If you’ve read my post on eating well with Ehlers-Danlos Syndrome, you already know that EDS is a connective tissue disorder that affects far more than just your joints. It affects multiple body systems — and for a significant number of people with EDS, the autonomic nervous system is one of them. That’s where POTS comes in. This post is for every zebra navigating both. 🦓👇
What Is POTS?
POTS stands for Postural Orthostatic Tachycardia Syndrome. It’s a form of dysautonomia — a disorder of the autonomic nervous system, the part of your nervous system that controls involuntary functions like heart rate, blood pressure, digestion, and breathing.
In POTS, when you move from lying down or sitting to standing, your heart rate spikes dramatically — typically by 30 beats per minute or more in adults, or 40+ bpm in children — within 10 minutes of standing, while blood pressure remains normal or drops. The result is a cascade of symptoms that can be profoundly debilitating:
- 💫 Dizziness and lightheadedness upon standing
- ❤️ Racing heart rate (tachycardia) when upright
- 😴 Extreme fatigue — often described as a full-body exhaustion that sleep doesn’t fix
- 🧠 Brain fog — difficulty concentrating, word-finding, memory
- 🤢 Nausea and GI symptoms — slow gastric motility, bloating, nausea
- 💧 Exercise intolerance — even mild exertion can trigger a flare
- 🥶 Temperature dysregulation — difficulty handling heat or cold
- 😴 Sleep disturbances — unrefreshing sleep, nighttime heart rate irregularities
POTS predominantly affects women — an estimated 80% of patients — and most commonly strikes between ages 15 and 50. It is profoundly under-diagnosed, and many patients spend years being told their symptoms are anxiety or “all in their head” before receiving a proper diagnosis. Sound familiar? 🦓
POTS & EDS: The Zebra Comorbidity
POTS is one of the most common comorbidities of Ehlers-Danlos Syndrome — and the connection is not coincidental. It’s structural.
In EDS, faulty collagen affects the walls of blood vessels, making them more stretchy and compliant than they should be. When you stand up, blood is supposed to be pushed back upward efficiently by vessel walls and surrounding connective tissue. In EDS, those vessels don’t snap back the way they should — blood pools in the lower body, less returns to the heart, and the heart compensates by racing to maintain circulation. That’s POTS.
Research published in peer-reviewed literature on dysautonomia and hypermobility syndromes confirms that EDS and POTS frequently co-occur, and that nutritional management is a cornerstone of treatment for both conditions simultaneously. If you have EDS and have ever felt dizzy standing up, had a racing heart for no apparent reason, or crashed hard after mild activity — it is worth having a conversation with your doctor about POTS. 💚
In EDS, faulty collagen makes blood vessels too stretchy. When you stand, blood pools downward instead of returning to the heart — and POTS is the result. It’s not anxiety. It’s connective tissue. 🦓
Salt Is Medicine for POTS — Not the Enemy
Here is one of the most important things I want you to understand from this post: for most people with POTS, sodium is not something to limit — it’s something to actively increase. This is the complete opposite of what we’re told as a general population health message, and it catches a lot of POTS patients off guard.
Here’s why salt matters so much in POTS: sodium directly controls blood volume. More sodium = more fluid retained in the bloodstream = higher blood volume = better circulation when upright = fewer POTS symptoms. It’s that direct a relationship.
The 2021 POTS Expert Consensus Review — one of the most authoritative clinical guides on POTS management — recommends that most POTS patients consume 3,000–10,000mg of sodium per day, alongside 2–3 liters of water. That’s dramatically higher than the 2,300mg/day the general population is advised to stay under. The Cleveland Clinic echoes this, recommending between 3,000–10,000mg sodium daily for POTS patients. Some expert guidelines go as high as 10–12g of salt per day for the most symptomatic patients.
One practical tip from POTS specialists: drink a full glass of water with something salty about 30 minutes before getting out of bed in the morning. This pre-loads your blood volume before the orthostatic challenge of standing begins. It’s a simple habit that many POTS patients report as genuinely life-changing. 💪
⚠️ Important caveat: High sodium is recommended for most POTS patients, but NOT for those with the hyperadrenergic subtype of POTS, or those with hypertension, kidney disease, or heart failure. Always confirm your sodium targets with your doctor before significantly increasing intake. This is one area where individualization really matters.
Why Keto and POTS Are a Powerful Combination
This is where things get really interesting — because keto and POTS management align in several deeply complementary ways that most people never connect.
Keto already requires higher sodium intake. As I cover in detail in my complete guide to keto electrolytes, cutting carbs causes your kidneys to excrete more sodium — which is why keto dieters are encouraged to salt their food liberally, drink bone broth, and supplement electrolytes. The high sodium target that POTS requires? Keto is already built around supporting that. These two approaches were practically made for each other.
Carbohydrates directly worsen POTS symptoms. This is a critical connection. Large, carbohydrate-heavy meals divert massive blood flow to the digestive tract during digestion — and in POTS, where blood volume and circulation are already compromised, that diversion can trigger serious symptom flares. Dizziness, heart pounding, nausea, and crashes after meals are classic POTS post-meal symptoms — and they’re dramatically worsened by high-glycemic, high-carb eating. Cutting carbs on keto reduces this blood flow diversion significantly.
Blood sugar stability reduces POTS triggers. Blood sugar spikes and crashes are known to worsen POTS symptoms. The autonomic nervous system is highly sensitive to glycemic variability — and the blood sugar rollercoaster of a standard high-carb diet creates a constant low-grade autonomic stress. Keto eliminates that entirely. Stable glucose = less autonomic provocation = fewer flares.
Smaller, more frequent meals align with both keto and POTS management. POTS specialists universally recommend 4–6 small meals per day rather than 3 large ones — specifically to prevent the blood pooling that large meals trigger. Keto’s fat and protein-forward approach means meals are naturally more satiating in smaller portions. These approaches reinforce each other perfectly.
Keto is anti-inflammatory. POTS involves significant neuroinflammation and immune dysregulation in many patients. The anti-inflammatory nature of a well-formulated ketogenic diet — which I’ve also written about in the context of eating well with EDS — directly addresses this inflammatory component.
Keto supports better sleep, which POTS desperately needs. Sleep is profoundly disrupted in POTS — and poor sleep makes every POTS symptom worse. As I covered in my post on keto and sleep, the blood sugar stability and anti-inflammatory effects of keto create better conditions for deep, restorative sleep. For POTS patients, this is not a small thing.
The POTS + Keto Nutritional Blueprint
| Priority | POTS Recommendation | How Keto Supports It |
|---|---|---|
| Sodium | 3,000–10,000mg/day (doctor-guided) | Keto already requires higher sodium — built-in alignment |
| Fluids | 2–3 liters of water daily | Keto’s diuretic effect makes hydration even more critical |
| Meal size | 4–6 small meals vs. 3 large | High-fat, high-protein keto meals are naturally satiating in smaller portions |
| Carbohydrates | Minimize high-GI, high-carb meals | Keto eliminates the blood-flow diversion caused by large carb loads |
| Blood sugar stability | Avoid glucose spikes and crashes | Keto eliminates the blood sugar rollercoaster entirely |
| Magnesium | Important for nerve and muscle function | A keto priority — covered in the electrolytes guide |
| B vitamins (B1, B12) | POTS patients are frequently deficient | Prioritize eggs, meat, fish — all keto staples |
| Vitamin D | EDS-HT patients commonly deficient | Fatty fish, eggs, and supplementation — keto-compatible |
| Gluten | Consider gluten-free trial — POTS patients have higher celiac rates | Well-formulated keto is naturally gluten-free |
The Electrolyte Overlap: Where Keto & POTS Meet
If you have POTS — or suspect you might — my keto electrolytes post is essential reading, because the overlap between what keto requires and what POTS management requires is remarkable:
- 🧂 Sodium — both keto and POTS demand significantly higher intake than standard guidelines. On keto, aim for 3,000–5,000mg; on POTS, your doctor may recommend up to 10,000mg. Bone broth, salted foods, and electrolyte supplements are your tools.
- 🥑 Potassium — works with sodium to regulate fluid balance and blood pressure. Essential for both keto and POTS. Avocado, spinach, and salmon are your best keto-friendly sources.
- 💊 Magnesium — supports nerve function, muscle relaxation, sleep, and heart rate regulation — all directly relevant to POTS. A priority on keto, and doubly so with POTS. Just remember to check for medication interactions if you’re on gabapentin or other prescriptions!
- 💧 Hydration — both keto (diuretic effect) and POTS (low blood volume) require significantly more water than the average person. 2–3 liters daily is a minimum for most POTS patients on keto.
POTS, Mood & Mental Health
One thing I want to name directly: POTS is relentless, and it takes a serious toll on mental health. The fatigue, the limitations, the brain fog, the feeling of your body constantly working against you — anxiety and depression are genuinely common in POTS, and they are not a character flaw. They are a physiological consequence of living with a dysregulated autonomic nervous system and chronic illness.
Keto’s emerging role in mental health — including the research I covered in my post on keto and mental health — makes it particularly relevant for the POTS community. Stable blood sugar, reduced neuroinflammation, and steady ketone fuel for the brain all support a more stable mood and clearer cognition. These aren’t small benefits when you’re managing a condition that affects your nervous system 24 hours a day.
You deserve support for the whole of what you’re carrying — not just the physical symptoms. 💛
Practical Daily Tips for POTS on Keto
Start your morning with salt and water before getting up. Keep a glass of water and something salty — crackers, a small cup of bone broth, or a pinch of sea salt in water — on your nightstand. Drink it 20–30 minutes before standing. This is one of the single most impactful daily habits for POTS management.
Never eat a large meal. Especially not a carb-heavy one. Smaller, more frequent keto meals — every 3–4 hours — keep blood flow more evenly distributed and prevent the post-meal crash that large meals trigger in POTS.
Sip fluids consistently throughout the day. Don’t chug large amounts of water at once — spread your fluid intake across the whole day. Electrolyte drinks help retain fluid in the bloodstream better than plain water alone.
Salt your food generously — and mean it. On keto you already should be doing this. With POTS, it becomes non-negotiable. Sea salt on everything. Bone broth daily. Electrolyte supplements. This is the one time the saltshaker is your friend without reservation.
Be cautious with alcohol and caffeine. Alcohol is a vasodilator and diuretic that worsens blood pooling — anecdotally, many POTS patients find it significantly worsens their symptoms. Caffeine has a more variable response — some POTS patients find it helpful for vasoconstriction, others find it worsens heart rate or anxiety. Know your own response before making it a daily habit.
Work closely with your medical team. POTS management is highly individual. The sodium targets, fluid goals, and dietary approaches that work for one person may not work for another — particularly depending on your POTS subtype. This post is a starting point for conversation with your doctor, not a substitute for personalized medical guidance. 💚
The Bottom Line
POTS is complex, underdiagnosed, and profoundly misunderstood — especially in its relationship to EDS. But the connection between POTS management and a ketogenic lifestyle is one of the most natural overlaps in the entire chronic illness nutrition space. Both demand higher sodium. Both benefit from blood sugar stability. Both are supported by electrolyte-rich, anti-inflammatory eating. Both improve with smaller, more frequent meals.
If you’re a zebra navigating POTS alongside EDS, you are not alone — and you are not imagining it. Your body is working harder than most people will ever understand. What you eat every day is one of the most powerful tools you have. Use it. 🦓💛
