Magnesium is a vital mineral involved in numerous physiological processes, including muscle function, nerve transmission, and bone health. Below is a detailed overview of this condition, including its clinical description, causes, symptoms, diagnosis, and treatment options.

Clinical Description

Definition

ICD-10 code E83.4 refers to disorders related to magnesium metabolism, which can manifest as either hypomagnesemia (low magnesium levels) or hypermagnesemia (high magnesium levels). These disorders can lead to various health complications due to magnesium's critical role in enzymatic reactions and cellular functions.

Types of Disorders

1. Hypomagnesemia (E83.42): This condition is characterized by abnormally low levels of magnesium in the blood. It can result from inadequate dietary intake, gastrointestinal losses (such as diarrhea or malabsorption), renal losses (due to certain medications or kidney disease), or other underlying health issues.

2. Hypermagnesemia: This less common condition occurs when there is an excess of magnesium in the body, often due to renal failure, excessive intake of magnesium-containing supplements, or medications.

Causes

Hypomagnesemia

• Dietary Deficiency: Insufficient intake of magnesium-rich foods (e.g., nuts, seeds, whole grains).
• Gastrointestinal Disorders: Conditions like Crohn's disease or celiac disease can impair magnesium absorption.
• Renal Losses: Certain diuretics and conditions affecting kidney function can lead to increased magnesium excretion.
• Endocrine Disorders: Conditions such as hyperaldosteronism can also contribute to magnesium loss.

Hypermagnesemia

• Renal Failure: The most common cause, where the kidneys cannot excrete magnesium effectively.
• Excessive Supplementation: Overuse of magnesium-containing medications or supplements.
• Adrenal Insufficiency: Can lead to retention of magnesium.

Symptoms

Hypomagnesemia Symptoms

• Muscle cramps or spasms
• Weakness and fatigue
• Nausea and vomiting
• Abnormal heart rhythms (arrhythmias)
• Neurological symptoms such as numbness or tingling

Hypermagnesemia Symptoms

• Nausea and vomiting
• Flushing and warmth
• Muscle weakness
• Respiratory depression
• Cardiac arrest in severe cases

Diagnosis

Diagnosis of magnesium metabolism disorders typically involves:
- Blood Tests: Measuring serum magnesium levels to confirm hypomagnesemia or hypermagnesemia.
- Clinical Evaluation: Assessing symptoms and medical history to identify potential causes.
- Additional Tests: May include kidney function tests and electrolyte panels to evaluate overall metabolic status.

Treatment

Hypomagnesemia Treatment

• Dietary Changes: Increasing intake of magnesium-rich foods.
