What happens if someone has too much calcium?



Calcium is essential in maintaining healthy bones, teeth, and various bodily functions. However, an imbalance in calcium levels can adversely affect the body. This article explores the consequences of too much calcium in the body, including the causes, symptoms, and available treatments.

What happens if someone has too much calcium?

Understanding High Calcium Levels:

High calcium levels, medically known as hypercalcemia, occur when there is excessive calcium in the bloodstream. Hypercalcemia can result from various factors, such as:

  • Overactive Parathyroid Glands:

 Primary hyperparathyroidism, caused by an overactive parathyroid gland(s), leads to increased production of parathyroid hormone (PTH), resulting in elevated calcium levels.

  • Cancer: 

Certain cancers, such as lung, breast, kidney, or multiple myeloma, can release substances that trigger calcium release into the bloodstream.

  • Medications and Supplements:

 Excessive calcium intake or certain medications, such as thiazide diuretics or lithium, can contribute to high calcium levels.

Symptoms and Effects of High Calcium Levels:

The symptoms of hypercalcemia can vary depending on the severity and underlying cause. Common signs and effects include:

  • Fatigue and weakness
  • Excessive thirst and frequent urination
  • Digestive issues, including nausea, vomiting, and constipation
  • Abdominal pain and loss of appetite
  • Bone pain and increased risk of fractures
  • Kidney stones and urinary tract problems
  • Changes in mental health, including confusion and depression
  • Muscle weakness and spasms

If you experience persistent or severe symptoms, seeking medical attention for proper diagnosis and treatment is essential.

Diagnosis and Treatment Options:

To diagnose high calcium levels, a healthcare professional will perform various tests, including:

  • Blood Tests:

Measuring calcium levels and other blood markers can help confirm hypercalcemia and identify its underlying cause.


  • Imaging Tests: 

Imaging studies, such as X-rays or bone scans, may be performed to evaluate bone health and identify related conditions.


Treatment options for high calcium levels aim to address the underlying cause and restore normal calcium levels. Depending on the severity and cause of hypercalcemia, treatment may involve:

  • Fluids and Medications:

 Intravenous fluids can help rehydrate the body and encourage urinary calcium excretion. Medications like bisphosphonates or calcitonin may be prescribed to reduce calcium levels.

  • Managing Underlying Conditions:

Treating the underlying condition responsible for high calcium levels, such as parathyroid surgery for hyperparathyroidism or cancer treatment, is essential to normalize calcium levels.

Prevention and Long-Term Management:

To prevent high calcium levels, it is essential to maintain a balanced lifestyle and manage underlying health conditions effectively. Some preventive measures include:

  • Adequate Hydration:

 Drinking enough water helps maintain proper fluid balance and supports healthy kidney function.

  • Balanced Diet:

Following a balanced diet that includes sufficient but not excessive amounts of calcium and other essential nutrients can help prevent calcium imbalances.

  • Regular Monitoring: 

Individuals with high calcium levels should have regular check-ups and blood tests to monitor calcium levels and overall health.


High calcium levels, or hypercalcemia, can affect the body’s normal functioning. Recognizing the symptoms and seeking medical attention is crucial for diagnosis and treatment. Proper management involves addressing the underlying cause, restoring normal calcium levels, and preventing complications. By maintaining a balanced lifestyle, managing underlying conditions, and following healthcare professional guidance, individuals can effectively prevent and manage high calcium levels, promoting overall well-being. If you suspect high calcium levels or experience persistent symptoms, consult a healthcare professional for proper evaluation and personalized treatment.
