Understanding POTS and Poor Proprioception: Causes, Symptoms, and Treatments

Standing up should be simple. For people with POTS, it can feel like asking the body to solve a problem it no longer handles automatically.

Postural Orthostatic Tachycardia Syndrome, or POTS, is a form of dysautonomia. That means the autonomic nervous system, which manages heart rate, blood pressure, digestion, sweating, and temperature control, does not regulate those functions as smoothly as it should. When a person with POTS moves upright, the heart rate rises more than expected, often with dizziness, weakness, brain fog, or a sense of being unsteady.

Proprioception adds another layer. It is the body’s ability to sense position and movement without looking. When proprioception is affected, a person may feel clumsy, off balance, or disconnected from where their body is in space.

POTS symptoms often appear during ordinary position changes.

What happens in the body with POTS

In a typical body, standing triggers fast adjustments. Blood vessels tighten slightly, muscles in the legs help push blood upward, and the heart rate changes just enough to keep blood flowing to the brain.

With POTS, this response is disrupted. Blood may pool in the legs and abdomen. The heart may beat faster to compensate. The brain may receive less steady blood flow, especially during standing, heat, stress, meals, or long periods without movement.

POTS is not one single disease with one single cause. It is a syndrome, which means it describes a pattern of symptoms and body responses. Several pathways can lead to it.

Common contributors include:

• Autonomic nervous system dysfunction

  The nerves that control blood vessel tightening may not respond strongly enough.

  
  

• Low blood volume

  Some people with POTS appear to have less circulating blood volume, which can make upright posture harder.

  
  

• Hyperadrenergic activity

  The body may release higher levels of stress-related chemicals when upright, leading to shakiness, palpitations, and anxiety-like physical symptoms.

  
  

• Neuropathic changes

  Small nerve fibers in the lower body may not signal blood vessels properly.

  
  

• Deconditioning after illness or inactivity

  Bed rest, viral illness, surgery, or prolonged flares can reduce cardiovascular conditioning.

  
  

• Hypermobility and connective tissue differences

  Some people with POTS also have joint hypermobility or connective tissue disorders. This can affect blood vessel support and body awareness.

  
  

POTS can begin after an infection, concussion, pregnancy, surgery, growth spurts, or a period of major stress on the body. For some, the cause remains unclear.

How POTS can affect proprioception

Proprioception comes from sensors in muscles, tendons, joints, and skin. These sensors tell the brain where the limbs are, how much force a muscle is using, and whether the body is leaning, stepping, reaching, or turning.

The brain combines that information with input from vision and the inner ear. When all three systems work well together, movement feels automatic. When they do not, the body may feel unreliable.

POTS can interfere with this in several ways.

Reduced blood flow to the brain may cause dizziness, blurred vision, and delayed processing. That can make balance feel less secure. A person may know they are standing, but their brain may not process body position with the same clarity.

Muscle fatigue also matters. When leg and core muscles tire quickly, joints may feel less supported. The body relies more heavily on visual cues, such as watching the floor while walking.

For people with hypermobile joints, proprioception can be further challenged. Loose or unstable joints may send less precise feedback. This can lead to bumping into doorframes, rolling ankles, dropping objects, or feeling unsure on stairs.

Proprioception helps the brain track balance, pressure, and joint position.

Symptoms that may show up day to day

POTS symptoms vary from person to person. They can also change from day to day, which can make the condition hard to explain.

Common symptoms include:

• Fast heart rate when standing

• Lightheadedness or near-fainting

• Fainting in some cases

• Palpitations

• Fatigue that feels out of proportion to activity

• Brain fog

• Headaches

• Nausea or digestive changes

• Shortness of breath with upright activity

• Shakiness or internal trembling

• Heat intolerance

• Exercise intolerance

• Cold or discolored hands and feet

• Poor sleep

  
  

Proprioception-related symptoms may include:

• Feeling off balance in busy spaces

• Stumbling or tripping more often

• Needing to look at the feet while walking

• Difficulty standing still

• Feeling worse in the dark or with eyes closed

• Trouble judging how much force to use

• Clumsiness during flares

  
  

These symptoms can be frightening, especially when tests look “normal” or people around the person do not understand what is happening. Many individuals with POTS spend months or years being told they are anxious, out of shape, or overreacting. Anxiety can occur alongside POTS, but POTS symptoms are not simply imagined.

POTS can affect school, work, parenting, exercise, social plans, and basic chores. Standing in line, showering, cooking, grocery shopping, or walking across a parking lot can become draining.

One difficult part is the unpredictability. A person may manage a short walk one day and struggle to sit upright the next. Heat, dehydration, menstrual cycles, poor sleep, large meals, and infections can all trigger symptoms.

The proprioception piece can add emotional strain. Feeling unsteady can reduce confidence. Some people avoid stairs, crowds, uneven ground, or exercise because they fear falling or triggering symptoms. Over time, that avoidance can lead to more deconditioning, which can worsen POTS symptoms.

Support matters. So does language. Saying “just exercise more” is rarely helpful. A better approach is structured, paced, and medically guided movement that respects the body’s limits.

Small changes at home can make daily tasks less exhausting.

Treatment often works best as a combined plan

There is no single treatment that works for every person with POTS. Care usually works best when it addresses circulation, nervous system regulation, strength, and daily triggers.

Common treatment tools may include:

• Fluids and salt

  Many clinicians recommend increased fluids and salt for some people with POTS, unless another condition makes this unsafe. This should be personalized.

  
  

• Compression garments

  Waist-high compression or abdominal compression may help reduce blood pooling.

  
  

• Graded exercise

  Recumbent or semi-recumbent exercise, such as rowing, swimming, or using a recumbent bike, is often easier at first than upright workouts. Progress should be gradual.

  
  

• Physical therapy

  A therapist familiar with dysautonomia and hypermobility can help build leg, hip, and core strength. Balance training and proprioceptive exercises may include controlled weight shifts, resistance work, step training, and joint position practice.

  
  

• Pacing and trigger management

  Sitting for grooming, using shower chairs, cooling strategies, smaller meals, and rest breaks can reduce flares.

  
  

• Medication

  Some people benefit from medications that affect heart rate, blood volume, or blood vessel tone. Examples may include beta blockers, ivabradine, fludrocortisone, or midodrine. These require medical supervision.

  
  

• Care for related conditions

  Migraine, mast cell activation symptoms, Ehlers-Danlos syndromes, anemia, thyroid disease, vestibular disorders, and autoimmune conditions may need evaluation when symptoms suggest them.

  
  

A helpful plan often starts small. Drinking fluids consistently, wearing compression during upright tasks, and doing brief floor-based strengthening may be more realistic than jumping into a full exercise program.

Proprioceptive training can start with safe, supported movements.

A more hopeful way to understand the connection

POTS can make the body feel unpredictable. Proprioception problems can make that feeling even stronger, especially when dizziness, fatigue, weakness, or joint instability enter the picture. Still, these symptoms have real body-based explanations, and many people improve with the right mix of medical care, pacing, hydration support, compression, and gradual rehabilitation.

The goal is not to force the body through symptoms. The goal is to understand what the body is struggling to regulate, then support it step by step.

For anyone living with these symptoms, being believed is part of care. So is finding clinicians who understand dysautonomia/POTS and can look beyond a single normal test result. With the right support, daily life can become more stable, movement can feel safer, and the body can start to feel a little more like home again.
