Background – Calcium Specialist in Maryland

As an endocrinologist dedicated to serving my community, I specialize in diagnosing and managing calcium disorders. My primary objective is to deliver personalized and integrative care to my patients.

Conveniently located in Rockville, my practice provides both virtual and in-person services, extending support to individuals in nearby areas such as Chevy Chase, Bethesda, North Bethesda, Potomac, North Potomac, Gaithersburg, Germantown, Frederick, Silver Spring, Northern Virginia, Western MD, and the Eastern Shore of Maryland for comprehensive care.

Here I introduce a summary on calcium disorders in simple terms. For a more comprehensive review, you can refer to the article “Calcium Disorders Specialist“.

Calcium Disorders, Defined

Calcium disorders refer to disruptions in the normal balance of calcium levels in the body, leading to either excess or insufficient amounts of this essential mineral. Calcium plays a crucial role in various physiological processes, including bone health, muscle function, nerve transmission, and blood clotting. Maintaining a delicate balance of calcium is essential for overall health, and any disturbances in this equilibrium can have significant consequences.

Calcium Regulation

Calcium homeostasis is tightly controlled by the endocrine system, primarily involving the parathyroid hormone (PTH), calcitonin, and vitamin D. These regulators work in harmony to ensure that calcium levels in the blood remain within a narrow range. The parathyroid glands release PTH in response to low blood calcium levels, stimulating the release of calcium from bones, enhancing calcium absorption in the intestines, and promoting calcium retention by the kidneys. On the other hand, calcitonin, released by the thyroid gland, acts to lower blood calcium levels by preventing bone breakdown.

Two Types of Calcium Conditions

Hypercalcemia and hypocalcemia are the two primary categories of calcium disorders, each presenting its own set of symptoms and complications. 


Hypercalcemia refers to elevated levels of calcium in the blood, often caused by conditions such as hyperparathyroidism, certain cancers, excessive vitamin D intake, or kidney disorders. The excess calcium can lead to symptoms like fatigue, nausea, constipation, muscle weakness, and confusion. Severe cases may result in kidney stones, heart rhythm abnormalities, or even coma.


Conversely, hypocalcemia denotes insufficient calcium levels in the blood and can be caused by a range of factors, including hypoparathyroidism, vitamin D deficiency, malabsorption disorders, or chronic kidney disease. Symptoms of hypocalcemia can manifest as muscle spasms, tingling or numbness in the extremities, seizures, and in severe cases, it may lead to tetany—a condition characterized by prolonged muscle contractions.

Central Participants in Calcium Regulation and Dysfunction

Parathyroid Glands

One of the primary causes of calcium disorders is dysfunction in the parathyroid glands. Hyperparathyroidism, characterized by overactivity of these glands, leads to excessive PTH release, resulting in increased calcium levels. This condition is often caused by benign tumors on the parathyroid glands. Surgical intervention to remove these tumors is a common treatment approach. On the other hand, hypoparathyroidism, where the glands are underactive, leads to decreased PTH production, causing reduced calcium levels. This condition can be congenital or result from surgical procedures involving the thyroid or parathyroid glands.

Vitamin D

Vitamin D plays a crucial role in dietary calcium absorption by the intestines, and deficiencies can contribute to hypocalcemia. Inadequate sunlight exposure, dietary deficiencies, or malabsorption issues can lead to insufficient vitamin D levels. Rickets in children and osteomalacia in adults are conditions associated with severe vitamin D deficiency, characterized by weakened and deformed bones.

Chronic Kidney Disease (CKD)

Chronic kidney disease can also disrupt calcium balance. The kidneys play a vital role in excreting excess calcium from the body. In kidney disorders, this regulatory function may be compromised, leading to hypercalcemia. Conversely, impaired kidney function can result in decreased activation of vitamin D, contributing to hypocalcemia.


Managing calcium disorders involves addressing the root cause and restoring the balance of calcium in the body. This may include medications, dietary adjustments, and, in some cases, surgical interventions. Monitoring and treating associated complications, such as kidney stones or bone abnormalities, are also crucial aspects of management.


In essence, calcium disorders pose significant challenges to overall health due to the fundamental role calcium plays in various physiological processes. Understanding the causes, symptoms, and potential complications of hypercalcemia and hypocalcemia is essential for timely diagnosis and effective management. Maintaining a delicate balance in calcium levels is vital for the proper functioning of the body and prevention of long-term complications associated with these disorders.
