1. What is Helicobacter pylori?
Helicobacter pylori or Helicobacter pylori, English name Helicobacterpylori, referred to as Hp. It is a gram-negative, microaerobic bacterium that lives in various areas of the stomach and duodenum. It can cause mild chronic inflammation of the gastric mucosa and may even lead to stomach and duodenal ulcers and stomach cancer. Discovered by Barry J. Marshall and J. Robin Warren, it is a unipolar, multi-flagellar, bluntly rounded terminal, spiral-curved bacterium. Length 2.5 to 4.0 μm, width 0.5 to 1.0 μm. Helicobacter pylori is a microaerobic bacteria, the environmental oxygen requirements are 5 to 8%, and cannot grow in the atmosphere or absolute anaerobic environment.
Helicobacter pylori disease is a spiral-shaped, microaerobic, growth-intensive bacterium. In 1983, it was first isolated from gastric mucosal biopsy tissue in patients with chronic active gastritis and is the only microbial species known to survive in the human stomach.
2. Infection symptoms
1. Helicobacter pylori can cause gastritis. The main clinical manifestations are: epigastric discomfort, dull pain, sometimes hiccups, acid reflux, nausea, vomiting and other symptoms, the course of the disease is slow, but easy to recur.
2. The main symptoms of Helicobacter pylori infection are acid reflux, heartburn, stomach pain and bad breath. This is mainly due to the crazy secretion of gastrin caused by Helicobacter pylori, which leads to acidic heartburn, and for patients with stomach and duodenal ulcers, Helicobacter pylori can cause the main symptoms of stomach pain, and one of the most direct causes of bad breath is Helicobacter pylori.
3, Helicobacter pylori infection is generally sometimes no particularly obvious symptoms, then generally through the examination to judge whether there is Helicobacter pylori infection, Helicobacter pylori this pathogenic bacteria, it is easy to induce the occurrence of gastrointestinal diseases. These are the manifestations of Helicobacter pylori symptoms.
4. After the patient is infected with Helicobacter pylori, a variety of pathogenic factors are produced, which causes gastric mucosal damage, the occurrence of clinical diseases is diverse, and the patients will mostly have acid reflux, belching, fullness, etc., which are more than the patients infected with Helicobacter pylori than the patients who are not infected with Helicobacter pylori.
Third, prevention and control methods
1. It is not difficult to completely eradicate Helicobacter pylori, 90% of bacterial infections can often be destroyed by Helicobacter pylori after 1 to 2 weeks of treatment.
2. Helicobacter pylori suggests that at least those who have had stomach surgery, have stomach problems or have relatives who have suffered from stomach cancer should be examined, and those who have been infected should receive sterilization treatment, which may control stomach cancer.
