A life-changing condition called POTS, which can cause fainting, irregular heartbeats and dizziness, particularly among young women, appears to be on the rise as a result of the coronavirus pandemic.
But the condition isn't well understood, and many patients are dismissed as having anxiety, delaying diagnosis. Once diagnosed, many patients face waiting lists as long as two years to get treatment from specialists.
POTS stands for postural orthostatic tachycardia syndrome, a disorder of the autonomic nervous system, which regulates involuntary functions like heart rate, blood pressure and digestion.
"When the autonomic nervous system is not functioning properly, any or all of those things can go a little haywire," said David R. Fries, a cardiologist and POTS specialist at Rochester Regional Health.
POTS patients typically experience a marked rise in heart rate when standing and a complex combination of symptoms, including dizziness, brain fog, fainting, headache and fatigue, among many others.
There is no known cure for POTS, but physical therapy, medications and diet changes related to salt intake can sometimes help.
Experts say there is a dire shortage of medical professionals who know how to care for patients with POTS. Lauren Stiles, president and chief executive of Dysautonomia International, a nonprofit advocacy group, estimates that the number of people with POTS has at least doubled since the start of the pandemic, while the number of specialists has remained the same and waiting lists are getting longer.
"They were overwhelmed and flooded long before covid," Stiles said "We need to increase the amount of experts in this because it wasn't enough before covid, and it's certainly not enough now."
POTS symptoms are often diagnosed as anxiety
Symptoms can vary widely, and in some cases, can be debilitating.
Angelica Baez, 25, of Sacramento, got sick with covid in March 2020. Soon after, she developed unusual symptoms, including tingling hands, frequent diarrhea and either feeling extremely cold or extremely hot. But the most debilitating symptom was that she almost constantly felt dizzy. She often felt like she might pass out and had trouble walking long distances.
"My heart started going insane. I could feel it pounding in my chest," she recalled. "I literally felt like I was going to die."
Just standing up or walking across the kitchen caused her heart rate to spike to 160 beats per minute, and she frequently rushed to the E.R., worried that she was having a heart attack. She tried consulting various doctors but was dismissed because nothing seemed wrong with her heart or overall health.
"I would go to the doctor, and he just started telling me, 'No, I think you just have anxiety,'" she said. "And I was like, you know what? I have anxiety because of what's happening to me."
Baez was finally seen by a cardiologist who diagnosed POTS in early 2022.
Life has changed dramatically for Baez since developing POTS. She needs to use a wheelchair to go longer distances and a shower chair to bathe. She gets dizzy if she sits upright or stands for long periods of time. Before getting sick, she was painting and interviewing for a job as a medical secretary. She can no longer work and can only paint in short bursts.
Now, Baez is taking salt tablets and fluids and wears compression garments, which are both common interventions for POTS. She hasn't been able to find a POTS specialist in her area. She sees a cardiologist and has been trying alternative treatments like acupuncture and herbal medicine.
A two-year waiting list for POTS patients
Part of the problem in diagnosing and treating POTS patients is that many doctors aren't familiar with it and patients often see multiple doctors before finally getting diagnosed. One study of more than 4,800 POTS patients found that most didn't get diagnosed until a year or more after first seeing a doctor, and the average diagnostic delay was nearly five years.
