Hypercalcemia Symptoms

Symptoms of hypercalcemia is based on serum calcium concentration. According to serum calcium level, hypercalcemia can be divided into mild: serum calcium at 2.7 ~ 3.0mmol / L between; moderate: 3.0 ~ 3.4mmol / L between; severe: 3.4mmol / L or more.

1. Neuropsychiatric symptoms: light only fatigue; weight are headache, weakness, reduced tendon reflexes, depression, excitability, ataxia, language barriers, hearing or sight barriers, and loss of orientation, etc. Symptoms of severe hypercalcemia include delirium, convulsions, coma. Neuropsychiatric symptoms of high calcium is mainly toxic to brain cells.

2. Cardiovascular and respiratory symptoms: can cause high blood pressure and arrhythmia. If not treated in time, can cause fatal arrhythmias. Hypercalcemia due to increased drainage can cause kidney and electrolyte disorders, so that viscosity of bronchial secretions, mucosal cells, decreased ciliary activity, poor drainage of bronchial secretions, easily lead to pulmonary infection, dyspnea, or respiratory failure.

3. Digestive system symptoms: expressed as anorexia, nausea, vomiting, abdominal pain, constipation, severe paralytic ileus have occurred. Hypercalcemia are prone to peptic ulcer and acute pancreatitis.

4. Urinary tract symptoms: high blood calcium can cause renal tubular damage, renal tubular concentration function so that, in addition to substantial emissions of calcium from the urine, thus giving rise to polyuria, dehydration, electrolyte disorders and acid-base imbalance. Calcium deposition in the renal parenchyma can cause interstitial nephritis, nephrotic syndrome of salt loss. Kidney calcium deposition disease, eventually develop into renal failure.

5. Sign of calcium ectopic precipitation: hypercalcemia can lead to ectopic calcinosis in the vessel wall, corneal, conjunctival. Tympanic membrane, and cartilage around the joints, can cause muscle atrophy, corneal disease, red-eye syndrome, hearing loss and joint dysfunction.

6. Hypercalcemia crisis: increased calcium to 4mmol / L or more, the performance for many drinks, polyuria, severe dehydration, circulatory failure, azotemia. If not timely rescue, the patient may die of kidney failure and circulatory collapse.
