Is fasting necessary for abdominal aortic aneurysm examination?

Abdominal aortic aneurysm examinations usually require patients to fast. This is to ensure that the examination results are more accurate and to reduce the possibility of discomfort during the examination, such as increased gastrointestinal activity after eating, which affects the clarity of the imaging.

Abdominal aortic aneurysm is a serious health problem. It refers to the aorta in the abdominal cavity that expands due to its thin wall, forming a tumor, similar to an over-inflated balloon that may burst at any time. Since the aorta is the largest artery in the human body and is responsible for transporting a large amount of blood, once it ruptures, it may be life-threatening. Accurate examination and timely diagnosis are essential to avoid serious consequences.

Ultrasound and CT scans are commonly used methods for examining abdominal aortic aneurysms. Fasting can reduce the interference of intestinal substances, making ultrasound or CT images clearer and allowing doctors to observe the condition of the aneurysm more accurately. If the patient has already eaten, the gastrointestinal gas and food may affect the visualization of the target area by the examination instrument. Fasting examinations usually require stopping eating the night before and maintaining an empty stomach in the early morning, following the instructions of the doctor or examination center.

When undergoing the examination, in addition to keeping an empty stomach, patients should also pay attention to relaxing and choosing comfortable clothes for easy operation. If you know that you have abdominal aortic aneurysm or related risks, you should consult a professional doctor to obtain personalized health advice to ensure that the examination and daily health management are on a safe and effective track.
