High Overnight Blood Pressure Linked To Increased Blood Sugar Levels

Blood Pressure and Blood Sugar

People whose blood pressure doesn't drop significantly overnight tend to have more cardiovascular problems.

Now, new research at the University of Michigan Health System and the Veterans Affairs Ann Arbor Healthcare System indicates that they also tend to have higher levels of glucose (blood sugar).

That could put these so-called "non-dippers" at greater risk for developing diabetes and other diseases, which in turn raises the risk of cardiovascular problems, researchers say.

"We found that non-dippers experienced a higher likelihood having increased fasting glucose than people whose blood pressure dips by more than 10 percent overnight," says Meredith Montero, a third-year medical student at the University of Michigan Medical School, who is presenting the research May 13 at the annual meeting of the American Geriatrics Society in Orlando.

"This means that health care providers may want to monitor these patients' glucose more closely and emphasize to them the importance of monitoring their blood pressure," Montero says.

Researchers studied 51 patients ages 60 to 80 who have high blood pressure, or hypertension. Of those, 20 were non-dippers, whose blood pressure does not drop by 10 percent at night. Most people in the general population are "dippers," but it is common for people with hypertension to be non-dippers.
