Thickening of the intima-media of the right carotid artery is usually an early manifestation of carotid atherosclerosis, which can usually be due to hyperlipidemia, hypertension, diabetes mellitus, and other diseases. Carotid intima-media thickening is usually the term used for ultrasound diagnosis. Under normal circumstances, the thickness of the carotid artery intima-media is less than 1mm, when the intima-media is greater than 1mm, it can be diagnosed as intima-media thickening, which is the early stage of carotid atherosclerosis, and when the thickness of the intima-media is greater than 1.2mm, it is the formation of arterial plaques. Carotid atherosclerosis is often closely related to hyperlipidemia, hypertension, diabetes, etc. These diseases can cause chronic damage to blood vessels. These diseases can lead to chronic damage of blood vessels and decrease of blood vessel elasticity, which in turn triggers atherosclerosis. If carotid artery intima-media thickening is detected, it should be consulted as soon as possible and treated under the guidance of a doctor. In daily life, we should pay attention to adjusting the diet to a light diet, and eat less high-sugar and high-fat food.
