Living with Reflux (GERD)
Take care of your reflux.
Sam keeps your reflux episodes, meals and sleep in one place. You take the history to your next appointment.
Step by step: where reflux plays out, how swallowing works without reflux disease, what changes with it and where it is felt. The model shows the esophagus and the stomach with a cut-out of the diaphragm.
The esophagus
The esophagus runs from the throat, behind the windpipe and the heart, down to the stomach. Just before the stomach, it passes through a narrow gap in the diaphragm.
Esophagus / Stomach / Diaphragm (cut-out)
A simplified human figure, seen from the front at an angle. The view moves towards the chest and upper abdomen, where the esophagus and the stomach turn orange. A cut-out of the diaphragm, the windpipe and the heart stay grey.
Swallowing
After a swallow, a muscle wave pushes food down. At the lower end, a ring muscle opens to let it into the stomach, then closes again, supported by the diaphragm.
Lower esophageal sphincter, approximate / Swallowed food / Diaphragm (cut-out)
Closer view of the esophagus and the stomach in orange, with the diaphragm cut-out in grey. A white band and a few white dots travel down the esophagus into the stomach. The ring muscle at the lower end sits at the level of the diaphragm.
In reflux disease
Occasional backflow of stomach contents is common, for example after a large meal. It counts as reflux disease when it causes troublesome symptoms such as heartburn or regurgitation. A main reason: the stomach entrance closes less reliably.

Open, backflow
Backflow
Same view, slightly closer to the junction. A darker orange band and small dots rise from the stomach a short way into the lower esophagus, a schematic picture of backflow. The wall of the esophagus itself does not change. A sketch compares the junction closed and open.
Day to day
Heartburn is a burning feeling behind the breastbone that can rise toward the neck. Stomach contents can also come back up toward the mouth, often with a sour or bitter taste. Symptoms can increase when bending over or lying down.
Worth discussing with your doctor.
New or severe symptoms need a doctor. Chest pain, fainting or sudden breathlessness: call emergency services. Chest pain can also be a heart problem.
Behind the breastbone / Throat
The view pulls back to the whole figure and the organs return to grey. Two soft orange areas on the body surface mark the area behind the breastbone and the front of the neck.
Own simplified illustration based on the sources above.
The model shows the esophagus, the stomach and a cut-out of the diaphragm around the point where the esophagus passes through; the opening itself is not modelled. The windpipe, the heart wall and the duodenum are there for orientation. The lower esophageal sphincter is not a separate structure in the model, so its position is approximate. The white dots in the swallow step stand for food moving down; backflow is drawn as a band with dots, and its height and amount are schematic. The soft areas over the breastbone and the throat mark where symptoms are felt. Hiatal hernia and changes to the lining are not shown. Adult male reference model; close-ups and the sketch are not to scale.
What Sam keeps for you
For people living with reflux (GERD) who want a record for their appointments. Sam is not a medical device. It keeps what you and your wearable already produce and puts it in one place.
Once you've logged 5 or more episodes, Sam shows a trigger map of your food and circumstance tags side by side, making patterns easier to spot. It's not a verdict on any food, just a mirror of what you've logged.
Sam reminds you to take your prescribed acid-suppressant medication, defaulting to 7:30 am, before your first meal of the day. You can adjust the time to match your own routine.
When heartburn, regurgitation, chest discomfort, cough, or throat irritation comes on, you log the symptom type and how severe it was. You can also note what you ate, the circumstances, whether it happened at night, and how well your medication worked.
Once a month, Sam walks you through the GERD-HRQL (Velanovich) questionnaire, a validated 10-item quality-of-life questionnaire, to see how reflux has been affecting you.
If you log chest discomfort that could signal a cardiac issue, Sam points you straight to emergency services.
All of it can go into one doctor report as a PDF for your appointment.
Every Medical Program has its own doctor report as a PDF. You choose the period it covers and can share the report.

Stomach acid and reflux episodes are outside what a smartwatch can record. Sam keeps the rest.
Doctor report (PDF)
Sam puts your reflux diary together as a PDF for your GP or gastroenterologist. You choose the period the visit should cover: 1, 3, 6 or 12 months, or the whole record.

GERD (gastroesophageal reflux disease) is a condition in which stomach acid regularly flows back into the esophagus, causing troublesome symptoms like heartburn or regurgitation. Most people experience occasional reflux, but GERD involves frequent or disruptive episodes. Only a gastroenterologist can diagnose GERD through clinical assessment or testing (such as pH monitoring or endoscopy); Sam cannot perform that diagnosis.
Common triggers include eating large or fatty meals, eating close to bedtime, lying down shortly after eating, obesity, alcohol, caffeine, smoking, and certain medications. Triggers differ from person to person. In Sam you can tag foods and circumstances on each logged episode and see your own counts, next to your sleep and alcohol days.
Guidelines list lifestyle changes as a first step: elevating the head of the bed, avoiding meals 2-3 hours before lying down, avoiding personal trigger foods, weight management if relevant, and reducing alcohol and caffeine. Whether medication is needed depends on your individual case and should be discussed with a gastroenterologist or your primary care doctor.
GERD rarely causes serious complications in most people. Untreated cases can occasionally progress to erosion of the esophageal lining, strictures, or Barrett's esophagus, especially in severe cases or when other factors are present. Talk to a gastroenterologist if symptoms persist, worsen, or significantly disrupt your life. Your doctor can rule out complications and plan appropriate long-term management.
No. No consumer wearable, including those paired with Sam, can measure stomach acid levels or pH. Sam cannot automatically detect or predict heartburn episodes; these depend on your own awareness and logging. What Sam does do is show your sleep, alcohol days and weight alongside your logged episodes, so you and your doctor can look at them together.
A diary linking foods and meal times to heartburn episodes is a standard tool clinicians use to identify your personal triggers. In Sam's reflux episode log you record each episode with food tags, circumstance tags and whether it happened at night. After 5 or more logged episodes Sam shows how often each tag occurs, not a verdict on any food.
Yes. You log each episode yourself - symptom, severity, what you ate, the circumstances and whether it happened at night. Sam shows sleep quality, alcohol days and weight beside it, which is the context your clinician would otherwise have to ask you to recall.
