What Is Gastroparesis and Why Does It Make Eating So Difficult?
If you’ve been experiencing nausea after meals, feeling uncomfortably full after eating just a little food, or dealing with persistent bloating and stomach discomfort, you may have a condition called gastroparesis. This is a disorder where your stomach takes much longer than normal to empty food into your small intestine. Even small portions of food can trigger symptoms that leave you feeling miserable—and missing out on moments that matter with the people you love.
The symptoms can be frustrating and unpredictable: nausea, vomiting, feeling full too quickly, excessive bloating, belching, stomach pain, and general abdominal discomfort. For many people, these symptoms become worse during holiday celebrations when rich, heavy foods are abundant. The Gastric Emptying Breath Test (GEBT) can provide accurate diagnostic information in this regard.
You’re far from alone in dealing with this. According to the International Foundation for Gastrointestinal Disorders, an estimated 5 million people in the United States live with gastroparesis. While the prevalence varies depending on how strictly it’s defined, recent research shows that gastroparesis affects approximately 267 per 100,000 adults in the United States—and the symptoms impact people’s quality of life significantly.
You Don’t Have to Suffer in Silence
Here’s the most important thing we want you to know: you don’t have to keep struggling through meals and missing out on celebrations. If you’ve been dealing with these symptoms—whether for months or years—please don’t minimize what you’re going through. Your symptoms are real, they matter, and there is help available.
The first step is talking openly with your healthcare provider about what you’re experiencing. Bring a list of your symptoms, when they occur, and how they’re affecting your daily life. Don’t hold back or downplay your struggles—your doctor needs to understand the full picture to help you effectively.
Your healthcare provider can offer several diagnostic tools to determine whether gastroparesis is causing your symptoms. Once you have a clear diagnosis, treatment options are available that can genuinely improve your quality of life. According to clinical guidelines established by the American College of Gastroenterology, there are well-documented approaches to managing gastroparesis.
Treatment might include:
- Dietary modifications tailored to your specific needs and symptoms
- Better diabetes management if you have diabetes, since improving blood sugar control can help with gastric emptying
- Medications that can improve your stomach’s emptying rate and reduce symptoms like nausea
- Nutritional support to ensure you’re getting adequate calories and nutrients
Many people find significant relief once they receive proper treatment. While gastroparesis can be challenging to manage, getting an accurate diagnosis opens the door to solutions that can help you participate more fully in the moments that matter most—including holiday celebrations with loved ones.
Getting a Diagnosis: What Testing Options Are Available?
Once you and your doctor suspect gastroparesis, the next step is confirming the diagnosis through gastric emptying testing. Having objective test results not only validates what you’ve been experiencing but also helps your healthcare team develop the most effective treatment plan for you.
There are two main approaches to testing for gastroparesis:
Traditional Gastric Emptying Scintigraphy
For years, gastric emptying scintigraphy has been the standard test for gastroparesis. You would consume a meal containing a small amount of radioactive material, then lie under a special camera that tracks how quickly the meal leaves your stomach over a four-hour period.
While this test is accurate, it does have some drawbacks. You need to travel to a specially licensed nuclear medicine facility—often in a hospital or major medical center—which may not be conveniently located. The test involves exposure to a small amount of radiation. And for some people, the thought of consuming radioactive material can be anxiety-provoking, even though the amount used is considered safe.
The Gastric Emptying Breath Test (GEBT): A Newer, More Convenient Option
We’re pleased to share that there’s now a safer, more convenient alternative that’s been validated and FDA-approved since 2015. The Gastric Emptying Breath Test (GEBT) can provide the same diagnostic information as scintigraphy—but without radiation and without requiring you to travel to a specialized facility.
Here’s how GEBT works:
The test is conducted over four hours after you’ve fasted overnight (just like with scintigraphy). You’ll provide baseline breath samples, then eat a standardized test meal containing a specially prepared egg mixture, Spirulina (a blue-green algae that’s been safely used as a nutritional supplement), and saltine crackers. The Spirulina has been enriched with carbon-13—a naturally occurring, completely safe, non-radioactive form of carbon that’s already present in about 1% of all the carbon in your body and food.
After eating the meal, you provide breath samples at six specific times: 45, 90, 120, 150, 180, and 240 minutes. These samples are sent to a certified laboratory where they measure how quickly the carbon-13 appears in your breath as carbon dioxide. This measurement directly reflects how fast your stomach is emptying.
The GEBT has been validated against gastric scintigraphy in clinical trials, showing 73-97% agreement with scintigraphy results across different measurement times. In 2021, the FDA expanded approval to allow GEBT to be administered at home via telehealth, making this test even more accessible.
Why Patients Appreciate GEBT
Many patients tell us they prefer GEBT because:
- No radiation exposure – you can avoid even the small amount of radioactive material used in scintigraphy
- Convenience – the test can be done in your doctor’s office or even at home, rather than requiring travel to a specialized hospital facility
- Accessibility – you don’t need to live near a nuclear medicine center or wait weeks for an appointment
- Non-invasive – you’re simply eating a meal and providing breath samples
- Safety – carbon-13 is completely safe and naturally occurs in your body
How to Get Started with Testing
If you’re ready to get answers about what’s been causing your symptoms, here’s what to do:
Schedule an appointment with your primary care physician or gastroenterologist. Come prepared to discuss your symptoms in detail—when they started, what makes them better or worse, and how they’re affecting your daily life and nutrition. Your doctor can evaluate whether gastroparesis testing would be appropriate for you.
If your healthcare provider determines that a gastric emptying test would help with your diagnosis, they can order either traditional scintigraphy or the GEBT. If they choose GEBT, Cairn Diagnostics will work with you to schedule the test at your earliest convenience—potentially soon enough to help you manage symptoms before this holiday season.
We know that dealing with unexplained digestive symptoms can be exhausting and isolating. But getting a clear diagnosis is the first step toward feeling better.

Practical Tips for Managing Gastroparesis During the Holidays
While getting properly diagnosed and starting treatment is essential for long-term management, you may be wondering what you can do right now to make the upcoming holidays more manageable. Here are some strategies that many people with gastroparesis find helpful:
Communicate with loved ones ahead of time. Let your host know about your dietary needs before the gathering. Most people want to help—they just need to know how. You might offer to bring a dish you know you can tolerate, so you’re guaranteed to have something safe to eat.
Adjust your meal approach. Instead of trying to eat a traditional large holiday meal, plan to eat smaller amounts more frequently throughout the day. It’s okay to eat at your own pace and to stop when you need to, even if others are still eating.
Choose foods wisely. Focus on low-fat, low-fiber foods that are easier to digest. Well-cooked vegetables, lean proteins, and softer textures tend to be better tolerated. You might want to avoid the rich, heavy dishes and stick with simpler options.
Stay upright after eating. Gravity can help with digestion, so try to remain sitting or standing for at least an hour or two after eating, rather than lying down.
Manage your expectations—and be kind to yourself. If you can’t participate in meals the way you used to, that’s okay. Focus on the aspects of gatherings you can enjoy—the conversation, the company, the traditions that don’t revolve around food. You don’t have to explain or apologize for taking care of your health.
Consider liquid nutrition. If solid foods are particularly difficult, nutritional supplement drinks might help you maintain adequate nutrition during challenging times.
Follow your treatment plan. If you’re already being treated for gastroparesis, take your medications as prescribed, especially before meals. If you’re experiencing worsening symptoms during the holidays, reach out to your healthcare provider—don’t wait until after the new year.
Remember, managing gastroparesis is an ongoing journey, and it’s okay to have difficult days. Be patient with yourself as you figure out what works best for your body.
Your Questions About Gastroparesis and Testing—Answered
We know you have questions about gastroparesis and testing options. Here are answers to the most common concerns we hear from patients:
What exactly is gastroparesis?
Gastroparesis is a disorder where your stomach takes much longer than normal to empty food into your small intestine. With gastroparesis, stomach muscle contractions are weakened or don’t work properly, so food sits in your stomach longer than it should.
The most common causes include diabetes (57% of cases), post-surgical complications (15%), medications like narcotic pain relievers (12%), and unknown causes (11%). It can also develop after viral infections, in people with Parkinson’s disease, or those with severe GERD.
What is the Gastric Emptying Breath Test (GEBT)?
GEBT is an FDA-approved test that measures how quickly your stomach empties without using radioactive materials. Approved in 2015, it showed 73-97% agreement with traditional scintigraphy. In 2021, the FDA expanded approval to allow at-home administration via telehealth.
How does GEBT work?
After an overnight fast, you provide baseline breath samples, then eat a standardized test meal containing egg mixture, Spirulina (a blue-green algae), and saltine crackers. The Spirulina is enriched with carbon-13, a naturally occurring, non-radioactive form of carbon that’s already in your body.
You’ll provide breath samples at 45, 90, 120, 150, 180, and 240 minutes. These samples are sent to a certified laboratory where they measure how quickly carbon-13 appears in your breath—which directly reflects how fast your stomach is emptying.
Who should consider GEBT, and who should avoid it?
Your doctor might recommend GEBT if you’re experiencing nausea after eating, vomiting, early fullness, bloating, or upper abdominal pain. However, you should not take this test if you have allergies to Spirulina, eggs, milk, or wheat, certain lung diseases, or conditions causing small bowel malabsorption. Discuss any allergies or medical conditions with your healthcare provider.
Is GEBT safe?
Yes, GEBT is very safe. Carbon-13 is naturally occurring and makes up 1.1% of all carbon in nature—it’s already in your body and food. The FDA approved GEBT in 2015 after reviewing extensive safety data. Reported side effects were mild (nausea, heartburn) and likely related to gastroparesis itself, not the test. No serious adverse events were reported.
Can I take this test at home?
Yes! GEBT can be administered at home under virtual supervision via telehealth (FDA-approved in 2021). Cairn Diagnostics ships the test kit to you with complete instructions. You’ll connect with healthcare professionals via telehealth for guidance, then mail your breath samples back to the laboratory. This is especially helpful if you live far from a nuclear medicine facility, have mobility issues, or prefer testing at home.
How long does the test take?
The GEBT takes four hours—the same as traditional scintigraphy. You’ll need to fast overnight (8-12 hours), then be available for the four-hour testing period. Between breath sample collections, you can read, watch TV, or work on a laptop. Many patients find it more comfortable than lying under a camera for scintigraphy.
Will my insurance cover GEBT?
Many insurance plans cover GEBT when ordered by your healthcare provider. Medicare approved coverage in July 2020. For private insurance, Cairn Diagnostics works with most major providers and can verify your coverage before testing. Visit the patient information page to learn about coverage and costs. If cost is a concern, don’t let it prevent you from asking—Cairn’s patient services team can help you understand your options.
