What is in it
Every chapter corresponds to an explainer on this site, re-edited for reading offline, with its full source list. Nothing in the handbook recommends a supplement, product or diet.
- Psoriasis Why psoriasis comes back in the same spot
- IBS Why IBS hits minutes after a meal, when the food is still in your stomach
- Tracking What a symptom log can tell you, and what it cannot
- IBS Why a stomach bug can leave a years-long footprint in the gut
- Eczema Does bad air make eczema flare? What the AQI can and cannot tell you
- Eczema · Psoriasis The gut-skin axis is real. 'Your skin disease starts in your gut' is not what it shows.
- Psoriasis Why a scratch can turn into a psoriasis plaque, and why most scratches don't
- IBS Why the same food can hurt on Tuesday and not on Friday
- Eczema Why a workout makes eczema itch, and why the sweat itself is not the villain
- Eczema Hard water and eczema: what happened when 336 families got water softeners
Who it is for
People living with a flaring condition who want the honest version of what the research says, and clinicians who want a patient-facing summary that will not oversell. It is education, not a treatment plan.
