Why do I get stomach pain when I'm hungry?

Pain that arrives when you are hungry and fades when you eat is one of the most specific patterns in digestion: gnawing or burning in the upper middle belly, appearing two to three hours after meals and overnight, reliably relieved by food or antacids. That is the classic signature of a duodenal ulcer - an open sore where the small intestine begins, bathed in stomach acid that food temporarily buffers. The NHS describes exactly this pattern for ulcers, including pain that wakes people at night. The main causes are H. pylori bacteria - present in a large share of the population - and regular NSAID use like ibuprofen. Why to take it seriously: ulcers are very treatable - H. pylori gets a breath, stool, or blood test and a two-week eradication course; acid suppression heals the lining - and ignoring them invites bleeding or perforation. The danger signs: vomiting blood or coffee-ground material, black tarry stools, sudden severe abdominal pain, or dizziness and pallor suggesting slow blood loss - all urgent. Before the appointment: eat on schedule rather than skipping meals, cut NSAIDs in favor of alternatives your provider approves, ease off alcohol, coffee, and smoking - all ulcer aggravators - and use pharmacy antacids for comfort. Mild hunger discomfort that only appears with genuine fasting and vanishes with a snack can be normal physiology; the recurring gnawing pattern with night pain is not.
