Q&A: Does Water Flush Out Sodium Effectively? (Water & Health)

Do you feel like you’re probably getting too much sodium in your regular diet?

Are you concerned with looking for ways to reduce or remove the sodium that’s in your body?

Does water flush out sodium?

In this article, we’ll give you a list of facts you need to know about how sodium interacts with water and what, if anything, drinking water can do to improve the amount of sodium present in your body.

It’s common knowledge that it’s not always a good idea to have too much sodium, even though sodium is an electrolyte that the human body needs to function. It’s all about finding the right balance in order to get the perfect amount to keep you going strong without making you sick, bloated, or overweight.

What constitutes too much sodium, anyway? How can you know you’re eating too much of it in a day? Speaking with your doctor or your dietitian can be a great way to get a personalized number for the amount of sodium you need every day. However, remember that you should not be eating so much sodium that it makes you gain or retain weight (unless your doctor tells you otherwise).

Having too much sodium in a short-term meal is not ideal, but it’s less of a problem than having too much sodium long-term over weeks or months. Either way, it’s a good idea to have a solid understanding of how water interacts with this sodium and whether or not it can help or hinder your desire to reduce the sodium in your body.

Check out the information we have listed below to help you learn more about the way sodium and water work together—and sometimes work against each other—when it comes to the human body.

Water and Sodium

In this section, we’ll give you some information to help you figure out just how water works in relation to sodium in your body. There are a few important facts you should keep in mind when you’re working on figuring this out. Bear in mind, too, that everyone’s body is different and that you may need to speak to your dietitian or health care provider in order to get some more specialized and personalized information about this matter. However, you should be able to get yourself started in the right direction by paying attention to the information we have put together for you below. Keep the following facts in mind:

  • You feel bloated after eating a salty meal because the sodium in the food you eat retains the water already in your body. If you’re eating and drinking fluids at the same time—like most people do—the water doesn’t have anywhere to go because of the sodium in your high-sodium meal. This essentially makes you bloat up and can cause pain or even heartburn.
  • Because of this, drinking more water can help flush out short-term sodium buildup related to meals. The more water you drink, the more water will be present and able to flush out the fluids that are being retained by the sodium in your food. When dealing with short-term sodium intake, drinking plenty of water is definitely a helpful method of keeping you from getting bloated or holding onto too much sodium.
  • If you have a long-term high-sodium diet, however, drinking water isn’t going to help. Even if you drank more than the recommended amount of water every day while eating your high-sodium diet in the long term, you would not be able to get rid of all that buildup. It would simply stick around, making you retain water at the same time, and it would make you gain weight as well. While this is basically “water weight,” it’s still going to add to your overall body weight as well as the way you fit into your clothing, and it’s not ideal.
  • You may get high blood pressure form a long-term high-sodium diet. It’s no secret that high-sodium diets over a very long period of time can contribute to high blood pressure. Even some people who are sensitive to sodium may experience a brief increase in blood pressure simply after eating a meal or a snack that’s higher in sodium, but this should go back to normal after your body digests the food. However, in the long term, your body doesn’t have time to get back to normal before it’s being fed more sodium. Drinking too much water and causing yourself to bloat up can contribute to high blood pressure from this, too.
  • Drinking water can actually cause long-term sodium to build up and stay there. Now that you’ve seen that drinking water in the long term isn’t a solution for a high-sodium diet, you may be wondering if it can actually hurt you. And the answer is yes, it’s possible that drinking too much water when you’re also eating too much sodium can make matters worse. Simply put, you’re giving your body even more water you can retain, and this is only going to contribute to the weight you put on or keep on. This is why it’s crucial to cut back on foods that are high in sodium rather than expecting water to solve the problem for you.


There’s so much to keep in mind when you’re trying to learn how to handle sodium and water both that it may seem a little overwhelming. After all, it can be tough to keep track of everything you’re supposed to eat or avoid when you’re planning your daily diet and water. However, it’s never too early or too late to start paying attention to your sodium intake, and you may be able to prevent or seriously improve your risk for health concerns like diabetes or obesity by paying attention to the sodium you’re putting in your body on a regular basis.

how to counteract sodium intake

But there has to be more you can do than just drinking the right amount of water depending on your sodium. Is there a better solution? Limiting sodium intake may be better—and it’s sure to work more efficiently in the long run. By cutting back on the amount of sodium you eat every day as well as over the course of a week or month, you can give your body a better opportunity to lose weight, get in shape, and stay healthy. Just don’t neglect to drink plenty of water regularly at the same time as you’re cutting back on your sodium. Doing both of these things together is a sure way to get yourself feeling better and looking great, too.
