In patients with hyperglycemia, blood pressure is usually also increased because patients with hyperglycemia have abnormal glucose metabolism and abnormal lipid metabolism, thus causing changes in peripheral vascular resistance, vascular elasticity of the arterial wall, and blood viscosity of the arterial wall, among other factors. In patients with hyperglycemia, if combined with hyperlipidemia, atherosclerotic plaques will gradually form under the intima, causing vascular sclerosis, decreased elasticity and increased brittleness of the arterial wall, thus increasing blood pressure. In the long term, the instability of the plaque will increase, and the plaque will rupture and bleed, causing the narrowing of the lumen and increasing the resistance to blood flow, which will further lead to the increase of blood pressure. When blood lipids and blood glucose increase at the same time, blood viscosity will also increase, and there will be an increase in blood flow resistance, which will further lead to an increase in blood pressure.
