Obesity can lead to increased blood pressure, usually caused by the following factors: 1, peripheral vascular resistance; 2, the elasticity of the arterial wall; 3, and blood viscosity are related to these aspects. If the patient has excessive obesity, vascular resistance will increase, because normal people’s intima is smooth and smooth, but for obese patients will appear in the intima deposited atherosclerotic plaque, so there will be vascular sclerosis, vascular elasticity decreased, which will lead to increased blood pressure. In addition, obesity can also appear hyperlipidemia and high blood viscosity, in this case the patient will also be subject to increased resistance to blood flow, which will cause a further increase in blood pressure, so obesity has become one of the independent risk factors for hypertension.
