Helicobacter pylori (H. pylori) is a type of bacterium that can cause infections in the digestive tract. This type of infection is the most common cause of peptic ulcers worldwide. Symptoms of an H. pylori infection can vary, but most commonly include abdominal pain, nausea, bloating, and indigestion. Other signs may include weight loss, loss of appetite, and dark stools. The primary cause of H. pylori infection is believed to be the ingestion of contaminated food or water.

Diagnosis of an H. pylori infection is typically done via a blood test, breath test, or stool sample. Treatment typically involves a combination of antibiotics and antacids to reduce symptoms. In some cases, surgery may be necessary. It is important to note that H. pylori infections can be difficult to treat and can recur. Therefore, it is important to follow the treatment plan prescribed by your doctor.
