Is fasting required for a carotid ultrasound?

Fasting is not required for a carotid ultrasound because this specific imaging procedure is designed to evaluate the blood flow and structure of the carotid arteries, which supply blood to the brain. The test uses sound waves to create images and does not involve any tests that would necessitate fasting, such as those that assess lipid levels or metabolic functions.

Patients can typically eat and drink normally before the ultrasound without affecting the results. This makes preparing for the procedure more convenient for patients, as they do not have to abstain from food or beverages beforehand. While there may be scenarios where specific instructions are given based on individual health factors or additional tests, fasting is generally not a standard requirement for carotid ultrasound procedures.
