Histamine intolerance

Okay kiddo, let me explain histamine intolerance to you. Histamine is a natural substance that our body produces to protect us from harmful things, like allergies, infections or injuries. It plays an important role in our immune system and helps us fight off diseases.

However, some people might have a condition called histamine intolerance. This means that their body is not able to break down histamine properly, leading to a build-up of histamine levels in their body. This can cause a range of symptoms, such as headache, flushing, itching, hives, nausea, stomach cramps, diarrhoea and many others.

Histamine intolerance can be triggered by consuming foods that are high in histamine, such as aged cheese, cured meats, fermented foods, alcohol and certain fruits and vegetables. It can also be caused by certain medications, like aspirin, or by bacterial overgrowth in the gut.

If you have histamine intolerance, your doctor might recommend a low histamine diet, which means avoiding or limiting high histamine foods. They might also prescribe medication to help you manage your symptoms.

Remember, histamine intolerance is not a life-threatening condition, but it can cause discomfort and inconvenience, so it's important to work with your doctor to find the best course of action for you.
