Why Grocery Stores Can Make People With hEDS and POTS Feel "Drunk"

You walk into a grocery store feeling relatively okay. Within a few aisles, the lights feel too bright. The shelves seem to move as you walk past them. Your eyes struggle to focus, your body feels like it is swaying, and you suddenly find yourself gripping the shopping cart just to feel steady.

Some people describe the sensation as feeling drunk, walking on a boat, being pulled sideways, or feeling strangely disconnected from their surroundings.

For people with hypermobile Ehlers-Danlos syndrome (hEDS), hypermobility spectrum disorders (HSD), postural orthostatic tachycardia syndrome (POTS), migraine, or vestibular disorders, grocery store dizziness is more than a reaction to a busy environment. It reflects how the brain integrates visual, vestibular, and proprioceptive information under real-world demand, and what happens

when one or more of those systems is already working harder than usual.

One potential contributor is visually induced dizziness, sometimes informally called supermarket syndrome. Understanding why it happens requires understanding how the brain keeps us upright in the first place.

Why Do Grocery Stores Make Some People Feel Dizzy or "Drunk"?

Grocery stores are unusually demanding environments for the human balance system.

A single aisle contains hundreds of products in your peripheral vision, repeating shelf patterns, people walking in different directions, moving carts, bright overhead lighting, patterned flooring, quick changes in visual focus, repeated head turns, reaching, bending, stopping, starting, and navigating around obstacles.

Your visual system may be telling your brain that enormous amounts of movement are occurring even though your actual body movement is relatively small.

For someone whose sensory systems are already working harder to maintain balance, that environment can become overwhelming very quickly. The result is often dizziness, nausea, disorientation, or a sense of unreality that can feel surprisingly intense given that the person is simply walking down an aisle.

How Vision, the Vestibular System, and Proprioception Control Balance

Balance is not controlled by one organ or one sensory system. Your brain constantly integrates information from three major sources.

Vision tells you where you are relative to the environment and provides information about movement around you. The vestibular system, located in the inner ear, detects movement and acceleration of the head and helps determine your orientation relative to gravity. Proprioception provides information from muscles, joints, tendons, and other tissues about where your body is positioned and how it is moving.

Your central nervous system continuously compares these signals and adjusts muscle activity, eye movements, and postural control accordingly. Most of the time, this process happens without conscious thought.

When these signals agree, balance is maintained efficiently. When they conflict, or when one source provides less reliable information, the system has to work harder to reconcile them. A visually complex environment can amplify that challenge considerably.

What Is Visually Induced Dizziness or "Supermarket Syndrome"?

The Vestibular Disorders Association describes visually induced dizziness as symptoms provoked by visually complex environments or large areas of visual movement. Grocery store aisles are a classic example.

Importantly, visually induced dizziness does not necessarily feel like classic spinning vertigo.

People may instead report:

• Feeling like they are walking on a boat

• Swaying or floating

• Feeling pulled to one side

• Nausea

• Difficulty focusing their eyes

• Disorientation

• Lightheadedness

• Feeling as though the floor or shelves are moving

• Suddenly needing to grab something for stability

Some people describe the sensation as feeling intoxicated even though they are completely alert.

One proposed mechanism is visual dependency. When vestibular or proprioceptive information is less reliable, the nervous system may place greater weight on vision for spatial orientation. In a visually quiet room, that strategy may work reasonably well. In a store filled with moving people, repeating patterns, shelves, lights, and peripheral visual stimulation, relying heavily on vision can become problematic. The visual system is suddenly providing an overwhelming amount of information.

How Hypermobility and hEDS Can Affect Balance and Proprioception

This does not mean that everyone with hEDS or HSD will develop visually induced dizziness. However, proprioceptive differences have been documented in people with Ehlers-Danlos syndrome and symptomatic hypermobility, and balance problems are a commonly reported feature of hEDS in clinical practice.

Studies have identified reduced precision in determining joint or limb position in some people with EDS, and proprioceptive impairment is recognized as an important consideration in hypermobility rehabilitation.

Proprioception essentially helps answer the question: where is my body without having to look at it? The Ehlers-Danlos Society's physical therapy guidance recognizes proprioceptive training as an important component of rehabilitation for hEDS and HSD.

If proprioceptive information is less precise, the nervous system may have to work harder to determine body position and control movement. That can contribute to compensatory strategies such as watching the feet while walking, excessive muscle tension, gripping the floor with the toes, stiffening the body, or relying heavily on visual information.

Then place that person inside a Costco, an airport, or a brightly lit grocery store. The nervous system is being asked to use vision more heavily at the exact moment the visual environment becomes considerably more complicated. That combination may increase the challenge of maintaining orientation and postural control.

How POTS Can Make Grocery Shopping More Difficult

Now add POTS or another form of orthostatic intolerance.

POTS is a disorder of autonomic regulation characterized by symptoms that occur with upright posture along with an excessive increase in heart rate during standing. In some patients, blood pooling in the lower extremities when upright reduces venous return and contributes to symptoms including lightheadedness, fatigue, nausea, brain fog, blurred vision, palpitations, headache, and exercise intolerance.

Shopping concentrates several common POTS stressors: prolonged upright posture, repeated position changes from bending to standing, static standing while reading labels or waiting in line, cognitive load, and often a warm environment.

Johns Hopkins Medicine specifically notes that POTS symptoms may worsen during situations involving significant standing, including shopping.

This means someone may simultaneously experience orthostatic symptoms and visual motion sensitivity at the same time.

The resulting sensation can be surprisingly intense. And while anxiety can understandably develop when someone repeatedly feels unsteady in public, that does not mean the underlying physical symptoms are simply caused by anxiety.

Why Does Holding a Shopping Cart Help With Dizziness?

Many patients notice something interesting: they feel significantly better if they are holding onto the cart.

That observation can provide useful clinical information, although it does not diagnose a particular condition.

A cart may provide several things simultaneously. It offers additional mechanical support and may reduce some of the postural-control demands required to walk independently. Contact through the hands also provides additional somatosensory information about the body's position relative to the environment.

The cart can also act as a stable visual reference directly in front of the person. Instead of the nervous system trying to orient itself against thousands of moving visual objects, it has a relatively stable reference point.

For someone with orthostatic intolerance, leaning partially through the arms may also change the physical demands of standing and walking.

The fact that a cart helps is therefore worth mentioning during an assessment. But it should not be treated as a diagnostic test.

Could Grocery Store Dizziness Be PPPD or Something Else?

Persistent symptoms triggered by visual environments can also occur with persistent postural-perceptual dizziness (PPPD).

PPPD is a recognized chronic vestibular disorder characterized by dizziness, unsteadiness, or non-spinning vertigo that is present on most days for at least three months and worsens with upright posture, movement, and exposure to complex or moving visual stimuli. The Barany Society diagnostic criteria for PPPD provide further detail.

However, having difficulty in a grocery store does not automatically mean someone has PPPD. Similar symptoms can occur with vestibular migraine, peripheral vestibular disorders, autonomic dysfunction, medication effects, visual problems, neurologic disorders, and other conditions.

That is why assessment matters.

How Physical Therapy Can Help With Grocery Store Dizziness

For the appropriate patient, physical therapy can evaluate much more than strength.

A comprehensive examination may assess static and dynamic balance, gait, proprioception, eye-head coordination, vestibulo-ocular function, cervical contributions, sensory dependence, movement tolerance, and the patient's cardiovascular response to upright activity.

Treatment should be individualized to the underlying problem.

When visually induced dizziness is present, vestibular rehabilitation may include carefully dosed balance activities, gaze-stability work, optokinetic stimulation, and gradual habituation to visually complex environments.

For someone with hEDS or HSD, physical therapy for hypermobility may also emphasize joint control, strength, proprioceptive training, efficient movement strategies, and reducing unnecessary muscular compensation.

For a patient with POTS, POTS rehabilitation may need to account for orthostatic tolerance, fatigue, temperature, hydration strategies prescribed by the medical team, and gradual progression of upright activity.

Importantly, the answer is rarely to place someone in the busiest grocery store possible and tell them to get used to it. Exposure needs to be appropriately graded. Too much sensory or physiologic demand too quickly can significantly aggravate symptoms.

When Dizziness Requires Medical Evaluation

If grocery stores, malls, airports, or big-box stores consistently make you dizzy, nauseated, disoriented, or unsteady, the environment itself may be revealing something about how your nervous system is processing movement, visual information, proprioception, and upright posture.

That pattern deserves to be taken seriously. It also deserves an appropriate differential diagnosis.

New, severe, rapidly worsening, or unexplained dizziness, particularly when accompanied by new weakness, difficulty speaking, fainting, significant vision changes, severe headache, chest pain, or other neurologic symptoms, requires medical evaluation rather than assuming it is related to hypermobility or POTS.

When Shopping Makes You Feel Sick, Pay Attention to the Pattern

Sometimes the question is not simply: are you dizzy?

A more useful question may be: what happens to your body when you walk down aisle three?

Because the answer can reveal quite a bit about how the visual, vestibular, proprioceptive, autonomic, and postural-control systems are working together.

If grocery stores, busy environments, or visual motion consistently trigger symptoms, talk to one of our hEDS and POTS-informed specialists - the first conversation is free.

Frequently Asked Questions

Why do grocery stores make me feel dizzy?

Grocery stores place high demands on the brain's balance system by combining moving people, repeating shelf patterns, bright lights, and peripheral visual stimulation. When the visual, vestibular, and proprioceptive systems are not integrating efficiently, or when upright tolerance is reduced due to POTS or dysautonomia, this environment can trigger dizziness, disorientation, or nausea.

What is supermarket syndrome?

Supermarket syndrome is an informal term for dizziness, disorientation, or unsteadiness triggered by visually complex environments such as grocery store aisles. It is more formally described as visually induced dizziness. The Vestibular Disorders Association recognizes it as a pattern associated with visual motion sensitivity and visual dependency.

Why do I feel drunk when walking through a grocery store?

The sensation of feeling drunk or walking on a boat in a grocery store often reflects difficulty integrating the large amount of visual movement information with vestibular and proprioceptive signals. The nervous system may struggle to reconcile what it is seeing with what it is feeling from the body, producing a sense of disorientation or unreality.

Can POTS cause dizziness while shopping?

Yes. Shopping involves prolonged upright activity, frequent position changes, and sometimes warm environments, all of which are common POTS stressors. Someone with POTS may experience lightheadedness, fatigue, brain fog, nausea, or palpitations during grocery shopping, sometimes alongside visual motion sensitivity.

Can hEDS affect balance and proprioception?

Proprioceptive differences have been documented in some people with hypermobile EDS and symptomatic hypermobility. Reduced precision in joint-position awareness may require the nervous system to rely more heavily on visual information for balance, which can become problematic in visually complex environments.

Why does holding a shopping cart make me feel steadier?

A shopping cart provides additional mechanical support, somatosensory input through hand contact, and a stable visual reference point directly in front of the body. Together, these may reduce the balance system's workload and help the nervous system orient itself more reliably in a busy environment.

What is visually induced dizziness?

Visually induced dizziness refers to symptoms such as dizziness, nausea, unsteadiness, or disorientation triggered or aggravated by visually complex or moving environments. It can occur when the nervous system places excessive reliance on vision for spatial orientation and then becomes overwhelmed by visual motion stimulation.

Could grocery store dizziness be PPPD?

It is possible. PPPD is a chronic vestibular disorder characterized by dizziness or unsteadiness that worsens in visually complex or moving environments. However, grocery store dizziness can also result from vestibular migraine, peripheral vestibular disorders, POTS, proprioceptive differences, medication effects, and other conditions. A clinical assessment is the best way to identify the contributing factors.

Can physical therapy help with visually induced dizziness?

For appropriate patients, vestibular rehabilitation can include balance training, gaze-stability exercises, optokinetic stimulation, and gradual graded exposure to visually complex environments. For people with hEDS or POTS, treatment may also address proprioception, joint stability, and orthostatic tolerance as contributing factors.

Why do bright lights and moving shelves make my symptoms worse?

Bright lighting, repeating patterns, and moving objects are particularly challenging because they create the impression of large-scale environmental movement even when the body is relatively still. This mismatch between what the visual system is reporting and what the vestibular and proprioceptive systems are sensing is a core driver of visually induced dizziness.
