Have you ever experienced persistent stomach discomfort, unexplained bloating, or recurring indigestion that just won’t go away? One of the most common culprits worldwide is Helicobacter pylori (H. pylori) infection. This tiny bacterium affects millions of people, often going unnoticed for years. While not everyone develops symptoms, untreated infections can lead to gastritis, peptic ulcers, and even increase the risk of stomach cancer in some cases.

The good news? H. pylori can be diagnosed and treated effectively. At Reem Hospital, our specialist gastroenterologist provide comprehensive testing, advanced treatment options, and personalized care plans to help patients manage and overcome this condition.

What Is H. pylori?

  • H. pylori is a spiral-shaped bacterium that can survive the harsh acidic environment of the stomach.
  • Many people live with it asymptomatically, but it can lead to problems such as gastritis, peptic ulcers, and other gastrointestinal symptoms.

What Causes H. pylori Infection?

Some of the common causes and risk factors:

  • Transmission typically occurs via contaminated food or water, or through close person-to-person contact (saliva, etc.). 
  • Poor sanitation, overcrowding, and living in settings with limited clean water increase the risk. 
  • Dietary habits: high intake of processed foods, refined carbohydrates, sugary drinks, or foods preserved with high salt may increase risk. 
  • Sometimes, weakened immunity or other medical factors play a role.

How Do I Know If I Have H. pylori? (What Happens If You Test Positive?)

If you test positive or have symptoms, here’s what usually happens:

  • Symptoms may include persistent stomach pain or burning, bloating, nausea, frequent burping, loss of appetite, or unexplained weight loss. 
  • To confirm, your doctor can order H. pylori tests:
    • Breath tests 
    • Stool antigen tests 
    • Blood antibody tests (though these are less ideal for checking if the infection is cleared) 
    • Endoscopy with biopsy, especially in complicated or persistent cases 
  • If positive, treatment is generally recommended: to relieve symptoms, heal ulcers (if present), and prevent possible complications.

H. pylori Antigen in Stool

A stool antigen test is a simple, non-invasive way to detect an active H. pylori infection. It works by identifying H. pylori proteins (antigens) in a small stool sample.

  • When it’s used: Both for initial diagnosis and to confirm that treatment worked.
  • Advantages: Easy to perform, no endoscopy needed, highly accurate.
  • Tip: Patients should stop certain medications (like PPIs or antibiotics) before the test to avoid false negatives — your doctor will guide you.

H. pylori Antibody Test

A blood test can detect antibodies your body makes against H. pylori.

  • Pros: Simple and quick.
  • Limitations: It only shows that you were exposed to H. pylori at some point. Antibodies may stay in the blood even after the infection is gone, so it’s not the best way to check if treatment worked.

H. pylori Breath Test Instructions

The urea breath test is considered the gold standard for diagnosis.

  • How it works: You drink a solution containing urea. If H. pylori is present, the bacteria break it down and release carbon dioxide, which is measured in your breath.
  • Before the test:
    • Avoid antibiotics for at least 4 weeks prior.
    • Stop proton pump inhibitors (PPIs) for 2 weeks.
    • Fast for 4–6 hours before the test.
  • Advantages: Highly accurate and non-invasive.

Is H. pylori Contagious?

Yes, H. pylori is contagious, though not easily compared to viruses like the flu. It spreads:

  • Through contaminated food or water.
  • By person-to-person contact, especially saliva.
  • More common in families or communities where close contact and shared food occur.

Maintaining good hygiene and safe food practices helps reduce the risk.

Does H. pylori Go Away on Its Own?

Unfortunately, H. pylori does not usually go away on its own. Without treatment, it may persist for years, sometimes for life.

  • In some people, it may remain silent.
  • In others, it can cause chronic gastritis, ulcers, or long-term complications.
  • Treatment is necessary to fully clear the infection and protect the stomach lining.

How to Remove H. pylori from the Stomach (H. pylori Treatment)

Treating H. pylori usually involves a combination of therapies. Common components:

  1. Antibiotics: Usually two or more types to overcome possible bacterial resistance. Common ones include amoxicillin, clarithromycin, metronidazole. 
  2. Proton Pump Inhibitors (PPIs): These reduce stomach acid, creating a better environment for healing. 
  3. Bismuth-based compounds: Sometimes used, especially when resistance is a concern. 
  4. Duration of treatment: Typically 10-14 days, depending on the protocol. Finishing the full course is critical. 

What Foods Should I Avoid with H. pylori?

Adjusting diet won’t cure H. pylori alone, but can reduce irritation, support healing, and improve comfort.

Foods and beverages to limit or avoid:

  • Spicy foods (e.g. hot peppers, strong sauces) that irritate the stomach lining. 
  • Acidic fruits (like citrus) and acidic drinks that increase stomach acid. 
  • Foods and drinks with caffeine (coffee, some teas, chocolate), which stimulate acid production. 
  • Alcohol — it can damage the mucosal lining and slow healing. 
  • Fried, fatty foods, and heavily processed foods that are harder to digest and may worsen symptoms. 

Helpful dietary additions:

  • Foods rich in probiotics (yogurt, kefir) to help restore healthy gut flora. 
  • Plenty of fruits and vegetables, whole grains, and sources of omega-3 fats (fish, olive oil) which have anti-inflammatory properties.

Why Early Detection & Treatment Matter

Left untreated, H. pylori infection can result in:

  • Peptic ulcers
  • Chronic gastritis
  • Long-term risk of complications, such as gastric cancer in some individuals

At Reem Hospital, we offer full diagnostic services, personalized treatment plans, and expert guidance for diet and follow-up care so you can heal comfortably and avoid complications.

Conclusion

Early detection and proper treatment of H. pylori can make a significant difference in preventing serious health issues. Don’t ignore the symptoms — get tested and treated promptly to protect your digestive health and overall well-being.
