Most patients have no obvious symptoms after infection with Helicobacter pylori, and a small number of patients may experience symptoms such as bloating and belching (burping), which usually do not directly trigger indigestion. If timely intervention is not possible, it can develop into a digestive disease that can cause indigestion. After being infected with Helicobacter pylori, most patients often have no conscious symptoms and can only be found accidentally during an examination. In some cases, H. pylori infection does not usually cause indigestion. If not intervened in time, with the development of the disease, it can gradually develop into peptic ulcer, chronic gastritis, or even gastric cancer, which will lead to dyspepsia. Once diagnosed, patients should pay attention to the condition and seek medical attention as soon as possible.
