HP is often found in the human stomach, and if you find that you are infected with HP, or Helicobacter pylori, you are likely to experience noticeable symptoms, such as bloating in the upper stomach after a meal, belching and acid reflux at the same time. Symptoms, you need to go to the hospital for examination in time. In addition, H. pylori is often associated with gastric ulcers, gastritis and other digestive disorders.
