You can usually get pregnant about a week after having a painless gastroscopy. Painless gastroscopy is mainly used for checking stomach diseases, and a short-acting anesthetic is usually injected to reduce the discomfort brought by the examination, which has little effect on the human body. However, the residual anesthetics after painless gastroscopy need a process to be excreted with the body’s metabolism. Therefore, women who are preparing for pregnancy should not get pregnant until about a week after having a painless gastroscopy, so as to avoid the residual drug affecting the development of the gestational sac. After the painless gastroscopy, it is best to postpone the preparation for pregnancy and recuperate the body to avoid the effect of residual anesthesia, but also to increase the chances of successful conception. It is recommended to go to the hospital for regular medical checkups to clarify the health condition of the body. If your body meets the health standards and has the basic conditions for pregnancy, then you can incorporate pregnancy into your plan to lay the foundation for eugenics.
