High low blood pressure, also known as high diastolic blood pressure, may be due to atherosclerosis, rapid heart rate or disease, etc., and need to be based on the specific causes of the corresponding life management as well as drug treatment. 1. Atherosclerosis: when eating too much high-fat and high-cholesterol food, it will increase the blood viscosity to form plaque deposited in the blood vessel wall, so that the blood vessel wall loses its elasticity, resulting in elevated diastolic blood pressure. At this time, we need to actively engage in physical exercise and healthy diet to enhance the elasticity of the blood vessel wall, reduce blood viscosity and improve the symptoms of high blood pressure. 2. Fast heart rate: when the heart rate is too fast, it will cause the heart to shorten the contraction cycle, causing the blood in the blood vessels to increase the pressure on the blood vessel wall is too large, resulting in a significant increase in diastolic blood pressure. Normally, you can do more exercise to increase cardiopulmonary function, and if necessary, you can take some drugs under the guidance of a doctor, such as metoprolol, bisoprolol and so on. 3. Diseases: Some diseases can also cause symptoms of high blood pressure, such as nephritis, renal artery stenosis, etc., then we should consult a doctor in time to do the relevant examinations, according to the cause of the cause of the treatment, with the treatment of the disease, high blood pressure symptoms will also be improved. Elevated diastolic blood pressure can be regarded as the early manifestation of hypertension, must pay attention to the suggestion of timely medical treatment to avoid aggravation of the condition.
