According to the National Kidney Foundation, high potassium (also known as "hyperkalemia") is a medical condition where a person has too much of the crucial nutrient potassium in their blood, which is present in many meals. Potassium aids in the proper functioning of the heart, nerves, and other muscles, but too much potassium in the blood can be harmful and lead to major heart issues.
The is expected to continue to grow in the coming years, driven by factors such as the increasing prevalence of kidney disease, rising awareness about the condition, and advancements in treatment options.
High potassium levels can result in life-threatening cardiac arrhythmias, muscular weakness, or paralysis even though mild hyperkalemia is typically asymptomatic. Normal symptom onset values are 6.5-7 mEq/L, but the rate of change is more significant than the exact value. Patients with sudden, transient potassium shifts may experience severe symptoms at lower levels, while patients with persistent hyperkalemia may be asymptomatic at greater levels. Infants have higher baseline levels than children and adults.
