SAN ANTONIO -

Nicole Page is a kidney disease survivor.

A year ago doctors said one of her kidneys was failing and the other was on its way.

Fortunately, she got a kidney donation from her brother. Thanks to a new lease on life, she's changed the way she eats and lives.

"I go to the gym and I watch what I eat," said Page.

This weekend, the American Kidney Fund will host its annual Kidney Action Day at the AT&T Center.

It's estimated that as many as 31 million people in the US are living with chronic kidney disease and don't even know it.

A local kidney specialist said kidney disease typically has no symptoms, but certain people are at risk.

"Every age group is at the high risk especially people who are overweight and high blood pressure," said Dr. Shweta Bansal a nephrologist.

Earlier this year, Page shared her survival story in Washington, D.C., and other kidney awareness events across the country.

She hopes people will take the time to get checked out for kidney disease if they're at risk.

"Go to your doctor and make sure your high blood pressure and your diabetes and your sugar is doing pretty well, otherwise it may affect your kidneys and other organs too,” said Page.

The American Kidney Fund Walk is October 6, 9:00 a.m. will be the registration, and 10:00 a.m. will be the walk. The day will be filled with free health screenings and information by local kidney specialists.
