If a breastfeeding mother needs a CT, this test can still be done without affecting breastfeeding. Although CT has a certain amount of X-ray radiation, it is still within the body’s permissible range and does not pass through the metabolism of breast milk. It is recommended that the mother breastfeeds her baby before the CT, and then goes to the CT after the breastfeeding, and after the CT examination, for safety reasons, she can express the milk this time and then feed her baby afterwards, which may be safer and more reliable. After the CT, the mother should rest as much as possible and eat more vegetables, fruits and foods with high protein content. In addition, breastfeeding mothers must pay attention to their health and if they need medication when they are not feeling well, they must use it under the guidance of a doctor and try not to use medication that is excreted through breast milk. If you have to use drugs that are excreted through breast milk and may have some effect on the baby’s body, the mother needs to stop breastfeeding temporarily.
