Foods to Avoid with POTS | Dietary Tips for Managing Symptoms

How Diet Impacts POTS Symptoms

Managing foods to avoid with POTS is essential for reducing symptoms like dizziness, fatigue, and heart rate fluctuations. Certain foods can disrupt circulation, hydration, and blood pressure stability, making dietary choices a key factor in symptom management.

Blood Pressure Regulation and Circulation

Many individuals with POTS experience difficulty regulating blood pressure, often leading to lightheadedness when standing. Certain foods can influence blood pressure either positively or negatively. Highly processed foods rich in artificial additives and sodium may cause sudden fluctuations, leading to discomfort and worsened symptoms.

Conversely, nutrient-dense options like lean proteins, whole grains, and potassium-rich vegetables help stabilize circulation and support consistent blood pressure levels throughout the day. Consuming these foods in well-balanced portions can promote better cardiovascular function and minimize extreme highs or lows.

Hydration and Electrolyte Balance

Proper hydration is essential for managing POTS, as dehydration can trigger increased heart rate and dizziness. Caffeinated beverages, alcohol, and excessive sodium can contribute to dehydration and electrolyte imbalance, worsening symptoms. Instead, focusing on water, electrolyte-rich fluids, and hydrating fruits ensures the body maintains adequate fluid levels to support circulation.

Some POTS patients find benefits in increasing their sodium intake, but this should be done carefully with guidance from a healthcare provider. Natural sources such as sea salt, olives, and broth-based soups can offer electrolyte support without relying on heavily processed options.

Blood Sugar Stability

Since blood sugar fluctuations can lead to crashes in energy, avoiding refined sugars and processed carbohydrates is key. Pastries, candies, and sodas can create temporary energy spikes followed by sharp declines, exacerbating fatigue and brain fog. Instead, prioritizing complex carbohydrates like quinoa, brown rice, and legumes helps maintain steady blood sugar levels, improving endurance and focus.

By making informed dietary choices, individuals with POTS can minimize symptom triggers and create a more stable foundation for daily health and well-being. Food selection, hydration strategies, and mindful nutrient intake all contribute to managing symptoms effectively.

For individuals with Postural Orthostatic Tachycardia Syndrome (POTS), maintaining stable blood sugar levels is crucial for managing symptoms. Consuming refined sugars and highly processed carbohydrates often leads to rapid blood sugar spikes, followed by sudden crashes, triggering fatigue, dizziness, and brain fog. These fluctuations can strain the autonomic nervous system, making it harder for the body to regulate circulation and energy.

Why They’re Problematic

Processed carbs are quickly absorbed, causing a surge in blood glucose levels. The body responds by releasing insulin, which lowers blood sugar but often leads to an abrupt energy drop, exacerbating POTS-related fatigue and instability. Additionally, these foods are typically low in essential nutrients, depriving the body of fiber and protein needed for sustained energy.

Sugary and processed foods can also worsen inflammation, impacting vascular function and contributing to poor circulation, a common concern for POTS patients.

Examples of High-Sugar and Processed Carbs to Avoid

• Candy and pastries – High in refined sugars, leading to energy crashes
• Sugary cereals – Often contain artificial additives and excessive sugar
• White bread and baked goods – Made with processed flour, lacking fiber
• Sodas and sweetened beverages – Provide sugar overload without hydration benefits

Healthier Alternatives

Instead of processed carbs, prioritizing nutrient-dense foods can help regulate blood sugar while providing steady energy. Beneficial swaps include:

• Whole grains like quinoa, brown rice, and oats – Promote stable glucose levels
• Fruits such as berries, apples, and oranges – Offer natural sweetness paired with fiber
• Legumes like lentils and chickpeas – Provide protein and complex carbs for sustained energy

High-Sodium Processed Foods

While sodium can be beneficial for some POTS patients to manage low blood pressure, consuming sodium from processed sources can worsen symptoms. Many packaged and fast foods contain excessive preservatives, artificial additives, and unhealthy fats, which can negatively impact circulation, inflammation, and hydration levels.

Why Processed Sodium Is Harmful

Processed sodium sources often contain chemical stabilizers that can disrupt fluid balance, leading to bloating and irregular blood pressure regulation. Additionally, packaged meals often combine sodium with refined oils and unhealthy fats, making them difficult to digest and potentially inflammatory.

Consuming too much processed sodium can also contribute to dehydration, interfering with electrolyte balance, which is crucial for maintaining blood flow and hydration in POTS patients.

Examples of High-Sodium Processed Foods to Avoid

• Chips and salted crackers – Often contain unhealthy trans fats alongside high sodium
• Fast food meals – Loaded with excessive salt and artificial flavor enhancers
• Frozen meals and canned soups – High sodium levels combined with preservatives
• Processed meats like bacon, sausages, and deli cuts – Contain nitrates and artificial stabilizers

Healthier Alternatives

Instead of processed sodium sources, choosing natural electrolyte-supporting foods can help maintain hydration and blood pressure stability. Ideal options include:

• Sea salt and Himalayan salt – Provide minerals without harmful preservatives
• Olives and pickles – Offer sodium with additional nutrients
• Homemade broth-based soups – Support hydration with natural electrolytes
• Avocados, bananas, and spinach – Help balance sodium intake with potassium for better circulation

Caffeinated and Energy Drinks

For individuals with Postural Orthostatic Tachycardia Syndrome (POTS), caffeine can be a problematic stimulant. While some may tolerate it in moderation, excess consumption often leads to dehydration, increased heart rate, and nervous system overstimulation. Many energy drinks also contain high levels of sugar and artificial ingredients, further intensifying symptoms like lightheadedness and palpitations.

Why Caffeine Is Harmful for POTS Patients

Caffeine stimulates the central nervous system, triggering an increase in heart rate and sometimes worsening autonomic dysfunction. Additionally, it is a diuretic, meaning it promotes fluid loss through increased urination. This can lead to dehydration, which is already a concern for POTS patients due to difficulty regulating blood pressure and circulation.

Many caffeinated beverages also contain artificial additives, preservatives, and high sugar content, which can further disrupt blood sugar stability and nervous system function.

Examples of Caffeinated and Energy Drinks to Avoid

• Coffee (especially strong brews and espresso) – Can cause rapid heart rate increases and dehydration
• Soda (cola and other high-caffeine soft drinks) – Often contains excess sugar alongside caffeine
• Energy drinks (Red Bull, Monster, etc.) – Loaded with stimulants, artificial ingredients, and excessive sugar
• Strong black and green teas – Can contain moderate to high levels of caffeine

Healthier Alternatives

For those who enjoy caffeine, limiting intake and opting for milder sources can be helpful. Consider these alternatives:

• Herbal teas (chamomile, peppermint, rooibos) – Naturally caffeine-free and beneficial for digestion
• Decaffeinated coffee or low-caffeine teas – Maintain the taste without overstimulating the nervous system
• Electrolyte-infused water or coconut water – Hydrating and supportive of circulation
• Homemade fruit-infused water – Adds flavor without the dehydration risk of caffeine

Alcohol

Alcohol presents multiple risks for POTS patients due to its ability to dehydrate the body and affect vascular function. As a vasodilator, alcohol widens blood vessels, which can lead to drops in blood pressure, resulting in dizziness or lightheadedness. Additionally, alcohol is diuretic, meaning it promotes fluid loss, further worsening circulatory and hydration issues.

Why Alcohol Is Harmful for POTS Patients

POTS patients already struggle with blood pressure regulation, and alcohol can exacerbate these difficulties. By widening blood vessels, it can lead to sudden blood pressure drops, causing fatigue, weakness, and instability when standing.

Moreover, alcohol affects electrolyte balance, making it harder for the body to maintain proper hydration and circulation. Many alcoholic beverages also contain added sugars, which may contribute to blood sugar fluctuations and energy crashes.

Examples of Alcohol to Avoid

• Beer and wine – Can promote dehydration while also affecting electrolyte levels
• Cocktails with high sugar content – Combine alcohol’s negative effects with blood sugar instability
• Hard liquors (vodka, whiskey, rum, etc.) – Strong vasodilators that increase heart rate fluctuations
• Mixed drinks with stimulants – Some cocktails include caffeine-based mixers, making their impact even worse

Healthier Alternatives

If alcohol must be consumed, moderation and hydration are key. Some POTS patients find the following to be better tolerated:

• Non-alcoholic beverages like sparkling water or herbal teas – Provide refreshment without negative effects
• Diluted alcohol options (wine spritzers, low-alcohol beers) – Help maintain electrolyte balance with less impact
• Hydration strategies (water between drinks, electrolyte replenishment) – Minimize dehydration risks

Instead of fried foods, opting for lighter, nutrient-dense meals can improve digestion and reduce post-meal fatigue:

• Grilled or baked lean proteins (chicken, fish, tofu) – Provide energy without circulation issues
• Air-fried vegetables and sweet potatoes – Offer texture and taste without unhealthy oils
• Olive oil, avocado, and nuts – Healthy fats that promote circulation instead of inflammation

Excess Dairy

While dairy is not inherently harmful, some POTS patients experience heightened symptoms when consuming large quantities of milk-based products. Factors like lactose intolerance, casein sensitivity, and excess saturated fat intake can lead to bloating, digestive distress, and systemic inflammation.

Why Dairy Can Be Problematic

Dairy may slow digestion, causing discomfort and sluggish circulation—especially in individuals with sensitive digestive systems. Additionally, high-fat dairy products may interfere with electrolyte balance, impacting hydration levels. Some individuals with POTS may also experience neurological reactions to dairy proteins, leading to fatigue and brain fog.

Examples of Dairy Products to Limit

• Milk, cheese, and ice cream – Common sources of lactose and casein sensitivity
• Heavy cream-based sauces – Can increase bloating and digestive discomfort
• Flavored yogurts and processed dairy snacks – Often contain added sugars and artificial stabilizers

Healthier Alternatives
