Summary about Disease
Hypercalcemia is a condition characterized by an abnormally high level of calcium in the blood. Calcium is essential for many bodily functions, including bone health, muscle contraction, nerve function, and blood clotting. When calcium levels are too high, it can disrupt these processes and lead to various health problems.
Symptoms
Symptoms of hypercalcemia can range from mild and unnoticeable to severe. Common symptoms include:
Fatigue and weakness
Excessive thirst and frequent urination
Constipation
Bone pain
Nausea, vomiting, and loss of appetite
Muscle aches
Confusion, lethargy, and depression
Kidney stones
Cardiac arrhythmias
Causes
The most common causes of hypercalcemia are:
Hyperparathyroidism: Overactivity of one or more of the parathyroid glands, which regulate calcium levels.
Cancer: Certain cancers, such as lung cancer, breast cancer, and multiple myeloma, can release substances that cause hypercalcemia.
Medications: Thiazide diuretics, lithium, and calcium supplements can sometimes contribute to elevated calcium levels.
Other Medical Conditions: Sarcoidosis, tuberculosis, immobilization, vitamin D toxicity, and kidney disease can also lead to hypercalcemia.
Medicine Used
Treatment for hypercalcemia depends on the severity and underlying cause. Medications may include:
Calcimimetics: Cinacalcet reduces parathyroid hormone (PTH) levels, thus lowering calcium.
Bisphosphonates: Pamidronate, zoledronic acid inhibit bone breakdown, lowering calcium release.
Calcitonin: Counteracts the effects of PTH, helping to lower calcium levels.
Corticosteroids: Reduce inflammation and may be used when hypercalcemia is related to conditions like sarcoidosis.
Diuretics: Furosemide can help promote calcium excretion in the urine.
Intravenous Fluids: Hydration with saline solution can help dilute the calcium in the blood and increase its excretion.
Is Communicable
Hypercalcemia is not a communicable disease. It is not caused by an infectious agent and cannot be transmitted from person to person.
Precautions
Precautions depend on the underlying cause and severity. General recommendations include:
Hydration: Drink plenty of fluids to help keep calcium diluted in the blood.
Diet: Avoid excessive calcium intake from food and supplements unless specifically recommended by a doctor.
Medication Review: Discuss all medications and supplements with your doctor to identify potential contributors to hypercalcemia.
Regular Monitoring: If you have a condition that increases your risk of hypercalcemia, regular blood tests to monitor calcium levels are important.
How long does an outbreak last?
Hypercalcemia isn't an outbreak-related condition, so this question is not applicable. The duration of hypercalcemia depends on the underlying cause and how quickly it is addressed. Mild cases might resolve quickly with treatment, while chronic conditions may require ongoing management.
How is it diagnosed?
Hypercalcemia is diagnosed through a blood test that measures the level of calcium in the blood serum. The test can be part of a routine checkup or ordered if you have symptoms suggestive of hypercalcemia. If high calcium levels are detected, further testing may be performed to determine the underlying cause, such as parathyroid hormone (PTH) levels, vitamin D levels, and kidney function tests. Imaging tests may also be used to look for tumors or other abnormalities.
Timeline of Symptoms
The timeline of symptoms can vary greatly depending on the severity of the hypercalcemia and the individual.
Mild Hypercalcemia: May be asymptomatic or cause only mild, vague symptoms like fatigue. Can develop over weeks or months.
Moderate Hypercalcemia: Symptoms like excessive thirst, frequent urination, constipation, and bone pain may develop over several weeks.
Severe Hypercalcemia: Symptoms like confusion, lethargy, nausea, vomiting, and cardiac arrhythmias can develop rapidly, sometimes within days.
Important Considerations
Underlying Cause: Identifying and treating the underlying cause is critical for long-term management.
Severity: The severity of hypercalcemia dictates the urgency and intensity of treatment.
Complications: Untreated hypercalcemia can lead to serious complications such as kidney damage, kidney failure, osteoporosis, cardiac arrhythmias, and coma.
Individualized Treatment: Treatment plans should be tailored to the individual based on their overall health, other medical conditions, and medications.
Monitoring: Regular monitoring of calcium levels is important to ensure treatment is effective and to detect any recurrence of hypercalcemia.
