H. pylori or Helicobacter Pylori Helicobacter pylori (most commonly referred to as “H. pylori”) is a medical condition diagnosed by our NYC gastroenterologists, that is isolated to the upper gastrointestinal tract.  Helicobacter Pylori, also known as H. Pylori is a very common infection worldwide. In fact, it is the most common chronic stomach bacteria infection in humans. By some estimates, it may be present in up to one half of the world’s population. The estimated prevalence being up to 70% in developing countries and 30­ – 40% in the United States and other developed countries. In most individuals, the bacteria will be without symptoms and not lead to any long term health affects. The bacteria is found in the stomach and can sometimes cause pain in the upper abdomen, bloating and nausea in some patients.

The diagnosis of management of h. pylori should be managed by a trained gastroenterologist. In general, individuals should be tested for h.pylori if they have or have had ulcers in the stomach or duodenum. H. Pylori symptoms can have many symptoms including ulcer disease, upper abdominal pain, bloating nausea. There are however, many other causes of ulcers, particularly patients taking non­steroidal anti-­inflammatory medications. Further, patients with these symptoms may need further testing in addition to evaluation for h. pylori. Sometimes patients with a family history of stomach cancer are tested for h. pylori as well.

H. pylori or Helicobacter Pylori Helicobacter pylori

H. Pylori is probably spread by consuming food or water contaminated with fecal matter. Contaminated water supplies in developing countries may account for some of the higher prevalence of this infection in those countries. After exposure, H. Pylori can then infect the lining of the stomach and release enzymes and toxins that can inflammation and injure the cells linking the stomach or duodenum. In the US, infection is uncommon during childhood and becomes more common as an adult whereas in developing countries, most children are affected at a young age.

After one is diagnosed with h.pylori, an antibiotic regimens are usually prescribed.  There are several different regimens that are approved and effective. It is important that patients make sure to take the entire regimen.  If the bacteria is found, it should be treated because that will help ulcers heal, decrease recurrence rates and may decrease more rare long term consequences of h.pylori.  Treatment for H. Pylori gastritis is generally effective but there are some individuals who are not cured from therapy. Up to 20 percent of patients, may not be cured with a first course of treatment. In these patients, a different antibiotic regimen may be used as prescribed by their doctor. In addition, a breath test or stool tests should be done to document cure after treatment.

There are many tests to diagnose h. pylori.

Invasive testing such as upper endoscopy may be needed and biopsies can be taken to evaluate for the presence of h. pylori. Please see your gastroenterologist for evaluations of symptoms and formulation of an effective treatment plan.
