Dizziness when standing: what can be?
A study at Harvard University, published in Neurology, investigated what might be behind the dizziness that appears after lifting, and found that it can be a warning sign of a serious neurological disease and even increase the risk of early death .
Causes of dizziness when standing
There are several causes for the problem. Diabetes, dehydration, changes in medication and ear structures to treat high blood pressure are some of them.

But there are other cases where the dizziness may be caused by a gradual drop in blood pressure. It is "It suggests that the nervous system is failing to keep blood pressure while you are standing"Explains researcher Christopher Gibbons, who led the study.
This condition is called orthostatic hypotension, and is defined as a drop in blood pressure that occurs within three minutes after lifting. If it persists for longer, it becomes prolonged called orthostatic hypotension. The problem is more common among older people, 5% to 10% of people aged between 60 and 70 years.
In the study, researchers reviewed the medical records of 230 people who have undergone tests in 2002 and 2003 to identify whether their bodies were properly regulating blood pressure and heart rate. Just over these 160 participants were followed for the next 10 years.
During this period, 48 participants had prolonged orthostatic hypotension - a condition which led to the death rate of 29% - and 42 had orthostatic hypotension - group had 64% risk of death. For comparison, 9% of people in the healthy group, we had no type of orthostatic hypotension, died.
The survey showed that 35% of people who had orthostatic hypotension, 35% developed some degenerative brain disease such as Parkinson's disease or dementia.
The researchers call attention to the need for further studies, we find hypotheses for this relationship and assess more people and also ask that people do not assume to have a more severe disease if they have this kind of dizziness, since the orthostatic hypotension is not the only cause behind the vertigo.
