Gastric cancer is a cancer of the stomach. An estimated 21,600 people in the United States were diagnosed with this cancer in 2013. Gasteric cancer is the second most common cause of cancer-related deaths in the world. 1
Yes. Infection with H.pylori is the primary identified cause of some gastric cancers.
Twenty-five million Americans suffer from ulcers. An ulcer is a sore or hole in the lining of the stomach or duodenum (the first part of the small intestine). People of any age can get an ulcer and women are affected just as often as men.
Helicobacter pylori (H. pylori) is a bacterium that lives on the lining of the stomach. Although we used to think that spicy food, acid, and stress were the major causes of ulcers, we now know that 9 out of 10 ulcers are caused by H. pylori. Medicines that reduce stomach acid may make you feel better, but your symptoms may come back. Here's the good news – since most ulcers are caused by this bacterial infection, it can be cured with the right antibiotics.
The most common ulcer symptom is a gnawing or burning pain in the abdomen between the breastbone and the belly button. The pain often occurs when the stomach is empty, between meals and in the early morning hours, but it can occur at any other time. It may last from minutes to hours and may be relieved by eating food or taking antacids. Less common symptoms include nausea, vomiting, or loss of appetite. Sometimes ulcers bleed. If bleeding continues for a long time, it may lead to anemia with weakness and fatigue. If bleeding is heavy, blood may appear in vomit or bowel movements, which may appear dark red or black.
Your health care provider may choose to use any of the following tests to determine if your ulcer is caused by H. pylori:
Stool test: A simple stool test can determine if you are infected with H. pylori. In this test, you provide a small stool specimen (an easy-to-use collection system is provided for this purpose). The doctor will conduct the test in his office or send it to a laboratory.
Breath test: A breath test can determine if you are infected with H. pylori. In this test you have to fast then a breath sample is taken after you wait and drink a 13C-labeled urea mix. The breath sample collected is then analyzed in the office or send out to a laboratory.
Endoscopy: Your health care provider may decide to perform an endoscopy. This is a test in which a small tube with a camera inside is inserted through the mouth and into the stomach to look for ulcers. During the endoscopy, small samples of the stomach lining can be obtained and tested for H. pylori.
If you are tested for H. pylori, and if found to be infected, you should be treated with antibiotics. Antibiotics offer a new cure for ulcers; therapy is 1-2 weeks of one or two antibiotics plus a medicine that will reduce the acid in the stomach. This treatment is a dramatic medical advance because eliminating H. pylori with antibiotics means that there is a greater than 90% chance that the ulcer can be cured for good. Remember, it is very important to continue taking all of this medicine until it is gone, even when you begin to feel better. If you are having side effects that make it hard to take your medicine, talk to your health care provider.
Dyspepsia, or indigestion, is a chronic pain or discomfort of the upper abdomen. It's very common. To help patients understand if they have dyspepsia, you can provide a simple questionnaire.
