Quick Answer: Gastritis is inflammation of the stomach lining that can cause stomach pain, nausea, and vomiting in children. Common causes include H. pylori infection, medications (like NSAIDs), and stress. Most cases improve with dietary changes and medications. See a doctor if your child has persistent stomach pain, blood in vomit or stool, or unexplained weight loss.

Frequently Asked Questions
Q: Can stress really cause stomach problems in children?
A: Yes! Stress can increase acid production and affect the stomach lining. While gastritis from pure stress is less common in children than adults, emotional stress can worsen existing gastritis.
Q: How long does it take for gastritis to heal?
A: Acute gastritis may resolve in days to weeks with proper treatment. Chronic gastritis may take longer - months of management. H. pylori gastritis improves after successful antibiotic treatment.
Q: Can my child eat normally with gastritis?
A: Some modifications are needed during active symptoms. Once healed, most children can return to a regular diet while avoiding known triggers. Some children remain sensitive to certain foods.
Q: Is gastritis in children serious?
A: Most cases are mild and treatable. However, untreated gastritis can lead to ulcers or bleeding, which is why persistent symptoms should be evaluated.
Q: My child often complains of stomach ache. Is it always gastritis?
A: Not necessarily. Stomach aches in children have many causes - constipation, stress, food intolerance, infections. Gastritis is one possibility. A doctor can help determine the cause.
