The most common reason for getting up with dizziness and unstable standing is the lowering of blood pressure after a change in position, and postural hypotension, which leads to a transient lack of blood supply to the brain, resulting in dizziness and unstable standing. At this point, you need to immediately hold on to surrounding objects and immediately sit down or lie down or squat down to prevent fainting and falling. The next time you get up from bed, every time you change your position, your movements should be gentle and slow to give your body enough time to adapt. If symptoms recur, it is best to monitor blood pressure to see if there are any abnormalities in blood pressure, and then go to the hospital for related tests to rule out other diseases such as cerebral infarction and Meniere’s disease.
