X-rays can cause physiological and biochemical changes to human germ cells, human body fluids and tissue cells, causing varying degrees of damage. Therefore, it is generally not recommended that patients undergo x-ray examination in the early stages of pregnancy. X-rays are radioactive and may cause physiological and biochemical changes to human germ cells, body fluids and tissue cells, resulting in various degrees of damage. However, a few occasional checkups in the general population usually do not affect the human body too much, so patients do not need to worry too much. Gonads, embryos and fetuses are sensitive to X-rays, and it is not recommended for patients in the early stages of pregnancy or during ovulation to avoid damage to egg cells, fertilized eggs and fetuses. During the examination, the non-examined parts should be well covered with lead protective devices. If you experience any discomfort or abnormal symptoms after the examination, you should go to the hospital for a follow-up examination.
