Side effects: hypocalcemia

In rare cases, blood calcium levels may decrease, resulting in recurrence of hypocalcemia. Hypocalcemia is a phenomenon in which blood calcium is lower than normal and is a calcium metabolism disorder. Since the physiological effects of calcium depend on free calcium (i.e. ionized calcium), hypocalcemia generally refers to low ionized calcium, also known as free calcium below normal values.

Treatment: Severe hypocalcemia may lead to hypocalcemic crisis, which is life-threatening and requires active treatment. Calcium supplementation should be timely. If the effect of calcium supplementation is not good, you should pay attention to whether you have hypomagnesemia and supplement magnesium if necessary. As symptoms improve, you can switch to a high-calcium diet and take oral calcium supplements plus vitamin D (nutritional vitamin D or active vitamin D).
