@ashleyt.rd: If histamine keeps flaring, food isn’t the root cause. Your body is struggling to clear histamine. these are some root causes I see most often👇 1️⃣ Sluggish liver & impaired detox pathways Your liver plays a huge role in histamine and hormone clearance. When detox pathways are overwhelmed: • Histamine isn’t broken down efficiently • Estrogen gets recirculated • Immune activation increases 2️⃣ MCAS (mast cell activation syndrome) Mast cells release histamine as part of your immune response. With MCAS, these cells are over-reactive, releasing histamine too easily. Triggers can include: • Stress & nervous system dysregulation • Infections & chronic inflammation • Hormone fluctuations • Environmental exposures 3️⃣ Gut dysbiosis & intestinal inflammation Your gut can either regulate histamine or create more of it. • Certain bacteria produce histamine • Inflammation increases histamine absorption • SIBO, parasites, yeast, or infections raise histamine load A healthy microbiome should help you tolerate foods, not react to everything. 4️⃣ Hormonal imbalances (especially estrogen dominance) Histamine and estrogen have a bi-directional relationship 🔁 • Estrogen increases histamine release • Histamine stimulates more estrogen This creates a vicious cycle! Why a low histamine diet alone isn’t the answer… It may calm symptoms temporarily, but it doesn’t address why histamine is high, and long-term restriction often worsens nutrient depletion and tolerance. #histamineintolerance #estrogendominance #detox #rootcausehealing #figpartner
