Before a Gastric Emptying Test: What to Log

Updated 29 Oct 2026

A gastric emptying test may be booked weeks ahead. That waiting time can be put to use: the test measures one meal on one day, while your notes show how the weeks around it really went.

This guide explains what to log before a gastric emptying test: the test details and instructions, daily symptom scores, a full medicine list, your health history, and the test day itself.

Why log before a gastric emptying test

The NIDDK notes that doctors diagnose gastroparesis based on your medical history, a physical exam, your symptoms, and medical tests (NIDDK). The test is one part. Your history and symptoms are the others, and they are the parts you can prepare.

The NIDDK also notes doctors may use tests to look for complications and to rule out other health problems that may be causing your symptoms (NIDDK). A clear record of what you feel, when, and after which meals helps your doctor decide what the result means for you.

Symptoms also blur over weeks. A dated record is more reliable than describing the last month from memory in a few minutes. A short entry each evening is enough.

In Gastroparesis Journey, the Daily check-in keeps the same fields every day, so the weeks before the test read as one sequence.

How to record the test details and instructions

The NIDDK describes three tests to measure stomach emptying: a gastric emptying scan, where you eat a bland meal such as eggs or an egg substitute with a small amount of radioactive material; a breath test, where breath samples are collected after a meal; and a wireless motility capsule that you swallow (NIDDK).

Write down which test you are having, the date and time, and where. The NIDDK notes the scan usually takes about 4 hours, and the breath test usually about 4 hours too (NIDDK), so plan the day around that.

Write every instruction you receive word for word: what to eat or avoid beforehand, how long to fast, and whether any medicine should be paused. If anything is unclear, ask the team that booked the test, and note the answer with the date.

In Gastroparesis Journey, the Daily Journal holds the test details and instructions in one entry.

Which symptoms to score before the test

The NIDDK lists symptoms of gastroparesis that may include feeling full soon after starting a meal, feeling full long after eating a meal, nausea, vomiting, too much bloating, too much belching, pain in your upper abdomen, heartburn, and poor appetite (NIDDK).

Each evening, rate fullness, nausea, bloating, and upper abdominal pain on a 0 to 10 scale. Note any vomiting with the time and how long after a meal it happened.

Add a short meal note: what you ate and roughly how much. Over two or three weeks, this shows which meals sat badly and which were easier, which is useful beside a test that measures a single meal.

For more on meal notes, see early satiety meal notes.

In Gastroparesis Journey, the Food Tracker holds meals and the Daily check-in holds the scores.

How to make a full medicine list

The NIDDK advises telling your doctor about all prescription medicines, over-the-counter medicines, and dietary supplements you are taking (NIDDK). It also notes that certain medicines may delay gastric emptying or affect motility, including narcotic pain medicines, some antidepressants, some anticholinergics, some medicines used to treat overactive bladder, and pramlintide (NIDDK).

List each medicine with its dose, when you take it, and when you started. Include anything taken only now and then, such as a pain reliever or an anti-nausea medicine. Add supplements and herbal products by name, and note any medicine you stopped in the past few months, with the date and the reason.

Do not stop any medicine on your own. Ask whether any should change before the test, and write the answer down.

In Gastroparesis Journey, My Meds keeps each medicine with its dose and start date.

Which health history to bring

The NIDDK notes your doctor will ask about current and past health problems such as diabetes, scleroderma, nervous system disorders, and hypothyroidism, whether you have had surgery on your esophagus, stomach, or small intestine, and whether you have had radiation therapy on your chest or stomach area (NIDDK).

Write a short page: each condition with the year it was diagnosed, each surgery with its date, and any radiation therapy. Add when your stomach symptoms began and anything that happened around then, such as a stomach infection.

If your story has been long, see how to rebuild the story for the next visit.

If you live with diabetes, bring your recent glucose notes as well, with the dates they cover.

In Gastroparesis Journey, My Labs holds earlier results with their dates.

What to log on the test day and after

On the day, write what you ate and when, whether you followed every instruction, and how you felt before the test. Note anything unusual, such as vomiting during the test or a very bad symptom day.

For the next few days, keep your scores going as usual. When the result arrives, write it down with the date and what your doctor said it means. Then look back: did the result fit how the weeks before it felt?

The NIDDK advises seeking a doctor's help right away for signs such as severe pain or cramping in your abdomen, vomiting for more than an hour, or feeling extremely weak or fainting (NIDDK). Do not wait for a test date if these happen.

While you wait, see what to track while waiting for the specialist.

How Gastroparesis Journey can help

A notebook can hold a test date. The harder part is keeping meals, symptoms, medicines, and history in one sequence a care team can read in a minute.

Gastroparesis Journey is a personal gastroparesis tracker from Health Journey Labs on the App Store and Google Play. It records meals, symptoms, medicines, and weight in one dated history, and its insights show which meals and habits come before easier or harder days. Learn explains the condition in plain words, and the AI companions, such as Clara, answer questions when a new symptom or result is hard to read. Below is what you can use and how each part helps:

• Daily check-in — A short guided pass across symptoms, mood, nutrition, sleep, exercise, meds, and external factors, including nausea, fullness, vomiting, and bloating, so links you would not remember on your own show up side by side.
• Daily Journal — Freer notes, including voice when nausea makes typing hard, that add detail a score alone cannot show.
• Flare Tracker — Mark a day clearly worse than usual, so you can tell a one-off bad day from a repeating pattern.
• My Meds — Medicine names and timing, so you can line up a start date or dose change with symptom days.
• My Labs — Result dates for emptying studies, blood work, HbA1c, and other tests, so each result sits next to how you felt that month.
• Weekly Goals — Set one small aim, such as smaller dinners or a walk after meals, and see whether it held and whether symptoms changed.
• Learn — Short education topics on gastroparesis themes such as meal size, texture, hydration, and visit preparation.
• AI companions — Clara and specialist companions, including nutrition, already see your logged history, which helps with meal ideas or visit wording.
• My Care Team — A profile for each clinician, plus upcoming appointments and notes for each visit, used before, during, and after appointments.
• Doctor Report — Two views: the Appointment Planning Report helps you prepare what to ask, and Generate Report, opened from a saved doctor, builds a dated summary of your recent progress for that doctor.
• My Assessments — Structured check-ins that add context about you across weeks.
• Food Tracker — Meal and drink lines with size and texture, so you can line up meals with fullness and nausea.
• Period Tracker — Cycle dates, so you can see whether symptom days cluster at a certain point in the cycle.
• Weight Tracker — Weekly weights, so a downward trend shows up early against symptom weeks.
• Stool Tracker — Bowel movements with color, urgency, blood, pain, and related symptoms, so you can line up bowel changes with meals and symptom days.

Everything you log builds one history. Guided forms include the key questions, and you can add custom symptoms when you need your own labels. Gastroparesis Journey is free to download.
