Welcome to Idaho Brain & Body’s information page on Postural Orthostatic Tachycardia Syndrome (POTS). POTS is a condition where your heart beats much faster than usual when you stand up. This change in heart rate can make you feel dizzy, lightheaded, or even faint. It’s like your heart and blood vessels don’t respond as they should when you move from sitting to standing. People with POTS might also experience fatigue, headaches, or a feeling of their heart racing. This condition often affects teenagers and young adults, especially women, but it can occur at any age. At Idaho Brain & Body, we understand that POTS can be challenging to live with, and we are dedicated to helping you manage your symptoms and improve your quality of life through personalized care and support.

Common Symptoms of POTS Syndrome

Postural Orthostatic Tachycardia Syndrome (POTS) is a disorder of the autonomic nervous system that primarily affects blood flow and heart rate. Common symptoms of POTS include:

Rapid Heartbeat (Tachycardia): A significant increase in heart rate upon standing, often by 30 beats per minute or more, is the hallmark symptom of POTS.

Lightheadedness or Dizziness: These symptoms are commonly experienced when standing up and can sometimes lead to fainting (syncope).

Fatigue: Persistent tiredness and exhaustion are frequently reported, not necessarily related to physical exertion.

Brain Fog: Cognitive difficulties such as trouble concentrating, memory problems, and feeling mentally “foggy” are common.

Headaches: Frequent headaches, which can range from mild to severe, are often experienced by individuals with POTS.

Palpitations: Sensations of a racing or fluttering heart are common, especially upon standing or during physical activity.

Tremors: Shaking or tremors, particularly in the hands, can occur when in the upright position.

Exercise Intolerance: Difficulty with physical activity and exercise, leading to rapid fatigue and worsened symptoms.

Gastrointestinal Symptoms: Issues such as nausea, abdominal pain, bloating, and constipation or diarrhea can occur.

Temperature Regulation Issues: Difficulty with regulating body temperature, leading to excessive sweating or feeling unusually cold.

Shortness of Breath: Some individuals experience a sensation of being unable to take a deep breath or feeling breathless.

The severity and combination of symptoms can vary widely among individuals with POTS. This variability, along with the overlap of symptoms with other conditions, can make diagnosis challenging. Proper management and treatment are essential for improving quality of life for those with POTS.

Factors That Contribute to POTS Syndrome

Postural Orthostatic Tachycardia Syndrome (POTS) is a multifactorial condition with several contributing factors, though its exact cause is often unclear. A significant subset of POTS cases develops after a viral infection, suggesting that post-viral autoimmunity might play a role. Genetic predisposition is another factor, as POTS sometimes appears to run in families, indicating a possible hereditary component. Hormonal changes can also influence POTS, with a higher prevalence observed in women, particularly during periods of hormonal fluctuation such as puberty, pregnancy, and menstruation. Some cases of POTS are associated with other underlying health conditions, such as Ehlers-Danlos Syndrome, a disorder affecting connective tissue, or conditions that affect the autonomic nervous system. Physical deconditioning, often resulting from prolonged bed rest or inactivity, can also contribute to the development of POTS. Additionally, traumatic events, both physical and emotional, have been linked to the onset of POTS in some individuals. The complexity of these factors and their interactions makes POTS a challenging condition to understand and manage, requiring a comprehensive and personalized approach to treatment.

Wow were my eyes opened by Dr. Z. I was suffering from daily migraines, neck, back, shoulder, hip pain, vision and hearing problems, and the list goes on. Dr. Z saved my life. No joke. He is super meticulous and very passionate about his work. He is very smart and forward thinking and researches all the time. He genuinely cares about his patients. He’s an amazing and very caring provider and I highly recommend him.

“Dr. Spencer Zimmerman is phenomenal! In January I found out I have Lyme disease and along with that discovery, I found out that most traditional Doctors won’t/can’t help treat Lyme disease patients due to FDA restrictions. My only option appeared to be a Lyme specialist, which was going to cost enormous amounts of money because insurance doesn’t cover Lyme specialists. I felt hopeless. And that’s when I had the amazing fortune to come across Dr. Spencer Zimmerman. He gave me the hope I so desperately needed. He is very knowledgeable in regards to traditional medicine, but also homeopathic care as well.
