POTS stands for Postural Orthostatic Tachycardia Syndrome. It is a form of dysautonomia, meaning a condition that affects how the autonomic nervous system regulates things like heart rate, blood pressure, and circulation.

The hallmark of POTS is when a person goes from lying down to standing, their heart rate rises significantly, and they develop symptoms like dizziness, lightheadedness, palpitations, fatigue, or brain fog.

For many people in withdrawal, this topic comes up because not only can some people develop POTS, but the symptoms can look very similar, leading to false diagnosis and cardiophobia.

That overlap can create a lot of fear and confusion, which I hope to help clear up in this lesson.

What POTS Is:

POTS is a postural condition, meaning symptoms are tied to position. When you stand, gravity pulls blood into your lower body. Normally, your nervous system adjusts by tightening blood vessels and maintaining steady circulation to the brain.

In POTS, this adjustment is less effective, as blood may accumulate in the lower body, and circulation to the brain may decrease slightly. The body responds by raising the heart rate to compensate.

This can lead to:

• Dizziness or lightheadedness when standing

• Rapid heartbeat (especially upright)

• Fatigue and weakness

• Brain fog

• Nausea

• Exercise intolerance

• Feeling better when lying down

POTS is not just “anxiety” or “being out of shape.” It is a real autonomic pattern involving circulation and nervous system regulation. Additionally, POTS doesn't usually disappear gradually, day-by-day, but in fluctuations.

A person may feel more intense symptoms of POTS early into withdrawal, and as they stabilize and become more regulated, have good and bad days.

They may have periods where symptoms are barely noticeable, followed by flare-ups triggered by stress, illness, poor sleep, dehydration, or overexertion. They may have times where they feel totally normal, then experience some return.

The important thing to know about POTS is that it's not permanent, and typically resolves with recovery.

True POTS (Primary Dysautonomia)

So far, we've been mostly exploring traditional POTS through the lens of primary dysautonomia, which is different from benzo-induced POTS and persistent autonomic conditioning (limbic-learned pattern). But first, it's important to note that, as a withdrawal symptom, POTS is one of the most commonly misdiagnosed or misattributed conditions.

Countless people on benzo forums talk about having POTS, usually self-diagnosed, and rarely, actually True POTS. That's not to say they're not having real POTS-like symptoms. They usually are. But there's a different causation for what's happening.

Traditional (or True) POTS is more of a dysautonomia issue, characterized by a consistent increase in heart rate when standing, a clear postural pattern, and is confirmed through testing. These symptoms generally persist outside of the withdrawal context.

When this occurs, it's usually associated with an underlying autonomic dysfunction, post-viral syndromes, connective tissue disorders, or other physiological contributors.

Withdrawal-Associated Orthostatic Dysregulation

As I said, POTS in withdrawal is usually a bit different in terms of how it appears and why. What many call POTS, in withdrawal, is usually withdrawal-associated orthostatic dysregulation. This feels very similar to True POTS, but usually is a result of a sensitized, hyperactive nervous system that has currently become unstable in regulating heart rate and circulation.

Remember, withdrawal creates functional issues, not so much structural ones. Dysregulation occurs when different parts of the brain have trouble communicating with one another in a harmonious manner.

The limbic brain helps regulate powerful survival autonomic functions, such as respiratory, heart rate, and blood pressure. Communication between these functions can become temporarily impaired or dysregulated.

Further, withdrawal is essentially, largely, and GABA/Glutamate imbalance. It's an issue between gas/brake systems in the body, which also stems outside the brain, anywhere GABA/Glutamate can be found.

Withdrawal-associated orthostatic dysregulation can create:

• dizziness when standing

• heart racing

• palpitations

• weakness

• fatigue

• lightheadedness

• exercise intolerance

Persistent Autonomic Conditioning (Bear Learned Pattern)

One of the most overlooked phenomena in withdrawal is the power of the limbic brain once it has learned certain reactions. This can be so dynamic that people simply cannot believe it's coming from a conditioned response, when it is.

Withdrawal isn't just about imbalance, sensitization, receptor injury, or dysregulation… there's an anxiety part of our survival brain involved, and it can build a kind of responsive circuitry around withdrawal and symptoms, around dysautonomia.

This makes it challenging to differentiate one thing from the next!

Persistent autonomic conditioning happens over time, where the limbic brain becomes conditioned to react strongly to standing, associating upright posture with danger. It usually begins with a jolt of anxiety related to dizziness or a change in heart rate or blood pressure upon standing.

The individual feels that jolt of fear, and the limbic brain (Bear) takes note, and soon begins replicating the experience. What may have begun as mild POTS or Withdrawal-Associated Orthostatic Dysregulation becomes a conditioned, learned response from the limbic brain that can then go on for much longer periods of time.

Why This Distinction Matters

Because each pattern has a different implication:

• True POTS → requires medical management + support

• Withdrawal dysregulation → improves with nervous system healing

• Conditioned patterns → improve with retraining + gradual exposure + regulation

Without this distinction, everything gets lumped into:

👉 “I have permanent damage!”

And that’s where fear explodes. 😱

What POTS Is Not

Now that we've looked at what POTS is and how other similar conditions can mirror POTS in withdrawal, let's differentiate what it isn't for more clarity.

POTS is not:

• Anxiety-induced BP or cardiac changes

• Occasional dizziness

• A racing heart without a clear postural pattern

• Automatically caused by withdrawal

• Heart palpitations

• Exercise intolerance

• Diagnosed based on symptoms alone

A key point to remember is that POTS has a pattern.

Symptoms are reliably consistent and worsen when upright and improve when lying down.

Without that pattern, it is likely something else.

How POTS Is Diagnosed

POTS is not diagnosed through guesswork.

Typically, it involves measuring your heart rate both while lying down and standing up. Sometimes, a structured standing test or tilt-table test is done. It's also important to rule out other possible causes like dehydration, anemia, thyroid problems, high blood pressure, or side effects from medications.

This is why self-diagnosing based on symptoms alone can be misleading, especially if you have health anxiety!

Supporting the System (Whether It’s POTS or Not)

Regardless of the label, the nervous system benefits from stability, desensitization training, physical conditioning, and nervous system regulation. If you're in the school and working on our problem, you might be surprised to see POTS or POTS-like issues begin to fade away as you become more regulated, stable, and active.

Many of the same strategies support both withdrawal and orthostatic symptoms:

• Adequate hydration

• Sufficient nutrition

• Appropriate salt intake (when medically appropriate)

• Gradual, gentle movement and reconditioning

• Avoiding long periods of inactivity

• Reducing overstimulation and panic loops

• Building consistent daily rhythm

• Desensitization training

• nervous system regulation

These are not quick fixes, but they are stabilizers that help with time and work.

Common Myths

“POTS is just anxiety.”

No. It is an autonomic pattern, though symptoms can overlap with anxiety.

“If my heart races, I have POTS.”

Not necessarily. Many conditions can cause this.

“Withdrawal causes POTS.”

Not clearly established. Withdrawal can mimic or worsen similar symptoms.

“I’ll never recover if I have this.”

Not true. Most people fully recover over time with proper support.

💡 The Bottom Line

POTS is a condition that affects how your body responds when you stand. Sometimes, withdrawal can cause a temporary state that might seem similar. Remember, not every dizzy spell or racing heartbeat is caused by POTS, and not every symptom needs to be permanently labeled. More likely, in withdrawal, symptoms are related to withdrawal itself.

The important thing is not to panic or try to self-diagnose. Instead, focus on understanding your patterns, supporting your nervous system, and seeking proper evaluation when needed. Your body isn’t failing you. It's simply recalibrating. With time, the right support, and a bit of patience, your system can find its way back to balance again.
