Why Skipping Breakfast Causes Stomach Pain

Experiencing abdominal pain when skipping breakfast could be due to increased gastric acid secretion or overly active digestion. This is commonly seen in conditions such as duodenal ulcers. Scientifically, maintaining three regular meals a day supports proper digestive function. After a long night without food, the stomach and intestines are empty, placing the body in a fasting state. During this time, gastric acid continues to be secreted rhythmically, and its production often increases in the morning. Without breakfast to neutralize the acid, it may irritate the stomach lining, leading to discomfort or pain in the upper abdomen. Eating can often relieve this pain by reducing the direct contact of acid with the stomach walls.

Duodenal ulcers are characterized by recurring, rhythmic abdominal pain that often correlates with eating patterns. People with this condition may feel pain when hungry, which subsides after eating. The pain can worsen during early morning hours and tends to flare up seasonally—especially during the transition from winter to spring or at the start of winter. This pattern is closely linked to Helicobacter pylori infection, a common cause of ulcers.

If you frequently experience hunger-related stomach pain or other digestive symptoms, it's important to consult a healthcare provider. A proper diagnosis can identify underlying issues like ulcers or H. pylori infection, allowing for targeted treatment. Ignoring these symptoms may lead to complications such as bleeding or perforation of the stomach or intestine. Early medical intervention is key to managing and preventing further digestive problems.
