What is the symptom of hypercalcemia?

summary

Hypercalcemia refers to the abnormal increase of serum ionic calcium concentration. Hypercalcemia occurs when the amount of calcium entering the extracellular fluid (intestine and bone) exceeds the amount of calcium excreted (intestine and kidney), and the blood calcium concentration is higher than 2.75 mmol / L. There are two main causes of hypercalcemia: PTH dependent and non PTH dependent hypercalcemia. What is the symptom of hypercalcemia? Next, I'd like to share my views with you.

What is the symptom of hypercalcemia?

Symptom 1: the light one is only weak, tired and indifferent; Severe patients have headache, muscle weakness, weakened tendon reflex, depression, irritability, gait instability, language disorders, hearing, vision and orientation disorders or loss, numbness, behavioral abnormalities and other mental and neurological symptoms. Delirium, convulsion and coma may appear in hypercalcemia crisis. Neuropsychiatric symptoms are mainly caused by the toxicity of high calcium to brain cells, which can interfere with the electrophysiological activities of brain cells.

Symptom 2: can cause blood pressure to rise and all sorts of arrhythmia. ECG showed Q-T interval shortening, ST-T changes, atrioventricular block and hypokalemic U wave. If not treated in time, it can cause fatal arrhythmia. Hypercalcemia can lead to increased renal micturition and electrolyte disorder, thickening of bronchial secretions, weakening of ciliary activity of mucosal cells, and poor drainage of bronchial secretions, which can easily lead to pulmonary infection, dyspnea, and even respiratory failure.

Symptom 3: loss of appetite, nausea, vomiting, abdominal pain, constipation, severe paralytic intestinal obstruction. Calcium can stimulate the secretion of gastrin and gastric acid, so patients with hypercalcemia are prone to peptic ulcer. The ectopic deposition of calcium in pancreatic duct and the stimulation of pancreatic enzyme secretion by calcium can lead to acute pancreatitis.

matters needing attention

1. It is rich in vitamin C and citric acid, which can reduce the formation of hypercalcemia. The calcium element entering the body can precipitate calcium citrate and reduce the absorption of calcium. 2. Avoid high calcium food; Avoid food with high content of D element; Avoid food with high phosphorus content.
