IBS. Small surface, honest scope.

Nine IBS-specific symptoms, nineteen food trigger tags from the common-culprit list, eleven everyday triggers, two episode templates, four pinned labs, and the cycle on one screen. The hub today is small. The page also names every thing we'd like to ship and haven't.

The condition

A functional GI disorder defined by patterns, not pathology.

Irritable Bowel Syndrome is one of the most common conditions seen in primary care — roughly 10 to 15% of adults globally — and one of the most under-understood. It's a functional disorder, meaning the symptoms are real but the gut looks structurally normal on a scope. Recurrent abdominal pain paired with changes in stool frequency or form, sustained over months, is the working pattern clinicians look for.

Management runs on patterns: which foods, what the cycle phase is, how stressed the week has been, what the last seven days actually looked like. Leo's job is to capture those patterns honestly — not to classify your subtype, not to design your diet, not to recommend a medication.

The symptom set

Nine IBS-specific symptoms, each with severity and notes.

The IBS pack pre-loads nine symptoms so you're not scrolling a generic library. Each entry captures severity (1–10) and an optional note. The hub keeps a rolling 90-day window so you can see recent patterns without scrolling forever.

Bloating
Gas / flatulence
Diarrhea
Constipation

Incomplete evacuation
Nausea
Heartburn / reflux
Triggers & food tags

Eleven everyday triggers and nineteen food tags from the common-culprit list.

Trigger tags get attached to each symptom log. The hub aggregates them across the last 90 days and ranks your top food triggers by frequency. The food list pulls from the foods most often discussed in IBS clinics — not a FODMAP classifier, just the common-culprit list.

Common triggers
Stress
Anxiety
Large meal
Fatty food
Spicy food
Skipped meal
Irregular meal time
Travel
Poor sleep
Menstrual cycle
Illness
Food trigger tags
Garlic
Onion
Wheat
Dairy
Lactose
Fructose
Beans / lentils
Cauliflower
Broccoli
Apple
Pear
Watermelon
Mushroom
Artificial sweetener
Carbonated drinks
Coffee
Alcohol
Spicy food
Fatty / fried food
Many of these foods overlap with the FODMAP list — Leo doesn't implement a structured FODMAP elimination-and-reintroduction protocol today (that's on the backlog). Tagging your own foods and reading the frequency back is what's available now.
Episode templates

Two pre-filled flare types, so the field-work takes ten seconds.

Two episode templates let you start a flare-log with the right symptoms already selected — useful when you're mid-flare and don't have the patience to scroll a checklist.

IBS flare-up

Pre-fills abdominal pain + bloating + gas. One tap to start the log; severity and duration on resolve.

Food reaction

Pre-fills abdominal pain + bloating + nausea — useful when a meal noticeably tipped you over.

The hub

Four cards. Four labs pinned.

Open the hub and the dashboard is a single readable surface — no premium tab, no buried feature.

Overview

Episode count this month, average severity, flare count — across the 90-day window.

Food triggers

Frequency-ranked breakdown of your tagged food triggers from the last 90 days.

Recent symptoms

Last few symptoms logged, severity color-coded.

Cycle phase

If you track a cycle, current phase is shown — IBS frequently flares around menstruation.

Labs pinned to the IBS pack: CBC · CMP · Inflammatory markers · Thyroid. The basic IBS rule-out workup. Out-of-range values are flagged.

What it isn't

The list of things we'd like to ship, and haven't yet.

The IBS hub is intentionally small today — symptoms, triggers, food tags, episodes, labs. The list below is what it doesn't do yet. Every item is on the feature-parity tracker, and the page updates as items ship.

◦ Not yet
Bristol stool scale logging in the IBS hub

Coming soon. The Bristol-scale bowel-movement logger lives in the Crohn's hub today — the IBS hub uses the symptom log only (diarrhea, constipation, urgency, incomplete evacuation as severity-rated tags). A native Bristol-scale BM logger inside the IBS hub is on the list.

◦ Not yet
IBS subtype classification (IBS-C / IBS-D / IBS-M / IBS-U / PI-IBS)

The subtypes are real and clinically useful. Leo doesn't auto-classify — the page used to imply we did, and that was wrong.

◦ Not yet
Food-reaction timing with delayed-effect window

Today food tags are attached at log time; capturing the meal-to-symptom window (30 min, 2 hr, 24 hr, next day) is a worthwhile add.

◦ Not yet
Stress-gut correlation surface

Stress is one of the eleven trigger tags today; a dedicated daily-stress rating overlay with gut symptoms is on the list.

◦ Not yet
IBS-specific PDF report card

Symptom heatmap, top triggers, Bristol distribution (when shipped), and treatment-response summary as one shareable doc. Not yet.

◦ Not yet
IBS medication shelf

Antispasmodics, fiber, prescription medications — these can be logged in the general medications surface today; a curated IBS shelf isn't built.

◦ Not yet
SIBO overlap surface

SIBO and IBS overlap clinically; Leo doesn't yet have SIBO-specific tracking.

Leo does not diagnose IBS, doesn't classify your subtype, and doesn't recommend medications or diet protocols. The hub describes what you've logged. Diagnostic and treatment decisions belong with your gastroenterologist.
