What Your Bloating Pattern Tells You About the Cause, And Why Food Elimination Often Fails
You have tried cutting out gluten. Then dairy. Then onion and garlic. Then most fruit. You are eating the same small rotation of foods and you are still bloated. The list of things you can eat keeps shrinking without the bloating actually going away, and you have started to wonder if food is somehow the problem no matter what you eat. The food is almost never the entire problem. Bloating is a symptom produced by fermentation in the gut, and when the wrong bacteria are in the


Period Pain: Why It Happens and What You Can Do About It Beyond Pain Relief
You have been told that period pain is normal for women. So you've managed it with pain relief medication every month, and tried to push through. And you've accepted this as just how your cycles are, because the person who told you it was normal was a doctor, and there did not seem to be much else to say about it. Period pain is extremely common. But common and normal are not the same thing, and pain that significantly affects your ability to function every cycle is not somet


Persistent Iron Deficiency: Why Your Iron Won't Stay Up and What to Do About It
You've been taking iron and your levels have come up a little. Then you stopped and they dropped back down. Or you had an infusion, felt better for a few months, and then the familiar heaviness and brain fog slowly returned. So you've been told to keep supplementing, but nobody has asked why this keeps happening. Persistent iron deficiency, iron that will not come up and stay up despite appropriate treatment, is one of the most common clinical presentations in women of reprod


PCOS: Why Knowing Your Subtype Changes Everything About Treatment
If you have been diagnosed with PCOS and told to go on the pill, lose weight, and come back when you want to get pregnant, you have received a diagnosis without an explanation. PCOS, polycystic ovary syndrome, affects one in eight women worldwide. It is the most common hormonal condition in women of reproductive age and the leading cause of anovulatory infertility. And yet the way it is routinely managed, with generic advice rather than investigation into what is actually dri


Thyroid Health: Why a Normal TSH Doesn't Always Mean Your Thyroid Is Working Well
Your TSH is normal. Your medication dose has been reviewed and confirmed. By every measure your doctor is using, your thyroid is being managed correctly. But you are still exhausted by mid-morning. Still cold when everyone around you is comfortable. Still losing more hair than you should be. Still not feeling great, in ways you struggle to explain to people who ask if you are feeling better now that your thyroid is being treated. This is one of the most consistent and one of


Heavy Periods Without Surgery or Medication: Understanding the Causes and What You Can Do
If you have heavy periods and you have been offered the Mirena IUD, an ablation, or long-term hormonal medication, and none of those options feel right to you, I want you to know that you're not out of options. The options you have been offered are legitimate treatments that work well for many women. But they are not the only path, and for a significant number of women, they are not the right first step. One of my concerns is that they address the bleeding without addressing


Recurrent Thrush: Why It Keeps Coming Back and What Your Vaginal Microbiome Has to Do With It
You know the cycle. The itching starts, you recognise it immediately because you have done this before, you go to the chemist, you get the same cream or tablet, it clears up within a few days, and you go on with your life. Until a few weeks or months later, it happens again. If you have had this experience more than four times in a year, you are dealing with what is clinically termed recurrent vulvovaginal candidiasis. You have been treated for the yeast infection, repeatedly


Gilbert's Syndrome: Why Benign Does Not Mean Without Consequence
You had a blood test. Your bilirubin came back mildly elevated. The result was flagged, and you were told it was Gilbert's syndrome. Nothing to worry about. No treatment required. A benign condition. And then you went home and kept putting up with the nausea that comes and goes without explanation. The fatigue that descends sometimes for days. The periods that are heavier than they should be. The mood that shifts in the second half of your cycle and turns into intense anxiety


PMDD and Histamine: Is There a Connection?
For about ten days every month, everything feels pointless. Not sad, not stressed, just a flat, heavy, hopeless version of yourself that cannot be explained by anything happening in your life. You parent through it, work through it, hold yourself together on the outside while barely surviving the inside. And then your period arrives, and within hours or a day or two, you feel like yourself again. If this sounds familiar, what you are describing is not a personality trait, not


Why Am I Spotting Before My Period? What Brown Discharge Before Your Period Actually Means
If you have been managing brown spotting or discharge in the days before your period starts, you have probably been told one of two things. Either that it is normal, or that it is nothing to worry about. Neither of those answers is quite right. Spotting before your period is extremely common. But common and normal are not the same thing. And there is something important sitting behind that spotting that most women, and many practitioners, never connect to the wider picture of


Endometriosis and Gut Health: Why Your Gut Symptoms Are Not a Separate Problem
If you have endometriosis and you also have ongoing gut symptoms, you have probably been managing them as two separate conditions. Two different doctors, two different conversations, two different management plans that never quite intersect. But the research is increasingly clear that your gut and your endometriosis are not separate problems. They are part of the same picture. And treating them in isolation is one of the reasons so many women with endometriosis continue to st


The Preconception Window: Why the Three Months Before Pregnancy Matter More Than You Think
Most people think about pregnancy health as something that starts when the test comes back positive. You get the result, you book a GP appointment, you start taking prenatal vitamins, you read the books. But there is a window of time before pregnancy that has a profound and lasting influence on whether you conceive, how your pregnancy unfolds, and the long-term health of the child you are growing. And most people have no idea it exists. It is called the preconception window.


Hysterectomy - How it Can Influence your Long Term Health
If you have been offered a hysterectomy for heavy periods, chronic pelvic pain, fibroids, or any other gynaecological diagnosis, the focus of conversations with your doctor have probably been about symptom improvement. But there is a growing body of research on the long term implications of this surgery that rarely makes it into the appointment where the decision is being made. This information is really important to know before you say yes to something irreversible, so you a


Your Period Pain Is Not Normal. And the Fact That Nobody Told You That Is a Problem.
In 2026, women are still leaving doctors' appointments with a prescription and a shrug. We've been told our symptoms are manageable, inevitable, or best addressed by simply switching off our cycles entirely. I think we deserve better than that, and I think the cost of accepting less is higher than most women realise. Think back to where you actually learned what periods were supposed to be like. Not the classroom diagrams; the real-life version. How heavy. How painful. How un


ADHD in Women: The Hormonal Link Nobody Is Talking About
If you have been diagnosed with ADHD as an adult, or if you are in the process of seeking answers for symptoms you have been managing alone for decades, there is something I want you to know. Your experience is real. Your difficulty is not a lack of effort or discipline. And there is a layer to this picture, particularly for women, that is rarely discussed even in clinical settings: Hormones. The relationship between female sex hormones and ADHD symptoms is one of the most si


What is SIBO? Why Bacteria in the Wrong Place Changes Everything About Your Gut
Bloating that builds through the day no matter what you eat. A food tolerance picture that keeps changing. Fatigue that sleep does not touch. Digestive discomfort that has become so normal you have stopped mentioning it to your doctor. If this sounds familiar, I want to introduce you to a condition that is far more common than most people realise, and that frequently goes undiagnosed for years. It is called SIBO. Small intestinal bacterial overgrowth. And while the name sound


HPV Positive on Cervical Screening? How the Vaginal Microbiome and Immune System Influence Clearance
Being told you’ve tested positive for HPV on a cervical screening test can be worrying. In many cases, the recommendation is to wait and repeat testing in 12 months, but this can raise questions: How did this happen? Is there anything I can do to help my body clear it? The short answer is that you didn't do anything wrong, and most HPV infections clear spontaneously. But the longer answer is more nuanced. HPV clearance depends on the immune system, the local cervical environm


Period Flu: Why You Feel Sick Before Your Period and What to Do About It
Every month, like clockwork, it happens. A few days before your period arrives you start to feel run down. Body aches you cannot explain. A heaviness and fatigue that sleep doesn't touch. Maybe a headache, hayfever, some nausea, digestive upset. You feel, in a word, terrible. And then your period starts and within a day or two you feel almost normal again. If this sounds familiar, there is a name for what you are experiencing. It is informally called period flu. And while it


Why I avoid restrictive diets (and what food intolerances may be telling you)
Most people don’t set out intending to follow a restrictive diet. It often starts with a genuine attempt to feel better. You remove gluten because you’ve heard it might help bloating. You reduce dairy because sometimes it upsets your tummy. You try low FODMAP after weeks of cramping and discomfort. Your symptoms improve, at least temporarily, and the change feels justified. Over time, another food seems to cause a reaction. Then another. The list of safe foods gets shorter an


Oestrogen Withdrawal & Migraine: Why It Happens Before Your Period
If you live with menstrual migraines, you often know they’re coming before they arrive. There’s a familiar window in the month when you brace yourself for what might unfold. For many, these migraines cluster in the days just before a period begins, sometimes with striking predictability. They’re often described as “just hormonal,” but that phrase doesn’t really do them justice. What’s actually happening is far more involved. In many cases, menstrual migraine is linked to some
