How H Pylori Causes Stomach Cancer: Helicobacter pylori, a common bacteria living in the stomach, is considered one of the major causes of stomach cancer worldwide. According to a study published in Nature Medicine, about 76 percent of gastric cancer cases may be related to this bacteria. Researchers estimate that about 16 million people born between 2008 and 2017 may develop stomach cancer at some point in their lives, out of which about 12 million cases may be directly related to Helicobacter pylori infection. This bacteria lives in the inner lining of the stomach and can often exist for a long time without any obvious symptoms. Although many people are not aware of it, in some cases it can cause stomach ulcers and in severe cases gastric cancer.
What do experts say?
According to experts, the highest number of cases of stomach cancer related to Helicobacter pylori may be seen in Asia, where about 80 lakh cases have been estimated, while in North and South America together, about 15 lakh cases have been estimated. This is the reason why doctors consider it very important to identify this infection, because it is a risk factor for cancer which can be prevented in time.

Apart from this, people who have a family history of stomach cancer, smokers, obese people, those who eat excess salt or processed foods and people above 60 years of age are also considered to be at higher risk.
What are its symptoms?
Helicobacter pylori infection can sometimes remain without symptoms for years, but about 30 percent of people may develop problems related to it. Its signs include burning sensation or pain in the stomach, feeling full after eating small amounts, nausea, frequent belching, indigestion, flatulence or weight loss without any reason. If these symptoms persist for a long time then it is necessary to get checked by a doctor. Some lifestyle steps can also be helpful in reducing the risk of stomach cancer. It is important to eat a balanced diet that includes fruits, vegetables and whole grains, do regular physical activity, avoid smoking and limit alcohol consumption.
