Hypermagnesemia

Pathophysiology

Structure

• Magnesium (Mg): A vital mineral found in various foods and is crucial for enzyme function, muscle contraction, and nerve signaling.
• Body’s Magnesium Stores: Most magnesium is stored in bones and soft tissues, with only about 1% present in the blood.

Blood

• Normal Levels: The normal magnesium level in blood ranges from 1.7 to 2.2 mg/dL.
• Hypermagnesemia: Defined as magnesium levels greater than 2.6 mg/dL.

Nerve Supply

• Neuromuscular Function: Magnesium plays a critical role in nerve transmission and muscle contraction. High magnesium levels can disrupt these processes, leading to symptoms like weakness? or paralysis?.

Types of Hypermagnesemia

1. Acute? Hypermagnesemia: Rapid increase in magnesium levels, often due to supplements or medical conditions.
2. Chronic? Hypermagnesemia: Gradual increase, often associated with kidney? dysfunction.

Causes of Hypermagnesemia
