This is a seemingly contradictory and interesting question: Is it possible to take calcium supplements in patients with kidney stones and should they avoid a high-calcium diet? How to prevent osteoporosis in people with kidney stones? This question has been debated in the medical community and many physicians have very different views. Whenever patients ask this question, many physicians do not even know how to answer. In the past, it was thought that people in areas with higher “hardness” (more calcium carbonate or magnesium carbonate) in their drinking water were more prone to stones, but it has been found that this is not the case, instead, people with a high oxalic acid diet (who eat spinach or tea that has been steeped for too long) are more prone to stones. If you don’t take calcium supplements at all, if your blood oxalic acid is high, you will still get calcium from the bones and turn it into stones. Therefore, the way to prevent stones is to reduce the intake of oxalic acid food. If we do not take calcium supplements, not only the normal physiological function will be affected, but also osteoporosis (osteoporosis) will develop in the long run. Finally, in order to get rid of the stones that may exist in our body, we should use the principle of competition between the anions in different salts, drink more drinks containing citric acid, or eat more fruits to take in citric acid in fruits, so that the citrate root can compete with the calcium ions in oxalate to produce free oxalate root and reduce the accumulation of insoluble calcium oxalate, which can also reduce the occurrence of stones. In addition, if you take calcium supplements, try to buy calcium citrate containing citrate root, which also has the same effect.
