How to Know if You Have H. Pylori

A guide for identifying symptoms and getting a medical test

Helicobacter pylori (H. pylori) is a bacteria that causes chronic inflammation of inner lining of the stomach and is the leading cause of peptic ulcer disease worldwide. Over 50% of American people are infected with H. pylori and, in developing countries, the percentage may reach as high as 90%; however, only one in six persons develops symptoms of peptic ulcer. The only way to know for sure if you are infected is getting tested by a medical professional.

Recognizing the Symptoms

    1
    Watch for dull pain in your stomach that does not go away.[1] An H. Pylori infection can cause peptic ulcers in your stomach and lower intestine. As H. Pylori rarely causes symptoms in and of itself, a peptic ulcer can alert you to a potential infection. If you have a peptic ulcer, you may display some of the following symptoms:[2]
    • You may have a dull pain in your stomach that does not go away. Pain will usually come two to three hours after eating.
    • The pain will come and go for several weeks, and may sometimes happen in the middle of the night when your stomach is empty.
    • The pain may go away temporarily when you take medications like antacids and other over-the-counter pain medications.

    Pay attention to prolonged nausea. You may experience nausea if you have an H. Pylori infection.[3] Pay attention to your body and notice of any nausea you experience.[4]
    • You may vomit when you experience nausea. With an H. Pylori infection, your vomit may include blood. You may also notice a substance that resembles coffee grounds.
    • Nausea can be caused by a wide variety of factors, such as motion sickness, the flu, eating or drinking something that did not sit well with you, or morning sickness during pregnancy. If your nausea is persistent, and you do not have any obvious cause, it may be related to an H. Pylori infection.

    Consider your appetite. A loss of appetite can also be a symptom of an H. Pylori infection. You may not be interested in food or eating. This may come in conjunction with the feelings of nausea and indigestion associated with the disease.[5]
    • If you're having a loss of appetite, which is accompanied by unexplained weight loss, you may want to talk to a doctor. Loss of appetite is a common symptom of many diseases, including some cancers.[6] See your doctor to rule out any serious conditions if you're experiencing a loss of appetite.

    Watch out for unusual changes in your body. You may experience some odd changes in your body when you have an H. Pylori infection. Take note of any sudden changes and see a doctor for evaluation.[7]
    • It's not uncommon for the abdomen to be bloated slightly during an H. Pylori infection.
    • You may also notice your stools have become increasingly black and tarry.
    • Sometimes, people with an H. Pylori infection will experience frequent bouts of the hiccups.
  5. Image titled Stop Yourself from Crying Step 14

    Assess your risk factors. As symptoms are rare, and easily mistaken for other conditions, think about your risk factors. If you have a lot of risk factors for an H. Pylori infection, symptoms like stomach cramps may be cause for concern.[8]
    • If you live in crowded conditions, such as a small home with many people, this increases your risk of infection.
    • If you don't have regular access to clean water, you may also have an increased risk of infection.
    • If you live in a developing country, or have recently visited one, this also increases your risk for infection.
    • If you're living with someone who you know has H. Pylori, this means you're more likely to have the infection yourself.

    Seek immediate medical attention if symptoms get worse quickly. H. Pylori is not usually a medical emergency; however, some symptoms can become serious. If you experience any of the following, seek immediate medical attention:[9]
    • Difficulty swallowing
    • Severe abdominal pain
    • Bloody stools
    • Bloody vomit

Seeking Medical Testing

    1
    Talk with your doctor about testing. Talk to your doctor about your symptoms and why you think you may have H. Pylori and see if she agrees that a test is necessary. People who should be tested for H. Pylori include those with certain gastric tumors, active peptic ulcer disease, or history of peptic ulcer disease. People who are under the age of 55 who have dyspepsia may be candidates for treatment.
  2. Image titled Sing Using Your Diaphragm Step 3
    2
    Take a breath test.[10] Though this is not the most accurate test for H. Pylori, it is not as invasive as some other options. During this test, you swallow a substance that contains a waste product called urea. Urea breaks down proteins in the stomach. If an infection is present, the urea will be converted to carbon dioxide which can be detected in the breath.[11]
    • You will need to prepare for a breath test for about two weeks. Your doctor will advise you to stop taking any over-the-counter or prescription medication you're using to treat H. Pylori.
    • You will swallow the urea in the doctor's office. After 10 minutes, you'll be asked to exhale and the doctor will test your breath for carbon dioxide.
  3. Image titled Take a Stool Sample Step 2
    3
    Consider a stool test.[12] Your doctor may want to test your stool for traces of H. Pylori. This is usually done after treatment to confirm H. Pylori has been eradicated and you no longer have an infection.[13]
    • Your doctor may order a stool test after a positive breath test and subsequent treatment.
    • Listen to your doctor's instructions carefully in regards on how to collect and store your stools. Collection methods vary by hospital.
    • There is also a rapid stool antigen test for H.Pylori. Talk with your doctor about this option — it may not be available everywhere.
  4. Image titled Pass a Tobacco Test Step 2
    4
    Get a blood test done.[14] A blood test can also be used to check for H. Pylori; however, this test may not be as accurate as a breath test. It can only test whether your body currently contains H. Pylori antibodies. It cannot tell if you are presently infected.[15]
    • Your doctor may order a blood test for a variety of reasons. She may want to confirm an infection. If your doctor orders a blood test, trust that your doctor knows what's best for you. It's a simple procedure that should not take long.
    • Other methods that are not as commonly utilized include PCR chain reaction, salivary assays, urinary assays, and C13-urea blood test.
  5. Image titled Cure Nausea Step 9
    5
    See if your doctor wants a biopsy. A biopsy is the most accurate way to test for H. Pylori.[16] In a biopsy, a small tissue sample is taken from your stomach. You'll have to have an endoscopy, a somewhat invasive medical procedure, conducted at the hospital to remove the sample.[17]
    • During an endoscopy, a small tube will be inserted into your mouth and then fed into your stomach. In addition to removing a tissue sample, your doctor will check for inflammation.[18]
    • While the most accurate means to diagnose H. Pylori, your doctor will not call for this procedure unless an endoscopy is necessary for other reasons. Your doctor may want to conduct an endoscopy if you have a peptic ulcer or are at risk for stomach cancer.

Coping with an Infection

    1
    Take drugs to suppress acid. After an infection is diagnosed, your doctor will recommend you take a variety of drugs to suppress stomach acid. Triple antibiotic therapy is the first line treatment for H. Pylori. The regimen most commonly employed for first line treatment include a proton pump inhibitor and two antibiotics for coverage against the bacteria. Treatment should last 14 days. Your doctor will recommend which particular drugs are best for you based on your medical history and current condition.[19]
    • Proton pump inhibitors (PPIs) are a range of drugs that stop acid production in the stomach. Your doctor may prescribe these drugs if excessive stomach acid is causing you pain.
    • Histamine (H-2) blockers can also block acid production by stopping the production of a substance called histamine. Histamine can trigger acid production in the stomach.
    • Bismuth subsalicylate, sold commercially as Pepto-Bismol, can coat stomach ulcers and can reduce pain.
    • Follow your doctor's instructions carefully in regards to which drugs he recommends. If you are on any existing medication, make sure to ask whether your current meds will interact with medication used to treat H. Pylori.
  2. Image titled Decrease Gas Caused by Fiber in Diet Step 10

    Continue testing throughout treatment. Your doctor will want to make sure treatment of your H. Pylori was successful. He or she will probably want to do another round of testing about four weeks after your treatment. In the event treatment was unsuccessful, you may undergo a second round of treatment and be prescribed antibiotics. Usually the second round of testing includes upper endoscopy, fecal antigen test, or urease breath test for confirmation of eradication.
  3. Image titled Deal With Unexplained Pains Step 22
    3
    Talk to your doctor about whether regular screenings are right for you. You may want to be regularly screened for H. Pylori if you have a high risk of stomach cancer. An H. Pylori infection may increase your risk of developing stomach cancer. Discuss your concerns with your doctor and she will decide if regular screening for H. Pylori is right for you.[20]
