High Potassium

Elevated potassium, known in medical terms as hyperkalemia, refers to a concentration of potassium in the blood above the usual values. Potassium is a mineral essential for the functioning of the heart, the nerves, and the muscles, so its excess can alter various functions of the body.

Who evaluates it? The nephrologist and the internist usually assess this imbalance, since it is frequently related to kidney function; the general practitioner can offer initial guidance and, in children, the pediatric nephrologist is involved.

Common causes: It can be associated with kidney alterations, with certain chronic conditions, or with changes in the way the body manages fluids and electrolytes.

Warning signs: Muscle weakness, a feeling of tiredness, or irregular heartbeats warrant attention. If you have these signs, it is worth having a professional review your case with the appropriate tests; in acute cases, an emergency evaluation may be needed.
