Nutrition support for MCAS, POTS, EDS, and chronic illness without making food another full-time job.
Nutrition care for complex, unpredictable symptoms that meets you where you are.
Living with MCAS, POTS, Ehlers-Danlos syndrome (EDS), or another chronic illness can make eating feel much more complicated than it “should.”
You might be dealing with nausea, early fullness, reflux, bloating, diarrhea, constipation, dizziness, fatigue, headaches, brain fog, flushing, food reactions, changes in appetite, or symptoms that seem to shift from one day to the next.
Maybe eating enough feels physically difficult. Maybe you are trying to figure out whether certain foods are contributing to symptoms. Maybe you have been told to increase fluids and sodium, follow a low-histamine diet, avoid certain foods, eat smaller meals, stabilize your blood sugar, or somehow do all of these things at once.
And when your body feels unpredictable, food can start to feel unpredictable too.
You may rely on familiar foods because they feel safer or easier to tolerate. You may struggle to cook when you are fatigued, dizzy, in pain, or experiencing a flare. You might feel like every symptom requires another dietary change, another supplement, or another thing to monitor.
Nutrition support does not have to mean chasing a perfect diet.
Whether you are navigating MCAS, POTS, EDS, or some combination of these conditions, nutrition care can help you nourish your body, make eating more manageable, and find strategies that fit your actual symptoms and capacity.
How an chronic illness-informed dietitian can help
We support nourishment without turning every symptom into another food rule.
Our work is collaborative, cautious, and individualized. Together, we look for practical ways to support nutrition, identify meaningful patterns, and reduce food-related fear while respecting your symptoms and medical care.
Look for meaningful patterns
Explore connections between symptoms, foods, meal timing, medications, stress, environment, and other possible triggers without assuming every reaction is caused by food.
Protect nutritional adequacy
Make sure you are getting enough energy, protein, carbohydrates, fats, fluids, and micronutrients when symptoms or a limited range of tolerated foods make consistent nourishment difficult.
Avoid unnecessary restriction
Evaluate whether dietary changes are actually helping and avoid removing broad categories of food without a clear purpose, plan, and way to assess the results.
Build reliable food options
Create flexible meals, snacks, grocery lists, and backup options using foods that currently feel accessible, tolerable, and realistic for your energy and capacity.
Reduce fear around eating
Work through the anxiety, hypervigilance, and uncertainty that can develop when reactions feel unpredictable or when online food lists make eating seem increasingly unsafe.
Coordinate with your care team
Collaborate with your allergist, gastroenterologist, primary care provider, and other clinicians so nutrition recommendations support your broader evaluation and treatment plan.
This care may be supportive if you’re navigating
POTS, dysautonomia, dizziness, lightheadedness, or difficulty maintaining hydration
fatigue, brain fog, migraines, flushing, itching, or symptoms that worsen during flares
MCAS, suspected food reactions, histamine intolerance, or questions about low-histamine eating
Ehlers-Danlos syndrome or hypermobility alongside GI symptoms, fatigue, pain, or difficulty eating consistently
difficulty shopping, cooking, or preparing food because of pain, fatigue, disability, or executive dysfunction
limited “safe foods” or fear around expanding your diet
The goal is not perfect eating. It’s more safety, more nourishment, and more confidence around food.

Nutrition Support That Looks at the Whole Picture
When you live with chronic illness, nutrition recommendations can pile up quickly. Each recommendation may have a reason behind it, but trying to follow all of them at once can leave you overwhelmed, undernourished, or afraid to eat.
Nutrition counseling gives us space to zoom out. We consider your symptoms, medical history, medications, eating patterns, hydration, GI tolerance, sensory preferences, energy levels, accessibility, food relationship, and co-occurring conditions. Then we figure out what actually deserves your attention.
POTS, Hydration, Sodium, and Electrolytes
If you have POTS or dysautonomia, you may have been encouraged to increase fluids and sodium to support blood volume. Nutrition counseling can help you develop a hydration routine that feels realistic.
Depending on your medical recommendations, we may explore electrolyte products, sodium-rich foods, timing of fluids, oral rehydration solutions, meal timing, caffeine, GI tolerance, and strategies for mornings or other times when symptoms are more intense.
MCAS, Food Reactions, and Trigger Confusion
With MCAS, reactions can be individual and inconsistent. A food may seem completely fine one day and appear to cause symptoms another day. You may experience flushing, itching, hives, nausea, diarrhea, reflux, headaches, dizziness, fatigue, or brain fog and have difficulty knowing what is actually responsible. Nutrition counseling can help you look for meaningful patterns without assuming every reaction means another food needs to be removed.
We may consider timing, portions, food preparation and storage, medications, stress, sleep, hormones, environmental exposures, overall intake, and your broader symptom threshold.
EDS, Hypermobility, and Nutrition
EDS and hypermobility can affect eating in ways that are easy to overlook. Pain and fatigue can make cooking difficult. GI symptoms can make meals uncomfortable. Early satiety, nausea, reflux, constipation, or motility concerns may make it difficult to eat enough. Joint pain or instability can even make shopping, chopping, opening containers, standing at the stove, or cleaning up harder.
Nutrition care can include much more than talking about nutrients. We can problem-solve easier foods, adaptive meal preparation, convenience options, meal structure, grocery strategies, supplements when appropriate, hydration, and ways to nourish yourself on days when your capacity is limited.
Nausea, Early Fullness, and GI Symptoms
MCAS, POTS, EDS, dysautonomia, medications, and other chronic conditions can overlap with digestive symptoms such as nausea, reflux, bloating, abdominal pain, constipation, diarrhea, and early fullness. These symptoms can make it harder to eat enough and easier to fall into restrictive patterns.
We may explore meal timing, hydration, fiber tolerance, texture preferences, nausea support, gentle meal structure, and ways to make eating feel more doable during flares. Nutrition support is tailored to what your body can tolerate right now.
Limited Safe Foods and Food Fear
If eating has repeatedly been followed by pain, nausea, allergic-type symptoms, dizziness, or other uncomfortable experiences, it makes sense that your brain may begin to associate food with danger.
Sometimes people start eliminating more and more foods in an attempt to gain control over unpredictable symptoms.
Nutrition counseling can help separate medically useful strategies from restriction driven by fear, conflicting food lists, or understandable hypervigilance.
If you want to expand your food options, we can approach that gently and collaboratively while respecting your symptoms and current capacity.
What sessions may include
Nutrition counseling that starts with your symptoms, not a generic food list.
You do not need to arrive with every trigger identified or follow an increasingly restrictive diet to deserve thoughtful nutrition support.
Understand the full picture
We review your symptoms, eating patterns, tolerated foods, medical history, medications, environment, and other factors that may be affecting how you feel.
Choose a focused next step
Rather than changing everything at once, we identify a practical nutrition strategy with a clear purpose and a way to evaluate whether it is actually helping.
Adapt as your needs change
We use your response as information, adjusting the plan while protecting nutritional adequacy and avoiding unnecessary food rules or self-blame.
CARE THAT LOOKS BEYOND THE FOOD LIST
Hi, I’m Alison
I’m Alison Swiggard, MS, RDN, LD, a non-diet registered dietitian specializing in eating disorders, chronic illness nutrition, and ADHD-friendly nutrition care. I especially enjoy working with people whose nutrition needs do not fit neatly into one box. You may be trying to manage POTS symptoms while struggling with nausea, navigating MCAS without wanting food fear to take over, figuring out how EDS and GI symptoms affect eating, or balancing chronic illness recommendations with a history of disordered eating.
We can be honest about what’s not working, let go of systems built for someone else’s brain, and create support that’s practical without becoming punitive.
Frequently Asked Questions
-
No, you do not need a formal MCAS diagnosis to reach out for nutrition support. If you are dealing with food reactions, suspected histamine intolerance, digestive symptoms, limited safe foods, or anxiety around eating, nutrition counseling can help you explore patterns and feel more supported. I may also recommend medical follow-up if your symptoms need further evaluation.
-
Not automatically. Low-histamine strategies can be helpful for some people, but they are not the right fit for everyone, especially if you have a history of disordered eating, chronic dieting, or a shrinking safe food list. We’ll talk through your symptoms, history, and needs before deciding what approach feels appropriate.
-
That is exactly the kind of situation where compassionate nutrition support can help. We would start by supporting adequacy, consistency, and safety with the foods that currently feel doable. Expansion can happen slowly and collaboratively when your body and nervous system have more support.
-
Yes, MCAS often overlaps with other chronic illness and digestive concerns. We can take the bigger picture into account, including hydration, salt needs, meal consistency, GI symptoms, fatigue, accessibility, and your relationship with food.
You’re in good company.
You don’t have to keep trying to solve your symptoms and relationship with food alone. If you’re tired of food fear, shrinking safe foods, and starting over with another list of rules, there’s another way to be supported. Schedule a free 15-minute consultation to talk through what’s been feeling hard with food and see whether nutrition counseling feels like a good fit.
