Hypermagnesemia is a rare condition where there's too much magnesium in your blood, often due to kidney problems or magnesium intake. Let's explore what causes it, its symptoms, and how it can be treated.

Causes of Hypermagnesemia
Hypermagnesemia primarily occurs when the kidneys can't remove excess magnesium due to kidney failure. It can also happen if you consume too much magnesium through supplements or medications. In some cases, gastrointestinal issues can lead to increased absorption of magnesium, contributing to the condition.
Symptoms of Hypermagnesemia
Symptoms can vary based on magnesium levels, starting with nausea, lethargy, and diminished reflexes. As levels rise, more severe symptoms like muscle paralysis, difficulty breathing, and heart problems can occur. It's crucial to recognize these signs early to prevent serious complications.

How is Hypermagnesemia Diagnosed?
Doctors diagnose hypermagnesemia through blood tests that measure magnesium levels. They may also check kidney function and review your medical history, particularly your use of magnesium-containing products. Prompt diagnosis is essential for effective treatment.
