Patients with multiple calcium deposits should be diagnosed and treated early to minimize kidney damage and prevent the occurrence of renal failure. The onset of calcium deposition can be caused by disorders of vitamin D metabolism, and is also related to diet and environmental factors. For pediatric patients, reasonable feeding, more sun exposure, and active prevention of nutritional diseases should be promoted. Excessive intake of vitamin D causes calcium to combine with phosphorus, resulting in calcium deposition, prevention should drink more plain water, eat more black fungus, eat less cod liver oil, drink less milk before bedtime, eat less soy products, etc. Daily preventive measures: 1, more active people who do not like to move easily make calcium accumulation in the blood. Exercise helps calcium flow to the bones where it belongs. Do not sit around all day waiting for stones to form, you should walk or exercise outdoors. 2. Eat less salt If you have calcium deposits, you should reduce your salt intake. You should reduce your daily salt intake to 2-3 grams. 3, supplement nutrients ① magnesium oxide or magnesium chloride 500 mg per day. Reduce the absorption of calcium. Research found that daily magnesium, can reduce the recurrence rate of 90%. Because magnesium and calcium – the same, both can be combined with oxalic acid. However, unlike calcium oxalate, magnesium oxalate is less likely to form painful stones. ② Vitamin B6 10 mg twice a day. When used with magnesium, B6 reduces oxalate, a common mineral salt in kidney stones, in the urine. ③Proteolytic enzymes Dosage according to product directions, use between meals. Aids in normal digestion. ④Vitamin A emulsion or capsule 4. Pay attention to protein intake There is a direct correlation between kidney stones and the amount of protein intake. Protein tends to cause uric acid, calcium and phosphorus to appear in the urine, leading to stone formation. If you have had calcium deposits, you should pay special attention to excessive protein intake, especially if you have a history of excessive uric acid or cysteine stones. Limit yourself to 180 grams of high-protein foods per day, which includes meat, cheese, chicken and fish. 5. Do not eat foods rich in oxalates About 60% of stones are calcium oxalate deposits. Therefore, you should limit your intake of oxalate-rich foods, including beans, beets, celery, chocolate, grapes, peppers, parsley, spinach, strawberries and vegetables from the kale family. Also avoid alcohol, caffeine, tea, chocolate, dried figs, lamb, drupes, green peppers, black tea, and poppy seeds.
