If you've been experiencing dizziness, lightheadedness, or fainting, you may be wondering what's causing these symptoms. One possibility is postural orthostatic tachycardia syndrome (POTS), a condition that affects the way your body regulates blood pressure and heart rate when you stand up.
POTS is a relatively common condition, affecting up to 1 in 100 people. It is often seen with which causes the body's immune system to attack its own tissues, or in people with Ehlers Danlos Syndrome, a genetic disorder that affects the connective tissue.
In this article, we'll take a closer look at POTS, including its symptoms, causes, and treatment options. We'll also provide some tips for managing the condition.
What is POTS Syndrome?
POTS is a condition that affects blood pressure and heart rate.
- Fast heart rate on standing
- Lightheadedness or dizziness
- Fainting or near-fainting
- Fatigue and brain fog
- Rapid heartbeat and palpitations
- Chest pain or shortness of breath
- Nausea and vomiting
- Blurred vision
- Difficulty sleeping
POTS can be caused by a variety of factors, including dehydration, blood loss, and certain medications. It is also associated with certain medical conditions, such as Ehlers-Danlos syndrome and autoimmune disorders.
Fast heart rate on standing
One of the most common symptoms of POTS is a fast heart rate upon standing. This is because when you stand up, gravity pulls blood down to your legs, which can cause your blood pressure to drop. In people with POTS, their heart rate increases rapidly in an attempt to compensate for the drop in blood pressure.
- Normal heart rate response: When a healthy person stands up, their heart rate typically increases by 10-20 beats per minute. This is a normal response that helps to maintain blood pressure.
- POTS heart rate response: In people with POTS, their heart rate increases by more than 30 beats per minute when they stand up. This rapid increase in heart rate can cause a variety of symptoms, including lightheadedness, dizziness, and fainting.
- Causes of fast heart rate: The exact cause of the fast heart rate in POTS is not fully understood, but it is thought to be related to a combination of factors, including problems with the autonomic nervous system, which controls blood pressure and heart rate, and changes in blood volume.
- Impact of fast heart rate: The fast heart rate in POTS can have a significant impact on a person's quality of life. Symptoms can interfere with activities of daily living, such as work, school, and exercise. In some cases, POTS can also lead to more serious complications, such as stroke or heart attack.
If you are experiencing a fast heart rate upon standing, it is important to see a doctor to rule out any underlying medical conditions, including POTS.
Lightheadedness or dizziness
Lightheadedness or dizziness is another common symptom of POTS. This is because the fast heart rate and drop in blood pressure that occur when standing up can lead to a decrease in blood flow to the brain. This can cause a variety of symptoms, including:
- Feeling faint or like you might pass out
- Blurred vision
- Tunnel vision
- Nausea
- Vomiting
- Confusion
- Difficulty concentrating
Dizziness and lightheadedness can be very distressing and can interfere with a person's ability to perform everyday activities. In some cases, dizziness can also lead to falls, which can result in serious injuries.
There are a number of things that can trigger lightheadedness or dizziness in people with POTS. These include:
- Standing up too quickly
- Exercising
- Being in a hot or humid environment
- Dehydration
- Eating a large meal
- Alcohol consumption
- Certain medications
If you are experiencing lightheadedness or dizziness, it is important to see a doctor to rule out any underlying medical conditions. Your doctor may recommend lifestyle changes, such as increasing fluid intake, avoiding triggers, and performing exercises to improve blood flow, to help manage your symptoms.
In some cases, medication may be necessary to control the symptoms of POTS. There are a number of different medications that can be used to treat POTS, including beta-blockers, ACE inhibitors, and fludrocortisone.
Fainting or near-fainting
Fainting, or syncope, is a temporary loss of consciousness caused by a lack of blood flow to the brain. It is a common symptom of POTS, especially in people who experience severe drops in blood pressure when they stand up.
- What happens during a faint: When a person faints, their blood pressure drops suddenly, causing a decrease in blood flow to the brain. This can lead to a loss of consciousness, which typically lasts for a few seconds or minutes. In some cases, a person may experience a near-fainting spell, also known as presyncope, which is a feeling of lightheadedness or dizziness that is about to progress to a faint.
- Causes of fainting in POTS: The exact cause of fainting in POTS is not fully understood, but it is thought to be related to a combination of factors, including problems with the autonomic nervous system, which controls blood pressure and heart rate, and changes in blood volume.
- Triggers of fainting in POTS: There are a number of things that can trigger fainting in people with POTS, including standing up too quickly, exercising, being in a hot or humid environment, dehydration, eating a large meal, alcohol consumption, and certain medications.
- Risks of fainting in POTS: Fainting can be a dangerous symptom of POTS, especially if it occurs while a person is driving or operating machinery. Fainting can also lead to falls, which can result in serious injuries.
If you are experiencing fainting or near-fainting spells, it is important to see a doctor to rule out any underlying medical conditions. Your doctor may recommend lifestyle changes, such as increasing fluid intake, avoiding triggers, and performing exercises to improve blood flow, to help manage your symptoms. In some cases, medication may be necessary to control the symptoms of POTS and reduce the risk of fainting.
