POTS (Postural Orthostatic Tachycardia Syndrome)
Medically reviewed by Drugs.com. Last updated on Jun 5, 2024.
Postural orthostatic tachycardia syndrome (POTS) is a term used to describe a fast heart rate that happens when you sit up or stand. Tachycardia is a heart rate of 100 beats per minute or more at rest. POTS may be caused by cardiovascular system problems, low blood volume, or blood pooling in your legs when you stand. A high level of certain hormones or health problems from another disease or condition can also cause POTS.
DISCHARGE INSTRUCTIONS:
Call your local emergency number (911 in the US) or have someone call if:
- You have trouble breathing.
- You collapse or go unconscious when you try to stand.
Return to the emergency department if:
- You cannot stand for 1 minute because your heart rate is very high, or you feel too lightheaded.
- You have severe pain.
- You have vomiting or diarrhea that is not stopping.
Call your doctor if:
- You drink the recommended amount of liquid each day but are still having POTS symptoms.
- Your heart rate is higher than usual when you change position from lying to standing.
- Your brain fog or confusion is worse.
- You have muscle twitches.
- You cannot drink liquids as fast as you are sweating them out.
- Your lifestyle changes have made no change to your symptoms.
- You have questions or concerns about your condition or care.
Medicines:
- Medicines may be given to improve your heart rate or to increase your blood volume. Medicines may be given to help you build strength and energy. You may also need medicines to prevent or treat pain or nausea.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Manage POTS:
Your healthcare provider will help you create a specific plan to manage POTS. The plan may include these and other guidelines:
- Know what to do if you feel your heart rate increase. Remember to sit up or stand up slowly to prevent symptoms. If you still feel symptoms when you change position, sit or lie back down right away. Your provider may also show you ways to bring your heart rate down. For example, you may be told to squeeze a rubber ball or to tighten certain muscles.
- Check your heart rate (pulse) as directed. Your provider will show you how to check your pulse, and how often to check it. Write down how fast your pulse is and what you were doing if your pulse is above 100. Bring the information with you to your follow-up appointments.
- Exercise as directed. Your provider or a physical therapist can show you how to exercise safely at home. Aerobic exercise, such as walking, can help strengthen your heart and lungs. Resistance training, such as lifting weights, can help build muscle strength. Your provider or therapist will tell you how much exercise to get each day, and which exercises are best for you. You might need to start with a few minutes of exercise at a time.
- Avoid heat. Heat can trigger your symptoms. Stay inside during very hot days, or limit the amount of time you are outside. Do not take hot baths or sit in a sauna.
- Control other medical conditions that can cause or worsen POTS. Your provider can help you create a management plan. You may also be referred to a specialist, such as a cardiologist.
- Wear compression stockings as directed. Compression stockings are tight around your lower legs. The pressure helps increase blood flow and reduce any swelling you may have in your legs.
- Make changes to the foods you eat, if needed. Have small, regular meals throughout the day. Your provider or a dietitian can help you create meal plans. You may also need to have more salt, depending on the cause of your POTS. Your provider or dietitian can help you get the right amount of salt each day. Other changes may be recommended if you have nausea, vomiting, or digestion problems.
- Drink more liquid, as directed. Liquid can help prevent or relieve some symptoms of POTS. For example, liquid can prevent you from getting too hot and triggering symptoms. Your provider will tell you how much liquid you need, and how often to drink liquid. Your provider will tell you which liquids are best for you. Limit or do not drink alcohol. Too much alcohol may trigger or worsen symptoms of POTS.
- Get more sleep, if needed. Sleep can help you feel less tired during the day. Sleep with an extra pillow or a folded blanket under your pillow to keep your head and upper body raised. This may help prevent you from becoming dizzy or lightheaded when you stand up in the morning.
