Why Healing Reactions Are a Good Sign (and When They’re Not)

You start a new approach to support your gut, and instead of feeling better you briefly feel worse — more tired, a bit headachy, off. You may have heard this called a "healing reaction" or "die-off," and that it means things are working. Sometimes that's true. Sometimes it isn't. Knowing the difference genuinely matters, so let's be honest about both sides.

What people mean by a "healing reaction"

The idea is that when you start addressing an imbalance — shifting the microbiome, for instance — there can be a short, temporary period of feeling off as your body adjusts. Mild, brief, and self-resolving symptoms can sometimes accompany a real change in the right direction.

Why a little discomfort can be normal

When the internal environment changes, your body adapts — and adaptation isn't always perfectly smooth. Mild, short-lived symptoms that settle within a few days, while your overall trajectory is still upward, can be a normal part of adjustment. The key words are mild, short-lived, and improving overall.

The important caveat — when it's NOT just a healing reaction

Here's where "it's just die-off, push through" becomes genuinely risky advice. Worsening symptoms are not always a good sign — sometimes they mean an approach is too aggressive, isn't right for you, or that something needs medical attention. Treating every bad reaction as proof it's "working" can lead people to push through things they shouldn't.

Take it seriously — and seek medical advice — if symptoms are severe, getting worse rather than better, lasting beyond a few days, or include anything alarming (significant pain, fever, breathing issues, severe digestive symptoms, or signs of an allergic reaction). When in doubt, stop and check with a professional. No protocol is worth ignoring a real warning sign.

Why "push through" is poor blanket advice

The wellness world loves the "you have to feel worse to feel better" narrative, because it conveniently explains away any negative reaction. But your body's signals exist for a reason. A good approach is gentle enough that you rarely need to white-knuckle through it — and it's adjusted when you don't tolerate something, not forced.

A measured way to think about it

Real, lasting change is usually gradual and reasonably tolerable, not a dramatic ordeal. Feeling slightly off briefly while otherwise improving can be fine. Feeling significantly worse, or worse for long, is a signal to pause and reassess with support — ideally working with someone who adjusts the approach to you, alongside your doctor.

Frequently asked questions

Is feeling worse a sign that a gut protocol is working?
Sometimes mild, brief symptoms can accompany a positive change — but worsening symptoms can also mean an approach is too aggressive or not right for you. It's not automatically a good sign.

How do I know if it's a healing reaction or a warning?
A normal adjustment is mild, short-lived and improving overall. Severe, worsening, prolonged, or alarming symptoms are a signal to stop and seek medical advice.

Should I push through if I feel bad?
Not as a rule. "Push through" is poor blanket advice — your body's signals matter. A good approach is gentle enough that you rarely need to force it.

Can I work with you online if I'm not in Lisbon?
Yes. I support clients online in English, Portuguese, Spanish and French, as well as in person in Lisbon and Estoril.
