Introduction:
Hypercalcemia is a medical disorder characterized by an abnormal rise in calcium levels in the circulation. The typical range of calcium levels in the blood is between 8.5 and 10.5 mg/dL. When the amount crosses this range, it is referred to as hypercalcemia. A variety of underlying medical disorders or drugs can cause hypercalcemia. Hormones are essential in the control of calcium levels in the body. The parathyroid hormone (PTH) regulates calcium levels in circulation by boosting calcium absorption from the stomach and calcium reabsorption from the kidneys. Other hormones implicated in calcium control include vitamin D and calcitonin. If not treated immediately, hypercalcemia can lead to significant health consequences. It can harm the heart and blood vessels, induce kidney stones, and contribute to osteoporosis (causes bone weakness and brittleness). As a result, it is essential to understand the function of hormones in developing and maintaining hypercalcemia and the available therapeutic choices.
What Is Hypercalcemia?
Hypercalcemia is a medical disorder defined by a high calcium level in the circulation. Calcium is a mineral required for numerous bodily activities, including muscle and neuron function, blood clotting, and bone creation and maintenance. Hypercalcemia can be caused by several medical disorders or drugs, including hyperparathyroidism, cancer, some medications such as lithium, thiazide diuretics, and vitamin D supplements, and other uncommon medical conditions such as sarcoidosis (a disease characterized by the formation of small clumps of inflammatory cells in any part of the body). Fatigue, muscular weakness, disorientation, constipation, and renal issues are all symptoms of hypercalcemia. If not treated quickly, hypercalcemia can have significant health effects, such as heart and blood vessel damage, kidney stones, and osteoporosis. Treatment for hypercalcemia usually entails treating the underlying cause and may include drugs to lower calcium levels in the blood and other measures to maintain kidney function.
What Is the Role of Hormones in Hypercalcemia?
-
Hormones are essential in controlling calcium levels in the body, and their malfunction can lead to hypercalcemia.
-
The parathyroid hormone (PTH) regulates calcium levels in circulation by boosting calcium absorption from the stomach and reabsorption from the kidneys.
-
When the calcium level in the blood falls, the parathyroid glands produce more PTH, stimulating calcium absorption from the stomach and reabsorption of calcium from the kidneys, boosting the calcium level in the blood.
-
Vitamin D is also involved in calcium level management. It enhances the body's absorption of calcium from the intestines, allowing it to deposit calcium into the bones.
-
Hypercalcemia can be caused by excessive vitamin D production or overuse of vitamin D supplementation.
-
Calcitonin is a hormone generated by the thyroid gland that helps to reduce blood calcium levels by suppressing bone disintegration. In hypercalcemia, calcitonin serves as a counterweight to PTH, reducing the amount of calcium in the blood by boosting calcium excretion in the urine.

Hypercalcemia can be caused by excessive vitamin D production or abuse of vitamin D supplementation.

In hypercalcemia, calcitonin serves as a counterweight to PTH, reducing the amount of calcium in the blood by boosting calcium excretion in the urine.
What Are the Symptoms of Hormonal Hypercalcemia?
The symptoms of hormonal hypercalcemia might vary depending on the etiology and severity of the disorder. Among the most prevalent symptoms are the following:
-
High calcium levels in the circulation can impair muscular function, resulting in weakness and weariness.
-
Hypercalcemia can induce stomach discomfort, which can result in nausea and vomiting.
-
High calcium levels in the bloodstream can cause constipation by delaying food transit through the digestive system.
-
Because of the effect of elevated calcium levels on the brain, hypercalcemia can produce confusion and disorientation.
-
Hypercalcemia can induce dehydration by interfering with the regular functioning of the kidneys.
-
Hypercalcemia can harm the kidneys, resulting in kidney stones, renal failure, and other significant problems.
-
Because of calcium deposits in the bones, hypercalcemia can cause bone pain.
-
Due to the effect of elevated calcium levels on the digestive tract, hypercalcemia can induce a lack of appetite.
It is essential to point out that some patients with hypercalcemia may have no or just minor symptoms. As a result, even if one does not have symptoms, it is essential to consult a doctor if one believes they have hypercalcemia.
What Are the Treatment Plans for Hormonal Hypercalcemia?
The underlying etiology and the severity of the illness determine the course of treatment for hormonal hypercalcemia. The treatment's purpose is to reduce calcium in circulation and avoid problems. Among the most prevalent treatment options are:
-
Calcium in the bloodstream can be reduced by medications such as bisphosphonates, Calcitonin, and corticosteroids.
-
Intravenous fluids can enhance urine production and assist the body in eliminating extra calcium.
-
Dialysis may be required to remove excess calcium from the blood in severe hypercalcemia or kidney failure.
-
In severe cases of hyperparathyroidism (when the parathyroid glands produce a large amount of parathyroid hormone in the blood), surgery may be required to remove the parathyroid glands.
-
Patients with hypercalcemia may require supportive treatment such as vital sign monitoring, hydration, and electrolyte replacement.
-
In certain circumstances, lifestyle adjustments such as lowering or discontinuing the usage of hypercalcemia-causing drugs, eating a nutritious diet, and exercising might be part of the treatment strategy.
It is essential to highlight that the treatment strategy should be tailored to the underlying reason, the severity of the ailment, and the patient's general health. As the patient's condition evolves, the treatment may need to be altered or changed.
Conclusion:
If not treated quickly, hypercalcemia can have significant health effects, such as heart and blood vessel damage, kidney stones, and osteoporosis. Individuals should be aware of the signs of hypercalcemia and seek medical assistance if they feel they have the illness. Hypercalcemia symptoms can be alleviated with the correct diagnosis and therapy.
