Understanding Histamine

Let’s start with the basics. What exactly is histamine, and why does it matter to your health?

What Is Histamine?

Histamine is a natural compound produced by cells in your body, particularly in response to various triggers such as inflammation, allergies, injuries, or perceived threats. While it’s an essential part of our immune system, playing a role in defending us against potential dangers, it can also be a troublemaker when its levels become excessive.

Breaking Down Histamine

The body has mechanisms to break down histamine and keep it in check. This process involves two key enzymes:

  1. HNMT (Histamine-N-Methyltransferase): This enzyme helps with methylation, a process that can neutralize excess histamine.
  2. DAO (Diamine Oxidase): DAO is responsible for breaking down histamine, particularly in your gut.

These enzymes act as our body’s natural regulators, ensuring that histamine levels remain balanced. However, when things go awry, histamine can accumulate and lead to a range of discomforting symptoms.

Histamine intolerance is a complex issue, and understanding its underlying causes is key to effectively managing it. In this section, we’ll delve into the five main causes of histamine intolerance, shedding light on what might be triggering your histamine-related symptoms.

1. Histamine-Producing Gut Bacteria

One of the most common culprits behind high histamine levels is an imbalanced gut, characterized by an overgrowth of certain gut bacteria. These bacteria are known as “histamine producers,” and when they multiply, they create a higher histamine load in your body. If you’ve undergone a GI Map Stool Test, you can check for elevated amounts of major histamine-producing bacteria like Morganella, Klebsiella, Pseudomonas, Citrobacter freundii, and others. Balancing your gut flora is essential to reducing histamine-producing bacteria and managing histamine intolerance.

2. Liver and Gallbladder Dysfunction

Your liver and gallbladder play a crucial role in regulating your gut microbiome over the long term. A compromised liver and gallbladder can lead to poor bile acid composition and regulation, creating an environment conducive to histamine-producing bacteria overgrowth. To address histamine intolerance effectively, it’s essential to focus on supporting these vital organs, allowing them to function more efficiently.

3. Methylation Status

Methylation is a biochemical process that helps break down histamine. Issues with methylation can hinder the proper breakdown of histamine, leading to its accumulation in your body. Understanding your methylation status, whether you’re an undermethylator, overmethylator, or normal methylator, can provide valuable insights. Depending on your status, you may benefit from dietary adjustments and supplements to support methylation and manage histamine intolerance.

4. Increased Histamine Release from Your Cells

Sometimes, histamine intolerance can be triggered when your body’s cells produce excessive histamine in response to various stimuli. These stimuli can range from allergens and contaminants (like mold and pollen) to injuries or perceived threats. Investigating potential food or environmental triggers is crucial when addressing histamine intolerance, as identifying and eliminating these triggers can be a key part of your strategy for symptom relief.

5. High Histamine Foods

The foods you consume play a significant role in histamine intolerance. Certain foods contain varying levels of histamine, and the longer a food sits in your fridge, the higher its histamine content tends to be. While short-term relief can be achieved by reducing high histamine foods through a low-histamine diet, long-term restriction is generally not recommended. Restrictive diets can have unintended health consequences. Instead, focusing on the root causes of histamine intolerance is the key to long-lasting relief.
