CINCINNATI -- Many people say the latest hikes in gas prices are making them sick.

Video: Pump Prices Raise Blood Pressure

They may be right, at least a little.

Cincinnati television station WLWT took paramedic Kevin Uhl to run an admittedly unscientific experiment on drivers.

Uhl measured drivers' blood pressure before and after they filled up their gas tanks and saw the cost.

"I drove from downtown to here and it cost $10. I'm on empty again," Lee Gillespie said as she filled up.

Her blood pressure was 152 over 60 before she filled up. After? 168 over 70 –- a jump of more than 10 points.

Liz Howard didn't do much better.

"I'm definitely not feeling good about it. As I was pulling up to the gas station and saw how much it was, I definitely got in a bad mood," she said.

Her blood pressure was up eight points after she was done filling up.

Dr. Dain Wahl said that increases in blood pressure can lead to headaches, chest pain, change in vision or, in extreme circumstances, a stroke or heart attack.

Wahl said that most drivers' blood pressure will return to normal a little while after they fill up.

"Try and keep your cool when you're pumping your gas, and hopefully the gas prices will come down, too," he said.

Or, you can be like Mike Rusconi. His blood pressure didn't budge during the fill up. He said he's become used to the price roller coaster.

"People know prices are high. Its not a shock to anybody," he said.
