The most commonly used test for detecting Helicobacter pylori at present is the breath test, which generally comes in two types: carbon-13 and carbon-14, though the testing method is basically fixed. A barium meal test can only detect whether there are large gastric ulcers or the presence of gastric cancer, but Helicobacter pylori is quite small and cannot be detected through a barium meal. Therefore, the detection of Helicobacter pylori typically relies on traditional methods, such as breath tests or tests performed during gastroscopy.

Can a gastroscopy examine Helicobacter pylori?

Can a gastroscopy detect Helicobacter pylori? Helicobacter pylori is a type of bacteria, thus it cannot be seen with the naked eye. However, recent research shows that Helicobacter pylori is closely related to certain mucosal appearances observed under endoscopy. Therefore, endoscopists can infer the infection of Helicobacter pylori based on certain mucosal appearances. However, if a patient is just testing for Helicobacter pylori infection, there is no need for a gastroscopy. We can choose some non-invasive methods such as the carbon-13 breath test, carbon-14 breath test, stool antigen test, and serological antibody test, which are commonly used detection methods. Moreover, after treatment for Helicobacter pylori, it is recommended to choose the carbon-13 or carbon-14 breath test, as they are quite accurate.

Can I drink coffee during the treatment for Helicobacter pylori?

It is not recommended to drink coffee during the treatment for Helicobacter pylori. During the treatment for Helicobacter pylori infection, it is advised to consume more fresh vegetables and fruits rich in vitamins, maintain regular meals, and eat light, easily digestible foods. Avoid strong alcohol, strong tea, coffee, and also greasy foods. The main methods for detecting Helicobacter pylori infection are the carbon-13 urea breath test or the carbon-14 urea breath test. If the test results are positive, a standard eradication treatment using a bismuth-containing quadruple therapy for two weeks should be implemented. Additionally, a re-examination is needed one month after discontinuing the medication to confirm whether the eradication is complete.

Helicobacter pylori treatment for half a month, re-examination still positive, what could be the reason?

If a follow-up test for Helicobacter pylori is positive after half a month of treatment, it indicates that the treatment was not successful, and Helicobacter pylori is still present. At this point, it is necessary to adjust the medication plan and treat Helicobacter pylori again. The specific medication methods and treatment duration should be used under the guidance of a doctor. Treatment of Helicobacter pylori infection requires the use of a bismuth-containing quadruple therapy for two weeks to eradicate it. Additionally, the diet should include an increased intake of fresh vegetables and fruits rich in vitamins and avoid spicy and irritating foods. Smoking and alcohol should be avoided. (Please follow the doctor’s prescription for medication use.)

How many times a year should Helicobacter pylori be tested?

If Helicobacter pylori tests positive, then it is necessary to undergo standardized eradication treatment. A re-examination is needed one month after cessation of the eradication treatment to confirm whether the eradication was successful or the treatment failed. If the patient tests negative for Helicobacter pylori, then there is no need for repeated testing. Therefore, the frequency of testing for Helicobacter pylori within a year needs to be analyzed based on specific circumstances, using different testing methods and frequencies according to different situations. Patients infected with Helicobacter pylori should eat light, easily digestible foods, avoid overeating, and avoid spicy and irritating foods.
