During the preconception stage, it is possible to test for Helicobacter pylori, but if testing is to be conducted, breath tests should be avoided. This is because breath tests use carbon-14 or carbon-13, which are radioactive, making them unsuitable for women planning pregnancy.

At this time, it is also important to weigh the pros and cons. If there are chronic gastric or duodenal ulcers, and the symptoms are quite apparent, it is necessary to conduct tests. It is advisable to postpone pregnancy, address the gastrointestinal diseases first, and then proceed with pregnancy. If there are gastric or duodenal diseases at such time, pregnancy could possibly exacerbate the condition.

How to treat duodenal ulcer with Helicobacter pylori infection?

The treatment of duodenal ulcer accompanied by Helicobacter pylori infection begins primarily with anti-Helicobacter pylori therapy. The regimen includes a proton pump inhibitor, two types of antibiotics, and a bismuth agent, lasting a total of 14 days. In addition, for duodenal ulcers, it is necessary to use acid-suppressing and stomach-protecting medications to promote gastric mobility and protect the gastric mucosa, with the treatment course lasting six weeks. At the same time, it is important to focus on a light and easily digestible diet, avoiding smoking and drinking alcohol, as well as avoiding strong tea, coffee, spicy, irritating, fried, grilled, raw, cold, and sweet foods. It is also crucial to avoid adverse emotional effects such as anxiety, depression, and stress, prevent excessive fatigue or staying up late, and it is advised to moderately increase physical activity.

Can a gastroscopy check for Helicobacter pylori?

Normally, when conducting a gastroscopy, it is possible to test for Helicobacter pylori, but this method of detection is less commonly used in clinical practice nowadays, as it requires undergoing a gastroscopy, which can be quite distressing and may cause nausea and vomiting. Currently, the main method used in clinical practice for detecting Helicobacter pylori is the breath test, typically using carbon-13 or carbon-14. This involves swallowing a capsule and then blowing into a device to test for Helicobacter pylori infection. This method is more convenient, which is why it has increasingly replaced gastroscopy for detecting Helicobacter pylori.

Is the treatment process for Helicobacter pylori uncomfortable?

The treatment process for Helicobacter pylori infection is not uncomfortable, primarily involving oral medication. Treatment options include a combination of two antibiotics such as amoxicillin, clarithromycin, furazolidone, metronidazole, etc., alongside a proton pump inhibitor like omeprazole, pantoprazole, or lansoprazole, and the addition of bismuth citrate. This forms a quadruple therapy administered over two weeks to eradicate the infection. During treatment for Helicobacter pylori infection, it is advised to consume a diet rich in vitamins, incorporating fresh vegetables and fruits. It is important to eat regularly, avoid overeating or consuming oily, spicy, and irritating foods. (Please follow medical advice when using medications.)

Do you have to take medication if you test positive for Helicobacter pylori?

Helicobacter pylori has been confirmed as a significant cause of chronic gastritis, peptic ulcers, and gastric cancer. The infection rate of Helicobacter pylori in China is very high, exceeding 50%, and is closely related to the dietary habits of the Chinese people, as they tend to share dishes, making it easy to transmit Helicobacter pylori. Is medication necessary if one is infected with Helicobacter pylori? The answer is not necessarily. Treatment for Helicobacter pylori is only needed if there is accompanying chronic gastritis, erosion, peptic ulcers, or a family history of certain gastrointestinal diseases. If there are no symptoms and no family history of such diseases, and only a positive Helicobacter pylori test, medication may not be necessary.

Does the breath test for Helicobacter pylori require fasting?

Currently, the detection of Helicobacter pylori is highly accurate and specific, and a rapid, simple, and effective method is the Carbon-14 breath test. The Carbon-14 breath test requires no eating within six hours, so it is best to take it on an empty stomach. Therefore, it is preferable to test for Helicobacter pylori on an empty stomach. Currently, the infection rate of Helicobacter pylori in our country has exceeded 50%. Helicobacter pylori is the principal cause of chronic gastritis, peptic ulcers, or gastric cancer. Therefore, if symptoms of the digestive system occur, such as belching, acid reflux, upper abdominal pain, nausea, and poor appetite, it is advisable to conduct a test for Helicobacter pylori, specifically the Carbon-14 breath test, to confirm the infection of Helicobacter pylori.
