Low blood pressure in the morning may be determined by the type of blood pressure fluctuation, which includes four types, such as arytenoid, inverse arytenoid, super arytenoid and non arytenoid blood pressure. Low blood pressure in the morning in patients may be due to inverse arytenoid blood pressure, which can occur in normotensive individuals as well as in those with hypertension, and ambulatory monitoring of blood pressure for 24 hours is recommended. In addition, low blood pressure in the morning may also be due to the patient taking additional antihypertensive medication in the evening, and the blood pressure remains low the next morning, so it is important to identify the type of blood pressure fluctuation and adjust it accordingly. Arytenoid blood pressure means that the patient’s blood pressure is high during the day, low at night, and drops to the lowest level in the early morning, while inverse arytenoid blood pressure patients have low blood pressure during the day and high blood pressure at night.
