Many people with postural orthostatic tachycardia syndrome (POTS) struggle to find answers for persistent symptoms like rapid heartbeat, dizziness, and brain fog. This blog post dives into the often-overlooked connection between mast cell activation syndrome (MCAS) and POTS, explaining how overactive mast cells can fuel these symptoms. You’ll also learn practical steps and treatment approaches that could help improve your quality of life by targeting the immune system’s role in POTS.

For those with mast cell activation syndrome (MCAS), dysautonomia (including postural orthostatic tachycardia syndrome/POTS), or Ehlers-Danlos syndrome (EDS)/hypermobility spectrum disorder (HSD), heat isn't just uncomfortable—it can be a powerful trigger. This blog post unpacks how hot weather impacts the immune system, autonomic nervous system, and connective tissue, often leading to delayed flares that are easy to miss. Learn how heat affects each condition, why symptoms might not appear until hours later, and which proactive cooling strategies can help protect your body. Staying cool isn’t just a comfort measure—it’s critical symptom management.

Persistent mast cell activation syndrome (MCAS) symptoms like fatigue, hives, and brain fog may be triggered by everyday household products—even if you're following a strict diet and treatment plan. In this blog post, we uncover hidden mast cell triggers in household products like cleaners, skincare, laundry products, and air fresheners, and explain how chemicals, fragrances, and preservatives can silently worsen flares. You’ll also learn how to choose MCAS-friendly alternatives to create a safer, low-trigger home environment. If your symptoms aren’t improving, your household products could be the missing piece.

Neck, shoulder, and upper back pain may seem like simple muscle tension—but in some cases, it’s something far more complex. Coat hanger pain is a distinctive pain pattern often linked to conditions like postural orthostatic tachycardia syndrome (POTS), other forms of dysautonomia, Ehlers-Danlos syndrome (EDS), hypermobility spectrum disorder (HSD), and mast cell activation syndrome (MCAS), yet it is frequently overlooked or misdiagnosed. In this blog post, we explain what coat hanger pain really is, why it happens, and how it connects to broader circulatory and autonomic issues. You’ll also learn about practical strategies for relieving discomfort and improving daily function. If your pain worsens when upright and eases when lying down, this may be the clue you’ve been missing.

What if your brain fog, panic, or fatigue were not caused by a mental health condition? Mast cell activation syndrome (MCAS) is an often-overlooked immune disorder that can mimic anxiety, depression, attention-deficit/hyperactivity disorder (ADHD), or trauma—leading many to be misdiagnosed for years. In this blog post, we break down what MCAS really is, how it disguises itself as a mental health issue, and what to look for if traditional treatments have not helped. With research suggesting MCAS may affect 1 in 6 people, it could be the missing piece you—and your doctors—have been overlooking.

For people with mast cell activation syndrome (MCAS), a walk outside isn’t always refreshing—it can be a minefield of invisible triggers. From pollen, sunlight, and insect stings to temperature swings and air pollution, the outdoors can quietly provoke symptoms like rashes, dizziness, and fatigue. This blog post unpacks common outdoor triggers for MCAS, why reactions can feel so unpredictable, and how to navigate the outdoors without losing your sense of joy or control. If you’ve ever felt worse after being outside and didn’t know why, this is for you.

For people with mast cell activation syndrome (MCAS), even a simple leftover meal can lead to a symptom flare. That’s because histamine builds up in foods the longer they’re stored—even in the fridge—and reheating doesn’t eliminate it. In this blog post, we break down why leftovers can trigger symptoms like headaches, nausea, and skin reactions, and share practical tips for safer food prep, storage, and symptom tracking. If you’ve been reacting to meals you once trusted, this might be the missing link.

Not every racing heartbeat, dizzy spell, or shaky moment is “just stress.” Conditions like mast cell activation syndrome (MCAS), postural orthostatic tachycardia syndrome (POTS) or other forms of dysautonomia, and Ehlers-Danlos syndrome (EDS)/hypermobility spectrum disorder (HSD) can produce anxiety-like symptoms—but with very different underlying causes. In this blog post, we unpack why these medical conditions are so often mistaken for stress, the red flags that it’s something more, and how misdiagnosis can delay effective treatment. You’ll also learn when to push for deeper evaluation, especially if anxiety treatment hasn’t worked. If your symptoms are persistent, unexplained, or resistant to treatment, this could be the missing piece.

Mast cell activation syndrome (MCAS) is complex, and managing it requires more than just one thing. In this blog post, we explore a layered approach that combines trigger avoidance, medications, nutrition, nervous system support, and better sleep to help calm mast cell reactivity over time. Whether you’re just starting your MCAS journey or fine-tuning your care plan, this guide shows how building support across multiple layers can create a stronger, more stable path toward healing.

Mast cell activation syndrome (MCAS) is often misunderstood as a skin-only condition—but many people living with it have no visible symptoms at all. This blog post explores why focusing solely on hives, flushing, or itching can delay diagnosis and dismiss real suffering. Learn how MCAS impacts multiple organ systems—from the gut to the brain to the cardiovascular system—and why recognizing its invisible nature is critical for proper care, earlier diagnosis, and patient validation.

Struggling to fall asleep or waking up wired at 2 a.m.? For people with mast cell activation syndrome (MCAS), nighttime can bring a surge of symptoms—thanks in part to rising histamine levels while you sleep. This blog post explains how mast cells disrupt rest, why sleep issues are so common with MCAS, and what you can do to finally get a more restorative night’s sleep. If your insomnia feels unpredictable and exhausting, you’re not imagining it—and there are ways to take back control.

Living with mast cell activation syndrome (MCAS) can feel unpredictable—but there is a pattern hiding beneath the chaos. Identifying your unique symptom triggers is one of the most powerful steps toward gaining stability and reducing flares. This blog post walks you through the most common MCAS triggers (from heat and fragrances to food and mold), how to track them, and why awareness—not full avoidance—is the key to long-term resilience. If you’ve felt like your symptoms come out of nowhere, this is where clarity begins.

If your symptoms have been dismissed as anxiety, hormones, or poor sleep—but nothing quite adds up—it may be time to learn about mast cell activation syndrome (MCAS). This condition affects the immune system and can cause widespread, fluctuating symptoms that are often mistaken for irritable bowel syndrome (IBS), anxiety, or chronic fatigue. In this blog post, we break down the all-too-common pattern of misdiagnosis, explain what MCAS really is, and explore why awareness matters—especially for those who’ve been searching for answers for years.

Attention-deficit/hyperactivity disorder (ADHD) is widely known as a neurodevelopmental condition, while mast cell activation syndrome (MCAS) is often viewed through the lens of immunology. But what happens when symptoms like brain fog, fatigue, and sensory overload blur the lines between them? This blog post explores the emerging research on the potential link between ADHD and MCAS—from shared symptoms and neuroinflammation to what it means for diagnosis and treatment.
