Normal adult systolic blood pressure is between 90-139mmHg, and diastolic pressure is between 60-89mmHg. When the systolic pressure exceeds 140mmHg and the diastolic pressure exceeds 90mmHg, this condition is medically referred to as hypertension. When the systolic pressure is below 90mmHg and the diastolic pressure is below 60mmHg, this condition is medically referred to as hypotension. Regardless of whether it is hypertension or hypotension, it often causes symptoms in patients, such as headache, dizziness, and fatigue. Therefore, whether it is hypertension or hypotension, one should visit the hospital's department of cardiology for a formal examination. The doctor will assess the situation on-site to determine if treatment is necessary and how to administer it.
