Hypomagnesemia s/s pattern?

Hypomagnesemia s/s pattern?

• A. Everything high
• B. Everything low
• C. Sedative-like signs
• D. Seizures

Answer: (A)

Magnesium helps keep nerves and muscles calm, so when it’s deficient the body tends toward neuromuscular excitability rather than suppression. Hypomagnesemia commonly presents with signs like tremors, hyperreflexia, and especially seizures. Seizures are a classic clue because low Mg removes a stabilizing influence on neuronal activity, leading to abnormal discharges. Sedative-like signs occur when magnesium is high, since excess Mg depresses neuromuscular transmission. So the pattern you’d expect with low magnesium is seizure activity, not everything being high or low or a generalized sedative profile.
