What is Duodenitis? Causes, Symptoms and Treatment

What is duodenitis?

Duodenitis is an inflammation that occurs in the duodenum (duodenum), which is the beginning of the small intestine. Inflammation of the duodenal lining can cause abdominal pain , bleeding, and other symptoms related to the digestive system. The most common cause of duodenitis is a stomach infection associated with a type of bacteria called Helicobacter pylori (H. pylori) . This organism disrupts the barrier of the duodenum due to acidic stomach contents. Loss of this barrier can lead to chronic inflammation and trigger duodenal ulcers.

Many people become infected with H. pylori at a young age, but symptoms often do not appear until adulthood. In some people, H. pylori infection causes duodenitis, which, if left untreated, can lead to ulcers (open sores) in the duodenum. Severe diseases, the use of various drugs, and things like alcohol or tobacco are also causes of duodenitis . Another less common cause is an inflammatory bowel disease called Crohn’s disease.

The symptoms of duodenitis may be constant or come and go, the course of the disease differs between individuals. If the cause is H. pylori, your symptoms will continue unless the infection is treated. Some people with duodenitis have no symptoms, while others may experience nausea, vomiting, and a burning sensation in the stomach.

In the case of duodenitis associated with H. pylori, the infection can be successfully treated with antibiotics . For duodenitis not associated with H. pylori, medications that reduce stomach acid can be an effective treatment. You can also reduce your risk of H. pylori infection by following common sense hygiene practices, such as washing your hands with soap and water. Lifestyle changes, such as limiting alcohol consumption and taking medications only on doctor’s advice, can reduce your risk of duodenitis unrelated to H. pylori.

antibiotic therapy

If your duodenitis is caused by an H. pylori infection, the mainstay of treatment is antibiotic therapy. It is important to follow your antibiotic treatment exactly to avoid re-infection or recurrence. For antibiotic treatment, you may need to use drugs containing the following active ingredients:
