If an elderly person develops high blood pressure, it is possible to fly. However, attention should be paid to prevention and preparation in advance, such as having antihypertensive medication on hand. During the ride, if you have symptoms of discomfort, such as dizziness, panic, or increased blood pressure, you should promptly report them to the medical staff and flight attendants. Through the crew for blood pressure measurement, if the blood pressure is high, you can give your own preparation and the plane’s emergency drugs to lower blood pressure. In addition, during the journey, it is important to maintain emotional stability and not to get too excited and nervous. If the dose of blood pressure medication is not enough, or if you cannot control your blood pressure to a stable and ideal state, you can reflect this to the flight attendants, who will make adjustments to the medication according to their expertise.
