Can Beer Help Pass Kidney Stones? Here’s What a Urologist Says

The rising incidence of kidney stones — especially among young adults — has sparked growing concern among health experts.

While small stones can sometimes pass naturally through urine, doctors emphasize the importance of staying well-hydrated to ease the process. A popular belief suggests that drinking beer can help flush out kidney stones, but is there any scientific truth to it? According to Dr. Amrendra Pathak, Vice Chairman of the Urology Department at Sir Ganga Ram Hospital, New Delhi, the answer is no.

Dr. Pathak explained that kidney stones form when minerals such as calcium, oxalate, and uric acid accumulate in the kidneys and crystallize. These crystals can grow into larger stones, potentially blocking the urinary tract and causing severe pain, burning, or even blood in the urine.

While stones smaller than 5mm may sometimes pass through urine, larger ones often require medical or surgical intervention. The most effective way to help the body eliminate stones naturally, he said, is drinking plenty of water, which dilutes urine and promotes smoother passage.

On the beer myth, Dr. Pathak clarified that beer does not contain any compounds that help dissolve or expel kidney stones. Though beer acts as a diuretic — increasing urine output — this does not ensure that the stones will pass. “The same diuretic effect can be achieved through lemon water or plain water, without the side effects of alcohol,” he noted.

He also cautioned that beer consumption can do more harm than good. Alcohol may increase uric acid levels, cause dehydration, and lead to kidney swelling or liver complications. “Patients with kidney stones should avoid beer altogether. It doesn’t help remove stones — it can actually make things worse,” Dr. Pathak added.

In short, beer is not a remedy for kidney stones. The safest and most effective approach remains adequate hydration, timely medical evaluation, and a healthy diet to prevent recurrence.
