Helicobacter pylori, once settled in the stomach and duodenum, can cause chronic inflammation of the gastric mucosa, leading to reduced stomach digestive function. Over time, this may lead to chronic gastritis, gastric ulcers, and even cause gastric cancer. So, what are the symptoms of Helicobacter pylori infection? In cases of mild infection, where the bacteria count is low, there might be no obvious symptoms, with only bad breath occurring. If a high bacteria count causes an inflammatory reaction in the gastric mucosa, symptoms can include stomach bloating, stomach pain, acid reflux, a feeling of fullness in the stomach, along with nausea and bad breath.

Can a gastroscopy detect Helicobacter pylori?

First, it is important to clarify that a gastroscopy and a Helicobacter pylori test are two completely different methods. Generally speaking, a gastroscopy cannot detect whether there is a Helicobacter pylori infection. A gastroscopy specifically involves passing through the pharynx, esophagus, stomach, and finally reaching the descending part of the duodenum. It allows clear observation of whether there is inflammation, ulcers, or neoplastic diseases in the upper gastrointestinal tract, and it is the clearest and most direct method for examining the upper gastrointestinal tract. Helicobacter pylori testing, on the other hand, can generally be conducted in several ways. Firstly, blood can be drawn to test for Helicobacter pylori antibodies. Secondly, a breath test can be done, which is currently the most commonly used method, such as the carbon-13 or carbon-14 breath tests. Other methods include taking a biopsy during gastroscopy for a rapid urease test, and culturing bacteria from a biopsy. Therefore, gastroscopy cannot be used to test for Helicobacter pylori.

Does everyone have Helicobacter pylori?

Helicobacter pylori is not present in everyone; the infection rate among the general population can reach about 60%. However, some people who are infected with Helicobacter pylori do not necessarily experience symptoms such as acid reflux, bloating, stomach pain, or bad breath. Some people develop symptoms after being infected with Helicobacter pylori, and subsequently, when they visit a hospital for examination, the infection with this bacterium can be detected. Additionally, there are individuals who exhibit such symptoms but are not infected with Helicobacter pylori. In summary, not everyone is infected with Helicobacter pylori, and not everyone who is infected shows symptoms.

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 you eat sweets during the treatment for Helicobacter pylori?

During the treatment of Helicobacter pylori, it is permissible to eat sweets. During this period, it is necessary to avoid spicy and irritating foods, as well as avoid drinking strong alcohol, strong tea, coffee, and so on. It is recommended to consume more fresh vegetables and fruits rich in vitamins, as well as nutritious and light foods. Smoking and drinking alcohol should be avoided, and meals should be regular and in measured quantities. Since sweet foods are not considered spicy or irritating, they can be consumed during the treatment of Helicobacter pylori. After the treatment of a Helicobacter pylori infection, it is necessary to wait one month after stopping the medication before a follow-up examination to confirm whether the bacteria have been completely eradicated.

Is Helicobacter pylori three pluses serious?

Three pluses for Helicobacter pylori indicate that there is an infection with Helicobacter pylori, and the level of infection is not low. Helicobacter pylori is the main cause of chronic gastritis, peptic ulcers, and even stomach cancer. If a person tests positive for Helicobacter pylori infection, and has symptoms or diseases related to the digestive system, or has a family history of stomach cancer, eradication treatment for Helicobacter pylori is necessary. The treatment involves a proton pump inhibitor plus two types of antibiotics, along with a bismuth agent, for a total of 14 days. After stopping the medication for one month, a carbon-14 breath test should be re-conducted. If the result turns negative, it means that the eradication treatment for Helicobacter pylori was successful. If it does not turn negative, remedial treatment is required.
