The new year is an annual time for family reunion. It's fun for relatives and friends to have dinner and drink. However, when dining in groups, many people still have not used the public chopsticks or serving of individual dishes, which gives the pylori a good chance to use. "Helicobacter pylori is mainly transmitted between people through mouth-to-mouth transmission, fecal mouth transmission, stomach mouth transmission and other ways. Intra family transmission is one of the main ways of infection. It is advocated that families divide meals or eat with public chopsticks and spoons." Peng ya, director of general internal medicine of Hunan Provincial People's Hospital, said. Peng Ya said that after infection with Helicobacter pylori, some people may not have any symptoms. Some people may have symptoms of chronic gastritis such as epigastric discomfort, acid reflux, heartburn, belching, halitosis and stomach pain. About 10% of patients develop serious gastrointestinal diseases such as peptic ulcer. So, how do you know you are infected with Helicobacter pylori? Peng Ya introduced that Helicobacter pylori detection methods are divided into invasive and non-invasive detection methods. Invasive detection method refers to the detection of biopsy samples taken during gastroscopy, including rapid urease test, pathological tissue section, bacterial culture and gene detection. Non invasive detection methods include serum HP antibody, serum antigen and isotope tracing. Isotope tracing method includes 13 carbon urea breath test and 14 carbon urea breath test. It is a commonly used clinical detection method. It judges whether there is Helicobacter pylori infection by allowing subjects to take orally labeled urea and collecting the exhaled gas regularly. "Compared with the traditional 14 carbon urea breath test, the 13 carbon urea breath test has the advantages of no radiation and safer. It is applicable to children, pregnant women and the elderly except the general population." Said penya. What if you are unfortunately infected with Helicobacter pylori? Peng Ya said that in addition to developing healthy living habits such as using public chopsticks, dividing meals and washing hands before and after meals, early screening, sterilization and stomach treatment, prescription and accurate treatment are the key after Helicobacter pylori infection is confirmed. If the person with positive Helicobacter pylori test is accompanied by obvious symptoms of gastric discomfort, or has a family history of stomach disease and gastric cancer, he / she needs to undergo further examination of gastroscope under the guidance of the doctor and decide the treatment plan according to the examination results. The specific treatment plan needs to be prescribed by a digestive specialist in a regular hospital, and the medication should be standardized according to the doctor's advice. (outlook new era)
