Although bloating can occur for multiple reasons – such as stress or hormonal imbalance – in some cases, it can be due to hypokalemia aka low potassium.
Potassium is a nutrient that affects the digestive system in multiple ways, especially when it comes to muscle contractions and water retention.
So, to help you get a better understanding about how all of this ties to bloating, this article will cover:
- the correlation between potassium and bloating.
- some of the best food sources of potassium.
- how much potassium you actually need for good health.
Let’s dive in!
CAN POTASSIUM REDUCE BLOATING?
Potassium can play a role in reducing bloating because it is essential for:
- Balancing fluid levels: potassium is responsible for maintaining fluid levels inside our cells, while sodium maintains fluid levels outside the cell (source). However, when we take in too much sodium or we have low potassium, we can end up with sodium inside our cells. Not only does this create an imbalance in the overall potassium-sodium ratio, but it leads to water retention and a bloated appearance.
- Peristalsis: peristalsis is a process that involves the contraction of muscles along the digestive tract. When these contractions occur in the colon, it allows us to get rid of waste. However, if we have low potassium – aka hypokalemia – those contractions don’t happen as easily. Ultimately, this leads to constipation and a bloated appearance.
So, by increasing your potassium intake you can bring more balance to the body’s sodium-potassium ratio, encourage the elimination of excess sodium and ease constipation, all of which helps to ease to bloating.
POTASSIUM-RICH FOODS TO REDUCE BLOATING
The richest source of potassium is plants, particularly fruits and vegetables. At the end of this section I’ve included a table with 27 potassium-rich foods that you can add to your diet (source).
Please keep in mind that these foods contain other compounds that can contribute to bloating in some people.
For example, beans contain raffinose, an indigestible starch that can trigger bloating and gas.
In addition, the lactose in dairy can also cause bloating for some people.
So, as you make changes to your diet, you’ll want to prioritize foods that are potassium-rich and agreeable for your particular digestive system.

CAN TOO MUCH POTASSIUM CAUSE BLOATING?
High potassium – aka hyperkalemia – can have an inhibitory effect on the muscular contractions in the digestive tract. As a result, the muscles of the colon become too weak to contract effectively. Ultimately, this can lead to digestive issues like bloating, gas, diarrhea and more (1, 2, 3).
Aside from the above, elevated potassium levels can also cause muscle cramps, weakness and irregular heartbeat (source).
