Histamine Intolerance: Everything You Need to Know

Histamine intolerance is a condition where the body is unable to process histamine properly, leading to a range of symptoms. In this article, we will explore what histamine intolerance is, its causes and symptoms, how it is diagnosed, and ways to manage and treat it.

What is Histamine Intolerance?

Histamine is a chemical that is released by the body's immune system in response to injury or allergens. It is also found in certain foods and drinks, such as fermented products, aged cheese, and wine. In people with histamine intolerance, the body is not able to properly break down histamine. This leads to an excess of histamine in the body, which can trigger a range of symptoms. These symptoms can be similar to those of an allergic reaction, but histamine intolerance is not an allergy.

Some common symptoms of histamine intolerance include headaches, hives, itching, flushing, and gastrointestinal issues such as diarrhea, nausea, and vomiting. These symptoms can be mild or severe and can occur immediately after consuming histamine-rich foods or several hours later. It is important for individuals with histamine intolerance to identify and avoid trigger foods, as well as work with a healthcare provider to develop a management plan.

Causes and Symptoms of Histamine Intolerance

There are several potential causes of histamine intolerance, including genetic factors, gut issues, and enzyme deficiencies. Symptoms of histamine intolerance can include headaches, migraines, dizziness, itching, hives, stomach pain, and diarrhea.

One of the most common causes of histamine intolerance is a deficiency in the enzyme diamine oxidase (DAO), which is responsible for breaking down histamine in the body. When DAO levels are low, histamine can build up and cause symptoms of intolerance.

In addition to genetic factors and enzyme deficiencies, certain foods can also trigger histamine intolerance. These include fermented foods, aged cheeses, alcohol, and processed meats. It is important for individuals with histamine intolerance to identify and avoid these trigger foods in order to manage their symptoms.

How is Histamine Intolerance Diagnosed?

Diagnosing histamine intolerance can be challenging, as there is no specific test for it. However, doctors can perform elimination diets and/or measure histamine levels in the blood or urine to help diagnose the condition.

Elimination diets involve removing high-histamine foods from the diet for a period of time, and then gradually reintroducing them to see if symptoms return. This can help identify which foods trigger symptoms and can guide dietary changes to manage the condition.

In addition to elimination diets, doctors may also measure histamine levels in the blood or urine. High levels of histamine in these samples can indicate histamine intolerance. However, it is important to note that histamine levels can fluctuate and may not always be a reliable indicator of the condition.

Common Foods and Drinks that Trigger Histamine Intolerance

People with histamine intolerance should avoid or limit certain foods and drinks that are high in histamine or trigger histamine release. These include fermented foods and drinks, aged cheese, sauerkraut, canned fish, shellfish, spinach, and alcohol.

It is important to note that some foods may not be high in histamine themselves, but can still trigger histamine release in the body. These include citrus fruits, strawberries, tomatoes, chocolate, and nuts. It is recommended that individuals with histamine intolerance keep a food diary to track their symptoms and identify any trigger foods.

How to Manage Symptoms of Histamine Intolerance through Diet

A low histamine diet can be helpful for managing histamine intolerance. This involves avoiding or limiting high histamine foods, as well as foods that may trigger histamine release. Foods that can be included in a low histamine diet include fresh fruits and vegetables, fresh meat, certain grains, and dairy substitutes. Additionally, it may be helpful to eat smaller, more frequent meals, as larger meals can lead to histamine release.

It is also important to note that some individuals with histamine intolerance may benefit from incorporating certain supplements into their diet. These may include vitamin C, vitamin B6, and copper, which can help to support the body's natural histamine breakdown processes. However, it is important to consult with a healthcare professional before starting any new supplements, as they may interact with other medications or health conditions.

Supplements for Managing Histamine Intolerance

There are several supplements that may be helpful for managing histamine intolerance. These include quercetin, vitamin C, DAO (diamine oxidase), and probiotics. Quercetin and vitamin C are natural antihistamines, while DAO is an enzyme that helps break down histamine. Probiotics can also help improve gut health and reduce histamine levels.

In addition to supplements, it is also important to avoid foods that are high in histamine or that trigger the release of histamine in the body. Some common culprits include aged cheeses, fermented foods, alcohol, and processed meats. Keeping a food diary and working with a healthcare professional can help identify trigger foods and develop a personalized plan for managing histamine intolerance.

Medications for Treating Histamine Intolerance

Medications may also be prescribed to help manage histamine intolerance, such as antihistamines, mast cell stabilizers, and corticosteroids. However, these medications may have side effects and should be used under the guidance of a medical professional.

It is important to note that medications should not be the only form of treatment for histamine intolerance. A low-histamine diet, avoiding trigger foods, and reducing stress can also be effective in managing symptoms. It is recommended to work with a healthcare provider to develop a comprehensive treatment plan.

Lifestyle Changes for Managing Histamine Intolerance

Along with diet and supplements, making certain lifestyle changes can be helpful for managing histamine intolerance. Stress reduction techniques, such as meditation or breathing exercises, may help reduce histamine release. Additionally, avoiding extreme temperatures, such as hot baths or cold weather, can also help reduce histamine release.

Regular exercise can also be beneficial for managing histamine intolerance. However, it is important to avoid high-intensity workouts that can trigger histamine release. Instead, low to moderate intensity exercises such as yoga, walking, or swimming can help reduce stress and inflammation, which can in turn help manage histamine intolerance symptoms.

Understanding the Link between Mast Cell Activation Syndrome and Histamine Intolerance

Mast cell activation syndrome (MCAS) is a condition where the body's mast cells are overactive and release excess histamine. This can lead to symptoms similar to those of histamine intolerance. While MCAS and histamine intolerance are not the same, there is often overlap between these two conditions. Understanding this link can be helpful for proper diagnosis and treatment.

histamine intolerance can be a challenging condition to manage, but with the right approach, it is possible to reduce symptoms and improve quality of life. By following a low histamine diet, taking appropriate supplements or medications, and making certain lifestyle changes, individuals can manage histamine intolerance and lead a healthier life.

It is important to note that while MCAS and histamine intolerance share some similarities, they are distinct conditions with different underlying causes. MCAS is a result of an overactive immune system, while histamine intolerance is caused by an inability to break down histamine properly. Therefore, treatment approaches may differ depending on the specific condition.

Research into the link between MCAS and histamine intolerance is ongoing, and there is still much to learn about these conditions. However, by working closely with a healthcare provider and following a personalized treatment plan, individuals with either condition can find relief from their symptoms and improve their overall quality of life.
