Water Retention and Bloating Causes

When bloating results in increased stomach girth, it's called distention. So, when your stomach starts to blow up to twice its side, you're probably experiencing distention from bloating. There's no need to be alarmed though, the bloating can and will go away.

Common causes for bloating include intestinal inflammation and gastric issues similar to irritable bowel syndrome (IBS) and gastroesophageal reflux disease (GERD). Another reason could be out-of-balance bacterial growth in the bowels. Outside of stomach issues, eating too fast, swallowing air while eating or gaining weight can cause bloating.

Water retention is also a significant cause of bloating. According to a May 2017 study in the Journal of Clinical Investigation, salt is a major player in water retention. Too much salt will cause the body to start storing excess amounts of water. Without a form of release, that water builds up, creating distention in your stomach.

Foods That Cause Bloating

Before you find out which foods are good for reducing water retention, you need to understand which foods cause bloating in the first place. Confusingly, some foods that cause bloating also reduce water retention. That's because water bloating and gastric bloating have different causes. So, it's best to avoid foods that cause gastric bloating, even if they have also been found to reduce water retention.


About IBS lists several foods as bloating irritants:

  • High-fiber foods
  • Dairy products, particularly for people with lactose sensitivity
  • Beans
  • Legumes
  • Cauliflower
  • Broccoli
  • Onions

While this list is particular to those with gastric issues, the foods listed are general irritants as well. So even if you don't have IBS, be wary of these foods. One of the easiest ways to find out if it's an irritant for you is to monitor your body's response for 24-hours after trying that food item.


Potassium Reduces Water Retention

The American population tends to eat too much sodium and not consume enough potassium, according to the Centers for Disease Control and Prevention. This can lead to several serious health issues, such as high blood pressure and cardiovascular failures. Increasing potassium in your diet helps to balance your body's sodium. If you're experiencing bloating due to water retention, lowering your sodium levels can provide relief.



The National Kidney Foundation has an excellent list of foods that are high, medium, and low in potassium. Some of the most potassium-rich foods are:

  • Apricot
  • Avocado
  • Banana
  • Grapefruit juice
  • Oranges
  • Acorn squash
  • Artichoke
  • Baked beans
  • Brussels sprouts
  • Raw carrots
  • White mushrooms
  • Tomatoes
  • Chocolate
  • Granola
  • Milk

You'll notice that some items, such as milk and baked beans, are on both the list of gastric irritants and potassium-rich foods. That's why it's important to cross-reference the lists before adjusting your diet. Make sure that the changes you're making will have the effects you desire.


Natural Diuretics for Water Retention

By increasing blood flow to the liver, the caffeine in coffee helps the liver flush fluids from the body. That means that your cup of joe is one of the best foods that reduce water retention.


Water pills are another popular form of diuretics. You should be aware though, these pills can be problematic. They flush your system of essential electrolytes such as potassium and magnesium. These electrolytes are integral to your health, so if you plan to use water pills, make sure you're supplementing with potassium and magnesium.

Adopt the Mediterranean Diet

Another great source of anti-inflammatory foods is the Mediterranean diet. A study from the September 2016 issue of the Journal of Nutrition noted these effects of the diet. It also found that the diet helps people lose weight, which means that it'll cut your stomach girth in not just one but two ways.

The diet isn't just about eating Mediterranean foods, but it's also about how much of which types of foods you eat. Those who follow it eat more fruits, vegetables and seafood, while consuming a lot less dairy. It also limits your calories, which probably assists in that weight loss factor too.
