Understanding Hypermagnesemia in Cats
Hypermagnesemia, an excess of magnesium in the blood, is a rare but serious condition that can affect cats. It is important for cat owners to be aware of this electrolytic disorder and its potential implications. In this section, we will explore the rarity of hypermagnesemia in cats and the causes and risk factors associated with this condition.
Rare but Serious Condition
Hypermagnesemia is relatively uncommon in cats. However, when it does occur, it can have severe consequences if not promptly recognized and treated. The condition primarily affects cats with acute or chronic kidney disease. Conditions such as proton pump inhibitors, malnourishment, and alcoholism can increase the risk of developing hypermagnesemia in cats.
Causes and Risk Factors
There are various causes and risk factors associated with hypermagnesemia in cats. Increased intake of magnesium through sources like laxatives, antacids, and bowel preparation agents can lead to this condition, particularly in elderly cats with impaired renal function. Prolonged use of magnesium oxide, which has poor bioavailability but can still pose risks, may also contribute to hypermagnesemia in cats (NCBI Bookshelf).
Additionally, certain conditions and circumstances can increase the susceptibility of cats to developing hypermagnesemia. For example, cats with milk-alkali syndrome, which occurs due to the ingestion of large amounts of calcium and absorbable alkali, are more prone to this electrolyte disorder. Newborns of mothers who received magnesium sulfate parenterally during labor may also present with toxicity, even with normal serum magnesium levels (NCBI Bookshelf).
It is worth noting that certain medications and substances can contribute to the development of hypermagnesemia in cats. Severe hypermagnesemia has been observed after the administration of bowel preparation agents like sodium picosulphate magnesium citrate. Excessive oral intake of magnesium can also lead to hypermagnesemia in cats undergoing hemodialysis. In these cases, ingestion primarily influences plasma levels of magnesium.
While hypermagnesemia is uncommon in healthy cats, studies suggest a significant prevalence of high serum magnesium levels in selected healthy populations. In humans, hypermagnesemia has been associated with worse hospital mortality in individuals with cardiovascular disease. However, further research is needed to determine the specific implications of hypermagnesemia in cats (NCBI Bookshelf).
Understanding the rarity, causes, and risk factors associated with hypermagnesemia in cats is essential for cat owners. If you suspect that your cat may be experiencing this condition, it is important to seek veterinary care promptly to ensure appropriate diagnosis and treatment.
Diagnosis of Hypermagnesemia in Cats
When it comes to diagnosing hypermagnesemia in cats, veterinarians employ various methods to accurately assess magnesium levels and identify any underlying causes. The diagnosis typically involves laboratory tests and electrocardiography (ECG).
Laboratory Tests
Routine laboratory tests are crucial in diagnosing hypermagnesemia in cats. These tests include a complete blood count, biochemistry profile, and urinalysis to determine the levels of magnesium in the blood. Abnormally high levels of calcium are also found in affected cats. Urinalysis and other laboratory tests may reveal abnormalities related to an underlying disease, especially kidney problems.
Electrocardiography (ECG)
An electrocardiography (ECG) is an essential diagnostic tool used in cats with hypermagnesemia. This test allows veterinarians to monitor cardiac functions and detect any characteristic changes associated with elevated magnesium levels. As plasma magnesium concentrations exceed 2.5 mmol/L, ECG changes may be observed, such as prolongation of the PR interval. In severe cases, deep tendon reflexes disappear, followed by hypotension and respiratory depression. Cardiac arrest may even occur with blood magnesium levels exceeding 6.0-7.5 mmol/L.
These diagnostic tests aid in determining the presence and severity of hypermagnesemia in cats. They also help identify any underlying conditions contributing to the magnesium imbalance. Once a diagnosis is made, appropriate treatment strategies can be implemented to manage the condition effectively.

Treatment for Hypermagnesemia in Cats
When it comes to treating hypermagnesemia in cats, prompt intervention is necessary to prevent further complications. The treatment approach focuses on enhancing magnesium elimination and adding calcium therapy to restore the balance of minerals in the body.
Enhancing Magnesium Elimination
To enhance the elimination of excess magnesium from the body, several steps are typically taken. First, medications containing magnesium are discontinued to prevent further magnesium intake. Next, fluid therapy is initiated to increase urine production, which aids in flushing out the excess magnesium. This is achieved through the administration of intravenous fluids, which help to promote hydration and facilitate magnesium excretion (PetMD).
Adding Calcium Therapy
Adding calcium therapy is another crucial aspect of treating hypermagnesemia in cats. Calcium plays a vital role in regulating magnesium levels in the body. It helps to counteract the effects of excess magnesium by promoting its excretion. Calcium binds to magnesium in the gut, preventing its absorption and facilitating its elimination through the feces.
Calcium therapy is typically administered under the supervision of a veterinarian. It may involve the intravenous or subcutaneous administration of calcium gluconate or calcium chloride. The specific dosage and frequency will depend on the severity of the hypermagnesemia and the individual cat’s condition. It is essential to closely monitor calcium levels during this treatment to avoid complications associated with high calcium levels.
Proper treatment for hypermagnesemia in cats is crucial to prevent further complications and restore the balance of minerals in the body. The aim is to eliminate excess magnesium and restore normal magnesium and calcium levels. With prompt and appropriate treatment, the prognosis for cats with hypermagnesemia is generally favorable. However, it is important to closely monitor the cat’s condition and follow up with regular veterinary check-ups to ensure ongoing health and well-being.
In the next section, we will explore the prognosis and monitoring considerations for cats with hypermagnesemia, providing further insights into the long-term implications of this condition.
Prognosis and Monitoring

Prognosis Without Kidney Involvement
In cases of hypermagnesemia in cats without kidney involvement, the prognosis after initial therapy is excellent. With appropriate treatment, cats can experience a resolution of their hypermagnesemia. However, it’s important to note that the underlying cause of hypermagnesemia should be addressed to achieve a permanent resolution (PetMD).
It’s essential to work closely with your cat’s veterinarian to identify and treat any underlying issues contributing to the high magnesium levels. Regular monitoring of magnesium levels during and after treatment is crucial to ensure that the levels remain within a healthy range. If any untoward signs occur after discharge, immediate contact with the veterinarian is necessary to address any potential complications.
Importance of Monitoring
Monitoring plays a vital role in managing hypermagnesemia in cats. Regular laboratory tests, including blood chemistry panels, can help assess magnesium levels and monitor the effectiveness of treatment. Electrocardiography (ECG) may also be performed to evaluate cardiac function and detect any abnormalities.
By closely monitoring magnesium levels and cardiac functions, veterinarians can ensure that the treatment is on track and make any necessary adjustments to maintain optimal health for the cat. Monitoring allows for early detection of any potential complications or relapses, enabling prompt intervention to prevent further health issues.
It’s important to follow the veterinarian’s recommendations regarding follow-up visits and monitoring schedules. These regular check-ups will help ensure that your cat’s magnesium levels remain stable and that any underlying conditions are adequately managed.
