6 Alarming Signs That You Have A Potassium Deficiency


A potassium deficiency is easy to overlook, but it can carry very unpleasant consequences. Learn to recognize the signs:

Potassium. The body just can't do without it, but some of us carry a potassium deficiency without even realizing it. Even if you are getting the recommended 4,700mg of potassium a day in your diet, a high sodium diet could be undoing all your hard work as the more sodium you consume, the more potassium your body excretes. 

Here are some critical signs that you might have a potassium deficiency. 

Painful, achey joints and muscles

Atheltes are advised to keep a close eye on their potassium levels, as potassium is essential in the prevention of muscle cramps. The same is true for regular people too. Other signs of low potassium levels are limb weakness and achey joints. 

Excessive thirst

If you're drinking frequently and producing plenty of urine, but still feel constantly thirsty... then it's possible you are low in potassium!

Fluctuating blood pressure

Potassium regulates blood pressure by 'relaxing' blood cell walls, so if the level of potassium dips, blood pressure can soar. If you notice that your blood pressure is fluctuating, you may need to check your potassium levels. 


Low potassium levels slow down all of the body's regular functions, including the digestive system. If you are suffering from constipation, bloating or abdominal cramping, you should check your potassium levels. 


If you're feeling contstantly wiped out and tired, but you know you're getting enough sleep, then a potassium deficiency might be the cause. Potassium is essential to proper cell function, so when the levels dip, you'll feel it absolutely everywhere. 

What can you do to keep your potassium levels healthy?

If you notice any of these symptoms, you should consult your doctor.

In the meantime, we all know that bananas have high levels of potassium, but so do plenty of other foods. Did you know that all of these following foods contain more potassium than a banana? 

Sweet potato, avocado, white beans, yogurt, and spinach
