No rash, no flushing, no food reactions — just a heart that keeps misbehaving while every test comes back normal. https://rootcausa.com/blog/atypical-mcas-and-il-33/ Fri, 04 Sep 2026 12:16:00 +0300 https://rootcausa.com/blog/atypical-mcas-and-il-33/ Some people have every sign of mast cell activation but normal test results. A second switch on the mast cell, triggered by tissue damage rather than allergy, may explain why. https://rootcausa.com/blog/omega3-and-arrhythmias/ Thu, 03 Sep 2026 20:37:48 +0300 https://rootcausa.com/blog/omega3-and-arrhythmias/ <p><img src="https://rootcausa.com/blog/images/fish.png" alt=""></p> <h2 id="the-heart-needs-fats-to-function">The heart needs fats to function</h2> <p>A person eats what is generally considered a healthy diet: seed oil in the salad dressing, chicken breast, almost no fish, some roasted sunflower seeds. Low in fat and low in animal products. The heart still skips beats at night.</p> <p>The heart is partly built from fat. Every cardiomyocyte membrane is made of phospholipids, and the fatty acids in those membranes determine how well the ion channels work.</p> https://rootcausa.com/blog/histamine-mcas-and-arrhythmias/ Thu, 03 Sep 2026 20:31:38 +0300 https://rootcausa.com/blog/histamine-mcas-and-arrhythmias/ <p><img src="https://rootcausa.com/blog/images/mcas.png" alt="Mast cells releasing histamine and other mediators"></p> <h2 id="a-common-pattern">A common pattern</h2> <p>A person eats aged cheese, drinks a glass of red wine, and by midnight the heart is racing. In other cases there is no food involved at all. A hot shower or a stressful phone call is enough to bring on palpitations.</p> <p>What links these situations is often histamine, released by mast cells.</p> <h2 id="what-histamine-is">What histamine is</h2> <p>Histamine is a small molecule the body produces on purpose. It is stored inside <strong>mast cells</strong>, which are immune cells found in the skin, gut, lungs, sinuses, and the heart. It is released when those cells are triggered.</p> https://rootcausa.com/blog/oxidative-stress-and-arrhythmias/ Thu, 03 Sep 2026 20:31:38 +0300 https://rootcausa.com/blog/oxidative-stress-and-arrhythmias/ <p><img src="https://rootcausa.com/blog/images/oxidation.png" alt=""></p> <h2 id="a-common-pattern">A common pattern</h2> <p>A person finishes a heavy fried dinner, lies down, and within an hour the chest starts fluttering. Or wakes up at 3 AM with a pounding heart after a day of poor sleep, skipped meals, and too much coffee.</p> <p>Nothing unusual in the diet. No allergens. No wine, no cheese. The heart still reacts. One likely cause is oxidative stress.</p> <p>When reactive oxygen species (ROS) accumulate faster than antioxidants can neutralise them, the ion channels stop working normally. Sodium channels stay open longer than they should, calcium handling becomes imprecise, and potassium currents weaken. The action potential becomes unstable. This is the mechanism behind a large share of triggered arrhythmias in hearts that are structurally normal.</p> https://rootcausa.com/blog/salicylates-and-heart-arrhythmias/ Thu, 03 Sep 2026 20:31:38 +0300 https://rootcausa.com/blog/salicylates-and-heart-arrhythmias/ <blockquote> <p>Salicylate problems often occur together with MCAS (check the other post), but they are not the same thing. One is a detox pathway that cannot keep up, the other is an overactive mast cell. They overlap often enough to be confused, and often enough to coexist.</p> </blockquote> <h2 id="what-salicylates-are">What salicylates are</h2> <p>Salicylates are natural chemicals found in many plants, where they act as a defence against insects and disease. They are present in fruits, vegetables, spices, herbs, nuts, teas, essential oils, and in aspirin (acetylsalicylic acid).</p> https://rootcausa.com/blog/mold-and-arrhythmias/ Thu, 03 Sep 2026 20:31:38 +0300 https://rootcausa.com/blog/mold-and-arrhythmias/ <p><img src="https://rootcausa.com/blog/images/mold.jpg" alt=""></p> <h2 id="mold-and-the-heart">Mold and the heart</h2> <p>A person moves into an older rental with a humidity problem, or starts working in a basement office that smells musty. A few months later the heart starts behaving abnormally: PVCs at rest, a run of fluttering at night, a pulse of 110 while sitting on the couch.</p> <p>The cardiologist finds nothing. The ENT finds nothing. The cause may be the dark spot in the ceiling corner.</p> https://rootcausa.com/privacy/ Wed, 02 Sep 2026 00:00:00 +0000 https://rootcausa.com/privacy/ RootCausa sets no cookies and runs no analytics today.
