Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5] The normal range of blood calcium is typically between 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), while levels less than 2.1 mmol/L are defined as hypocalcemic. [1] [3] [6] Mildly low levels that develop slowly often have no symptoms.
In a healthy physiology, extracellular calcium levels are maintained within a tight range through the actions of parathyroid hormone, vitamin D and the calcium sensing receptor. [1] Disorders in calcium metabolism can lead to hypocalcemia, decreased plasma levels of calcium or hypercalcemia, elevated plasma calcium levels.
Hypocalciuria is a low level of calcium in the urine. It is a significant risk factor for predicting eclampsia in pregnancy. [1] The most common causes for hypocalciuria is either thiazide diuretics or reduced dietary intake of calcium. The other cause is Familial hypocalciuric hypercalcemia (FHH). Low dietary sodium causes hypocalciuria.
If the underlying cause of the hypocalcemia can be addressed, the hyperparathyroidism will resolve. In people with chronic kidney failure, treatment consists of dietary restriction of phosphorus; supplements containing an active form of vitamin D, such as calcitriol, doxercalciferol, paricalcitol; and phosphate binders, which are either calcium-based and non-calcium based.
Secondary hyperparathyroidism is due to physiological (i.e. appropriate) secretion of parathyroid hormone (PTH) by the parathyroid glands in response to hypocalcemia (low blood calcium levels). The most common causes are vitamin D deficiency [47] (caused by lack of sunlight, diet or malabsorption) and chronic kidney failure.
Hyperphosphatemia causes acute kidney injury in tumor lysis syndrome, because of deposition of calcium phosphate crystals in the kidney parenchyma. [2] Hypocalcemia. Because of the hyperphosphatemia, calcium is precipitated to form calcium phosphate, leading to hypocalcemia. [2] Symptoms of hypocalcemia include (but are not limited to): [9] tetany
Persistent low levels of circulating calcium are thought to be the catalyst in the progressive development of adenoma, in the parathyroid glands resulting in primary hyperparathyroidism. While primary hyperparathyroidism is the most common form of this condition, [ 2 ] [ 3 ] [ 4 ] secondary and tertiary are thought to result due to chronic ...
The main symptoms of hypoparathyroidism are the result of the low blood calcium level, which interferes with normal muscle contraction and nerve conduction.As a result, people with hypoparathyroidism can experience paresthesia, an unpleasant tingling sensation around the mouth and in the hands and feet, as well as muscle cramps and severe spasms known as "tetany" that affect the hands and feet ...
