Overview
Helicobacter pylori (H. pylori) is a spiral-shaped bacterium that infects the stomach lining of about half of the world's population — and is especially common in Saudi Arabia and the wider Middle East. Most people have no symptoms, but in others it causes chronic gastritis, peptic ulcers, and a small but real increase in the risk of stomach cancer. The good news: it can almost always be cured with a 10–14 day course of antibiotics combined with acid-suppressing medication.
Symptoms
Burning or gnawing pain in the upper abdomen (often worse on an empty stomach)
Bloating and frequent belching
Nausea or loss of appetite
Unintended weight loss
Iron-deficiency anemia (sometimes the only sign)
Indigestion despite acid-blocker medication
How It Spreads & Risk Factors
Spread mostly in childhood through saliva, contaminated food, or water
Crowded living conditions and shared utensils increase risk
A family member with confirmed infection
Living in or coming from a region with high prevalence (e.g. Saudi Arabia)
Poor sanitation in early life — the strongest risk factor
It is NOT caused by stress or spicy food
Testing & Treatment
Three reliable tests: urea breath test, stool antigen test, or biopsy during endoscopy
Stop proton-pump inhibitors (omeprazole, esomeprazole) for 2 weeks before testing — they cause false negatives
Stop antibiotics for at least 4 weeks before testing
Standard treatment: a combination of two antibiotics plus a proton-pump inhibitor for 14 days
Take ALL doses — incomplete treatment leads to resistance and treatment failure
Retest 4–8 weeks after finishing antibiotics to confirm eradication
If first treatment fails, a different antibiotic combination usually works
When to See a Doctor
See a doctor if you have persistent stomach pain, unexplained weight loss, vomiting blood, black tarry stools, or trouble swallowing — these can suggest a bleeding or complicated ulcer. Anyone in the family of a confirmed case, or anyone with iron-deficiency anemia, persistent indigestion, or a family history of stomach cancer, should be tested.
