Hypercalcemia Symptoms: Hypercalcemia, characterized by an elevated calcium level in the blood, is a condition that can lead to significant health issues if left unmanaged.
In this comprehensive article, we delve into the symptoms and causes of hypercalcemia, providing detailed insights to help you understand and manage this condition effectively.
What is Hypercalcemia?
Hypercalcemia refers to a condition where there is an abnormally high level of calcium in the bloodstream. Calcium, a vital mineral in the human body, is essential for maintaining strong bones and teeth, as well as supporting muscle function, nerve signaling, and heart health. When the calcium level in the blood exceeds normal, it can disrupt these critical processes.
The Importance of Calcium in the Body
Calcium plays a pivotal role in various bodily functions. It helps in the formation and maintenance of bones and teeth, making it crucial for skeletal structure and health. Beyond that, calcium is key in muscle contraction, enabling our muscles to move and respond to signals from the nervous system. It also contributes to blood clotting and regulates heart rhythms, making it indispensable for cardiovascular health.
How Hypercalcemia Occurs
Hypercalcemia occurs when there is too much calcium in the blood. This excess can stem from several sources:
- Overactive parathyroid glands (hyperparathyroidism), which are responsible for regulating calcium levels in the body.
- Cancer, particularly lung, breast cancer, or cancers that affect bones, which may increase calcium release into the bloodstream.
- Excessive intake of calcium or vitamin D from dietary sources or supplements, surpassing the body’s ability to excrete or absorb these nutrients effectively.
- Certain medications and medical treatments that can alter calcium levels or its metabolism.
However, understanding hypercalcemia is crucial because its effects can be severe, impacting various organ systems and leading to complex health issues if not managed properly. Detecting and addressing the causes of hypercalcemia early is key to preventing serious complications.

Causes of Hypercalcemia
Understanding the causes is crucial for proper diagnosis and treatment. Here are the main causes of hypercalcemia:
Primary Hyperparathyroidism
Primary hyperparathyroidism is the most common cause of hypercalcemia. It occurs when one or more of the parathyroid glands become overactive, releasing excessive amounts of parathyroid hormone (PTH). This hormone increases calcium levels in the blood by promoting calcium release from bones, absorption from the intestines, and retention by the kidneys.
Cancer-Related Hypercalcemia
Cancer can also lead to hypercalcemia, often referred to as hypercalcemia of malignancy. Certain types of cancer, such as lung, breast, and multiple myeloma, can produce substances that mimic PTH or cause bone breakdown, leading to increased calcium levels in the blood.
Other Medical Conditions
Several other medical conditions can contribute to elevated calcium levels:
- Sarcoidosis: This inflammatory disease causes granulomas to form in various organs, which can produce vitamin D and increase calcium absorption.
- Tuberculosis: Similar to sarcoidosis, tuberculosis can lead to the formation of granulomas that elevate calcium levels.
Medications
Certain medications can also induce hypercalcemia:
- Thiazide Diuretics: These drugs, used to treat hypertension, can decrease calcium excretion by the kidneys, leading to higher blood calcium levels.
- Lithium: Commonly used to treat bipolar disorder, lithium can affect the parathyroid glands and increase calcium levels.
- Excessive Vitamin D or Calcium Intake: High doses of vitamin D supplements or excessive dietary calcium can lead to hypercalcemia, as they increase calcium absorption from the intestines.
Identifying the cause of hypercalcemia is essential for effective treatment. If you suspect you have hypercalcemia, consult with a healthcare professional for appropriate testing and management.
Risk Factors for Hypercalcemia
Age and Gender Considerations
Hypercalcemia, a condition characterized by elevated calcium levels in the blood, can affect people of all ages. However, certain age groups are more susceptible. Older adults are particularly at risk due to age-related changes in calcium metabolism and an increased likelihood of underlying health conditions. Additionally, postmenopausal women are at a higher risk due to decreased estrogen levels, which can affect bone resorption and calcium balance.
Genetic Predisposition
Genetic factors play a significant role in the likelihood of developing hypercalcemia. Individuals with a family history of hypercalcemia or related conditions, such as hyperparathyroidism or certain types of cancer, are at a higher risk. Inherited genetic mutations can affect calcium regulation in the body, leading to increased calcium levels in the bloodstream.
Lifestyle Factors
Lifestyle choices can significantly impact the risk of developing hypercalcemia. Key factors include:
- Diet: A diet excessively high in calcium, such as overconsumption of dairy products or calcium supplements, can contribute to elevated calcium levels.
- Physical Activity: Lack of physical activity can negatively affect bone health and calcium metabolism, increasing the risk of hypercalcemia.
- Hydration: Chronic dehydration can concentrate calcium in the blood, leading to hypercalcemia.
- Medications: Certain medications, such as lithium and thiazide diuretics, can increase calcium levels in the blood.
However, understanding these risk factors can help in the early detection and management of hypercalcemia, ensuring better health outcomes.
Diagnosis of Hypercalcemia
Medical History and Physical Examination
Diagnosing hypercalcemia begins with a thorough medical history and physical examination. Your healthcare provider will ask about your symptoms, medical history, and any medications you are taking. They will also perform a physical exam to check for signs of hypercalcemia, such as bone tenderness or abnormal heart rhythms.
Blood Tests
Blood tests are crucial in diagnosing hypercalcemia. The primary blood tests include:
- Calcium Levels: This test measures the amount of calcium in your blood. Elevated levels may indicate hypercalcemia.
- Parathyroid Hormone (PTH) Levels: High levels of PTH can be a sign of hyperparathyroidism, a common cause of hypercalcemia. This test helps determine if the parathyroid glands are contributing to the elevated calcium levels.
Imaging Tests
Imaging tests are often used to identify the underlying cause of hypercalcemia and assess any complications. Key imaging tests include:
- X-rays: These can detect bone abnormalities and calcium deposits in tissues.
- CT Scans: A CT scan provides detailed images of the body’s internal structures, helping to identify any tumors or other abnormalities that might be causing hypercalcemia.
- Bone Density Tests: These tests measure the density of your bones and can help detect osteoporosis or other bone conditions associated with hypercalcemia.
By combining information from medical history, physical examination, blood tests, and imaging tests, healthcare providers can accurately diagnose hypercalcemia and determine its underlying cause. Early diagnosis is crucial for effective treatment and management of this condition.
Treatment Options for Hypercalcemia
Hypercalcemia, characterized by an abnormally high level of calcium in the blood, requires different treatment approaches based on the severity of the condition. Here, we outline treatment options for both mild and severe cases of hypercalcemia.
Treatment for Mild Hypercalcemia
- Hydration: Increasing fluid intake, particularly water, can help flush excess calcium from the body through the kidneys.
- Dietary Changes: Reducing calcium-rich foods, such as dairy products, and avoiding supplements that contain calcium or vitamin D can help manage calcium levels.
- Medications: Certain medications, like diuretics (excluding thiazides), can help reduce calcium levels by increasing urine production.
- Monitoring: Regular blood tests to monitor calcium levels can help ensure that they remain within a safe range.
Treatment for Severe Hypercalcemia
- Intravenous Fluids: Administering IV saline can help rehydrate the body and promote the excretion of excess calcium.
- Bisphosphonates: These drugs can help inhibit bone resorption, thereby lowering calcium levels. Common bisphosphonates include pamidronate and zoledronic acid.
