Dizzy When You Stand Up? Too Much Sodium or Too Little?

Becoming dizzy upon standing is a relatively common condition that’s associated with an increased risk of falls in older adults. A study conducted at Beth Israel Deaconess Medical Center in Boston suggests that increasing salt intake, which is considered the standard intervention to prevent what doctors call postural lightheadedness, may instead raise the risk.

Results of their study, published in The Journal of Clinical Hypertension, used previously unreported data from the DASH-Sodium trial, which looked at the effects of dietary salt on blood pressure. People in the DASH trial were asked if they experienced dizziness upon standing.

According to the Boston researchers, their data show that the idea that cutting back on salt can cause dizziness when you stand up may not be scientifically based. Their findings call into question recommendations to use more salt to treat postural lightheadedness, especially in younger people.
