What's the matter with Helicobacter pylori negative

Helicobacter pylori is a microaerophilic bacterium that is distributed in the stomach and duodenum of our body. This pathogen can cause mild chronic inflammation in our gastric mucosa, which can sometimes lead to gastric or duodenal ulcers. This pathogen has a great relationship with gastric cancer. Nearly more than 80% of germ carriers do not show specific symptoms. A negative Helicobacter pylori test result has its specific meaning, please see the detailed introduction below.

Negative results indicate no Helicobacter pylori infection. But it also depends on what kind of test is done. Some tests may have false negatives. I personally recommend the carbon 13 breath test, which has a sensitivity, specificity and accuracy of over 95%.

Helicobacter pylori infection is the main pathogenic factor of chronic active gastritis, peptic ulcer, gastric mucosa-associated lymphoid tissue (MALT) lymphoma and gastric cancer. Helicobacter pylori is highly contagious and can be transmitted through hands, unclean food, unclean utensils, feces, etc. Therefore, you should develop good hygiene habits in your daily diet to prevent infection. Pay attention to regular and quantitative meals, nutritious food, soft and easy to digest food, small meals, and chew slowly; avoid overeating, avoid raw, cold, spicy, fried and irritating foods, and avoid smoked and pickled foods. Pickled foods containing nitrosamines are also carcinogenic, and when combined with the positive effect of Helicobacter pylori, they will increase the chance of cancer.

Helicobacter pylori is a Gram-negative, microaerophilic bacterium that lives in various areas of the stomach and duodenum. It can cause mild chronic inflammation of the gastric mucosa, or even lead to gastric and duodenal ulcers and gastric cancer.

Helicobacter pylori is a bacteria of the genus Helicobacter. About 50% of the world's population is infected with this bacteria, and many of the infected people do not show symptoms. Especially in some developing countries, the infection rate is even higher. The specific route of Helicobacter pylori infection is not very clear at present. A vaccine against this pathogen is currently under development.
