"They told me I had a virus," said Tori, "but I had never heard of one where you are dizzy all the time. There were a lot of times I couldn't get out of bed."
POTS is a malfunction of the autonomic nervous system, which controls the involuntary functions of the body, such as heart rate, blood pressure, digestion, breathing, blinking and urination. While it can and does affect any part of that system, the most frequent symptoms are profound fatigue, gastrointestinal issues and frequent, almost constant lightheadedness.
"It was tough for me because I was still healthy," said Nick Foles, "and I could see what she was going through. But she's amazing and we've grown closer together."
The couple spoke Saturday at the annual meeting of Dysautonomia International
, a non-profit association dedicated to POTS research, education and patient empowerment.
"POTS patients do not do well with gravity," said Dr. Satish Raj
, medical director of the autonomic investigation unit at the Libin Cardiovascular Institute of Alberta.
"Normally, when you stand up, your heart rate automatically goes up about 10 to 15 beats per minute to increase blood pressure and blood flow and then stabilizes," he explained. "In POTS, it's at least 30 beats a minute within 10 minutes; some can be as high as 60 beats per minute. The brain jumps in to shut that down and you become faint."
from Mayo Clinic shows that the quality of life in POTS patients is similar in what is seen in congestive heart failure, or chronic obstructive pulmonary disease," said Dysautonomia International co-founder and President Lauren Stiles, who is also a POTS patient.
It's estimated POTS affects
between 1 and 3 million Americans. But since so few doctors are educated on the symptoms, experts believe numbers could be much higher, both in the US and in the rest of the world. POTS support groups are found in Australia, Brazil, Canada, Egypt, France, Germany, Ireland, Israel, Japan, Mexico, the Netherlands, New Zealand and the United Kingdom.
"How many people are out there? God only knows," said University of Toledo Dr. Blair Grubb
, a cardiologist who specializes in autonomic and heart rhythm disorders. "Are there a lot of people out there never diagnosed because they are only moderately impaired?"
"I call it the most common condition you've never heard of," said Stiles, adding that the Mayo Clinic estimates 1 in 100 teens develop POTS.
The Foles are committed to
raising awareness about the disorder. Nick Foles has dedicated
a chapter in his new book, "Believe It
," to Tori and her struggles with the condition.
"One of the hardest parts was Nick was at the top of his career and our life together was just beginning," said Tori. "But mine was now at rock bottom."
Tori met Nick in college when he was the quarterback for the Arizona Wildcats and she was a setter for the university's volleyball team
. The two became good friends and began dating after graduation. When Tori was diagnosed with POTS at age 23, Nick was there to support her. They married in 2014.
