10 Warning Symptoms of Hypermagnesemia: High Magnesium Levels in Blood

Introduction: Why Hypermagnesemia Matters

Hypermagnesemia, a condition characterized by high magnesium levels in the blood, may not be the first health issue that comes to mind. However, it’s essential to recognize its symptoms and understand the potential complications. In this article, we’ll explore the top 10 symptoms of hypermagnesemia to help you identify the warning signs and take appropriate action.


Magnesium is a crucial mineral for maintaining optimal health. It plays a vital role in several bodily functions, such as muscle and nerve function, regulating blood pressure, and supporting the immune system. However, too much magnesium can lead to a host of health problems.

Hypermagnesemia is often caused by excessive intake of magnesium supplements, impaired kidney function, or certain medications. While the condition is relatively rare, it’s crucial to recognize the signs and symptoms to prevent complications and ensure proper treatment.

In the following sections, we’ll delve into each symptom in detail, discuss its underlying causes, and provide practical tips for addressing the issue. So, let’s get started.

Symptom 1. Hypermagnesemia: Nausea and Vomiting

Hypermagnesemia: Nausea and Vomiting


When high levels of magnesium accumulate in the blood, the body may attempt to eliminate the excess through vomiting. Nausea and vomiting are among the first symptoms to emerge in cases of hypermagnesemia. This reaction can be accompanied by a general feeling of malaise, which can further impact one’s overall wellbeing.

The link between high magnesium levels and nausea can be attributed to the mineral’s effect on the gastrointestinal system. Magnesium can act as a natural laxative, drawing water into the intestines and increasing motility. This increased intestinal activity can cause discomfort and eventually lead to nausea and vomiting.

Dealing with nausea and vomiting caused by hypermagnesemia may involve reducing magnesium intake and seeking medical advice. If the symptoms persist or worsen, a healthcare professional may recommend further testing to determine the root cause and appropriate treatment.

It’s important to remember that nausea and vomiting can be indicative of various health issues, not just hypermagnesemia. If you experience these symptoms, it’s essential to consult a healthcare professional to rule out other potential causes and receive proper guidance. (1)
