Most people have the H. pylori bacteria for years without knowing it because they don’t have any symptoms. Experts don’t know why.
After being infected with H. pylori, your child may have an inflammation of the stomach lining. This is called gastritis. But most people never have symptoms or problems from the infection.
When symptoms do occur, they may include belly pain, which can:
- Be a dull, gnawing pain
- Happen 2 to 3 hours after a meal or immediately after
- Come and go for a few days or weeks
- Occur in the middle of the night when your child’s stomach is empty
- Be eased by eating or taking an antacid medicine
Other symptoms may include:
- Loss of weight
- Loss of appetite
- Swelling or bloating
- Having an upset stomach or nausea
H. pylori symptoms may look like other health conditions. Always see your child's healthcare provider for a diagnosis.
