The lack of calcium ions in the blood can be caused by dietary factors, excessive loss of calcium ions, vitamin D deficiency, increased body demand, hypoparathyroidism, kidney failure and so on.
1. Dietary factors: such as long-term consumption of strong tea, carbonated beverages, coffee, etc., can affect the absorption of calcium ions in the body, the symptoms of calcium deficiency.
2. Excessive loss of calcium ions: such as menopausal syndrome, due to the reduction of estrogen in the body, the loss of calcium ions in the bones is more, if not timely calcium supplementation treatment, it may cause symptoms of calcium deficiency, which can cause osteoporosis.
3. Vitamin D insufficiency: Vitamin D can promote the absorption of calcium ions, when vitamin D decreases in the body, it can lead to the symptoms of calcium deficiency, which can be supplemented with vitamin D in time.
4. Increased body demand: children in growth and development period, the body needs more calcium ions, if there is no timely supplementation, there will also be symptoms of calcium deficiency, lower blood calcium.
5. Hypoparathyroidism: caused by surgery, heredity, autoimmune, drug damage, etc. The main clinical symptoms include hypocalcemia and hyperphosphatemia, etc. Decreased blood calcium can cause symptoms such as hypocalcemic convulsions.
6. Renal failure: renal synthesis of vitamin D3 decreases significantly in renal failure, and water-electrolyte disorders lead to hyperphosphatemia, resulting in hypocalcemia.
When the symptoms of calcium deficiency appear, according to the clinical symptoms of the patient, further examination to confirm the diagnosis, to find out the causes of calcium deficiency, targeted treatment.
