Is angiography harmful to the body?

Angiography generally does not cause significant harm to the body, but certain discomfort or minor risks may exist. Angiographic examinations typically use iodine-based or other contrast agents, allowing visualization of internal organ structure and function through X-ray or ultrasound. In most cases, this procedure is safe; however, some individuals may experience transient discomfort, such as abdominal distension, pain, or mild allergic reactions. In rare instances, complications such as contrast allergy, infection, or other adverse events may occur, although the probability is low. Doctors will evaluate the patient's health status before the examination to minimize potential risks. Pregnant women should avoid radiation-related contrast examinations to prevent harm to the fetus.

To ensure the procedure goes smoothly, it is recommended to communicate with the doctor in advance and inform them of any allergy history or other medical conditions. Before the examination, patients should follow the doctor's instructions for preparation, such as fasting or bowel cleansing. After the examination, it is important to monitor bodily reactions, and seek immediate medical attention if abnormal symptoms such as severe pain, fever, or rash occur. Maintaining a positive mindset and avoiding excessive anxiety in daily life can help alleviate discomfort associated with the examination.
