The most common reasons for stomach pain every morning include indigestion, acid reflux or GERD, peptic ulcers, constipation, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), stress, and sometimes gastritis. Some of these conditions cause stomach pain that tends to be worse when the stomach is empty, such as ulcers and acid reflux. Others may involve changes in bowel movements like constipation or diarrhea causing abdominal pressure and pain. Stress can also make the gut more sensitive and lead to morning stomach discomfort. If the pain is severe, persistent, or accompanied by symptoms like blood in stool, vomiting, weight loss, or difficulty with bowel or urinary functions, medical evaluation is important to rule out serious conditions.
