In addition to H. pylori and NSAIDs, there are multiple other “supportive” risk factors. These include smoking, alcohol, steroid use, and stress. Severe stress like trauma, burns and surgery may predispose to PUD. These ulcers sometimes have special names: ''Curling-ulcus'' after severe burn injury, and ''Cushing-ulcus'' after CNS injury.

Symptomatic peptic ulcers present with epigastric pain or discomfort, as well as other non-specific symptoms like bloating, abdominal fullness, and nausea. The symptoms of duodenal ulcers frequently improve with eating and worsen a few hours after meals and at night. The symptoms of gastric ulcers worsen with eating.

Treatment involves treating the underlying cause, removing risk factors, and giving PPIs.

Surgical treatment is necessary for the treatment of complications like perforation, bleeding (if endoscopic haemostasis fails), pyloric stenosis, cases which don’t respond to conservative therapy, or if malignancy is discovered.

Perforations and bleeding ulcers may be simply sutured or closed with a patch, or they may be treated with partial gastric resection and reconstruction surgeries like Billroth I, Billroth II, or Roux-en-Y. Many years ago, vagotomy was performed to reduce the production of stomach acid.

== Zollinger-Ellison syndrome ==
Zollinger-Ellison syndrome is a rare cause of PUD. It is characterized by multiple peptic ulcerations in the stomach, duodenum and even jejunum. It is caused by neuroendocrine tumors that produce gastrin, called gastrinomas, and they are often located in the pancreas, duodenum or the lymph nodes of the abdomen. Increased gastrin means increased stomach acid.
