Title: “Long COVID Linked to Little-Known Condition: POTS”
Introduction:
In the midst of the COVID-19 pandemic, a little-known condition called POTS, or postural orthostatic tachycardia syndrome, has gained attention due to its resemblance to long COVID. POTS is characterized by a rapid heartbeat and feelings of dizziness and fatigue upon standing, greatly impacting the quality of life for those affected. Recent research has shown that a significant portion of long COVID patients also experience symptoms of POTS, shedding light on the connection between the two conditions.
What triggers POTS?:
Multiple studies, including the latest research, have identified viral infections as the most common trigger for POTS. The COVID-19 pandemic, with millions of infections worldwide, has further exposed the similarities between POTS and long COVID. The World Health Organization estimates that 10-20% of COVID-19 patients are likely to develop long COVID, which manifests as persistent symptoms lasting three months or longer after the infection.
Findings:
The recent study revealed that nearly 80% of long COVID patients examined also had POTS. The symptoms experienced by these individuals were indistinguishable from those who developed POTS through other causes. The study sample consisted of patients who either visited a specialist cardiology clinic for POTS or were part of a long COVID support group on social media. These findings indicate that POTS may potentially explain many cases of long COVID.
Effects of POTS:
POTS is believed to result from an overactive immune response triggered by viral infections, leading to dysfunction in the autonomic nervous system. This system regulates various bodily functions, and even marginal disturbances can cause a range of symptoms, including dizziness, rapid heartbeat, breathlessness, brain fog, and exhaustion. Research has shown that people with POTS have a significantly poorer quality of life compared to individuals with chronic illnesses such as cancer or cardiovascular disease.
Challenges with Diagnosis:
Diagnosing POTS can be a lengthy and frustrating process for many patients, who often encounter skepticism from medical professionals, friends, and family. In many cases, diagnosis can take years. Lack of recognition by the medical community poses a significant challenge, as highlighted by a nurse who struggled to be taken seriously despite presenting physical symptoms. Addressing the issue of prompt diagnosis is crucial, especially with increasing numbers of long COVID cases associated with POTS.
Managing POTS:
While there is no known cure for POTS, various strategies can be employed to manage the condition once diagnosed. GPs can conduct a ten-minute standing test to aid in diagnosis, while excluding other potential causes of POTS symptoms. Lifestyle changes, such as increasing fluid and salt intake, using compression tights, and avoiding triggers like extended periods of standing or hot environments, can help improve symptoms. Medication to regulate blood pressure and heart rate may also be prescribed.
Challenges with Referral and Treatment:
Referral to specialist services for POTS can be complex and expensive, as there are limited specialized clinics in public hospitals. Access to diagnosis and treatment often depends on an individual’s financial means or their ability to navigate the healthcare system effectively. Referrals to various health professionals, including physiotherapists, psychologists, occupational therapists, or exercise physiologists experienced in managing POTS, may be beneficial for patients.
Conclusion:
The growing recognition of the connection between long COVID and POTS highlights the importance of early diagnosis and proper management of POTS symptoms. Despite the challenges in receiving proper care, patients experiencing symptoms are advised to seek assessment from their GPs. The Australian POTS Foundation website provides further information about the condition and lists healthcare professionals who are knowledgeable about POTS, offering support and resources for those affected.
