Peptic ulcer

A peptic ulcer is an ulcer of the stomach or duodenum. The duodenum is the first part of the small intestines. It is the tube that food goes through when it leaves the stomach. Peptic means talking about the stomach.

Gastric ulcers are peptic ulcers in the stomach.

Duodenal ulcers are peptic ulcers in the duodenum.

 Global statistics 

The lifetime risk for developing a peptic ulcer is approximately 5% to 10%. Men and women are equally as likely to have them. 

The amount of deaths was much higher until the last decades of the 20th century, then dropped. 

Deaths caused by peptic ulcer deaths globally in 2015 was 267,500.

 Causes 

Most ulcers are caused by an infection from bacteria. This bacteria is called Helicobacter pylori. 90% of gastric ulcers and 75% of duodenal ulcers are from Helicobacter pylori infection.

Other things can make ulcers worse. But these things are less important than Helicobacter pylori. These other things are:

 Drugs called NSAIDs, medicine used for pain and inflammation. Aspirin, ibuprofen, and naproxen are NSAIDs. 
 Smoking cigarettes
 Old age
 Stress from diseases or injuries like pneumonia and burns

 Symptoms and signs 
The most frequent symptom is pain in the stomach. Pain is usually in the top of the abdomen below the ribs. Some people also feel pain go up to the chest.

Other symptoms are:
 Vomiting
 Blood in vomit – this can be red. This can also look like coffee grounds
 Black stools
 Waves of Pain or Burning
Vomiting red blood while having other symptoms is a serious sign.

 Diagnosis 
 Endoscopy – looking inside a person's stomach with a camera that goes through their mouth and down to their stomach
 Test on the air someone breathes out to look for Helicobacter pylori infection
 Blood test to look for Helicobacter pylori infection
 Feces antigen test
 Small sample taken from the affected body area or the ulcer
 X-Ray: imaging of the GI tract. Ulcers in the body can be found this way, also called an upper GI series 

The best way is endoscopy. But this costs more money. Endoscopy is done by a medical specialist called a gastroenterologist (a doctor who knows much about the digestive system.)

A good thing about endoscopy is finding other diseases if there is no peptic ulcer. The symptoms of peptic ulcer can be from other diseases. Endoscopy can diagnose these other diseases.

 Treatment 
Treatment often entails the use of antibiotics to kill H. pylori; reducing or stopping the use of NSAIDs; and reducing or blocking the effects of stomach acid to assist in the ulcer's healing. Antacids such as Proton Pump Inhibitors (PPIs) or H-2 Blockers may be used to reduce stomach acid, or cytoprotective agents such as sucralfate or misoprostol may be used to protect the stomach lining from the acid.
