As a health professional with expertise in nutrition, I can provide you with information on the potential side effects of excessive magnesium intake in the body. Excessive magnesium intake can lead to a condition known as hypermagnesemia, which is characterized by an abnormally high level of magnesium in the blood. The symptoms of magnesium overdose can range from mild to severe, depending on the level of excess and the individual's overall health. Mild symptoms may include: - Diarrhea - Nausea and vomiting - Lethargy - Muscle weakness More severe symptoms can include: - Irregular heartbeat (also known as arrhythmia) - Low blood pressure (hypotension) - Urine retention (difficulty urinating or an inability to urinate) - Respiratory distress (difficulty breathing) In extreme cases, hypermagnesemia can lead to life-threatening complications such as cardiac arrest or coma. It's important to note that these severe symptoms are more likely to occur in individuals with impaired kidney function, as the kidneys play a critical role in regulating magnesium levels in the body. To maintain a healthy magnesium level, it's best to consume a balanced diet that includes a variety of magnesium-rich foods and to consult with a healthcare provider before taking any supplements, especially for those with kidney issues or other health concerns. read more >>
