Free blood pressure testing is available in Montgomery and Prince George's Counties during May.

The annual campaign aimed at early detection and treatment of high blood pressure is being conducted by public and private agencies throughout the metropolitan area.

"National statistics show that high blood every year and contributes to hundreds of thousands more," said Dr. William J. Washington Jr., acting director of public health for the District.

"One in seven adults in the U.S. has high blood pressure; and if a person is black, more than 50 years old or pregnant, the chances of having high blood pressure are even higher," he said. "When it is untreated, high blood pressure is the leading cause of strokes, heart disease and kidney disease."
