Using communal chopsticks and serving food separately during gatherings isn't just civilized—it also promotes health. But do you know what disease this practice most effectively prevents?Preventing Helicobacter pylori infection!
What is Helicobacter pylori? Commonly abbreviated as HP, this spiral-shaped bacterium colonizes the gastric mucosal epithelium. Substances it secretes, such as urease, can disrupt gastric acid secretion and damage the gastric mucosal barrier. It is a major cause of chronic gastritis, gastric or duodenal ulcers, and even gastric cancer.
Helicobacter pylori infection is common among the population but often overlooked. Most infected individuals experience no symptoms or discomfort, leading some to seek medical attention only after developing severe gastric conditions.
Helicobacter pylori is closely linked to gastric cancer.
As the saying goes, "Nine out of ten people have stomach issues." Gastric discomfort and various stomach ailments have become widespread among modern individuals.Epidemiological studies indicate that Helicobacter pylori (HP) infection rates remain high in certain countries and regions. In China, HP detection rates in the stomach range from approximately 30% to 70% across different regions and ethnic groups.
However, most infected individuals exhibit no obvious symptoms and may never develop the disease.Dr. Mai Yunping explains: Since the stomach lacks nerve endings, people often fail to notice gastric issues until the condition has progressed significantly. HP infection causes chronic gastritis, presenting symptoms such as bad breath, upper abdominal discomfort, dull pain, and occasionally belching or acid reflux. The disease progresses slowly with subtle sensations but tends to recur frequently.
Helicobacter pylori also carries a severe consequence—gastric cancer. World Health Organization reports indicate that approximately 50% of gastric cancers are associated with this bacterium. A study by Kyushu University in Japan revealed that gastric cancer development is not only closely linked to dietary habits but is also a transmissible disease.Gastritis and peptic ulcers triggered by H. pylori transform gastric cancer into an orally transmitted infectious disease. A 2008 report in the prestigious medical journal The Lancet further indicated that eradicating H. pylori after gastric cancer surgery reduces the likelihood of recurrence.
Beware of Diseases Entering Through the Mouth
HP exhibits strong infectivity, typically spreading via oral-oral or fecal-oral routes. Close contact, consuming contaminated food or water, and other means can all facilitate transmission. Overseas studies have detected HP in 4% of urban drinking water samples, and it has also been found on the surfaces of vegetables and other foods.
Experts note that Chinese dining culture often involves communal meals, where shared dishes can introduce various pathogens into every diner's stomach. This facilitates HP transmission, making family-wide infection highly likely—especially when mothers pre-chew food for infants.The use of communal chopsticks, individual utensils, and the promotion of separate serving practices help prevent bacterial infection. When dining out, prioritize food hygiene by choosing clean, well-maintained dining environments.
Additionally, close contact among family members, intimate conversations, improper handling of infant excrement, and interactions between children and students at school can all transmit Helicobacter pylori.
A Simple Breath Test for Detection
Methods for diagnosing Helicobacter pylori infection include blood tests, stool examinations, carbon-13 or -14 breath tests, and gastroscopy, with the carbon breath test being the most common.Patients simply take a carbon-labeled medication and exhale into a collection bag before and after ingestion. The instrument then detects the presence of H. pylori infection. This method is simple, safe, and rapid, with the entire diagnostic process taking approximately 30 minutes.
Experts also note that a negative endoscopy result does not rule out Helicobacter pylori infection, recommending testing for more objective results. Due to its high sensitivity and specificity, the breath test remains the preferred method for post-treatment follow-up in most patients.
It's important to note that a positive H. pylori test result shouldn't cause undue alarm, as not everyone requires treatment. However, individuals with chronic gastritis accompanied by mucosal atrophy or erosion, or those with a family history of gastric cancer, should be vigilant. H. pylori may increase their risk of developing gastric cancer, making eradication therapy essential.Dr. Mai Yunping emphasizes that Hp eradication should follow standardized quadruple therapy protocols. Failure to do so may reduce success rates due to antibiotic resistance.
Tips
Preventing H. pylori infection, like other gastrointestinal infections, hinges on controlling "disease transmission through the mouth." Prioritizing dietary hygiene is paramount.
1. Washing hands before meals and after using the restroom is a critical step directly affecting whether H. pylori enters the body.
2. Raw meat must be avoided. Many people enjoy medium-rare steak or eat meat before it's fully cooked in hot pot, which significantly increases exposure to H. pylori.
3. Helicobacter pylori can also grow and multiply in dental plaque and cavities. Thorough and careful brushing is the most effective method to remove plaque and prevent cavities.
4. When consuming vegetables or fruits, ensure they are disinfected, thoroughly washed, or peeled. Use communal chopsticks during meals.
5. For infants just learning to eat or young children who are difficult to feed, parents should avoid chewing food to feed them.
