Histamine & Hormones
Histamine is an endogenous chemical messenger that regulates immune responses, digestion, and the sleep-wake cycle. In many women, histamine symptoms intensify with the cycle, during perimenopause, or under chronic stress — because estrogen, cortisol, and histamine breakdown are closely connected.

Glossary
DAO (Diaminoxidase)
Diaminoxidase (DAO) is the enzyme that breaks down histamine in the gut. Reduced DAO activity causes histamine to accumulate in the body, triggering symptoms such as headaches, skin reactions, or digestive issues.
Read definitionEstrogen
Estrogen is a group of female sex hormones that regulate the menstrual cycle, bone health, and cognitive function. Estrogen also influences DAO activity and thus histamine breakdown, which can explain cycle-dependent symptoms.

Frequently asked questions
What is histamine intolerance?
Histamine intolerance describes a reduced ability to break down histamine in the body. Symptoms range from skin flushing and digestive issues to headaches.
Why do histamine symptoms change during the menstrual cycle?
Estrogen can reduce the activity of the enzyme DAO, which breaks down histamine in the gut. In many women, histamine symptoms intensify in the second half of the cycle or during hormonal transition phases.
