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.
Hypercalcemia occurs most commonly in breast cancer, lymphoma, prostate cancer, thyroid cancer, lung cancer, myeloma, and colon cancer. [2] It may be caused by secretion of parathyroid hormone-related peptide by the tumor (which has the same action as parathyroid hormone), or may be a result of direct invasion of the bone, causing calcium ...
In addition to these key imbalances, vitamin D and calcium are also taken orally in case the alteration of vitamin D causes severe hypocalcaemia, this treatment has the goal of restoring physiological levels of calcium in the person. [56] Achieving better blood glucose level control if the person is diabetic. Blood pressure control.
Severe hypercalcaemia (above 15–16 mg/dL or 3.75–4 mmol/L) is considered a medical emergency: at these levels, coma and cardiac arrest can result. The high levels of calcium ions decrease the neuron membrane permeability to sodium ions, thus decreasing excitability, which leads to hypotonicity of smooth and striated muscle.
Familial hypocalciuric hypercalcemia (FHH) is an inherited condition that can cause hypercalcemia, a serum calcium level typically above 10.2 mg/dL; although uncommon. [1] It is also known as familial benign hypocalciuric hypercalcemia (FBHH) where there is usually a family history of hypercalcemia which is mild, a urine calcium to creatinine ratio <0.01, and urine calcium <200 mg/day ...
The study found that 15.3% of participants had mild cognitive impairment, and that women with mild cognitive impairment were more likely to report more severe menopause symptoms.
The predominant symptoms of hypercalcemia are abdominal pain, constipation, extreme thirst, excessive urination, kidney stones, nausea and vomiting. [3] [14] In severe cases where the calcium concentration is >14 mg/dL, individuals may experience confusion, altered mental status, coma, and seizure. [3] [14]
"In severe cases, it may cause seizures, coma or a purple rash." Infants may show different signs such as poor feeding, irritability, bulging of the soft spot on their head or lethargy. Noted ...
