Diagnosis

Histamine intolerance is usually confirmed if symptoms have improved after being on a low-histamine diet for two weeks.

Treatment

Symptoms associated with histamine intolerance are usually only triggered when there is a substantial increase in histamine levels in the body. So, it is possible to still eat foods containing histamine. In fact, it is very rare that histamine has to be completely eliminated from your diet if histamine intolerant.

However, it is usually advised not to eat a combination of high histamine containing foods as these can accumulate to levels that will trigger symptoms. It is thought that taking regular anti-histamine tablets may help relieve symptoms.

For those who have a low level of diamine oxidase, supplements to increase the enzymes activity such as vitamin B6 or vitamin C may be useful.
