Gastroparesis. With or without the device.
Two kinds of gastroparesis patients use Leo: the ones who manage with diet and medication, and the ones with a gastric electrical stimulator who need to track their device adjustments alongside their symptoms. The hub serves both — same GCSI diary, same food log, the device track folded in only if it's yours.
Delayed gastric emptying, without an obstruction.
Gastroparesis is delayed stomach emptying in the absence of a mechanical blockage. It looks like nausea, vomiting, early satiety, post-meal fullness, bloating, and upper abdominal pain — usually some combination of those, in patterns that change from meal to meal. The two most common causes are diabetic gastroparesis and idiopathic gastroparesis; post-surgical and connective-tissue-disease-related forms exist too.
Management splits roughly into three layers — dietary adjustments (smaller meals, lower fat and fiber, liquid nutrition when needed), prokinetic and anti-emetic medications, and for refractory patients, a gastric electrical stimulator. The hub is designed to surface what's relevant to you: if you don't have a device, the device sections stay hidden.
The validated 12-item GCSI, on your phone.
The Gastroparesis Cardinal Symptom Index — GCSI — is the standard daily symptom scale your gastroenterologist learned in fellowship. It's twelve items across three subscales, rated 0 to 5 (None / Very Mild / Mild / Moderate / Severe / Very Severe). Leo's diary takes about a minute and a half to fill out. Subscale means and the total score (the average of the three subscale means) compute live as you log.
- ·Nausea
- ·Vomiting
- ·Early satiety
- ·Postprandial fullness
- ·Loss of appetite
- ·Excessively full
- ·Bloating
- ·Stomach visibly larger
- ·Upper abdominal pain
- ·Reflux / heartburn
- ·Constipation
- ·Diarrhea
Log a meal. Get a reminder. Capture when symptoms hit.
For gastroparesis, the gap between bite and symptom matters. Leo's food log is purpose-built for that. When you log a meal, you choose a follow-up reminder — 15, 30, 45, or 60 minutes. When the reminder fires, you tap one of five buckets:
Then a 0–10 severity slider, a checklist of sixteen gastroparesis-specific symptoms (nausea, vomiting, bloating, fullness, reflux, upper-abdominal pain, etc.), and an optional note. “No symptoms” is also one of the buckets — and just as valuable as a positive entry.
For folks with a stimulator: profile, adjustment log, and history.
If you have a gastric electrical stimulator, three surfaces unlock. First, a full device profile:
Second, an adjustment log. After every settings visit, you log:
Five chart views, all built around the same data.
Charts open as a tabbed surface so you can flip between views without losing context. Each chart marks adjustment dates with a red vertical line so visit-to-visit changes are easy to spot.
Single-line trend of your daily total over 30 / 90 / 180 / 365 days. Adjustment dates are marked as red dashed verticals so you can see when settings changed.
Three lines on one chart — nausea, fullness, bloating — color-coded. Reveals which subscale is driving your score.
Pick any of the 12 symptoms and chart just that one. Useful for isolating a single trigger or a single response to a med change.
Pick a device parameter (amplitude, pulse width, frequency, cycling, impedance, voltage); see every adjustment plotted on a timeline.
Plot a symptom score and a device setting on the same timeline. A visual overlay — labeled "scales may differ" — not a Pearson coefficient. It's pattern-spotting, not statistics.
One screen. Offline. Built for a triage nurse who's never seen one of these.
Most ER staff have never seen a gastric stimulator. The ER Quick-Share card is a single screen, cached locally, that works without internet. It carries everything someone needs to triage you safely:
The list of things we'd like to ship, and haven't yet.
The gastroparesis hub is one of the deeper condition surfaces in Leo, but it's not complete. This is the active backlog — every item is on the feature-parity tracker, and the page updates as items ship.
Today the correlation chart is a visual overlay only — "scales may differ." A real Pearson coefficient with a confidence note is a worthwhile add.
The code path is written but currently disabled. Will land soon — useful when sharing across rooms or shifts.
Today the ER card and history can be shared via system share-sheet as text. A doctor-formatted PDF and a one-tap secure share to a clinic portal aren't built yet.
Mentioned in journal templates but not a standalone tracking surface.
TPN exists as a hydration intake type elsewhere in Leo; a gastroparesis-specific TPN ledger with prescribed volume/cycle isn't in the hub yet.
If you've had a GES, the result lives in your medical records — Leo doesn't yet have a structured field for it. Coming.
Reglan / Domperidone / Erythromycin can be logged in the general medications list; a curated gastroparesis-meds surface with onset times and contraindications is on the list.
Today battery is a five-state dropdown. Percentage and an automatic replacement-window flag would be better.
GCSI diary, food-to-symptom timeline, device-aware when it's yours.
The validated 12-item GCSI, a food log built around the gap between bite and symptom, a five-chart shelf, and an offline ER card for the night a triage nurse hasn't seen a stimulator before.
