POTS Symptoms and Hydration: Staying Hydrated Can Help Manage POTS

How Staying Hydrated Can Help Manage POTS

Postural Orthostatic Tachycardia Syndrome (POTS) is a condition that affects the autonomic nervous system, leading to an abnormal increase in heart rate when standing. Managing POTS can be challenging, but one strategy that has proven helpful for many people is staying well-hydrated.

Common Symptoms of POTS and Dehydration

One of the difficulties in managing POTS is that its symptoms often overlap with those caused by dehydration. Common POTS symptoms include:

• Rapid heart rate (tachycardia) when standing
• Dizziness and lightheadedness
• Fatigue
• Low blood pressure
• Nausea

Interestingly, these are also symptoms many people experience when they are dehydrated. This overlap can sometimes make it difficult for people with POTS to identify if they are dealing with dehydration or a flare-up of their condition. However, staying properly hydrated has been shown to ease many of these symptoms.

Why Hydration is Crucial for POTS Patients

For individuals with POTS, proper hydration helps increase blood volume and maintain stable blood pressure. People with POTS often have a low blood volume (a condition known as hypovolemia), which contributes to many of their symptoms. Increasing fluid intake can help counteract this.

When you drink enough fluids, especially those that contain electrolytes like sodium, your body retains more water in your bloodstream. This helps prevent blood from pooling in the legs, which can reduce the dizziness and fainting episodes that often accompany POTS.

How Much Should You Drink?

Doctors often recommend POTS patients drink between 2 to 3 liters of fluid per day. However, it's important to spread this intake throughout the day, rather than drinking a large amount all at once. Taking small sips consistently helps the body better absorb the fluids, improving hydration without overwhelming your kidneys.

The Role of Electrolytes and Salt

While water is essential, drinking water alone isn't always enough for people with POTS. Electrolytes—particularly sodium—are key to helping the body retain the fluids it needs. Sodium is crucial because it helps the body hold onto water rather than quickly excreting it. This is why doctors often recommend increasing salt intake for POTS patients (unless contraindicated by other health issues).

Some people may be advised to use oral rehydration solutions (ORS) or salt supplements to balance their electrolyte levels. These solutions contain a mix of salt, sugar, and water that helps the body absorb fluids more effectively. For some, intravenous fluids may also be an option, particularly during severe POTS flare-ups.

Tips for Staying Hydrated with POTS

1. Start your day with water: Drink a glass of water before you even get out of bed. This helps combat the low blood volume that can occur overnight and helps prepare your body for the stress of standing.
2. Add electrolytes: Sports drinks or specially formulated electrolyte solutions can help improve hydration. Avoid those high in sugar, as excessive sugar can cause a rapid spike and drop in blood sugar, leading to more symptoms.
3. Increase salt intake: Most POTS patients benefit from increasing their daily salt intake to around 3-5 grams. This can come from salty foods or supplements, but always consult with your doctor before making significant dietary changes.
4. Drink throughout the day: Instead of chugging large amounts at once, sip fluids regularly to maintain a steady hydration level.
5. Avoid dehydration triggers: High altitudes, extreme heat, caffeine, alcohol, and certain medications can all worsen dehydration. Try to avoid these or balance them with extra hydration.
6. Eat water-rich foods: Foods like cucumbers, watermelon, and broth-based soups can help you stay hydrated while also providing electrolytes and other nutrients.

Conclusion

While hydration is not a cure for POTS, staying well-hydrated can significantly reduce the severity of symptoms like dizziness, rapid heart rate, and fatigue. Incorporating fluids and electrolytes into your daily routine can help manage POTS and improve your overall quality of life.

Remember, always consult with your healthcare provider to determine the right hydration strategy for your individual needs. By staying hydrated and balancing electrolytes, you can take an important step toward managing POTS more effectively.
