What is POTS?

Postural orthostatic tachycardia syndrome (POTS) is a disorder of the autonomic nervous system that causes a rapid increase in heart rate when you move from lying down to standing up.

While anyone can develop POTS, it most commonly affects women between the ages of 15 and 50.

It causes a variety of symptoms, including gastrointestinal issues, and can significantly impact daily life.

Symptoms

Symptoms of POTS may include:

• Rapid heartbeat upon standing.
• Low blood pressure.
• Dizziness or lightheadedness.
• Fatigue.
• Shakiness.
• Brain fog.
• Headaches.
• Gastrointestinal (GI) issues, such as delayed gastric emptying, heartburn, nausea, vomiting, diarrhea, and constipation.

Triggers

Several factors can trigger or exacerbate POTS symptoms, including:

• Dehydration.
• Low-salt diet.
• Alcohol.
• Prolonged standing.
• Hot temperatures, including a hot shower or bath.
• Strenuous exercise.
• Stress or illness.
• Certain medications.
• Large meals.

How Does Diet Impact POTS?

Since there is no known cure for POTS, diet can play an important role in managing POTS symptoms.

Eating a diet that includes a bit of extra salt and staying adequately hydrated can help maintain blood volume and stabilize blood pressure.

Additionally, certain dietary changes can improve gastrointestinal symptoms associated with POTS, such as delayed gastric emptying.

Overall, people with POTS can better manage their condition by maintaining a healthy, well-balanced diet.

General Dietary Guidelines for POTS

Following certain dietary guidelines can help manage POTS symptoms.

Here are some general recommendations to consider:

• Increase fluid intake. Staying well-hydrated can help increase blood volume and reduce symptoms of POTS. Aim for at least 2-3 liters of fluids each day.
• Increase salt intake. Consuming more salt can help retain fluid and increase blood volume. While recommendations vary, slowly adding up to 10 grams of salt to your diet each day can help improve low blood pressure upon standing.
• Eat small, frequent meals. Smaller, more frequent meals can reduce symptoms of lightheadedness and dizziness upon standing and avoid GI upset.
• Focus on nutrients. Eating a well-balanced diet that emphasizes fruits, vegetables, whole grains, and lean proteins can help alleviate the gastrointestinal symptoms associated with POTS.
• Avoid alcohol. ​​It's recommended to limit or avoid alcohol if you have POTS. Alcohol can dehydrate the body and affect blood pressure, potentially worsening symptoms.

Foods to Include in a POTS Diet

When managing POTS symptoms, including the right foods in your diet can help.

Here are some beneficial foods to include in a POTS diet:

• Water-rich fruits and vegetables like cucumbers, celery, lettuce, watermelon, and oranges.
• High-sodium foods such as pickles, olives, pretzels, cheese, anchovies, and salted nuts.
• Protein-rich foods including chicken, turkey, fish, eggs, beans, legumes, and tofu.
• Complex carbohydrates like oatmeal, whole wheat bread, brown rice, farro, and quinoa.
• Probiotic-containing foods such as yogurt, kefir, sauerkraut, kimchi, miso, and sourdough.

Foods to Avoid

Certain foods can make POTS symptoms worse.

Here is a list of foods that should be limited or avoided if you have POTS:

Caffeine and Alcohol

Caffeine and alcohol can both exacerbate symptoms of POTS.

Caffeinated beverages like coffee, tea, and energy drinks can raise heart rate and cause dehydration by increasing urine production.

This can potentially worsen symptoms like dizziness, lightheadedness, and fatigue.

Caffeine can also aggravate gastrointestinal issues such as diarrhea and heartburn.

Alcohol dehydrates the body and can lower blood pressure, worsening symptoms like lightheadedness and fainting in people with POTS.

High-Sugar Foods and Refined Carbs

If you have gastrointestinal issues from POTS, reducing your consumption of high-sugar foods and refined carbohydrates can help alleviate symptoms.

Too much sugar can disrupt gut bacteria, potentially leading to GI symptoms like diarrhea.

Examples of high-sugar foods and refined carbohydrates include:

• White bread, pasta, and rice.
• Pastries and donuts.
• Desserts such as cookies, cakes, and ice cream.
• Candies and chocolate.
• Soda, sweetened coffee drinks, and other sugar-sweetened beverages.

Processed and High-Fat Foods

Processed foods are typically packed with added sugars and unhealthy fats, which can trigger gastrointestinal issues.

High-fat options like fried foods, fast food, and processed meats such as bacon and sausage are particularly problematic for those with POTS.

These foods can worsen symptoms like delayed gastric emptying, heartburn, nausea, constipation, and diarrhea.

Here are some processed and high-fat foods to limit:

• Fried foods like French fries, fried chicken, and Chinese takeout.
• Fast foods such as burgers, chicken nuggets, and pizza.
• Processed meats including bacon, sausage, and hot dogs.
• Snack foods like potato chips and packaged cookies.
• Bakery items such as donuts, cakes, and pastries.

Specific Triggers for Individuals

Triggers for POTS symptoms can vary widely among individuals, particularly regarding gastrointestinal issues.

Some people with POTS find relief by avoiding or reducing their intake of specific foods or food groups such as gluten, dairy, FODMAPs, and other foods that can irritate the digestive system.

Keeping a detailed food diary can be invaluable in identifying these individual triggers and making personalized dietary adjustments to better manage your condition.

Sample Meal Plan for POTS

Here's a sample POTS meal plan that includes six small meals and snacks, a minimum of 64 fluid ounces of water throughout the day, and incorporates salty foods:

• Breakfast: Oatmeal with fresh berries, chopped salted almonds, and a dollop of plain Greek yogurt. Drink 8 ounces of decaffeinated coffee, decaffeinated tea, or herbal tea.
• Snack: Smoothie made with kefir, natural salted peanut butter, frozen mixed berries, and fresh baby spinach. Drink 8 ounces of water.
• Lunch: Turkey sandwich made with whole wheat bread, deli turkey slices, cheddar cheese, avocado, and lettuce. Drink 16 ounces of water.
• Snack: Hummus with celery and salted pretzels. Drink 8 ounces of water.
• Dinner: Grilled salmon marinated in soy sauce, sautéed bok choy, and quinoa cooked in chicken stock and seasoned with salt. Drink 16 ounces of water.

This meal plan includes a mix of lean protein, complex carbs, healthy fats, salty foods, and hydrating foods to help manage POTS symptoms.

Adjust portions and foods based on your preferences and dietary needs.
