Why Age Makes This Infection More Important
As we get older, digestive health can become increasingly important to overall wellbeing. One condition that deserves particular attention is infection with Helicobacter pylori (H. pylori), a bacterium that can live in the stomach for many years, sometimes without causing obvious symptoms.
For older adults, understanding H. pylori may be especially important because long-standing infection can be associated with several gastrointestinal conditions, including peptic ulcers, gastritis and an increased risk of gastric cancer.
Why H. pylori Matters More as We Age
H. pylori infection is often acquired earlier in life and can persist for decades if it is not detected and treated. Research into older adults has highlighted the importance of considering the infection alongside other factors that can affect gastrointestinal health later in life.
Older people are also more likely to use medications such as aspirin or non-steroidal anti-inflammatory drugs (NSAIDs). These medicines can increase the risk of gastrointestinal ulcers and bleeding, making the presence of H. pylori particularly relevant. A review of H. pylori in older people noted the interaction between infection, medication use, gastric changes and age-related health factors.

Long-Term Infection and Stomach Health
One of the reasons H. pylori deserves attention is that infection can persist for years. Chronic infection may contribute to ongoing inflammation of the stomach lining and, in some people, progression toward conditions such as atrophic gastritis and intestinal metaplasia.
Most importantly, H. pylori is recognised as an important cause of gastric cancer. The International Agency for Research on Cancer (IARC), part of the World Health Organization, has published guidance on population-based H. pylori “screen-and-treat” strategies specifically aimed at gastric cancer prevention.
This does not mean that everyone with H. pylori will develop cancer. Rather, it highlights why identifying and appropriately managing persistent infection can be an important part of long-term digestive health.
What About Cognitive Health?
An emerging area of research is the possible relationship between H. pylori and cognitive health.
A 2023 two-year follow-up study involving 268 older adults with memory complaints found that participants with a history of H. pylori infection experienced greater cognitive decline during the study period than those without infection. After adjustment for several factors, H. pylori infection was associated with an increased risk of longitudinal cognitive decline.
These findings are interesting, but they need to be interpreted carefully. The study demonstrates an association, not proof that H. pylori causes dementia or cognitive decline. Researchers are continuing to investigate possible explanations, including chronic inflammation, nutritional factors and interactions between the gastrointestinal system and the brain.
Testing and Treatment in Older Adults
If an older adult has persistent digestive symptoms, a history of ulcers, unexplained iron deficiency, gastrointestinal bleeding, or other risk factors, discussing H. pylori testing with a healthcare professional may be appropriate.
Testing may involve a urea breath test, stool antigen test or, in certain circumstances, endoscopy and biopsy. The most appropriate approach depends on the individual’s symptoms, medical history and medications.
If H. pylori is confirmed, current medical guidelines generally recommend evidence-based eradication therapy. A 2025 systematic review and meta-analysis specifically examining people aged 60 and older found that eradication can be effective, but treatment success varies considerably between regimens and antibiotic resistance is an important consideration.
This is particularly relevant for older adults, who may already be taking several medications and may have other health considerations that need to be taken into account.
Supporting Digestive Health Naturally
Alongside appropriate medical care, many people are interested in natural approaches to supporting digestive wellness. Herbal preparations such as Matula Tea™ are used as part of natural digestive-health routines.
However, natural support should not be presented as a replacement for appropriate medical diagnosis or proven H. pylori eradication therapy. Anyone with a confirmed infection should discuss treatment options with a qualified healthcare professional.
For older adults, the bigger picture is important: maintaining good digestive health involves paying attention to symptoms, appropriate testing, medication use, nutrition and regular medical care.
The Bottom Line
H. pylori can be easy to overlook, particularly when symptoms are mild or absent. Yet persistent infection can have important long-term implications for stomach health.
For older adults, understanding the infection, knowing when testing may be appropriate, and discussing evidence-based treatment options can be an important part of protecting digestive health as we age.
