When food sensitivities go undiagnosed and what happens after
For a long time, I told myself I was coping. I had two young children. I was working. I was functioning. I still met friends for dinner, even if I knew I would barely sleep afterwards. From the outside, nothing dramatic had collapsed. And yet my body was falling apart. Aching joints and muscles, swollen lymph glands, weight gain, strange neurological symptoms no one could explain, insomnia that made the nights feel endless. I would lie awake drained by exhaustion yet unable to drop into sleep, dreading what the next day would feel like.
What made it worse was not knowing. Every medical appointment ended with similar evasive answers: your tests are normal. You have a virus. You're stressed. I started to question my sanity, if nothing shows up, maybe this is just how life feels now. Maybe it's motherhood and I am just not as resilient as others. But the more plausible explanation was that there was seriously something wrong with me which the medical profession failed to diagnose.
When I eventually found an allergy specialist who diagnosed that my immune system was reacting to almost everything I was eating, the initial relief was immense. There was finally an explanation. I was not mad, and I was not weak. I thought that would be the turning point. If that period of not knowing sounds familiar, there is more about the years before diagnosis in I Thought My Body Had Turned Against Me.
In some ways it was as physically things began to improve. But what I had not anticipated was how much my life would need to reorganise itself around food. Eating stopped being instinctive and easy, it became deliberate, planned, and structured. Eating away from home required preparation, restaurants were a challenge, Christmas and birthdays were depressing. Every ingredient list demanded scrutiny. Physical improvements came with restriction, and restriction came with a sense of loss.
I remember thinking more than once: if this is what it takes to get well, it feels like a high price to pay. I was better physically, but I was not at ease. That is when the question began to surface, though I did not phrase it so clearly at the time: is this surviving, or is this living?
Because surviving was doable. I had been surviving for years on a few hours sleep, in pain. Pushing through, overriding fatigue, ignoring fear, carrying on regardless. But living felt different, it implied some degree of ease, fun, and a feeling that my body and I were on the same side.
The medical explanation and dietary adjustments helped. But what took a lot longer was something less visible: adjusting emotionally and practically to this new reality. Learning that progress is not linear and that a flare does not mean failure. Learning to stop scanning my body every hour for signs of regression. No one had prepared me for that part.
We talk about diagnosis, elimination diets, supplements and protocols. We do not talk nearly enough about the psychological shift that accompanies food sensitivities — the slow integration of a new way of living.
Looking back, I can see that what I needed was not just a treatment plan. I needed steadiness, context, and reassurance that this adjustment phase was not permanent. It would get easier, even natural, eventually, the way it does when you learn any new skill. That realisation is what Nurture & Thrive grew out of, and it is also what shaped the Food Sensitivities Support System — a practical and emotional framework for managing this day to day, rather than just surviving it. If you are not ready for that yet, the free resources are a good place to start, including A Map for Living with Food Sensitivities, which puts the adjustment process into context.
Not everyone's path will look like mine and I do not have a miracle answer. But I know how destabilising it is to move from "something is wrong" to "food is part of the reason" and then discover that the diagnosis is only the beginning.
If you are in that space, where you have identified the problem but have not yet found your footing, I understand how disorienting it can be. You are not doing it badly and you are not weak for finding it hard. You are adjusting to something that reaches into your everyday life in ways few other conditions do.
The shift from surviving to living does not happen overnight. But it does happen gradually through repetition and integration rather than force. That, more than anything else, is why I do this work.
