If your symptoms get worse at ovulation — or after wine or cheese — this is for you.
Histamine isn’t just about allergies or hay fever. It’s actually a neurotransmitter, and it helps regulate serotonin and dopamine. It also has a tight relationship with oestrogen:
• When oestrogen increases → histamine increases
• When histamine increases → oestrogen increases
So at ovulation, when oestrogen surges, you can also get a histamine spike. This can show up as:
• Insomnia
• Anxiety
• Feeling wired
• Skin rashes or hives
• Headaches
• Gut flares
• PMDD-type symptoms
A simple first step?
Try a short-term low histamine diet — taking out things like alcohol, aged cheese and fermented foods.
