in protein and salt
• Excessive alcohol use

While many kidney stones pass naturally through urine, they can still cause significant discomfort. In some cases, they can lead to complications like urinary tract infections or kidney damage if not treated.

How Does Alcohol Lead to Kidney Stones?

Alcohol can raise your risk of kidney stones in several ways. One of the main reasons is that alcohol acts as a diuretic—it makes you urinate more. While that might sound helpful, it can actually lead to dehydration. When you’re dehydrated, your urine becomes more concentrated, making it easier for stones to form.

Some alcoholic drinks, like beer, are high in purines. These compounds break down into uric acid, which can contribute to certain types of kidney stones. Heavy drinking over time can also lead to high blood pressure and liver disease, both of which are linked to kidney problems and a higher risk of stones.

Treating Kidney Stones

If you develop a kidney stone, there are several treatment options depending on its size and your symptoms. Small stones often pass on their own with plenty of water and pain relief. For larger stones, treatments may include:

• Sound wave therapy (lithotripsy) to break the stone into smaller pieces
• Surgery in more serious cases

Preventing Kidney Stones

Prevention is always better than treatment. To lower your risk of kidney stones:

• Drink alcohol in moderation and stay mindful of the risks
• Stay hydrated—have a glass of water with each alcoholic drink
• Eat a balanced diet with enough calcium and less salt
• Limit foods high in oxalates, like spinach and almonds
• Stay active with regular exercise

Final Thoughts

Enjoying life includes taking care of your body. While it’s okay to have a drink now and then, excessive alcohol use can increase your risk of health issues like kidney stones. By drinking mindfully, staying hydrated, and maintaining a healthy lifestyle, you can reduce your risk and continue to enjoy social occasions without worry. Your kidneys—and your overall health—will thank you.
