What is Helicobacter Pylori ?
Helicobacter pylori is a Gram-negative bacillus that usually resides in the mucosa of the human stomach. This bacterium is one of the main causative factors of gastritis and gastric ulcer, and is also related to the occurrence of gastric cancer.
Gastric H. pylori infection is usually transmitted through the oral-oral or fecal-oral routes. The infection usually develops in childhood, but many people carry the bacteria throughout their lives without showing any symptoms. However, some infected people may develop diseases such as gastritis, stomach ulcers, and even stomach cancer.
The symptoms of Helicobacter Pylori infection
Infection with gastric Helicobacter pylori may cause the following symptoms:
1. Indigestion: including symptoms such as heartburn, stomach pain, bloating, nausea, and vomiting.
2. Gastrointestinal bleeding: may lead to melena or vomiting blood.
3. Weight loss: Long-term infection may lead to weight loss.
4. Loss of appetite: Loss of appetite or decreased appetite may occur.
5. Diarrhea: Some patients may experience diarrhea.
It is important to note that some infected people may not have any symptoms, while others may experience some of the above symptoms.
Dection Method
1. Urea breath test: This is a non-invasive detection method. The patient drinks a solution containing labeled urea, and then detects whether the exhaled breath contains labeled carbon dioxide to determine whether he is infected with Helicobacter pylori.
2.Serum antibody detection: Determine whether the patient is infected with Helicobacter pylori by detecting the antibody level in the patient’s serum. This method can determine whether a previous infection has occurred, but it cannot differentiate between an active infection and a past infection.
3.Stool antigen detection: Determine whether the patient is infected with Helicobacter pylori by detecting the antigen in the patient’s stool. This is a non-invasive test suitable for children and patients who cannot undergo gastroscopy.
4.Gastroscopy: Confirm the infection through gastroscopy and take tissue specimens for rapid urease test (RUT) or tissue culture of Helicobacter pylori.
