Hypokalemia

Hypokalemia is a disturbance in which the level of potassium in the blood is below normal. Because potassium takes part in muscle and nerve activity, its decline can affect the heart and the muscles.

When is it a good idea to seek care? It's a good idea to have it checked when muscle weakness, cramps, persistent fatigue, palpitations, or a sensation of irregular heartbeats appear, especially if you are taking diuretics or have prolonged vomiting or diarrhea.

Common causes: it is usually related to digestive or urinary losses of potassium, the use of certain medications, or some hormonal and kidney disorders.

Which specialist treats it? Its study falls to the internist and, depending on the origin, to endocrinology or nephrology; in severe cases, critical care medicine is involved. The most sensible thing is to discuss the symptoms with one of these professionals for an appropriate evaluation, rather than changing your diet or supplements on your own.
