Digestive health plays a key role in how you feel day to day, influencing everything from nutrient absorption to overall comfort. When imbalances occur, they can disrupt this delicate system and impact your well-being. Heliobacter Pylori has become an important focus in digestive health, as more people look for ways to better support their gut and maintain balance.
In this article, we'll explore how to support your digestive system and promote optimal gut health.
What is Heliobacter Pylori?
Helicobacter pylori (H. pylori) is a bacterium that is estimated to already infect over 50% of the world’s population. Most commonly (in over 80% of cases), there are no symptoms of infection. This bacterium is stable in the strongly acidic environment of the stomach because H. pylori is able to raise the pH in a mini-environment around itself.
At the same time, H. pylori reduces plasma levels of certain hormones that affect appetite and trigger the release of inflammatory molecules into the circulation. These effects combine to cause the digestive symptoms commonly associated with H. pylori, and can trigger other inflammatory processes in the body like arteriosclerosis.
Sources of Infection
Researchers have not yet identified how H. pylori spreads. Scientists suspect contaminated food or water may transmit it. Current research remains inconclusive. Some infected people carry H. pylori in their saliva. The bacteria may also spread through saliva contact or shared utensils.
Signs and Symptoms of Heliobacter Pylori Infection
Most people with H. pylori infection remain asymptomatic carriers. However, some individuals develop symptoms commonly associated with the infection. Some possible signs and symptoms are:
- Abdominal pain or discomfort
- Nausea
- Frequent burping
- Vomiting
- Fatigue
- Decreased appetite
- Bloating
- Weight loss
Illnesses Associated with H. pylori Infection
H. pylori infection has been linked to an increased risk of several diseases. Gastric cancer remains the most serious concern. This is likely due to the association of infection with initiating conditions such as gastritis and peptic ulcers. Both of these conditions increase cell turnover, and it is this increased replication of cells that causes a higher risk of DNA errors and thus cancer. In fact, the World Health Organization has classified H. pylori as a group A carcinogen (cancer-causing agent). Interestingly, recent research has also found a correlation between infection with certain H. pylori strains and an increased risk of a serious thyroid condition known as Graves’ disease. Other inflammatory conditions have also been associated with the immune response triggered by H. pylori infection. The most common of these is arteriosclerosis.
The Role of Stomach Acid
Stomach acid in the body is responsible for activating digestive enzymes in the stomach for proper digestion. It also protects the digestive tract against invading pathogens like bacteria and parasites. During infection with H. pylori, the levels of bacteria grow larger until the basic environment that they create can actually negate the stomach acid present and prevent proper digestion and defense.
Nutritional Deficiencies Associated With Heliobacter Pylori
There is an association between H. pylori infection and iron deficiency anemia, as well as reduced absorption of vitamin B12, vitamin A, C, E, and folic acid. These are all due to the hypochlorhydria (reduced stomach acid) or achlorhydria (absent stomach acid) caused by infection. This reduced stomach acid also allows for other bacterial infections to invade the digestive tract, which can lead to further complications such as diarrhea and leaky gut syndrome.
How Is H. Pylori Diagnosed?
There are various methods of testing available to find out if you are infected with H. pylori. There are tests that check your bodily fluids, like tests for stool samples that look for a bacterium called Hp antigens and blood tests that look for the presence of H. pylori antibodies. Endoscopy with biopsy is the most invasive diagnostic method. Doctors pass a small camera through the throat and collect tissue samples. They then check for inflammation and infection. An easier, less invasive test called a urea breath test is available as well. During this test, patients swallow a radio labeled urea solution or capsule. Clinicians test the breath 15 to 30 minutes later. If H. pylori is present, it breaks down urea into carbon dioxide and releases it through the breath. Without H. pylori, the body absorbs the urea completely and excretes it in urine. Thus, the presence of the radiolabel in the breath represents a positive H. pylori breath test.
What Are Treatment Options for Heliobacter Pylori?
Conventional Treatment
When doctors diagnose H. pylori infection, they often prescribe triple therapy. This treatment combines two antibiotics with a proton pump inhibitor (PPI). Common antibiotics include amoxicillin, clarithromycin, metronidazole, tetracycline, and levofloxacin. In recent years, antibiotic therapy success rates have been dropping, and current research indicates a success rate well below 80% because of the development of increasing antibiotic resistance.
Natural Supplements For Heliobacter Pylori
Probiotics – L. rhamnosus
Probiotics have been clinically shown to help reduce the inflammatory effects of H. pylori infection. Thus, supplementation with beneficial bacteria may help to reduce some of the side effects associated with infection. One particularly beneficial strain against H. pylori is Lactobacillus rhamnosus (L. rhamnosus). It is particularly able to withstand the acid environment of the stomach, which allows it to directly compete with H. pylori there. A good multi-strain probiotic, high in L. rhamnosus, will help to reduce the symptoms of a current H. Helicobacter pylori infection can also protect against reinfection after treatment.
Sulforaphane
Cruciferous vegetables such as broccoli, cabbage, brussel sprouts, cauliflower, and kale all contain a substance called sulforaphane (SGS). Research shows that SGS may help destroy H. pylori. SGS may also protect against gastric irritation linked to ulcers and stomach cancer. In addition to food sources, SGS is available as a supplement.
Mastic Gum
Studies show that two weeks of mastic gum supplementation can significantly reduce peptic ulcer symptoms. Longer use may help reduce H. pylori levels in the digetive tract. However, researchers continue to debate its effectiveness as a complete treatment for H. pylori infection.
Other Treatments – Stomach pH
Many proposed treatments for H. pylori are available. However, research does not support all of these treatment options. Some of these are manuka honey, apple cider vinegar, and some other antibacterial or acid-promoting supplements. Raising the acid content in the stomach can make it harder for H. pylori to survive, but unfortunately, it can also further damage the stomach lining. This is especially risky in those already suffering from gastritis or ulceration of the stomach. Altering your stomach pH in these cases should only be done under the supervision of your healthcare provider.
Protecting the Stomach
Because H. pylori bacteria damage the stomach lining, it is important to combine antibacterial treatments with supplements that can soothe and protect the digestive lining. Herbs that perform this function are called demulcents. Some great demulcents are: slippery elm, marshmallow, and licorice.




I have been looking for information on which probiotic strains are good for H. pylori, good to know that L. Rhamnosus is one of them. My current multi-strain probiotics have L. Rhamnosus in it but only at 2 Billion cfu(total 10B), not sure if this amount is effective. I might need to look for a product higher in this strain. Thanks for the article!
Hello, Rita,

Have a healthy day.
As a PhD student studying the human gut microbiome in health and disease, there is no way I wouldn't know that H. pylori is a class A carcinogen. But, I did not know the mechanism, so thank you for teaching me that how H. pylori causes unhealthy cell growth through increasing cell turnover and replication because of its infection causing gastritis and peptic ulcers. Also, I heard mastic gum had health benefits but did not know that it could be used in treating H. pylori infection-noted!
Hello Rachel,
We're happy you enjoyed this article and reading more about its effects on health. Antioxidants are great ways to protect your body against carcinogen's and substances that disrupt healthy cells, you can learn all about them here: https://www.nationalnutrition.ca/articles/supplements/antioxidants/
