It was another taco night at my house, with the kitchen counter overflowing with taco shells, chips, and an all-time favorite: guacamole. Once the kids settled down with their plates, I loaded up my nachos with guac and dove in. Just minutes later, I felt uncomfortably full and nauseous. I dismissed it as a one-time occurrence until it happened again the following week. (Yes, we love our taco nights.)
Have you ever noticed symptoms like constipation, diarrhea, dizziness, heartburn, or an itchy throat after meals? Does your nose become runny or congested while enjoying a glass of wine? Do you ever feel queasy after eating a salad or pasta with tomato sauce? Or perhaps you’ve felt heightened anxiety after indulging in steak or a slice of chocolate cake? It’s surprising how comfort foods can sometimes lead to discomfort. A variety of symptoms can indicate histamine intolerance.
What Is Histamine Intolerance?
Histamine intolerance arises when there’s an imbalance between “accumulated histamine and the ability to degrade it.” According to ENT and Allergy, histamine is ingested through food and stored in nearly all tissues, playing a key role in keeping your body functioning properly.
How widespread is histamine intolerance? While exact figures are unclear, it’s estimated that about 1-3% of individuals may have this condition. However, as awareness grows and diagnostic methods improve, this number could rise.
Symptoms of Histamine Intolerance
When histamine levels are out of balance, symptoms can vary widely in severity. Common reactions include hives, itchy or flushed skin, red eyes, facial swelling, runny nose, and even asthma attacks. Other symptoms may involve blood pressure drops, heart palpitations, anxiety, or panic attacks. Gastrointestinal issues like bloating, stomach pain, constipation, and diarrhea are also prevalent; personally, I experience dizziness, anxiety, and a racing heart.
Why Some People Develop Histamine Intolerance
Several factors can lead to histamine intolerance. Certain medications may hinder the function of DAO (diamine oxidase), the enzyme responsible for breaking down histamine in the digestive system. This includes antidepressants, pain relief medications, and antibiotics. Gastrointestinal conditions such as leaky gut syndrome can also impair DAO’s effectiveness. A diet high in histamine-rich foods, along with genetic predispositions, can further exacerbate the issue. Deficiencies in vitamins and minerals like B-6, C, zinc, or copper, chronic stress, injuries, and alcohol consumption may also contribute.
Discovering Histamine Intolerance
Identifying histamine intolerance is challenging. Symptoms can be inconsistent and mimic various other conditions, including GI disorders and food allergies. There’s no definitive test, and diagnoses often come from allergists, functional medicine doctors, or through personal investigation using food-symptom diaries and elimination diets. Many individuals, including myself, have spent significant amounts on medical consultations before uncovering their histamine intolerance.
Treatment Options for Histamine Intolerance
Managing histamine intolerance can be complex. A low-histamine diet is often quite restrictive. Is it realistic to avoid beloved foods like wine, chocolate, grilled items, and cheese indefinitely? Many in the histamine intolerance community have explored various strategies, including adopting a lower-histamine diet, taking DAO supplements, probiotics, and carefully tracking their “histamine bucket” to prevent overconsumption and reactions. Others seek guidance from knowledgeable allergists or dietitians. Because the understanding of histamine intolerance is still evolving, there’s no universal treatment plan.
My own histamine intolerance was revealed serendipitously while working with a dietitian for another condition. By tracking my food intake and symptoms, we noticed a pattern linking my discomfort to high-histamine foods. After trying a low-histamine diet, my symptoms improved significantly. I’m grateful to have identified the cause of my issues, which previously left me fatigued and unable to sleep well. However, this journey has had its challenges, as not everyone recognizes histamine intolerance as a legitimate concern. Nevertheless, I’m thankful I advocated for myself and learned how to manage my health better.
