List Of High Potassium Foods To Avoid

People who are suffering from kidney problems have weakened renal function. Because their kidneys can’t process potassium efficiently, and thus, it gets accumulated in their blood. If too much potassium gets stored in your blood, this can be life-threatening. To treat kidney disease, doctors often recommend some medications that will uplift the level of potassium. If your body has excessive levels of potassium, you may feel fatigued or nauseous. If the potassium level spikes abruptly, you may experience breathing difficulties, chest pain, or heart palpitations. This condition is called hyperkalemia, which demands extensive medical care.
