The Link Between POTS and Concussion: How Blood Pressure Changes Affect Recovery

Feb 20

Concussions can lead to a variety of unexpected symptoms, including dizziness, fatigue, and brain fog. For some individuals, these symptoms may be linked to Postural Orthostatic Tachycardia Syndrome (POTS)—a condition that affects blood flow and can develop after a head injury. If you’ve been experiencing lightheadedness, heart rate fluctuations, or trouble standing for long periods after a concussion, you may be dealing with POTS-related blood pressure changes.

Understanding the connection between POTS and post-concussion syndrome can help you take the right steps toward recovery. In this article, we’ll explore why concussions can trigger blood pressure dysregulation, how POTS symptoms present, and what treatment strategies can help.

What Is POTS?

POTS is a form of dysautonomia, a condition that affects the autonomic nervous system, which controls involuntary bodily functions such as heart rate, blood pressure, and digestion. Individuals with POTS experience a significant increase in heart rate when they transition from lying down to standing, often leading to dizziness, palpitations, and fatigue.

Research suggests that traumatic brain injuries (TBIs), including concussions, can disrupt autonomic nervous system function, increasing the risk of developing POTS-like symptoms.

If you’ve been struggling with dizziness and heart rate changes after a concussion, structured rehabilitation can help. The Concussion Solution offers a step-by-step approach to managing symptoms and improving recovery.

How Can a Concussion Lead to POTS?

A concussion can interfere with autonomic nervous system function in several ways:

Brainstem Dysfunction: The brainstem plays a key role in regulating blood pressure and heart rate. Concussions can cause temporary or prolonged dysfunction in this area.
Vagus Nerve Impairment: The vagus nerve helps regulate the cardiovascular system. A concussion can reduce its ability to control heart rate and blood pressure.
Inflammatory Response: Brain injuries trigger inflammation, which can contribute to autonomic dysregulation and worsen symptoms like dizziness and fatigue

These disruptions can lead to orthostatic intolerance, meaning the body struggles to adjust to changes in position, causing symptoms like lightheadedness, brain fog, and increased heart rate upon standing.

Symptoms of POTS After a Concussion

POTS symptoms can overlap with post-concussion syndrome, making it difficult to pinpoint the cause of ongoing issues. Common symptoms include:

Dizziness or lightheadedness when standing
Rapid heart rate increase upon standing (tachycardia)
Fatigue and brain fog
Exercise intolerance
Nausea or digestive issues
Cold hands and feet due to poor circulation

If these symptoms persist beyond the expected concussion recovery time frame, it may be worth discussing autonomic testing with a healthcare provider.

Research shows that specific interval training exercises can help regulate the autonomic nervous system after a concussion. By gradually reintroducing cardiovascular activity in a controlled manner, interval training can improve blood flow, reduce dizziness, and help restore nervous system balance. The Concussion Solution incorporates structured interval training to help you safely rebuild tolerance to exercise and support your recovery. Sign up here

Treatment Strategies for POTS and Concussion Recovery

While there is no single cure for POTS, several evidence-based strategies can help manage symptoms and improve quality of life.

1. Gradual, Monitored Exercise

Engaging in a graded exercise program has been shown to improve autonomic function over time.
Starting with recumbent exercises (such as cycling or rowing) before transitioning to upright activities can help reduce dizziness.
A study published in the Journal of Neurologic Physical Therapy found that structured aerobic exercise improved POTS symptoms in concussion patients.

2. Hydration and Electrolytes

Increasing fluid intake helps maintain blood volume, which can reduce dizziness and fatigue.
Electrolyte supplements or adding extra salt to meals can help stabilize blood pressure.

3. Physical Therapy for Autonomic Regulation

A specialized physical therapist can guide you through exercises designed to retrain your autonomic nervous system.
Vestibular therapy can help if dizziness and balance issues persist.
Breathwork and vagus nerve stimulation have been shown to improve autonomic function.

4. Medication and Lifestyle Adjustments

In some cases, medications like beta-blockers or fludrocortisone may be prescribed to help regulate blood pressure.
Compression garments can improve circulation and reduce blood pooling in the lower body.
Avoiding prolonged standing and using slow positional transitions can help prevent dizziness.

Want expert guidance on managing post-concussion symptoms? The Concussion Solution provides structured support for those dealing with lingering effects of concussion.

The link between POTS and concussion recovery is an emerging area of research, but it’s clear that autonomic dysfunction plays a role in lingering symptoms for many individuals. If you’re struggling with unexplained dizziness, fatigue, or blood pressure changes after a concussion, it’s essential to explore treatment options that address both the brain and the autonomic nervous system.

With the right combination of exercise, hydration, physical therapy, and lifestyle adjustments, many people see significant improvements over time.
