GUT HEALTH · FOOD INTOLERANCES
Nutritionist for food intolerances and histamine in Lisbon and online
When the list of foods you react to keeps growing, the problem is rarely the foods. It's usually the gut, the enzymes that break them down, or hormones. Treat that, and foods come back.

Does this sound like you?
If several of these are familiar, you're in the right place.
Reacting to more foods every year
Flushing or itching after eating
Headaches after wine, cheese or leftovers
Hives
Bloating or diarrhoea after meals
Worse around ovulation or before your period
A blocked nose after meals
Why intolerances multiply
A low-histamine or elimination diet is a tool to calm symptoms, not a cure.
Low DAO enzyme
DAO breaks down histamine from food, and it's made in the gut lining.
Gut damage
Dysbiosis, SIBO and a leaky gut reduce what the gut can tolerate.
Oestrogen
Oestrogen and histamine boost each other, which is why symptoms follow the cycle.
Lactose and other sugars
Some carbohydrates are poorly absorbed and ferment.
How I find the cause
Every assessment is personal. I start with your story and the results you already have, and only add what will change the plan.
Your full story
Symptoms, history, medication and everything you've already tried.
Your existing results
I go through any recent results you bring, in detail.
Testing only when it changes the plan
No standard package. If more information is needed, I'll explain why.
Alongside your doctor
Medical causes are ruled out first, with your doctor when needed.
How we treat it
Over four months, with a consultation roughly every month and the plan adjusted as you improve.
1
Calm symptoms
A short, structured low-histamine or elimination phase.
2
Find the cause
Gut, enzymes, hormones or a specific sugar.
3
Treat it
Repair the gut and support DAO and nutrient levels.
4
Reintroduce
Bring foods back one by one, with a clear plan.
