A duodenal ulcer occurs in the small intestine, also known as the duodenum. Acids in the stomach break down the lining in the intestine causing swelling or an ulcer. Symptoms include nausea, abdomen pain, vomiting, frequent hunger, and weight loss.
Treatment for duodenal ulcers includes taking medication and cutting down on foods or habits that can cause ulcers. Drug classes used to treat duodenal ulcers are proton pump inhibitors, histamine-2 antagonists, aluminum complexes, proton pump inhibitor / penicillin / macrolide antibiotic combinations, and nitroimidazole / tetracycline antibiotic combinations.
