3. Fatigue and weakness
In most cases of potassium deficiency, fatigue is a known symptom. What do you think is the relationship of fatigue to potassium deficiency? As we mentioned earlier, potassium regulates blood flow through muscles. There is a lack of oxygen because there is no potassium to regulate the flow. Your body gets tired easily when there is a lack of oxygen. This weakens your muscles. This is why you feel tired.
Other than that, there is one more factor here. When there is a lack of potassium and oxygen, your heart is forced to pump blood faster. This puts pressure on your veins and arteries. It can burn tons of calories. As a result, you lose a lot of energy in the process. When you run out of energy, you are left with a tired and exhausted body.
