Why a diary helps with IBS

Complaints trail their trigger. Lunch shows up in the evening, dinner the next morning – memory alone rarely finds the connection.

A food and symptom diary puts meals and complaints side by side with their times. It is also the first thing a gastroenterologist or GP asks for when IBS or a food intolerance is suspected.

Frequently asked questions

What belongs in an IBS food diary?

Meals, bowel movements and symptoms, each with its time. One sentence is enough for a meal – by voice, photo, barcode or text. Stool goes in on the Bristol stool scale, plus the sensations from the Rome IV criteria: urgency, straining, cramping, burning, incomplete evacuation. Sleep and movement come in from Apple Health or Health Connect.

Are FODMAPs and histamine included?

Yes. Every meal's nutrients include all five FODMAP groups – fructans, galacto-oligosaccharides, lactose, excess fructose and polyols – and histamine, and they feed into the explanations. NutriSpy is not a Monash-style elimination program.

What does NutriSpy make of my entries?

After five logged days, NutriSpy explains your symptoms from your own data: which habits and foods go with your better and worse days. After ten days with bowel-movement entries, the explanation of your stool pattern follows. Every pattern comes with a read on how well it holds up – a hunch stays a hunch. Missing days are treated as missing, not guessed.

What do I bring to my doctor?

Pick a date range and the categories – meals, bowel movements, symptoms, sleep – and export your diary as PDF or CSV. Two weeks with times, Bristol types and symptom intensities is more than most patients bring. The export is part of Premium.

Does it work without a wearable?

Yes. Meals, bowel movements and symptoms are yours to log – by voice, photo, barcode or text. Sleep and activity can come in from Apple Health or Health Connect, or in one spoken sentence.

Does a food diary replace a diagnosis?

No. A diary shows what goes together in your own data – it does not diagnose. NutriSpy never names a condition. IBS, intolerances and other causes are for your doctor to work out; the diary is the basis for that conversation.

What does NutriSpy cost?

Your diary is free. AI-powered logging is part of Premium, with a few free entries each month. The insights, the sync into Apple Health or Health Connect and the export are part of Premium, by subscription. Current prices are shown in the app.
