Public interest in postural orthostatic tachycardia syndrome in the United Kingdom, 2004-2026: a Google Trends infodemiology study
This Google Trends infodemiology study reveals that public search interest in Postural Orthostatic Tachycardia Syndrome (POTS) in the United Kingdom experienced a sharp, sustained increase following the onset of the COVID-19 pandemic, with a notable shift toward diagnostic and self-assessment queries that suggests growing public awareness and self-investigation rather than a direct reflection of disease incidence.

Imagine a condition where simply standing up causes the heart to race, leaving a person dizzy, exhausted, and unable to function normally. This is postural orthostatic tachycardia syndrome, often called POTS. For years, people suffering from these symptoms faced a long, confusing journey to get a diagnosis, often being told their problems were not real or were caused by something else. The medical definition is specific: when an adult stands up, their heart rate must jump by at least thirty beats per minute and stay high, while their blood pressure remains stable. Yet, knowing the definition is different from knowing how many people are actually looking for answers. In recent years, the internet has become a primary place where people go to understand their bodies, searching for terms like "heart rate," "symptoms," and "tests." This shift in behavior offers a unique window into public concern, not just for a single disease, but for how society understands health itself.
A team of researchers in the United Kingdom decided to track this digital curiosity over more than two decades. They did not look at hospital records or patient surveys, which can be slow to change. Instead, they examined the public's search history on Google. By analyzing how often people in the UK typed "Pots syndrome" into the search bar between 2004 and mid-2026, they could map the rise of public attention with a precision that traditional methods cannot match. The study, which focused on health-related searches to avoid confusion with gardening pots or cookware, revealed a story of gradual awakening followed by a sharp, lasting surge.
For the first decade of the study, interest in POTS was barely visible. From 2004 to 2008, the search volume was so low it was often unrecorded. By the time the researchers reached the period from 2015 to 2019, interest had grown, but it remained modest. Then, the world changed. When the pandemic began in March 2020, the pattern of searching shifted dramatically. The data showed an immediate and significant jump in interest right at that moment. This spike was not a fleeting moment of news coverage; the high level of interest did not fade away. Instead, it settled at a new, much higher level. By the years 2022 and 2023, the average number of people searching for the condition was nearly three and a half times higher than it had been in the years before the pandemic. Even as the peak of the search volume passed in late 2022, the numbers remained stubbornly high, staying nearly three times above the pre-pandemic baseline through July 2026.
The researchers also looked at what people were actually typing to understand the nature of this new interest. They found that people were not just looking for the name of the condition; they were looking for ways to check themselves. Searches for specific phrases like "POTS symptoms," "POTS test," and "POTS heart rate" grew even faster than the general term. This suggests a population that is actively trying to measure their own health, perhaps using the heart-rate monitors found on everyday watches and phones. The study compared this growth to other heart conditions, such as fainting spells or irregular heartbeats, and found that the rise in interest for POTS was much steeper than for these other, more established diagnoses.
However, the authors are careful to state what this data cannot tell us. A search for a symptom does not prove that a person has the disease, nor does it prove that the disease has become more common in the population. The study explicitly rules out the idea that the internet alone created the condition, or that the rise in searches is simply a result of social media trends. Instead, the data points to a complex mix of factors: a possible increase in genuine illness following viral infections, a long-overdue recognition of a condition that was previously missed by doctors, and a new ability for patients to measure their own bodies. The researchers describe this as a change in attention, where the public is now looking for answers in a way they did not before.
The findings suggest that the way people understand and seek help for POTS has fundamentally changed. The sharp rise in searches for diagnostic terms indicates that many people are now in a phase of self-investigation, trying to match their own experiences with medical criteria. While this increased awareness could help more people get the care they need, it also brings a challenge: the risk of people attributing normal, temporary changes in their heart rate to a serious syndrome. The study concludes that while the internet has illuminated a dark corner of public health, the next step is to connect this digital curiosity with real-world medical outcomes. We now know that the public is watching, searching, and measuring, but understanding whether this leads to better health or confusion requires looking beyond the search bar to the people behind the screens.
