Histamine Intolerance: What You Should Know

Histamine intolerance is a condition that causes an increase in histamine levels in the body. Although it is not a dangerous condition, it can cause more serious issues if not managed properly. Find out what you should know about this condition and what to do if you are experiencing symptoms of this disorder.

What is Histamine Intolerance?

Histamine intolerance is an adverse reaction to histamine, a natural compound found in foods and beverages. Histamine can cause a wide range of symptoms, including headache, flushing, nausea, vomiting, diarrhoea, and abdominal pain.

Histamine intolerance is most commonly caused by the ingestion of foods or beverages that contain high levels of histamine. The most common sources of histamine are egg whites and fermented products, such as soy sauce and cheese. However, histamine can also be produced naturally by the body during infection or inflammation.

If you experience any of the following symptoms after eating a food or beverage that contains high levels of histamine, consult your doctor: diarrhoea for more than three days, fever over 39 degrees Celsius (102 degrees Fahrenheit), difficulty breathing, swelling of the face or lips, or severe skin rash.

Causes of Histamine Intolerance

Histamine intolerance is a problem with the body’s ability to produce histamine. Histamine is a chemical that plays a role in the body’s immune system. Problems with histamine production can cause a number of problems, including hay fever, allergic reactions, and asthma. 

The most common causes of it are genetics and environmental factors. Some people are more likely to develop histamine intolerance because they have a specific gene that makes them particularly susceptible. Other people may become intolerant due to exposure to certain chemicals or foods. There is no one cause of histamine intolerance, but it can occur for many different reasons. 

If you think you may have it, it’s important to see a doctor. Your doctor will help determine the cause of your problem and recommend the best treatment for you.

The Effects and Symptoms of Histamine Intolerance

Histamine intolerance is a condition in which people develop an immune response that attacks the body’s histamine receptors. Histamine is a naturally occurring chemical in the body that helps to regulate blood pressure, heart rate, and other functions. 

When people with it consume foods or drinks that contain histamine, their immune systems overreact and create symptoms such as headache, cramps, diarrhoea, and even vomiting. In some cases, It can be mild and go unnoticed, but in others, it can be severe and lead to serious health problems. Start following a healthy diet if you are experiencing any histamine intolerance symptoms. There are several online diet plans that are widely available.  Visit to buy your course today.

Treatments for Histamine Intolerance

If you are experiencing symptoms of it such as an itchy skin rash, swollen sinuses, or hives, you should talk to your doctor about what treatment might be best for you. Your doctor will likely prescribe over-the-counter medications such as ibuprofen or acetaminophen, or they may refer you to a specialist who can prescribe a more specific medication.

There is also some evidence that dietary changes may help relieve symptoms of it. Some people find relief by avoiding foods that contain high levels of histamine, while others find relief by modifying their diet to include more complex carbohydrates and proteins. It is important to speak with your doctor about which approach is best for you.
