A blood pressure of 125/87 usually refers to a systolic blood pressure of 125 mm Hg and a diastolic blood pressure of 87 mm Hg, which is in the normal blood pressure range and is not serious. The normal blood pressure range for adults is 90-139 mm Hg systolic and 60-89 mm Hg diastolic. A blood pressure of 125/87 mm Hg is in the normal range if the person tested does not have hypertension, or 125/87 mm Hg if the person tested has hypertension that is controlled with medication. Blood pressure values are not constant throughout the day, and a single blood pressure measurement does not fully reflect an individual’s vascular functioning. If an individual has symptoms such as dizziness, headache, insomnia, or fatigue, he or she can take multiple measurements over a period of time to understand the changes in blood pressure, or he or she can undergo 24-hour ambulatory blood pressure monitoring to clarify the specific fluctuations in blood pressure. If the blood pressure value shows 125/87 mmHg, but the individual has symptoms such as dizziness and headache, the individual can go to the hospital to improve the examination, to clarify the cause of the disease, and to carry out targeted treatment.
