The Fifth Sign: Irregular Heartbeats and Sudden Palpitations.
Few sensations provoke as much immediate anxiety as a fluttering, racing, or skipping heartbeat. Because your heart is essentially a complex, continuously working muscle, it depends heavily on a delicate balance of electrolytes—including potassium, calcium, and magnesium—to maintain a steady electrical rhythm.
A magnesium deficiency disrupts this internal pacemaker, causing arrhythmias that can leave you feeling lightheaded, breathless, or dizzy. For older adults, these dizzy spells drastically increase the risk of dangerous falls and require immediate medical evaluation.
