What is H. Pylori?

H. pylori is a bacterium and a leading cause of ulcers in children. It:

  • is able to penetrate the stomach's protective mucus lining
  • produces the enzyme urease, which damages your child's stomach acids
  • leads to sores or ulcers in the stomach or duodenum (first part of the small intestine)
  • can also stimulate the stomach to produce more acid

What are the symptoms of H. pylori-related ulcers?

Most children or adults first develop gastritis: an inflammation of the stomach lining. Many will never have symptoms. Some symptoms are:    

  • dull, gnawing pain
  • loss of weight
  • loss of appetite
  • bloating
  • burping
  • nausea
  • vomiting
