What is bacteria causing peptic ulcer
The bacteria that is primarily responsible for causing peptic ulcers is called Helicobacter pylori (H. pylori). This bacterium is able to survive and thrive in the acidic environment of the stomach, which allows it to colonize the stomach lining and cause inflammation and damage.
To determine that H. pylori is the bacterium causing the peptic ulcer, a diagnostic test is typically conducted. There are several methods for identifying H. pylori, including:
1. Breath Test: This is a common and non-invasive method where a patient consumes a substance, such as urea, that is metabolized by H. pylori. If H. pylori is present, it produces specific compounds that can be detected in the breath.
2. Stool Test: In this test, a small stool sample is analyzed for the presence of H. pylori antigens or DNA. This method is also non-invasive but may not be as accurate as other tests.
3. Blood Test: Blood tests measure the presence of antibodies produced by the immune system in response to H. pylori infection. However, blood tests cannot differentiate between past and current infections.
4. Endoscopy: This is an invasive procedure where a thin, flexible tube with a camera (endoscope) is inserted through the mouth into the stomach. During the procedure, a biopsy (tissue sample) may be taken, and then tested for H. pylori presence.
It's important to consult with a healthcare professional if you suspect you have a peptic ulcer or if you want to test for H. pylori infection. They can provide the most appropriate advice and guide you through the necessary diagnostic process.
