In a quiet state, normal blood pressure values for 65 to 75 year olds are the same as those of the general population, i.e., systolic blood pressure of 90 to 139 mmHg and diastolic blood pressure of 60 to 89 mmHg. Blood pressure is the lateral pressure on the walls of blood vessels as the blood flows through them. It can be measured by devices such as electronic sphygmomanometers and mercury column sphygmomanometers. Blood pressure pushes blood through the blood vessels and spreads it throughout the body. Therefore, when the blood pressure is low at the age of 65 to 75, it may lead to insufficient blood supply to the heart, insufficient blood supply to the brain, and symptoms such as dizziness, fatigue, and panic, etc. Elevated blood pressure may induce hypertensive heart disease, cerebral hemorrhage, cerebral infarction, hypertensive nephropathy, etc., so it is important to keep the blood pressure normal. If you are 65 to 75 years old and have abnormal blood pressure, you need to go to the hospital for further examination of blood lipids, electrocardiogram, kidney function and other programs to find out the cause of the problem, and then under the guidance of the doctor to treat the problem.
