Average blood pressure readings per age

Quality of life is greatly improved when healthy lifestyle is maintained. In the U.S., approximately 50 million people suffer from high blood pressure. Left untreated, the condition can lead to kidney failure, heart disease, stroke or death. The importance of monitoring blood pressure levels is critical.


Blood pressure is the force of blood on blood vessel walls as blood circulates through veins, arteries and capillaries. The calculations are represented with two measured numbers; systolic pressure and diastolic pressure. In written format, the systolic number appears first.

Blood Pressure Readings

There are three ranges for blood pressure that identify health risks. Normal blood pressure in an adult is approximately 120/80, high blood pressure known as hypertension is 140/90 or higher, and any combination below 120/80 is considered low blood pressure known as hypotension. Blood pressure readings can vary depending on emotional state, posture, activity or temperature. Readings from an average of two separate measurements should be considered to account for these variants.

Blood pressure ranges by age

High blood pressure symptoms can include dizziness, bloody nose or headaches. These symptoms may not appear pronounced for years until high blood pressure is in its advanced stages and possibly life threatening. Consult a physician for regular assessments of blood pressure and any symptoms that might be related to blood pressure status.


Blood pressure can be affected by weight, diet, exercise and medication. Diets that incorporate low sodium or no sodium choices, vegetables, low fat options and lean or meatless options can help in controlling high blood pressure. Half an hour of exercise daily can lower blood pressure. Consult a physician for a program that monitors or reduces high blood pressure levels.
