POTS stands for Postural Orthostatic Tachycardia Syndrome. It is a condition in which the autonomic nervous system does not regulate properly, particularly in how the body responds to standing. The autonomic nervous system controls automatic functions such as heart rate, blood pressure, digestion, and temperature regulation.
One of the challenges with POTS is that its symptoms can appear in ways that resemble many other conditions. Healthcare providers who are not familiar with autonomic dysfunction may attribute these symptoms to anxiety or stress, other medical conditions, or, in some cases, suggest they are psychological.
This often leads to months or even years of frustration, as individuals move between specialists and receive multiple misdiagnoses before getting clear answers.
What Makes POTS Symptoms Easy to Misinterpret
POTS does not present the same way every day. Someone might wake up feeling fairly functional one morning and struggle to get out of bed the next. This inconsistency can lead people to question their own experience.
Another challenge is that the symptoms do not appear obviously connected at first. Dizziness, digestive issues, brain fog, and a rapid heart rate do not immediately suggest a single underlying cause. Without a clear understanding of autonomic dysfunction, each symptom may be evaluated in isolation rather than recognized as part of a broader pattern.
Frequently Misdiagnosed POTS Symptoms
Dizziness and Lightheadedness
Many people have felt briefly dizzy after standing up too quickly. With POTS, the dizziness is typically more intense. It can occur whenever someone stands, and it does not necessarily resolve within a few seconds.
Some individuals describe the sensation as the room spinning or feeling close to fainting. Others report that their vision darkens around the edges or that they feel detached from their surroundings. The dizziness can last for several minutes, and in some cases, it can lead to fainting.
This symptom is often attributed to dehydration, low blood sugar, or inner ear disorders. Healthcare providers may recommend increasing fluid intake or eating more consistently.
While these strategies may help reduce symptom severity, they do not address the underlying autonomic dysfunction responsible for POTS.
Rapid Heart Rate Especially When Standing
A sudden pounding heartbeat can feel alarming. You may notice it in your chest, throat, or even your ears. It can happen without any strenuous activity, simply after standing up to get a glass of water.
For individuals with POTS, this response can occur many times throughout the day. Heart rate may increase significantly with minimal movement. Someone might be sitting at a desk, stand to walk a short distance, and see their heart rate rise.
This symptom is frequently misinterpreted as anxiety or panic attacks. The sensation of a racing heart can be unsettling and may trigger secondary anxiety. However, in POTS, the elevated heart rate typically begins as a physiological response to standing rather than as a reaction to anxious thoughts.
Chronic Fatigue
Everyone experiences tiredness at times. Fatigue associated with POTS is different. It is a deep, persistent exhaustion that does not improve with rest. Someone may sleep for ten hours and still wake up feeling as though they barely slept.
This fatigue often intensifies after physical activity, even mild tasks such as walking around the block or standing to prepare a meal. The body expends significant energy attempting to regulate blood flow and heart rate, which can leave little reserve for other daily activities.
Healthcare providers may attribute this level of fatigue to depression, burnout, or poor sleep habits. Lifestyle adjustments or antidepressants are sometimes recommended. Depression can occur alongside POTS, and treating it may help overall well-being, but focusing only on depression does not resolve the underlying autonomic dysfunction contributing to the exhaustion.
Brain Fog
Brain fog in POTS goes beyond occasional forgetfulness. It can involve difficulty concentrating, trouble finding the right words, and struggling to process information that would normally feel manageable.
Many individuals describe the sensation as thinking through mud. Reading a paragraph may take significantly longer than usual. Following a conversation can require sustained effort. Remembering appointments, deadlines, or everyday tasks may become challenging.
These cognitive symptoms are often attributed to stress or feeling overwhelmed. Some people even worry about serious neurological conditions. In POTS, however, these difficulties are linked to changes in blood flow to the brain.
Shortness of Breath
Shortness of breath is another symptom that may occur with POTS. It often worsens when standing or during physical activity. A person may feel unable to take a full breath or notice that breathing requires more effort than usual.
In POTS, breathing changes are connected to autonomic dysfunction affecting multiple body systems at the same time. The same regulatory imbalance that influences heart rate and blood pressure can also alter normal breathing patterns.
Gastrointestinal Problems
Nausea is very common in POTS. Some individuals experience early satiety, feeling full after eating only a small amount. Bloating, abdominal discomfort, and changes in bowel habits can also occur.
These symptoms can resemble irritable bowel syndrome, food intolerances, or other digestive conditions. Many people undergo extensive elimination diets in an effort to identify trigger foods. While some individuals with POTS do have food sensitivities, digestive symptoms often continue regardless of dietary changes because they stem from autonomic dysfunction affecting the gastrointestinal system.
The autonomic nervous system regulates digestive motility and function. Disruption in this system can slow digestion, alter stomach emptying, and lead to a range of gastrointestinal symptoms.
Temperature Intolerance and Excessive Sweating
People with POTS often have difficulty regulating body temperature. They may become overheated and sweat heavily with minimal exertion or feel unusually cold even in warm environments. Shifts in temperature can also trigger other POTS symptoms, with heat commonly associated with symptom flare-ups.
Abnormal sweating patterns are also reported. Some individuals sweat excessively, while others sweat very little. This symptom does not often lead to evaluation of autonomic function and is frequently viewed as a personal trait or attributed to hormonal changes.
Emotional and Mental Health Symptoms That Add to Confusion
The physical symptoms of POTS can closely resemble anxiety. A racing heart, dizziness, shortness of breath, sweating, and trembling are common in both POTS and panic attacks.
The distinction lies in what triggers these symptoms. In POTS, the trigger is typically physical, such as standing up or exposure to heat. The physiological response occurs first, and any anxiety often develops afterward as a reaction to feeling unwell.
Because the symptoms overlap significantly with anxiety disorders, many individuals with POTS are labeled as anxious or told their symptoms are psychosomatic. This experience can be harmful, particularly when people begin to question the validity of their own physical symptoms.
Repeatedly being told that symptoms are “just anxiety” can contribute to anxiety or depression in addition to the existing physical condition. It can also discourage individuals from continuing to seek medical evaluation if they feel dismissed or misunderstood.

Why Proper Diagnosis Matters
Because POTS involves a wide range of symptoms across multiple body systems, it requires a provider who understands how these systems interact. A comprehensive evaluation helps ensure that symptoms are viewed collectively rather than addressed one at a time.
At our wellness clinic in Lafayette, we evaluate POTS using advanced testing aimed not only at confirming the diagnosis but also at identifying contributing factors in each individual case.
This includes assessment of autonomic function along with investigation into potential underlying influences such as viral triggers, immune dysregulation, and other factors that may be contributing to symptoms.
Conventional treatment strategies often focus on symptom management. This may include medications for specific concerns, increased salt and fluid intake, and structured exercise programs. While these approaches can reduce symptom severity, they may not fully address the underlying autonomic dysfunction.
We have worked with many patients who spent years moving between specialists, collecting diagnoses that never fully explained their symptoms, trying medications that provided little relief, and being advised to focus only on stress management.
If your symptoms align with POTS and you have not found clear answers, it may be time to seek a more comprehensive evaluation. Schedule a consultation with our team.
