A hydrogen breath test is a common screening to measure the amount of hydrogen present in a person’s breath. The amount of hydrogen in the breath can provide an indication of gastrointestinal disease or illness. In people, anaerobic bacteria located in the colon is the only type of bacteria that can produce hydrogen. When you see a Brooklyn gastrointestinal doctor at our office in Cobble Hill or on Ocean Parkway in Brooklyn, NY, he or she may recommend this test if there is a reason to believe you have an associated illness.
What Does a Hydrogen Breath Test Tell You?
Bacteria is present throughout the gastrointestinal tract, and that’s normal. However, the right amount and type of bacteria is important for overall gastro health. When bacteria present in this tract are exposed to unabsorbed food, especially carbs and sugars, they produce hydrogen. Small amounts of hydrogen are normal but a large amount of hydrogen found on a hydrogen breath test by a Brooklyn gastro doctor can be problematic. This indicates a digestion problem present, most likely in the small intestine. Also, when a large amount of hydrogen is present, colon bacteria may move into the small intestine. This can cause exposure to unabsorbed food, resulting in high hydrogen production.
When Will a Brooklyn Gastro Doctor Recommend a Hydrogen Breath Test?
When a doctor believes one of three conditions may be present:
- Dietary sugars are not digested normally. This is common in lactose intolerance, and may be from sucrose, fructose, or sorbitol.
- Bacterial overgrowth in the small bowel is present. This occurs when a large number of colonic bacteria are in the small intestine.
- Rapid passage of food through the small intestine is occurring.
- Individuals who have symptoms such as abdominal bloating and pain, diarrhea, flatulence, and distention may require this type of testing.
How Is a Hydrogen Breath Test Performed?
You’ll fast for at least 12 hours prior to the test. You’ll blow into a balloon to fill it with air. Then, the doctor can measure the amount of hydrogen present in that air as it is released. At this step, you will then ingest a small amount of test sugar, usually the type of sugar product (such as lactose, fructose, or sorbitol thought to be the problem). You’ll provide additional breath samples over a period of 15 minutes for several hours.
After the testing, your Brooklyn gastroenterologist will try to determine if there is any type of intolerance present and offer recommendations for treatment and care. The hydrogen breath test is very effective for measuring dietary sugar intolerance and rapid passing of food through the intestine. It generally is only 60% successful in detecting overgrowth of bacteria. This may require further testing.
Getting the Care You Need
If you have pain or discomfort after eating in your abdomen, it is a good idea to consult with our Brooklyn gastro doctor to determine if a hydrogen breath test is necessary. This, along with other diagnostic information, can provide a snapshot of what’s happening within your digestive system and may lead to treatment and improvement in quality of life.
Frequently Asked Questions About Hydrogen Breath Test
How can you tell if I have a problem just from testing my breath?
It’s simple! A hydrogen breath test (HBT) measures the amount of hydrogen or methane gas in your breath. These gases are produced when bacteria in your gut break down sugars. If certain sugars are not properly absorbed or if there’s bacterial overgrowth (explained below), gas levels rise. These gases are absorbed into the blood and pumped into the lungs, where you breathe them out. A simple hydrogen breath test helps your doctor identify digestive issues such as bloating, IBS, abdominal distention, and lactose intolerance.
Is it accurate?
Yes! Breath testing has been around for over 40 years, and the medical literature has favorable results regarding its accuracy. When done correctly and with proper preparation, it provides valuable insights about your digestive system. Your gastro doctor will interpret the results along with your symptoms and medical history.
How long will this test take?
The test usually takes about 3-4 hours. The goal is to test gases during the entire digestion process. You will breathe into a collection device at set intervals after drinking a test solution. Given the time taken, we advise you to bring a book, an iPad, or something to help you pass the time.
How should I prepare for a hydrogen breath test?
Preparation is essential for accurate results. Prep involves fasting for a specific period (usually 12 hours) before the test. Certain foods, procedures, medications, and supplements may need to be avoided before the test. Our team will provide clear instructions before your appointment.
What happens if I fail to fast properly?
At the start of the test, we’ll ask you to provide a baseline breath to determine if you fasted as expected. You won’t pass the baseline readings if you don’t follow the recommended diet and fasting guidelines. This could mean delay or rescheduling the test. That’s why it’s essential to follow the preparation instructions to ensure reliable results and avoid unnecessary repeat testing.
What is Small Intestine Bacterial Overgrowth (SIBO)?
By nature, the small intestine contains far fewer bacteria than the large intestine. This is because food moves rapidly through it, and stomach acid prevents bacteria from growing. SIBO occurs when bacterial overgrowth occurs in the small intestine. Often, this indicates the presence of several conditions, including parasitic infection, low stomach acid, diabetes, Crohn’s disease, and slow food transit. SIBO can lead to symptoms like bloating, gas, diarrhea, constipation, and abdominal discomfort. We can detect SIBO with a hydrogen breath test.
Are there any risks or side effects associated with the hydrogen breath test?
Side effects are mild because the test is non-invasive. Some patients may experience mild bloating or gas after drinking the test solution. That’s it!
How much is a hydrogen breath test in Brooklyn, NY?
The cost of a hydrogen breath test is about $250, although it may be lower with insurance coverage. We’ll provide a cost breakdown and will answer any cost-related questions during your consultation. Rest assured, we won’t move forward until you are clear on costs.
