You can develop POTS suddenly or it can develop gradually.
Symptoms happen immediately or a few minutes after sitting up or standing. Lying down may relieve some of the symptoms.
POTS has several possible symptoms, and they vary from person to person. Symptoms include:
POTS symptoms often get worse in the following situations:

Researchers aren’t sure yet what exactly causes POTS. Currently, they think there are multiple causes, which they’ve grouped into different subtypes of POTS, including:
There’s also growing evidence suggesting that POTS might be an autoimmune disease, meaning your immune system attacks healthy tissue for unknown reasons.
POTS can be difficult for healthcare providers to diagnose due to the many symptoms that can occur over time. People with POTS may have symptoms for months to years before finally being diagnosed with the condition.
A healthcare provider will ask questions about your symptoms, medications and medical history. They’ll also perform a physical exam.
A tilt table test is the main way providers diagnose POTS. The tilt table test measures your heart rate and blood pressure as you change posture and position.

Besides the tilt table test, your provider may order other tests to help confirm a POTS diagnosis or rule out other possible causes of your symptoms, including:
Unfortunately, there’s no cure for POTS. Instead, healthcare providers use several strategies to manage the symptoms of POTS. Treatment is highly individualized based on your symptoms and what works best for you.
The main forms of treatment include:
Medical compression stockings can also help push blood up from your legs to reduce POTS symptoms.
Exercise and physical activity are key to managing POTS.
Although most people with POTS have healthy hearts, your provider may recommend a cardiac rehab program. This exercise template uses the cardiac rehab model to recondition and help improve health and manage POTS. Some of the best data for treating POTS comes from cardiac rehab.
Studies show that reclined aerobic exercise, such as swimming, rowing and recumbent bicycling, has the best results. Strengthening your core and leg muscles is also helpful.

Here are important things to know as you undergo an exercise program and other physical activities. Talk with your provider for specific instructions on these exercises.
Managing diet and nutrition is another important aspect of managing POTS symptoms.
If you have the hypovolemic (low blood volume) form of POTS, your healthcare provider will likely recommend increasing both your fluid and salt intake to increase blood volume.
Eating a large meal can make symptoms of POTS worse, as your body redirects a lot of blood to aid in the digestion process. Because of this, providers often recommend eating several smaller meals throughout the day instead of two or three large ones.
A nutritionist or dietitian can help you with your diet. This consult can be especially helpful if you have celiac disease or other dietary sensitivities.
General guidelines for dietary changes include:
The U.S. Food and Drug Administration (FDA) hasn’t approved any medications for POTS treatment. But healthcare providers sometimes prescribe medications off-label to help certain POTS symptoms.
These medications include:
All of these medications have potential side effects. Your provider will work with you to see if medication is right for you.
Aside from exercise and dietary changes, other things you can do to manage POTS include frequently monitoring your pulse and blood pressure and getting quality sleep.
Taking and writing down your blood pressure and pulse can provide insight into POTS and helps your healthcare provider fine-tune your treatment.
Check your blood pressure and pulse at the same time daily (in the morning and after dinner). It’s very helpful to do this for the first few months of your diagnosis. Also, check your blood pressure and pulse when you aren’t feeling well.
You can get a blood pressure monitor at most drug stores, online or at a medical supply store
POTS can disrupt your sleep. As sleep is very important for overall health, you should prioritize it. These general guidelines may help you:
Talk to your provider if POTS is significantly disrupting your sleep.
The prognosis (outlook) for POTS is generally good, although it can severely disrupt daily living. POTS symptoms may come and go for years. In approximately 80% of cases, the condition improves, but many people have residual symptoms.
The biggest risk to people with POTS is getting hurt if they faint and fall.
People with POTS have a normal life expectancy. The condition doesn’t decrease life expectancy.
Unfortunately, there’s nothing you can do to prevent developing POTS. But there are steps you can take to try to prevent flare-ups by knowing what your triggers are.
Some general guidelines for preventing flare-ups include:
Postural orthostatic tachycardia syndrome can be challenging to live with. Here are some things you can do to take care of yourself:
If standing up causes unusual symptoms, such as lightheadedness and a pounding heart rate, see a healthcare provider.
If you have POTS, try to see a healthcare provider who specializes in POTS to get the best care. You’ll also need a primary care physician to go to for routine care and health wellness management.
Learning that you have postural orthostatic tachycardia syndrome (POTS) can be overwhelming. Know that there are several treatments and lifestyle adaptations that can help manage your symptoms. No two people with POTS are affected in the same way, so it’s important to receive individualized care that’s unique to your situation. Don’t be afraid to ask your healthcare provider questions about POTS. They’re available to help you.
