A blood pressure of 110/54mmHg systolic is normal and diastolic is slightly below the normal range. Currently, the clinical standard for normal blood pressure is a systolic blood pressure of 90 to 139 mm Hg and a diastolic blood pressure of 60 to 89 mm Hg. When either the systolic or diastolic blood pressure is above this range, it is considered high blood pressure, and when it is below, it is considered too low. Hypertension may be primary or secondary. The cause of primary hypertension is unknown, while diseases that may cause secondary hypertension include renal parenchymal disease, renal vascular stenosis, pheochromocytoma, and primary aldosteronism. Hypotension can be caused by excessive loss of blood and fluid, such as gastrointestinal bleeding, vomiting, diarrhea, profuse sweating without timely rehydration, etc. It can also be seen in cardiac diseases, such as congenital heart disease, chronic heart failure. Therefore, when the blood pressure is not within the normal range, it is necessary to go to the hospital for a comprehensive examination to determine the cause of the disease, and control the blood pressure at the same time for the cause of the treatment.
