Low Blood Pressure
While magnesium is known to help lower blood pressure, an overdose can lead to hypotension, characterized by dizziness, fainting, and, in severe cases, shock. This sudden drop in blood pressure can be dangerous, especially for individuals with underlying heart conditions. [3]
Urine Retention
Excessive magnesium can affect normal urinary function, leading to difficulty in urination. This condition can cause discomfort and, if not addressed, may lead to complications in the urinary tract.
