Does Water Retention Cause Weight Gain?

There are many possible causes of weight gain. Typically, it is because you are eating too much calories regularly and not performing physical activities regularly. However, there are many other reasons why a person gains weight. It may be a side effect of certain medication but it may also be due to very low-calorie intake or because of too much stress. One of the most common causes of quick weight gain is water retention. Let’s take a closer look at this problem and how to solve it.

What Is Fluid Retention?

Does Water Retention Cause Weight Gain?

Did you know that you can easily retain more than 5 pounds of water at the end of the day? This may be due to the foods you consumed, your activity levels for the day or your hydration levels. If your diet is high in fat, sodium and other preservatives, you tend to retain more fluids in the body which causes instant weight gain. High-sodium food causes an imbalance in the sodium and potassium levels in the body resulting in edema.


Water retention can also be due to PMS. The fluctuation of blood sugar levels during this time may cause retention of extra fluids in the body. Some researchers suggest that water weight from PMS is also because of sodium. Around one week before a woman’s period, the blood breaks down progesterone which causes the retention of water and sodium by the kidneys.

Reducing Water Retention

Regardless of the cause of water retention, there are several things you can do to prevent it. Although this may sound counterproductive, drinking plenty of water can help prevent the retention of fluids. When the body is dehydrated, it tends to hold on to water which causes edema. Also, drinking plenty of water can help flush out excess sodium and other substances that cause fluid retention.

Change Your Diet

If you consume a lot of unprocessed foods which are high in sodium, salt and other preservatives, changing your diet can significantly reduce water retention. The basic rule is to consume a diet high in unprocessed foods like fruits and vegetables. Also, watch out for carbonated colas and other beverages that contain a high amount of sodium.

Foods for Reducing Water Weight Gain

You can also consume certain foods that are proven to work against water retention. Among these foods are apricots, avocados and bananas. You can also consume coffee which is high in caffeine. Caffeine is a diuretic which gets rid of excess fluids in the body. There are also supplements for water retention available. These products are usually made from herbs and other natural diuretics that address fluid retention. Make sure to perform extensive research to ensure that the product is not just effective but also safe. If nothing works in treating the problem, you need to consult your doctor because an underlying condition may be causing the fluid retention.
