Symptoms of potassium deficiency

Potassium is one of the most important minerals for our body. Its absence causes a number of problems. Potassium is important for the functioning of the cardiovascular system, plays an important role in muscle function and is essential for proper digestion.

Improper nutrition leads to potassium deficiency, which poses serious he alth risks.

What are the symptoms of potassium deficiency?

High blood pressure

Sodium causes an increase in blood pressure values. Potassium, on the other hand, has the property of lowering it. If you suffer from a lack of potassium, there is a possibility that your blood pressure will rise further, and cardiovascular function will be impaired.


Muscle Cramps

Muscle spasms can be seen with both magnesium and potassium deficiency. Potassium plays an important role in communication between nerve cells innervating muscle tissue. Its absence or greatly reduced amount of potassium in the blood leads to cramps.

Muscle weakness

In addition to cramps, a lack of potassium can also cause muscle weakness. The sufferer experiences difficulty in performing ordinary activities such as opening boxes, lifting light to moderate weights, holding the limbs in a certain position.

Severe fatigue

Fatigue occurs in many different he alth conditions. Lack of potassium is one of them. Sufferers of such a deficiency feel exhausted, unable to withstand exertion and feel a strong lack of energy.


Vertigo and dizziness are also possible with potassium deficiency. This condition is compensated by consuming potassium-rich foods.



Potassium is involved not only in the work of muscles, but also of joints and bones. That is why, with its insufficient amounts in the body, a feeling of stiffness can also be observed when moving.


Since potassium is directly related to the work of the digestive system, its lack can make the intestines sluggish and cause constipation. In addition, swelling, gas, discomfort in the abdominal area may appear.

Arrhythmia and extrasystoles

Potassium plays an important role in the overall functioning of the cardiovascular system, so its reduced amount can cause skipping of beats (extrasystoles) or arrhythmia (heart rhythm disturbances), in which the pulse may be too fast (tachycardia) or too slow (bradycardia).

Frequent urination

Potassium deficiency also causes disorders in the work of the urinary tract. This is why the condition can be confused with urinary tract infections or cystitis. It is important to consult a doctor if you notice any of the symptoms.
