Symptoms of Duodenal Ulcer If you have a small duodenal ulcer you may not experience any symptoms. Abdominal pain is a common symptom but not always present. Other symptoms can include belching, fatigue, heartburn, indigestion, chest pain, weight loss, nausea, vomiting and bloody stools. Symptoms vary by person so see your doctor if you are concerned.
ComplicationsLarge duodenal ulcers or ulcers that have caused a hole in the intestine can cause internal bleeding. Obstructions at the opening of the stomach and intestine can also occur. Duodenal ulcers can cause inflammation in tissues lining the abdominal walls. If the intestine is perforated the acid can leak out and cause damage to surrounding organs. Perforations need immediate medical attention to control internal bleeding and limit damage to other organs.
