sind elektrolyte gesund — when to see a doctor?

Electrolytes (sodium, potassium, magnesium, calcium, chloride, phosphate) are essential for nerve function, muscle contraction, and fluid balance. With a normal diet and adequate hydration, they are healthy and self-regulated by the body. Problems arise only with significant imbalance—due to extreme sweating, vomiting, diarrhea, or kidney/heart conditions. See a doctor if you experience persistent muscle cramps, irregular heartbeat, confusion, severe fatigue, or if you take diuretics. Electrolyte drinks can benefit endurance athletes but are unnecessary for most people; excessive intake may cause harm (e.g., high sodium). Marketing often overstates benefits. Evidence: practice – based on basic physiology and clinical consensus.
