Does Drinking Water Help the Kidneys?

Water is essential for our overall health and wellbeing. Our bodies are made up of about 60% water, and it plays a crucial role in keeping our bodies functioning properly. One of the most significant benefits of drinking water is its impact on our kidney health. Our kidneys are responsible for filtering waste and toxins from the blood and regulating the body’s fluid balance. But can simply drinking water help our kidneys function better? Let’s dive into the details to find out.

The Importance of Hydration for Kidneys

Our kidneys are responsible for filtering around 200 quarts of blood every day and producing about 2 quarts of urine, which helps get rid of toxins and waste products from the body. To do this efficiently, our kidneys need an adequate amount of water to function correctly. Dehydration, where the body does not have enough fluid, can lead to many problems, including kidney stones and urinary tract infections. Drinking enough water ensures our kidneys can properly filter and eliminate waste from the body, thus helping to prevent these issues.

Less Water Intake Can Lead to Kidney Stones

Kidney stones are hard deposits of minerals and salts that form inside the kidneys. They can be caused by many factors, including genetics, diet, and dehydration. When we don’t drink enough water, the urine becomes highly concentrated, making it more likely for minerals and salts to crystalize and form into stones. Drinking more water helps dilute the urine, preventing the formation of kidney stones. Moreover, staying hydrated can also help flush out small stones before they grow in size and cause more significant problems.

Water Helps with Urinary Tract Infections (UTIs)

Urinary tract infections are one of the most common bacterial infections, and they typically occur when bacteria enter the urinary tract through the urethra and multiply in the bladder. Drinking plenty of water helps to flush out harmful bacteria that can cause UTIs, thus reducing the chances of infection. Staying hydrated can also help to prevent future UTIs by keeping the urinary tract clean and free from bacteria.

The Impact of Dehydration on Kidney Function

The kidneys require a certain amount of water to function correctly. When we are dehydrated, our kidneys have to work harder to filter out waste products, making them prone to damage. Long-term dehydration can lead to chronic kidney disease, a condition where the kidneys gradually lose function over time. This can result in the buildup of waste and fluid in the body, leading to other health issues.

How Much Water Should You Be Drinking?

The recommended daily intake of water for a healthy adult is about 2 liters, or 8 glasses. This can vary depending on factors such as activity level, climate, and health conditions. However, it’s essential to note that not all fluids are created equal. Some beverages such as alcohol and caffeinated drinks can actually have a diuretic effect, leading to increased urination and dehydration. Therefore, water is still the best and most effective way to stay hydrated and maintain kidney health.


It’s clear that staying hydrated is crucial for maintaining good kidney health. Drinking enough water helps our kidneys function properly and can prevent many issues such as kidney stones, UTIs, and chronic kidney disease. So, make sure to keep a water bottle handy and stay hydrated throughout the day. Your kidneys will thank you!
