Poorly smooth intima-media of the carotid artery is commonly described during carotid ultrasound and is usually found during physical examination, often without any symptoms in the patient. This condition is actually an early stage of atherosclerosis, which is a normal aging process and generally does not require treatment or stress if it appears at a later age. However, this condition reminds us to pay attention to the further development of atherosclerosis, and the causative factors of atherosclerosis including high blood pressure, high blood sugar, high blood fat, smoking and obesity should be strictly controlled. A healthy diet should be done in normal times, and it is recommended to refer to the structure as well as the composition of the Mediterranean diet under the premise of total calorie determination, and to actively engage in physical exercise, which can slow down the process of atherosclerosis to the slowest.
