What does it mean when diastolic blood pressure is high?

High diastolic pressure, also known as elevated diastolic blood pressure, generally indicates that the diastolic component of blood pressure exceeds the normal range. This may be related to several factors: 1. Unhealthy lifestyle habits: Chronic sleep deprivation and poor diet (such as high salt intake) can contribute to high diastolic pressure. 2. Genetic predisposition: Hypertension tends to run in families; individuals with immediate family members who have hypertension are at increased risk. 3. Underlying medical conditions: Abnormal kidney function, cardiovascular disorders (such as aortic stenosis or mitral stenosis), peripheral small vessel spasm or disease, and increased blood viscosity may all lead to elevated diastolic pressure. When managing high diastolic pressure, it is recommended to improve lifestyle habits—such as reducing salt intake, adopting a low-fat and low-sugar diet, and engaging in regular aerobic exercise—and, under a doctor's guidance, use appropriate medications if necessary.
