Many people experience dizziness when suddenly standing up. Though it seems concerning, you actually have nothing to worry about, according to a cardiologist.
“Blood vessels in the upper part of the body tighten when standing, so that blood pressure remains stable when we stand up," interventional cardiologist Nadia Sutton said as quoted by kompas.com.
However, orthostatic hypotension, which is the decrease in blood pressure in the upper part of the body, sometimes occurs when standing up. While it causes dizziness, Sutton explained, this was only a short effect.
Once the blood vessels adjusted to standing up, the symptoms of dizziness would disappear, she said.
Physician Nesochi Okeke-Igbokwe added that for some people, recurrent orthostatic hypotension could be related to baroreceptor dysfunction. Baroreceptors are the receptors that regulate sudden changes in blood pressure.

She also mentioned that some people were generally more susceptible to this type of dizziness. Sitting down for a while before standing up allows the body to adjust to gravity, thus alleviating the sensation of dizziness.
Though occasional orthostatic hypotension is harmless, prolonged and repetitive symptoms could lead to fainting, repeated falls and even stroke. It is advised that you consult with a doctor to determine the cause. (iru/kes)
