H. pylori Natural Treatment: A Functional Dietitian’s Guide 

What is H. pylori? 

Helicobacter pylori (H. pylori) is a gram-negative, spiral-shaped bacterium that lives in the stomach. It colonizes the gastric mucosa, the protective lining of the stomach wall, and is among the most common chronic bacterial infections worldwide.

First discovered in 1983 by doctors Barry Marshall and Robin Warren, H. pylori changed how we understand digestive health. Before their Nobel Prize-winning work, stomach ulcers were blamed on stress and diet.

How Common is H. Pylori? 

The global prevalence is around 43.1%, representing billions of people. 

Rates are higher in areas with poor sanitation and lower socioeconomic conditions. In children and adolescents, prevalence remains as high as 35.1%.

Why Does it Matter? 

Many people with H. pylori have no symptoms. Around 80% of carriers are asymptomatic, yet all infected individuals develop some degree of gastritis. 

Without treatment, helicobacter pylori infections can lead to peptic ulcers, gastric cancer, and other serious conditions. The World Health Organization classifies H. Plylori as a Group 1 (definite) carcinogen.

None of this sounds good, does it? 

The good news is that H. pylori is well understood, testable, and treatable. Identifying it early gives you a real opportunity to protect your long-term gut health. If you have been experiencing unexplained digestive symptoms, getting tested is a simple and empowering first step.

How H. pylori Affects Your Gut Health 

H. pylori doesn’t just sit passively in the stomach. It actively damages the gastric mucosa and triggers a cascade of effects that can impact your entire digestive system. Here’s what the research shows.

Damage to the Stomach Lining

H. pylori colonizes the gastric mucosa and damages gastric epithelial cells through a range of virulence factors. Over time, this damage breaks down the stomach’s protective barrier and drives chronic inflammation.

Downstream Effects

• Chronic gastritis: H. pylori infection triggers persistent inflammation of the stomach lining. All infected individuals develop some degree of gastritis, even without noticeable symptoms.
• Peptic ulcers: Damage to the gastric mucosa leaves the stomach wall vulnerable to acid erosion. H. pylori is responsible for the majority of peptic ulcer cases worldwide.
• Increased gastric cancer risk: Chronic inflammation can progress through a series of changes in the stomach lining over time. Current research suggests that those with H. Pylori infections are six times more likely to develop stomach cancer than those who do not have H. Pylori. 
• Nutrient depletion: H. pylori disrupts stomach acid production, which impairs the absorption of key nutrients. Iron, vitamin B12, and zinc deficiencies are commonly associated with Helicobacter pylori infections.
• Gut microbiome disruption: H. pylori alters the gut environment. This disruption can negatively affect the balance of beneficial bacteria throughout the digestive tract.
• Leaky gut and immune activation: Damage to gastric epithelial cells can compromise gut barrier integrity. This may contribute to systemic inflammation and immune dysregulation over time.

Signs and Symptoms of an H. pylori Infection 

One of the most challenging things about H. pylori is that it often causes no obvious symptoms. Patients harboring the bacteria are typically asymptomatic, with symptoms developing only after gastritis and peptic ulcer disease have set in. Many people carry the infection for years without knowing it.

Common Symptoms

Dyspepsia is the predominant symptom. A person may present with epigastric pain, early satiety, nausea, vomiting, and heartburn. 

Other commonly reported symptoms include:

• Burning or gnawing stomach pain: This is often felt in the upper abdomen. It’s frequently worse on an empty stomach and can ease temporarily after eating.
• Bloating and excess gas: Disruption to the gastric mucosa impairs normal digestion. This can lead to uncomfortable bloating and increased gas after meals.
• Loss of appetite: Chronic inflammation of the stomach lining can suppress appetite. This may contribute to unintentional weight loss over time.
• Frequent burping: Impaired digestion and changes in stomach acid can contribute to excessive belching.

Beyond the Gut

H. pylori doesn’t always stay local. Multiple extragastric complications have been linked to H. pylori infection, including iron deficiency anemia, vitamin B12 deficiency, diabetes mellitus, cardiovascular diseases, and certain neurological disorders. Iron deficiency is particularly worth noting as it can appear even without obvious digestive symptoms, making H. pylori easy to overlook as an underlying cause of persistent digestive distress.

What Causes H. pylori?

H. pylori isn’t caused by stress or spicy food. It’s a bacterial infection transmitted from person to person. The infection is typically acquired in childhood and can persist throughout life without treatment. 

Although the exact mode of transmission isn’t fully understood, H. pylori is usually spread through:

• Fecal-oral transmission – fecal transmission to the mouth due to contaminated food, water, or poor handwashing practices
• The gastric-oral route mode of transmission occurs when someone has reflux or vomiting, as bacteria can spread from the stomach to the mouth.
• The oral-oral route is the direct transmission from an infected person’s mouth to an unlucky susceptible person. This can include close contact with an infected person and even sharing utensils, and may also spread through contaminated food and water. 

There are some things that can make some people more likely to acquire H. Pylori than others. Key risk factors for H. Pylori include:

• Crowded households or living conditions
• Having a parent or sibling with H. pylori
• Low socioeconomic status
• A family history of gastric disease 
• Anyone who regularly uses NSAIDs is also at higher risk.

Not everyone with H. pylori develops complications. Outcomes depend on bacterial strain virulence, immune response, diet, and genetic predisposition. This is why a functional approach looks beyond the infection itself and considers the full picture of a person’s health. A good functional practitioner should be able to rule H. Pylori in or out and if you do have it, they should help you get rid of it, resolve your symptoms, and help you understand why and how you acquired H. Pylori so you can keep it away. 

Functional Testing for H. pylori 

Testing for H. pylori is recommended for anyone with:

• A history of peptic ulcer disease
• A history of gastritis
• Unexplained or persistent digestive symptoms that haven’t responded to conventional treatment. 

The sooner H. Pylori is identified, the easier it is to address. Several diagnostic tests are available depending on your situation and what your healthcare provider recommends.

Urea breath test (UBT)

This is one of the most accurate and non-invasive methods for diagnosing H. pylori.You swallow a urea-containing substance and breathe into a bag, which detects whether H. pylori is present. 

Be sure to follow the pre-test prep instructions so your results are accurate. It’s recommended to stop proton pump inhibitors at least 2 weeks before testing and antibiotics at least 4 weeks before to avoid false-negative results.

Stool testing

Several options are available. As a patient, it’s important to understand how each works and who they are for. Always follow the specific prep instructions provided with your test to ensure accurate results.

For a more complete picture of digestive health, we recommend a comprehensive stool analysis, which assesses several markers of digestive health, including gut microbiome balance, digestive function, and inflammation markers, as well as H. pylori detection. 

Endoscopy with biopsy

This is more invasive and allows direct visualization of the stomach lining. Recommended for those over 55, those with alarm symptoms, or when other conditions need to be ruled out. Biopsy samples can be tested via rapid urease testing, histology, and culture. At our practice, we offer comprehensive functional testing for H. pylori and a personalized protocol based on your results. 

Getting the right test is the first step toward understanding what’s actually going on in your gut and building a treatment plan that works. If you’re ready to get answers, schedule an appointment today.

H. pylori Natural Treatment Options 

Conventional H. pylori Treatment

Before discussing natural treatment options, it’s important to understand the typical conventional medicine approach. Standard H. pylori treatment combines antibiotics with acid-suppressing medication. 

The most common approach is triple therapy, which includes a proton pump inhibitor alongside two antibiotics taken for 14 days. However, declining eradication rates and rising antibiotic resistance have made bismuth quadruple therapy the preferred first-line option in many current guidelines. 

It’s also important to note that antibiotics can significantly disrupt the gut microbiome. Research shows they can reduce beneficial gut bacteria by up to 30%, with microbial diversity often not fully recovering after treatment. 

H. pylori Natural Treatment

While natural therapies can significantly support eradication and improve outcomes, they are often most effective when used alongside or strategically instead of conventional treatment, depending on the case. 

Given rising antibiotic resistance and the impact antibiotics can have on the gut microbiome, a functional approach offers a compelling alternative. Using natural tools strategically can improve eradication rates, reduce adverse effects, and support gut healing throughout the process.

Our clinic uses the 5R protocol to solve digestive problems. We’ll review each supplement through this lens, with supporting research, and use this framework to build a customized protocol tailored to your specific needs.

Remove

The removal part of the 5R protocol is just that, the removal of stressors or triggers negatively impacting the gut. In this case we would target H. Pylori.

• Mastic gum: A resin with centuries of traditional use for digestive conditions. Clinical evidence shows mastic gum may reduce H. pylori colonization through its antimicrobial triterpenic acids. It’s one of the few natural products with both lab and human trial evidence specifically against H. pylori.
• Berberine: A plant-derived compound with broad-spectrum antimicrobial properties. Studies show berberine has direct antibacterial activity against H. pylori and is increasingly included in functional eradication protocols.
• Oregano oil: Contains carvacrol and thymol, bioactive compounds with documented antibacterial activity against H. pylori. It’s one of the most widely used herbal antimicrobials in natural H. pylori treatment protocols.
• Black cumin seed (Nigella sativa): Has demonstrated antimicrobial activity against H. pylori in clinical studies and is commonly included alongside other herbal antimicrobials in functional protocols.
• Targeted H. pylori supplement blends: Several professional-grade supplement companies formulate products specifically designed to target H. pylori, combining multiple antimicrobial and gut-healing ingredients in a single protocol. These blends can simplify the supplementation process and are worth discussing with a functional practitioner to find the right fit for your specific case.
• NAC (N-acetyl cysteine): Works differently from other natural treatments by targeting the protective biofilm H. pylori forms around itself. Breaking down this biofilm makes the bacteria more vulnerable to both natural and conventional treatments.
• Lactoferrin: A protein found in colostrum with direct antibacterial activity against H. pylori, including resistant strains. It’s increasingly included in functional protocols alongside eradication therapy due to its synergistic effects.

Replace

Again, it’s just as it sounds, we replace what is needed for optimal digestion and might include enzymes, HCl or bile salts to name a few.

• This will be different for everyone, and this is where you should be asking questions about why and how you contracted H. Pylori. As mentioned previously in this article.
• Also, be sure to see our food as medicine tips below for further enhancing H. pylori treatment through food choices.

Reinoculate

In this step, we add things back to the gut that it needs to maintain an optimal environment. Probiotics, prebiotics, and targeted nutrients are the mainstays of this phase.

• Probiotics are perhaps the most evidence-backed natural option for H. pylori. Multiple peer-reviewed meta-analyses confirm that probiotic supplementation improves eradication rates and reduces side effects, including diarrhea, nausea, and abdominal pain. Lactobacillus rhamnosus GG, Lactobacillus reuteri DSM 17938, Lactobacillus reuteri ATCC PTA 6475, Bifidobacterium lactis B94, and Saccharomyces cerevisiae var. boulardii (Biocodex strain) have the most clinical support. 
• Nutrient deficiencies are another important piece of the puzzle, which is often left out of conventional medicine protocols

H. pylori commonly depletes iron, ferritin, vitamin B12, zinc, and vitamin D. Testing nutrient levels helps identify deficiencies that need to be corrected alongside treatment. Correcting deficiencies will help the body heal and repair faster, and strengthen the immune system, which may decrease the risk of recurrence.

Repair

The repairing phase is all about healing the lining of the digestive tract.

• Zinc carnosine: Supports gastric mucosal integrity and helps protect the stomach lining during and after treatment. Commonly used in functional protocols to support healing and reduce the adverse effects of eradication therapy.
• Gut lining support: Compounds like DGL, slippery elm, marshmallow root, and aloe vera help soothe and repair the gastric mucosa during and after H. pylori treatment. These are often overlooked but play an important role in long-term recovery.

Rebalance

This is where we focus on long-term habits to maintain great gut health! 

It’s the lifestyle piece, think sleep, stress management, and long-term supplement support if needed. Rebalancing also includes being intentional about long-term diet strategies to maintain gut health. 

Because the most effective H. pylori natural treatment protocol will depend on your specific test results, symptoms, and overall gut health, there’s no one-size-fits-all approach. 

This is exactly why working with an integrative and functional dietitian matters. We can interpret your stool test results, identify co-infections or contributing factors, and build a targeted protocol that goes far beyond a generic supplement list.

Foods to fight H. pylori 

Incorporating the right foods to fight H. pylori can help reduce bacterial load, support the gastric mucosa, and create a less hospitable environment for the bacteria to thrive.

Here are our food as medicine recommendations for foods to intentionally consume while undergoing treatment for H. Pylori:

• Broccoli sprouts: Rich in sulforaphane, broccoli sprouts have the strongest food-based evidence against H. pylori and can help reduce colonization and gastric inflammation.
• Garlic: Contains allicin, a compound with well-documented antimicrobial properties that has shown inhibitory activity against H. pylori in multiple studies.
• Green tea: Rich in catechins, including EGCG, green tea has demonstrated antibacterial activity against H. pylori and may help reduce colonization in the gastric mucosa.
• Cranberry: Contains proanthocyanidins that inhibit H. pylori from adhering to the stomach lining, reducing its ability to colonize.
• Manuka honey: Has demonstrated antibacterial properties against H. pylori in lab studies and offers additional anti-inflammatory benefits for the stomach lining.
• Ginger: Contains gingerol and other bioactive compounds with anti-inflammatory and antimicrobial properties that may help reduce H. pylori activity.
• Fermented foods: Yogurt, kefir, and sauerkraut provide beneficial probiotic bacteria that can help inhibit H. pylori growth and support microbiome balance. While these foods offer antimicrobial benefits, they may not be well tolerated by everyone, particularly those with active gastritis or histamine sensitivity. 
• Oily fish: Salmon, sardines, and mackerel are rich in omega-3 fatty acids, which help reduce gastric inflammation associated with H. pylori infection.

Including these foods to fight H. pylori as part of a broader treatment protocol, alongside appropriate supplementation and medical guidance, gives you the best chance of eradication and recovery.

Replenishing Nutrient Deficiencies Caused by H. pylori

As mentioned, H. pylori disrupts stomach acid production and damages the gastric mucosa, both of which impair nutrient absorption. Testing and correcting these deficiencies should happen alongside treatment.

• Iron and ferritin: H. pylori impairs iron absorption and can cause iron deficiency anemia, even in people with no obvious digestive symptoms.
• Vitamin B12: Loss of stomach acid reduces the body’s ability to absorb B12, which can lead to fatigue, brain fog, and neurological symptoms over time.
• Zinc: Zinc is essential for stomach acid production and gut lining integrity, both of which are compromised by H. pylori infection.
• Vitamin D: Deficiency is commonly found in people with H. pylori and may reduce the effectiveness of both conventional and natural treatment approaches.
• Vitamin C: H. pylori reduces vitamin C levels in the gastric mucosa, and correcting this deficiency may support immune function and treatment outcomes.

When to Work With a Functional Dietitian 

H. pylori is more than “just” a bacterial infection and should be treated as such. It affects nutrient absorption, gut microbiome balance, immune function, and long-term digestive health. 

As functional dietitians, we take a root-cause approach that goes beyond simply eradicating the bacteria. 

A functional dietitian is right for you if you have:

• Tested positive for H. pylori and want a natural or integrative treatment approach
• “Normal” lab work, but you continue to experience unexplained gut issues
• Completed antibiotic treatment, but still have lingering digestive symptoms
• A history of recurring H. pylori infections
• Become tired of dealing with nutrient deficiencies like low iron or B12 that haven’t resolved
• A desire to take a deeper look at potential gut issues with comprehensive stool testing that looks beyond standard H. pylori detection

A functional dietitian can order the appropriate tests, identify imbalances in the context of your overall health, and build a personalized protocol to support eradication, gut healing, and long-term prevention. If any of the above resonates with you, getting the right support could make all the difference. 

If you’ve tried solving digestive issues, but still don’t feel like yourself, H. pylori could be the missing piece.

We help identify the root cause of your health issues with personalized testing and targeted protocols to rebalance the digestive system.

When to Seek Immediate Treatment

While H. pylori is typically a chronic, slow-moving infection, certain symptoms require prompt medical attention. Seek immediate care if you experience any of the following:

• Severe or sudden abdominal pain, particularly in the upper abdomen
• Vomiting blood or material that looks like coffee grounds
• Black, tarry, or bloody stools, which can indicate gastrointestinal bleeding
• Unexplained, rapid weight loss
• Difficulty swallowing or pain when swallowing
• Persistent vomiting that prevents you from keeping food or liquids down
• Signs of anemia, such as extreme fatigue, shortness of breath, or pale skin

These symptoms can signal a peptic ulcer, internal bleeding, or other serious complications that need to be evaluated by a medical doctor right away. Do not attempt to manage these symptoms with natural treatments alone.

If you are unsure whether your symptoms are urgent, err on the side of caution and contact your healthcare provider.

H. pylori Natural Treatment FAQs 

Can H. pylori Cause IBS? 

H. pylori can cause symptoms that overlap significantly with IBS, including bloating, abdominal pain, and altered bowel habits. Research suggests that H. pylori infection may contribute to IBS development in some people, which is why testing for H. pylori is worth considering if you have been struggling with IBS.

Can H. pylori be treated naturally? 

Natural treatments, including probiotics, mastic gum, broccoli sprouts, and herbal antimicrobials, have evidence supporting their ability to reduce H. pylori colonization. While natural approaches are unlikely to fully eradicate the infection on their own in severe cases, they can be highly effective as part of a comprehensive functional protocol.

What is H. pylori natural treatment? 

H. pylori natural treatment refers to the use of evidence-based supplements, botanicals, dietary changes, and gut healing strategies to reduce or eradicate H. pylori. A functional dietitian can help build a comprehensive, personalized protocol to rebalance and restore the gut, and also address nutrient deficiencies, which are common after H. pylori infection. 

How do I cure chronic gastritis after having H. pylori? 

Successful H. pylori eradication is the first step, but healing the gastric mucosa afterward is equally important. Gut lining support using compounds like zinc carnosine, DGL, slippery elm, and aloe vera, alongside dietary changes and microbiome restoration, can support long-term recovery from chronic gastritis.

Does taking raw garlic help for patients who have helicobacter pylori? 

Garlic contains allicin, a compound with demonstrated antimicrobial activity against H. pylori in lab studies. While raw garlic alone isn’t a reliable standalone treatment, it can be a useful dietary addition as part of a broader H. pylori natural treatment protocol.

Is yogurt helpful with the h pylori test resulted positive? 

Yogurt containing live probiotic cultures can be a helpful addition when you’ve tested positive for H. pylori. Probiotic-rich foods like yogurt support a healthy gut microbiome and may help reduce H. pylori load, though a high-quality probiotic supplement will typically provide more targeted strains and higher doses than food sources alone.
