Patients with kidney stones can take oral calcium gluconate solution if they have an electrolyte test and there is a decrease in blood calcium, but if they are patients with stones. However, if the blood calcium test is completely normal, it is not necessary to take calcium gluconate orally, otherwise it can increase the calcium level in the body, and the calcium excreted from the kidney will increase, which may lead to further increase in the size of kidney stones or the formation of new stones, which is more commonly known as calcium deficiency and calcium supplementation, not calcium deficiency and no calcium supplementation, so as not to increase the probability of stone incidence. During the period of calcium supplementation, it is necessary to have regular electrolyte examination to understand the recovery of calcium level. If the calcium level returns to normal, the medication can be stopped. Patients with kidney stones can eat a normal diet, such as milk or eggs, which are relatively low in calcium and can only maintain the physiological requirements for one day after intake without causing excess. However, calcium supplementation with medication may lead to an overdose of calcium and promote the development of new stones, or lead to further increase in the size of existing stones.
