Lateral ventricular widening does not need to stop taking calcium tablets because it has nothing to do with calcium supplementation. Most of the widening of lateral ventricles is caused by hydrocephalus, which is a symptom that occurs when hydrocephalus gathers in the lateral ventricles, and is not caused by calcium supplementation. If the widening of the lateral ventricles is not obvious, it usually does not affect much, and does not need any special treatment, but if the widening is more serious, you should go to the hospital for regular review at the late stage of pregnancy. During pregnancy, women are prone to calcium deficiency due to their own needs as well as the growth and development of the fetus, so they need to take calcium supplements, such as calcium lactate and calcium carbonate, as prescribed by the doctor. Widening of the lateral ventricles requires regular checkups in the hospital. If the widening is severe, it may indicate that the fetus has abnormal development of the central nervous system, and the pregnancy may need to be terminated if necessary.
