You may have grown up thinking that drinking lots of milk would give you strong bones, but it turns out that too much calcium can be harmful. If you have too much calcium in your blood, you have a condition called “hypercalcemia.” is a condition characterized by an elevated level of calcium in the blood. While calcium is essential for strong bones, teeth, muscle function, and nerve signaling, having too much can lead to various health problems. In this blog, we’ll delve into what it is, its causes, symptoms, its connection to kidney stones and chronic kidney disease (CKD), and how it can be managed.

What is Hypercalcemia?

Hypercalcemia occurs when the calcium level in your blood is above the normal range. This imbalance can affect various bodily functions and may lead to serious health issues if left untreated.

What are its Causes?

There are several potential causes:

  1. Overactive Parathyroid Glands: These glands, located in your neck near your thyroid, control calcium levels in your blood. If they produce too much of a specific hormone called parathyroid hormone (PTH), it can lead to high calcium levels.
  2. Cancer: Some cancers, such as lung, breast, and blood cancers, can cause high calcium levels in the blood.
  3. Other Medical Conditions: Diseases like tuberculosis and sarcoidosis can cause increased vitamin D levels, leading to higher calcium levels in the blood.
  4. Medications: Some medications, including lithium and certain diuretics, can elevate calcium levels.
  5. Excessive Supplementation: Taking too much calcium or vitamin D supplements can also result in hypercalcemia.
  6. Dehydration: Severe dehydration can concentrate calcium levels in the blood.

What are its Symptoms?

The symptoms can vary from mild to severe, and they often develop slowly. Common symptoms include:

  • Frequent Thirst and Urination: High calcium levels can cause the kidneys to work harder, leading to increased thirst and frequent urination.
  • Digestive Issues: These may include nausea, vomiting, constipation, and abdominal pain.
  • Bone Pain and Muscle Weakness: Excess calcium can lead to bone pain, muscle weakness, and overall fatigue.
  • Cognitive Changes: Confusion, memory problems, and depression can occur, particularly in severe cases.
  • Kidney Stones: High levels of calcium can lead to kidney stones, causing sharp pain in the back or abdomen area, blood in the urine, and frequent urination.

How it can impact Kidney Stones-

Kidney stones are hard deposits of minerals and salts that form inside the kidneys. When calcium levels are too high, calcium stones can develop. These stones can be incredibly painful and can lead to complications such as urinary tract infections and kidney damage. Symptoms of kidney stones include:

  • Severe pain in the back or side
  • Pain during urination
  • Pink, red, or brown urine
  • Nausea and vomiting
  • Frequent urination

Hypercalcemia and Chronic Kidney Disease (CKD)-

Chronic Kidney Disease (CKD) is a long-lasting condition where the kidneys gradually stop working properly. CKD can disrupt the balance of calcium and phosphate in the body, leading to secondary hyperparathyroidism, a condition where the parathyroid glands produce too much of a hormone in response to low calcium levels. This can result in elevated blood calcium levels. Managing CKD effectively is crucial to preventing complications such as hypercalcemia.

How to diagnose-

If it is suspected, a healthcare provider will typically perform a series of tests, including:

  • Blood Tests: To check calcium and parathyroid hormone (PTH) levels.
  • Urine Tests: To check for excess calcium.
  • Imaging Tests: Such as X-rays or bone density scans, to detect bone loss or other abnormalities.
  • Electrocardiogram (ECG): To check for heart-related issues that can arise from high calcium levels.

How to manage-

The treatment depends on its severity and underlying cause. Here are some common approaches:

  1. Hydration: Drinking plenty of water can help flush excess calcium out of the body. In serious cases, IV fluids might be needed.
  2. Medications: Depending on the cause, medications may be prescribed to manage calcium levels.
  3. Surgery: If hyperparathyroidism is causing hypercalcemia, surgery to remove the overactive parathyroid gland(s) may be recommended.
  4. Dietary Adjustments: Reducing calcium and vitamin D intake can help manage blood calcium levels. Avoiding high-calcium foods and supplements is often advised.
  5. Dialysis: In severe cases, especially in patients with kidney failure, dialysis may be required to remove excess calcium from the blood.
  6. Treating Underlying Conditions: Addressing the root cause, such as managing cancer or other underlying health conditions, is crucial for effectively treating hypercalcemia.

How to prevent-

Preventing involves regular monitoring and managing risk factors. Here are some tips:

  • Regular Check-ups: Especially for individuals with conditions that increase the risk of hypercalcemia, like hyperparathyroidism or CKD.
  • Stay Hydrated: Drinking plenty of fluids helps maintain normal calcium levels.
  • Monitor Supplement Intake: Be mindful of calcium and vitamin D supplements. Always take advice of a healthcare provider before starting any new supplement regimen.
  • Healthy Diet: A balanced diet with appropriate levels of calcium and vitamin D is important.

 

Conclusion

Hypercalcemia is a condition that requires attention and management to prevent serious health complications. By understanding the causes, symptoms, and treatment options, you can take proactive steps to maintain healthy calcium levels. If you suspect you have or are experiencing symptoms, it’s important to seek medical advice for proper diagnosis and treatment.

Maintaining a healthy lifestyle, staying hydrated, and regular medical check-ups can help keep it at bay. Always consult with healthcare professionals to tailor a plan that’s best for your individual health needs.
